Distance control was tested depending upon uneven lie angles 0o, 5o, 10o and 15o using 3-wood, 6-iron, pitching club. As lie angle increases, the distance from playing a shot keeps off from the target. Increasing club number has shown to decrease the effect of the lie angle. Lie approximately 10 ° angle increasingly promotes a club. As the distance to the target increases, the uncertainty to green become large and so the effect of lie angle becomes very much larger. Therefore, adjustment training for golfer is required for lie angles depending on each club.

[목적] 본 연구는 골프 롱 퍼팅에서의 스윙 유형에 따른 거리감의 차이를 분석하여 퍼팅 시 골퍼들의 거리감을 최적화시 키는 방법을 제시하기 위함이다. [방법] 본 연구를 위해 서울에 소재한 K대학교 골프연습장에서 퍼팅분석 장비인 Quintic Ball Roll을 이용하여 Kpga/Klpga 이상의 프로골퍼 10명과 핸디캡 18-27의 아마추어골퍼 10명을 대상으로 평지 스트레이 트라인 12미터 거리의 인조매트에서 미는 스윙 방법과 때리는 스윙 방법으로 각 10회씩 수행하였으며, 도출된 자료는 SPSS 20.0을 사용하여 T-test 분석을 하였다. [결과] 각 스윙방법이 퍼팅한 볼의 거리감에 미치는 영향을 확인한 결과, 프 로골퍼들의 경우 퍼팅방법과 롱 퍼팅 거리감은 유의미한 상관관계가 없는 것으로 확인되었으나, 비숙련 아마추어골퍼들 의 경우에는 미는 스윙으로 퍼팅할 때가 때리는 퍼팅으로 스윙할 때보다 롱퍼팅에서의 거리감 조절 능력이 높아지는 것 으로 나타났다. [결론] 따라서 비숙련 아마추어골퍼들은 롱 퍼팅에서는 미는 스윙으로 거리를 조절하는 퍼팅방법을 선택 하는 것이 바람직할 것으로 판단된다.

This paper presents a movement-based analysis of control in Korean, adopting Hornstein(1999). The typical pattern of the control construction has been assumed to be confined to infinitival complements. The null subject in the infinitival complement is construed to be anaphorically dependent on the antecedent in the matrix clause. However, control in Korean is observed in CP complements as well. The issue that arises is how to license the long-distance dependency between the null subject and its antecedent crossing over CP. I show that the control dependency in Korean can be best analyzed in terms of movement in the autonomous syntax. The generalization is that control movement takes place long-distance crossing over CP regardless of finiteness of the clause. This fact is accounted for under the hypothesis that in a language without phi-agreement like Korean, the thematic subject is not raised to Spec TP, which consequently is available as an escape hatch for A-movement(Kim, 2011). The guiding idea of my analysis is that the apparent long-distance A-movement is made up of a sequence of strictly local movement. My analysis is reduced to Rizzi’s(1990) Relativized Minimality.

The aim of the study was to analyze the effect of knee compression bandage and arm swing control on the maximum horizontal distance and ground reaction force variables in standing long jump. Adult male (n=8; mean age, 22.75±1.98 years; mean heights, 1.77±0.03 m; mean weights, 71.82±12.87 kg) participated in the experiment. The results ob-tained from variables of ground reaction force (GRF) in medial lateral, anterior posterior (AP), vertical (V) direction, resultant GRF (RGRF), de-cay rate (%), and maximum horizontal distance (MHD) were as follows; MHD, AP GRF, VGRF, RGRF (AP-V), and ratio of load reduction (%) showed more effective result under both wearing of knee compression bandage and arm swing. In analysis of main effects, MHD, AP GRF, VGRF, and RGRF showed more increased value in case of wearing of knee com-pression bandage than as was not. While arm swing during standing long jump (SLJ) works as important factor to MHD, showed more effec-tive factor in exercise rehabilitation, injury prevention and swell treat-ment etc. in wearing of worn knee compression bandage. Therefore it was assumed that arm swing and wearing of knee compression ban-dage may improve the performance of SLJ. Also, the characteristics of knee compression bandage suggest that it can be a great help for those participating in exercise rehabilitation.

