Purpose: This study investigated the effects of respiratory muscle training posture on respiratory muscle activation in stroke patients and presented appropriate posture for the respiratory muscle training. Methods: Thirty-six stroke patients were assigned to either a neutral training posture (n = 13), habitual training posture (n = 12), or side bending training posture (n = 11) group. Respiratory muscle training was conducted using an inspiratory muscle trainer. Each group was asked to adopt either a neutral, habitual, or side-bending posture during respiratory muscle training, which was performed for 30 minutes per day, 10 sets, 3 times per week, for a total of 6 weeks. After each session, external intercostal muscles and sternocleidomastoid muscle activity were measured via surface electromyography. Results: The paretic or non-paretic side intercostal muscle differed significantly in the three groups, and the non-paretic side intercostal muscle was significantly decreased in the neutral training group. The non-paretic side sternocleidomastoid muscle differed significantly in the three groups, and the nonparetic side sternocleidomastoid muscle was significantly increased in the habitual training group. Conclusion: A neutral posture, where appropriate spine and trunk alignment is maintained, is a more effective posture for respiratory muscle training for improving respiratory function in stroke patients.

Purpose: The aim of this study was to investigate the effect of mandible position on proprioception and range of motion (ROM) during neck stabilization exercise using a sling in healthy adults. Methods: The subjects were randomly assigned to either a sling exercise and mandible open group (n=10) or a sling exercise and mandible closed group (n=12). The sling exercise-mandible open group and sling exercise- mandible closed group took part in an exercise program for 30min, three times per week for 4 weeks. After each training session, head repositioning accuracy (HRA) and the ROM of the cervical spine were measured. Wilcoxon’s test was conducted to verify changes within each group, and the Mann–Whitney U test was performed to examine between-group differences. Results: The HRA of the cervical spine was significantly increased during left rotation and extension in the sling exercise-mandible open group. In addition, there were significant differences in both rotations and extension in the two groups. The ROM of the cervical spine increased significantly during both rotations in the sling exercise-mandible closed group. In addition, there was a significant difference in right rotation and extension in both groups. Conclusion: Cervical stabilization exercise using a sling, with the mandible closed increased proprioception and the ROM of the cervical spine.

This study analyzed the effects of smoking on expiratory muscle thickness and pulmonary function in 34 (17 smokers, 17 nonsmokers) healthy female volunteers. The thickness of the internal oblique and transverse abdominal muscles was measured at rest and with forced expiration, using a 7.5-MHz linear ultrasonic imaging probe. The measured thickness was converted into the percentage of change in muscle thickness. All subjects performed maximum expiratory flow maneuvers using a spirometer to determine the forced vital capacity, forced expiratory volume in the first second, peak expiratory flow, and forced expiratory volume in 1 s as a percentage of forced vital capacity. There were significant differences in pulmonary function (forced expiratory volume in 1 s as a percentage of forced vital capacity, peak expiratory flow) between the smokers and nonsmokers,as well as significant differences in expiratory muscle thickness (transverse abdominal). This study showed that female smokers have impaired pulmonary function and expiratory muscle contraction.

Purpose: The purpose of this study was to examine the effects of the PNF stabilization technique for the hip joint and the bridging exercise on the trunk stabilizer muscles in healthy adults. Methods: Twenty-eight healthy adults were randomly allocated to either a PNF stabilization exercise group (n = 12) or a bridging exercise group (n = 16). The outcome measures included the contraction thickness ratio in the transversus abdominis (TrA), internal oblique (IO), and external oblique (EO), and the TrA lateral slide was assessed during the abdominal drawing-in maneuver using b-mode ultrasound. The researcher measured the abdominal muscle thickness of each participant before the therapist began the intervention and at the moment that the intervention was applied. Between-group comparisons were performed using the Mann– Whitney U test. The level of statistical significance was set at 0.05. Results: The PNF intervention program showed a significant increase in the trunk stabilizer muscle. The percentage of change in the TrA thickness showed a significant interaction between intervention. However, there were no significant differences in the IO and EO between the two groups. Conclusion: The PNF stabilization technique for the hip joint can be used effectively to improve the IO and TrA muscles in healthy adults.

Designers consider cultures in design process, because customer’s design taste is influenced by local cultures. Moreover, an expanding internalization can enhance the value of local culture as it reduces the fear of vanishing local identity. The goal of this study is to suggest a classification table of design modeling elements in cultural types. In the literature research, I studied cultural dimensions and modeling elements. Cultural dimensions are organized by five dimensions through each culture theory from Geerf Hofstede which includes PDI, IDV, MAS, UAI, LTO dimensions. Through each modeling theory from five experts, modeling elements are organized by three elements including material, color and form. Each element has opposite sides. With two fixed models I designed an experimental module. As a result, a classification table was produced from the compiled statistics, and ‘Culture dimensions - Modeling elements’ table was completed. Main purpose of this study is to suggest a classification table of modeling elements in cultural types by integrating experts’ opinions. This table presents a design methodology for designers.

