The e-Government standard framework provides overall technologies such as reuse of common components for web environment development such as domestic government/public institutions, connection of standard modules, and resolution of dependencies. However, in a standardized development environment, there is a possibility of updating old versions according to core versions and leakage of personal and confidential information due to hacking or computer viruses. This study directly analyzes security vulnerabilities focusing on websites that operate eGovFrame in Korea. As a result of analyzing/classifying vulnerabilities at the internal programming language source code level, five items associated with representative security vulnerabilities could be extracted again. As a countermeasure against this, the security settings and functions through the 2 steps (1st and 2nd steps) and security policy will be explained. This study aims to improve the security function of the e-government framework and contribute to the vitalization of the service.

The purpose of this study is to examine the relationship between the Junk Art characteristics of Viktor&Rolf’s fashion collections and the Aesthetics of Ugliness, and identify their connection and significance in fashion. First, the study identifies the definition and aesthetic value of ugliness by examining Karl Rosenkranz’s theory of ‘The Aesthetics of Ugliness’, and categorizes its appearance in fashion by organizing preceding research analysis papers. Second, the definitions and characteristics of Junk Art, and its distinct features applied in fashion were considered. Third, after reviewing Viktor&Rolf’s design philosophy, the Junk Art properties of the selected collections’ representative looks were analyzed via Greimas’ Semiotic Square. Lastly, each collection was classified based on the previously organized ‘aesthetics of ugliness in fashion’ in order to inspect the relationship between Junk Art and ugliness. A selection of 5 Viktor&Rolf’s Haute Couture collections ranging from Spring 2015 to Spring 2020 were analyzed, utilizing both research analysis through preceding research papers, fashion magazines, photographies, Viktor&Rolf’s official website, and case analysis through Greimas’ Semiotic Square. The ugliness of Junk Art infracts the general rules of beauty by suggesting the underlying creativity in fortuity and variation and highlights the importance of harmony and sensibility. By using junk as its material, the border between the ordinary and the deviant area of art had been dismantled, eventually bringing about the value of the insignificant and expressing its vitality and free will.

본 논문은 웹 애플리케이션의 증가로 인해 소프트웨어 내 보안 취약점을 이용한 사이버 공격이 증가하고 있다. CSRF(Cros s-Site Request Forgery) 공격은 특히 웹 사용자와 개발자에게 심각한 위협으로, 사전에 예방해야하는 공격이다. CSRF는 사용 자의 동의 없이 비정상적인 요청을 통해 공격을 수행하는 기법으로, 이러한 공격으로부터 웹 애플리케이션을 보호하기 위한 방법은 매우 중요하다. 본 논문에서는 Spring Security와 Apache Shiro 두 프레임워크를 통해 CSRF 방어에 대한 성능을 비교 분석하고 검증하여, 효과적으로 적용 가능한 프레임워크를 제안한다. 실험 결과, 두 프레임워크 모두 CSRF 공격 방어에 성공 하였으나, Spring Security는 평균 2.55초로 Apache Shiro의 5.1초보다 더 빠르게 요청을 처리하였다. 이러한 성능 차이는 내부 처리 방식과 최적화 수준의 차이에서 비롯되었으며, 시스템 자원 사용 측면에서는 두 프레임워크 간에 차이가 없었다. 따라서 높은 성능과 효율적인 요청 처리가 요구되는 환경에서는 Spring Security가 더 적합하며, Apache Shiro는 개선이 필요하다. 이 결과는 웹 애플리케이션의 보안 아키텍처 설계 시 중요한 참고 자료로 활용되기를 기대한다.