자율주행 시스템의 수용성 보장은 중요하다. 시스템 수용성 요소 중 하나인 자율주행 종방 향 제어기는 상위 제어기와 하위 제어기로 구성된다. 상위 제어기는 Cruise 제어와 Space 제어 를 상황에 맞는 제어를 결정하고 필요한 목표 속도를 만든다. 하위 제어기에서는 목표 속도를 추종하기 위한 가속도 신호를 만들어서 제어를 수행한다. 본 논문에서는 상위 제어기에서 Cruise 제어와 Space 제어전환 문제에서 발생하는 차간거리 변동을 개선하는 알고리즘을 제안 한다. 제안한 방법은 Cruise 제어에서 Space 제어로 전환되는 시점에 Cruise 제어에 Approach 알고리즘을 추가하여 전환 거리에서 Space 제어로 전환되도록 하는 것이다. 이를 통해서 ± 12m 초기 오차에서 ±4m까지 오차를 개선했으며 실차검증을 수행하였다.

Driver acceptance of autonomous driving is very important. The autonomous driving longitudinal controller, which is one of the factors affecting acceptability, consists of a high-level controller and a low-level controller. The host controller decides the cruise control and the space control according to the situation and creates the required target speed. The sub-controller performs control by creating an acceleration signal to follow the target speed. In this paper, we propose an algorithm to improve the inter-vehicle distance fluctuations that occur in the cruise control and space control switching problems in the host controller. The proposed method is to add an approach algorithm to the cruise control at the time of switching from cruise control to space control so that it is switched to space control at the correct switching distance. Through this, the error was improved from 12m error to 4m, and actual vehicle verification was performed.

본 연구는 자기통제의 고저 두 수준, 목표진행프레이밍의 이뤄진 진행프레이밍과 남은 진행프레이밍의 두 수준에 따라 미래 자기조절행동까지의 시간적 거리가 멀거나 가까울 때 탐닉소비의 양상이 다르게 나타나는지를 검증하였다. 그 결과, 고 자기통제자의 경우, 예상되는 목표달성에 집중하는 이뤄진 진행프레이밍을 취할 때, 먼 미래보다 확실하고 현저하게 느껴지는 가까운 미래의 자기조절행동을 상상한 후 탐닉소비가 더 증가하였다. 반대로 완전한 목표달성을 위해 예상되는 목표진행의 남은 부분에 집중하는 남은 진행프레이밍을 취할 때는 가까운 미래와 먼 미래의 탐닉소비에 통계적으로 유의한 차이가 없었다. 저 자기통제자의 경우, 미래 자기조절행동을 상상했을 때, 그 시간적 거리가 가깝거나 먼 것, 그리고 예상되는 목표진행의 이뤄진 부분에 집중하거나 남은 부분에 집중하는 것 모두 탐닉소비에 영향을 미치지 않았다.

This study investigated the effects of temporal distance of future regulatory behavior, goal progress framing, and self-control on immediate indulgent behavior. The results showed that people with high self-control showed higher indulgence in near future condition versus far future condition when they adopted accumulated(to-date) progress framing. Conversely, when people with high self-control adopted remaining(to-go) progress framing, future regulatory behavior in far future versus near future increased indulgence, but this difference was not statistically significant. In the case of people with low self-control, temporal distance and goal progress framing did not yield any effects on immediate indulgence. The results contribute to the literature on indulgence, temporal distance, and self-control in several ways. First, we have expanded existing researches by finding the moderating factors for the effects of temporal distance of future self-regulatory on indulgence. Second, we have revealed the context in which individuals with high self-control do not hold back indulgence. Third, this study has expanded literature on indulgence by approaching indulgent consumption with the theoretical view of self-regulation, as a dynamic process of managing self-regulatory goal, as well as justification.

Virtual simulation education, which is one of the methods of executing engineering education, is spreading. In general online education, only theoretical learning-centered lessons and practical training of simple small projects are conducted remotely, and it is necessary to disseminate various educational contents. Due to the spread of smart factories these days, most producers use automatic control to produce, inspect and package their products. The operation of automation equipment is controlled by using electricity, and electricity-related learning is operated in various departments. Due to the characteristics of electricity, it is difficult to learn online due to safety issues and high cost of practical equipment. In this paper, we provide a simulation-based electrical control panel distance learning model to improve the sense of accomplishment of education related to electrical training. Through the experiment of the proposed model, it was confirmed that the learning was more satisfied with the virtual simulation education than the online education using the existing equipment. It is expected that it can be used as a basic course for automation equipment education in the future.

본 연구는 리더의 분노통제(anger-control)가 구성원의 체념적 침묵행동(acquiescent silence behavior)에 미치는 직접효과와 이러한 관계에서 권력거리(power-distance)의 조절효과를 규명하고자 하였다. 국내 300인 이상 규모의 기업에 근무하는 직장인을 대상으로 한 설문조사 결과(364부)를 분석하였고, 단일 응답원을 대상으로 한 자기보 고식 설문지법에 의해 발생 가능한 동일방법편의(common method bias)의 문제를 최 소화하고자 사전설문 및 시차를 적용한 본설문을 실시하였다. 연구가설의 검증과 조 건부효과의 심층분석을 위해 부트스트래핑(bootstraping) 방법과 존슨-네이만 방법 (Johnson-Neyman technique)이 적용된 PROCESS macro(2.16.3)를 활용하였다. 가설 검증 결과, 첫째, 리더의 분노통제와 구성원의 체념적 침묵행동 간 직접효과는 유의하 지 않았다. 둘째, 리더의 분노통제와 구성원의 체념적 침묵행동 간의 관계가 구성원의 권력거리 인식 수준에 따라 조절되는 대립효과가 확인되었다. 권력거리의 대립효과를 구체적으로 탐색한 결과 권력거리 인식 수준이 낮은 경우에는 리더의 분노통제가 증 가할수록 구성원의 체념적 침묵행동은 감소하지만, 권력거리 인식 수준이 높은 경우 에는 리더의 분노통제가 증가할수록 구성원의 체념적 침묵행동은 증가하는 것으로 나 타났다. 본 연구는 리더의 분노통제가 조직구성원의 체념적 침묵행동에 미치는 효과 는 권력거리 인식 수준에 따라 상반되게 나타난다는 것을 심층적으로 규명하였다는 점에서 기존 연구를 심화하고 확장하는 의미를 갖는다. 연구 결과를 바탕으로 이론적· 실무적 시사점과 함께 향후 연구 방안을 제시하였다.

The purpose of this study was to investigate the direct effect of a leader’s anger-control on the acquiescent silence behavior of subordinates and the moderating effect of power-distance in this relationship. We analyzed 364 questionnaires collected from employees working in domestic companies in various industries. Dependent variables were measured with a time lag and the pre-questionnaire was tested and reviewed to minimize the common method bias that could be manifested by the self-report questionnaire method. The PROCESS macro (2.16.3) with the bootstrapping method and Johnson-Nayman Technique were used for verifying the hypothesis and in-depth analysis of conditional effects. The results of this study are as follows: First, the direct effect between the leader’s anger-control and the acquiescent silence behavior of subordinates was not confirmed. Second, the moderating effect(confrontation) of power-distance in the relationship between anger-control and acquiescent silence behavior was confirmed. As a result of a detailed probing for the confrontation effects of power distance, In the case of low awareness of power distance, the employees’ acquiescent silence behavior decrease as the leader's anger-control increases. On the contrary to this, if the level of awareness of power distance is high, the employees’ acquiescent silence behavior increase as the leader's anger-control increases. This study takes the meaning of furthering the existing study in that it has been deeply established that the effect of a leader's anger-control on the acquiescent silent behavior of the members of the organization is contrary to the perceived level of power-distance. Based on the results of the study, we proposed theoretical and practical implications and suggestions for future research directions.