This paper addresses the increasing cyber attacks exploiting security vulnerabilities in software due to the rise in web a pplications. CSRF (Cross-Site Request Forgery) attacks pose a serious threat to web users and developers and must be pr evented in advance. CSRF involves performing malicious requests without the user's consent, making protection methods c rucial for web applications. This study compares and verifies the CSRF defense performance of two frameworks, Spring Se curity and Apache Shiro, to propose an effectively applicable framework. The results show that both frameworks successfu lly defend against CSRF attacks; however, Spring Security processes requests faster, averaging 2.55 seconds compared to Apache Shiro's 5.1 seconds. This performance difference stems from variations in internal processing methods and optimiza tion levels. Both frameworks showed no significant differences in resource usage. Therefore, Spring Security is more suita ble for environments requiring high performance and efficient request processing, while Apache Shiro needs improvement. These findings are expected to serve as valuable references for designing web application security architectures

Purpose: The purpose of this study was to impact of force system change in finger spring that add helical coil one round on orthodontic force. Methods: The following conclusions were drawn from the experiment conducted after bending 90 samples with a CNC wire forming machine while changing the height and lumen size to 1 - 3 - 5 and 2 - 3 - 4 respectively in the coil of the force system in finger spring added with one wheel of helical coil of 18-8 stainless steel round wire (Φ0.5 , spring hard) from Jinsung Co. in domestic market under the following conditions: Laboratory name = Instron 5942; Temperature(deg ) = 18.00; Humidity(%) = 50.00; Rate 1 = 10.00000 /min; Compressive extension = 5.0 . Results: When Coil height is 1, 3, 5 and lumen size is 2, 3, 4 reduce finger spring as mean value of compressive extension occasion maximum load(mN) increases as coil height rises, and lumen size grows to 5.0 . And was expose that compressive load(mN) increases as coil position of finger spring rises and increase as lumen size is decrescent. Conclusion: As the adherence height of coil was raised from 1mm through 3 to 5 , compressive load increased. As the lumen size increased from 2 through 3 to 4 , compressive load decreased. Therefore, these results suggest that it is desirable to lower the coil height and enlarge the lumen size to enhance the biomechanical efficiency of finger spring when manufacturing the finger spring for removable orthodontic devices

In this study, a layout was designed to adjust the location of the LPG fuel tank by combining a Z-Spring and an Airbag in an LPG 1-ton truck air suspension assembly, and a structural analysis based on the finite element method was performed considering the load conditions of extreme situations based on the weight taken into account. The study was performed under a total load condition of 2.1 tons per axle with a safety factor of 2, and it was confirmed that the maximum stress value occurring in each part is within the yield strength value of the material. Through these results, it was confirmed that the designed LPG 1-ton truck air suspension assembly is a system with secured structural stability.

In this paper we consider the localization of a sensor network where the nodes are heterogeneous, in that some of them are able to measure the distance from their neighbors, while some others are just able to detect their presence, and we provide a post-processing algorithm that can be used to improve an initial estimate for the location of the nodes, based on a mass?spring optimization approach, taking into account presence and distance information, as well as one-hop and two-hop information.

This study focuses on the cultural and social context of A Dream Journey to Peach Blossom Spring (Mongyu towŏn to 夢遊桃源圖) the only extant work by An Kyŏn 安堅, the best-known painter of early Chosŏn, to show the manner of its production and function. The painting was a pictorial addition to the sich’uk 詩軸, a mounted scroll of poems, created to praise Prince Anp’yŏng (安平大君) and interpret the significance of his dream in which he visited Peach Blossom Spring, a legendary place invented by the Chinese poet Tao Qian 陶潛. The prince presented a dream record, an accepted literary form at a time when there was a general belief in the prophetic meaning of dreams, and required twenty-one celebrated writers to compose eulogistic poems to accompany the painting, which served as a visual description of his dream. The poets wrote in such a way as to allow the viewer to repeatedly imagine the Peach Blossom Spring. As such, the painting functioned as visual inspiration for the twenty-one writers and became an ornament for their poems. By revealing the process of making the sich’uk and the effect of the dream record, this study re-evaluates the content, style, and composition of A Dream Journey to Peach Blossom Spring.

Wounds are common prevalent clinical problem found in day to day life. Although numerous studies have been conducted in this field but only few studies address about the mineral effect on wound healing process. To explore the therapeutic effect of the high mineral spring water (HMW) on the wound healing process, we carried out an animal injury model for that female SKH-1 mice were divided into five groups: normal control (NC, n=10), untreated control (NT, n=10), 100 % Pure HMW (PHMW, n=10) group, 10% HMW experimental (DHMW, n=10) and two round wounds (approximately 5 mm in diameter) total of 6 round wounds were punched into each side of the superior region of the posterior extremity by biopsy puncher to each mouse. We found that HMW spraying led to an enhanced healing speed compared to untreated control group. Reactive oxygen species was suppressed in both PHMW and DHMW group compared to NT group. Collectively, our results provide the evidence that HMW might be beneficial for the treatment of skin wound injury.