군에서는 디젤엔진차량을 주로 운용하고 있다. 고효율, 친환경으로 여겨지던 디젤엔진은 환경·안전 문제로 사회적 이슈가 되고 있다. 이런 디젤엔진의 문제를 고려하여 가격, 경량 화, 소음 측면에서 유리하고 배출되는 환경 오염물질이 적은 가솔린엔진차량을 군에서도 운용할 필요가 있다. 하지만 가솔린엔진은 연료 효율 측면에서 디젤엔진에 비해 좋지 않다. 이런 가솔린엔진의 단점을 극복하기 위해서는 연비를 개선시키는 기술을 적용하여 효과적 인 작전운용 수행을 위한 주행거리를 확보해야 한다. 본 연구에서는 군에서 운용중인 차량 중 가솔린엔진이 적용 가능한 차량을 선정하였다. 가솔린엔진에서 연비에 주요하게 영향을 미치는 흡기저항손실(Pumping Loss)을 줄이는 기술인 가변밸브리프트(Variable Valve Lift) 와 비활성실린더(Cylinder De-activation) 기술을 분석하였다. 이 분석을 바탕으로 더 많은 흡기저항손실을 줄이기 위해 가변밸브리프트와 비활성실린더 기술을 결합한 밸브제어 시스 템과 제어전략을 연구하였다.

Diesel engine vehicle are operated mainly in the military. Diesel engines, considered highly efficient and environmentally friendly, are becoming a social issue due to environmental and safety problem. Considering the problems of diesel engines, the military needs to operate gasoline engine vehicles that are advantageous in terms of price, light weight , noise and have low emissions. However, gasoline engines are not as good as diesel engines in terms of fuel efficiency. In order to overcome the shortcomings of the gasoline engine, fuel efficiency technologies should secure to provide a driving distance for effective operation performance. In this study, we selected a vehicle that can be operated with a gasoline engine in the military. Analysis was done on VVL(Variable Valve Lift) and CDA(Cylinder De-activation) technologies, which are techniques that reduce the pumping loss that significantly affects fuel economy in gasoline engines. To reduce more air pumping loss, a valve control system and control strategy that combined VVL and CDA technologies were studied.

This study examined the effect of the distance Infection Control Education Program (ICEP), developed based on the ADDIE model, on infection control knowledge, attitude, and performance among care workers in long-term care facilities nationwide. The program, developed based on the ADDIE model, was applied to 173 care workers directly responsible for nursing care of elderly residents in lomg-term care facilities. The distance ICEP for care workers was conducted through the website and lasted 30 minutes for each of the eight topics. To determine the effectiveness of the education, infection control knowledge, attitude, performance, and satisfaction were surveyed before and four weeks after the program. Differences in infection control knowledge, attitude, and performance before and after the distance ICEP were assessed by a t-test. A significant difference was observed in knowledge and infection control performance after the distance ICEP was administered to care workers. In the sub-domains of infection control performance, overall understanding of infection, regular infection control education, infection control by special pathogen (multidrug-resistant bacteria, tuberculosis, tick-borne infectious diseases), and detailed infection control education by infection site (pressure ulcers and urinary tract infections) were significantly improved. Infection control knowledge and performance improved through the distance ICEP applied to care workers. Satisfaction also displayed high scores on most items and indicated that it was helpful for infection control in facilities, confirming the effectiveness of infection control education. Based on the survey of care workers nationwide, the infection education program can be effectively used for care workers in the future.

In addition to fixed sensor network such as crop cultivation management system, studies on mobile sensor network have been actively conducting, which is used for collecting information from the moving objects like livestock and cars with use of sensors. The mobility of node enables to prolong the lifespan of network and to manage network efficiently through equal allocation of energy among nodes. To ensure efficient mobility, it is required to make a functional change to MAC layer and routing protocol. In particular, an enhanced transmission mechanism is essential in order to effectively control a link discontinuity or an increase of traffic overhead caused by the mobility of node. This paper aims to propose an energy-efficient transmission mechanism using distance information between sensors in mobile sensor network. Performance of the proposed mechanism has been evaluated by simulation. The simulation results indicate that the proposed mechanism outperforms traditional minimum hop routing method from the perspective of several performance indicators including average packet latency, average energy consumption and network lifespan.

After the release of the film, ‘Avatar’recently, a new paradigm is emerging in the 3D contents industry worldwide due to the expansion of the 3D contents production. Along with the rapid growth of the 3D contents industry, individual nations are stepping up the effort to develop 3D technology and to secure upper hand in the standardization effort in order to secure the leading position in the marketing sphere. As a result, transformation from 2D to 3D is taking place in the diverse industry areas such as TV, S/W, 3D game contents and others as the 3D technology is being used in diverse areas. However, 3D syndromes such as fatigue of the eyes result when 3D image is watched for a long time since the method of using merely the disparity of two eyes is used when watching 3D image to this day. In addition to this problem, there is a systemic level problem, which is the need to maintain specific distance and location in order to feel the 3D effect correctly. Accordingly, this research paper seeks to leverage the change in the 3D image’s Depth level to present 3D Depth level analysis index that will enable users to feel the three-dimensional effect and engagement level most effectively depending on distance and location, and to capitalize the findings to present 3D image control system that can adjust 3D Depth following the three-dimensional effect felt by user.

In this paper, we propose and implement the automated brightness control system using distance measuring sensor for reducing the power consumption of emotional lighting device. In order to reduce the power consumption of emotional lighting devices which express continuous color changes, the proposed device measures the distance continuously using ultrasonic sensor and by using this, it also performs PWM Dimming control. The lighting device is composed of micro controller, LED driver, ultrasonic sensor, communication module and so on. And the device performs the real time brightness control by adapting the measured distance information from ultrasonic sensor to PWM signals. From this experiment, we implement the active lighting system which minimizes unnecessary power consumption during user's absence by adapting existing energy reducing techniques.

The movement theory of control (MTC) predicts that the closest argument is the controller: that is, the MTC cannot be maintained unless the Minimal Distance Principle (MDP) is correct. Accordingly, one of the most important issues in control is whether the MDP is empirically supported. Control shift is a well-known phenomenon that appears to run counter to the MDP. This paper provides supporting evidence in favor of the MDP, showing that control shift follows from the independently motivated principles--the Binarity Principle and the Principle of Co-arguments.

Purpose: In order to keep the acceptable level of the radiation oncology linear accelerators, it is necessary to apply a reliable quality assurance (QA) program. Materials and Methods: The QA protocols, published by authoritative organizations, such as the American Association of Physicists in Medicine (AAPM), determine the quality control (QC) tests which should be performed on the medical linear accelerators and the threshold levels for each test. The purpose of this study is to increase the accuracy and precision of the selected QC tests in order to increase the quality of treatment and also increase the speed of the tests to convince the crowded centers to start a reliable QA program. A new method has been developed for two of the QC tests; optical distance indicator (ODI) QC test as a daily test and gantry angle QC test as a monthly test. This method uses an image processing approach utilizing the snapshots taken by the CCD camera to measure the source to surface distance (SSD) and gantry angle. Results: The new method of ODI QC test has an accuracy of 99.95% with a standard deviation of 0.061 cm and the new method for gantry angle QC has a precision of $0.43^{\circ}$. The automated proposed method which is used for both ODI and gantry angle QC tests, contains highly accurate and precise results which are objective and the human-caused errors have no effect on the results. Conclusion: The results show that they are in the acceptable range for both of the QC tests, according to AAPM task group 142.