H∞ 제어와 뮤-합성 제어 방법을 사용하여 두 가지 상황, 즉 불확실성이 포함되지 않았을 때와 20% 불확실성이 포함되었을 때, 하에서 스프링-매스-댐퍼 시스템의 진동을 최소화하였다. 두 컨트롤러의 안정성 및 성 능 파악을 위해 GM와 PM 값을 사용하여 분석되었다. 중앙 수치 미분법과 RMS 방법을 사용하여 출력 응답의 신호 강도가 비교되었다. 끝으로, 안정성 비교를 위하여 3가지 다른 Wperf1 가중함수의 경우에 대해 총 40개의 H∞ 제어기와 뮤-합성 제어기 무작위 표본이 생성되었다. 전반적으로, 40개 플랜트 모델에서 얻어진 결과 값의 견고한 안정성과 성능 값에 따르면, 뮤-합성 제어기가 H∞ 제어기보다 진동 관리에 효과적임이 입증되었다

With a given spring-mass-damper system, ∞ and -synthesis control methods are used to build system controllers which minimize vibrations at two major natural frequencies in two cases; without uncertainty; with 20% uncertainty. In order to check the stability and performance of two controllers, those are examined using GM and PM values. The signal strength of output responses is compared using the concept of central numerical differentiation and then results are quantified using the RMS method. Lastly, 40 random samples of H∞ and μ–synthesis controllers are obtained for three different Wperf1 weighting functions and drawn in the time domain in order to compare the stability. Overall, μ-synthesis controller manages the vibrations much better than H∞ controller according to the robust stability and performance values obtained by simulating random samples of 40 plant models.

Atopic dermatitis (AD) is a chronic relapsing allergic inflammatory skin disease that currently affects millions of children and adults worldwide. Drugs used to treat these inflammatory diseases include anti-histamines, corticosteroids and calcineurin inhibitors but these drugs have their limitations such as adverse effects with their long-term usage. Thus, researcher’s interest in several alternative and complementary therapies are continually growing and balneotherapy is one of these approaches. Therefore, we investigate the bathing effect of high concentration mineral spring water (HMW) on redox balance and immune modulation in 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis like inflammation in hairless mice. We induced AD-like inflammation by application of DNCB on the dorsal skin of female skh-1 hairless mice. The mice were treated with 100% pure HMW (PHMW) and 10% diluted HMW (DHMW) through bathing once a day for 4 weeks. Tacrolimus ointment (0.1%) was used as positive control (PC) and only DNCB treatment as negative control (NeC) group. The severity of skin lesion inflammation was assessed through clinical scoring and observing scratching behavior. Levels of immunoglobulin E (IgE) and inflammatory cytokines in serum were detected by ELISA and multiplex bead array system, and the levels of oxidative stress-related biomarkers and antioxidant enzyme were also measured. We found that HMW significantly decreased the scratching behavior in PHMW and DHMW groups at the 2nd week and in PHMW group at 4th week compared to NeC group. Likewise, serum IgE level was significantly decreased in DHMW group as compared to NeC group. In line, the level of inflammatory cytokines in serum such as interleukin (IL)-1 , IL-13 and tumor necrosis factor- β α were significantly inhibited in PHMW and DHMW groups compared to NeC group. In parallel, total reactive oxygen species (ROS) of serum level was significantly decreased in PHMW treatment groups compared to NeC group. Consistently, serum malondialdehyde (MDA) level in PHMW group was lower than in NeC group. By contrast, glutathione peroxidase (GPx) activity was significantly enhanced in PHMW than NeC. Collectively, our study indicates a balneotherapeutic effect of HMW on DNCB-induced AD like inflammation in hairless mice via immunomodulation and redox balance.