소아기의 과체중 혹은 비만은 성인기의 만성질환의 onset 위험을 증가시키는 대사이상을 야기하므로 관련된 obesogenic 환경 (나트륨 섭취 등)을 제어할 필요가 있다. 본 연구에서는 소아기의 과도한 소금섭취가 신장의 재흡수 기능을 조절하는 SLC12A3기능장애로 이어져 고혈압 및 비만을 야기하는지를 확인하고자 하였다. 서울 구로구에 소재한 8~9세 초등학생 752명 (남학생: 379명 여학생: 373명)을 대상으로 BMI가 85 percentiles이상을 비만군으로, 이하를 정상군으로 분류하였다. SLC12A3 rs11643718 유전자형은 GG (wild)와 GA + AA로 분류하여 신체계측, 혈액검사, 식이조사 등을 비교분석하였다 대상자의 남아가 여아보다, 비만군이 정상군보다 신체지수, 혈액지수, 식사섭취량이 여아보다 높았다. 남녀 모두 비만군에서 높은 TG와 낮은 HDLc를 보여주었지만 비만한 남아는 혈압에, 비만한 여아는 인슐린저항성에 더 민감한 반응을 보였다. 비록 남녀차이는 있지만 비만군 및 정상군 모두에서 SLC12A3의 GA + AA형이 GG형보다 혈압과 체중이 높았다. GG 유전자형을 가지고 있는 소아는 혈중 LDLc, FBS, insulin등이 높거나 식이 콜레스테롤섭취가 증가할수록 비만이 될 위험도가 증가하였고 엽산의 섭취가 증가할수록 비만위험도는 감소하였다. 반면, GA + AA 유전자형을 가지고 있는 소아는 고나트륨 (> 4,000 mg/day)섭취시 비만위험도 (odd ratio)가 15.57배 증가하였고 남아 (22.84배)에서 더욱 위험도가 높았다. HDLc의 경우는 유전자형에 관계없이 증가할수록 비만위험도가 감소하였다. 결론적으로 SLC12A3 (rs11643718) 유전자의 A allele를 가진 형이 나트륨에 특이적으로 반응하여 과체중위험을 증가시키는 것으로 생각된다.
Purpose: Obesogenic environments in children, in particular excessive intake of sodium, generate hypertension, which is a major risk factor for chronic diseases. Methods: In all, 725 children, 379 boys and 373 girls, aged 8~9 years were recruited from seven elementary schools in Kuro-ku, Seoul. To evaluate whether or not obesity risk was modulated by salt-sensitive genes, Solute Carrier Familiy 12 member 3 (SLC12A3) was used as the target. After children were assigned into obese (BMI > 85 percentile) or non-obese groups, anthropometry, blood biochemistry, and dietary intakes were measured according to the genotypes GG (wild) or GA+AA (hetero+mutant). Results: Without gender differences, high TG and low HDLc were detected in the obese group compared to the non-obese group. Regardless of obesity, weight gain and blood pressure (BP) increased in the SLC12A3 GA+AA genotype rather than in the GG type. HDLc was associated with obesity risk without genotype difference. Odd ratios for risk of obesity were 15.57 (95% CI 2.192~110.654), 22.84 (95% CI 1.565~333.469), and 9.32 (95%CI 1.262~68.817) in boys and girls with GA+AA genotypes as sodium intake increased above 4,000 mg/day. Dietary calcium, sodium, folate, and vit C were associated with obesity risk according to gender or genotype differences. Since high folate intake reduced obesity risk in only boys with GG type. Risk for overweight and obesity increased in boys with GA+AA genotypes and dietary habits with high sodium and cholesterol and low folate. Conclusion: The A allele of SLC12A3 rs11643718 was sensitive to development of obesity in children as sodium intake increased.

We have studied the effects of Ag on the characteristics of $Sn_{43}Bi_{57}Ag_x$(wt%) lead-free solders for photovoltaic ribbon. Ag atoms in the solder formed an alloy phase of Ag3Sn after reacting with some part of Sn atoms, while they did not react with Bi atoms, but decreased the mean size of Bi solid phase and the thickness of solder. When Ag atoms of 3.0 wt% was added to eutectic $Sn_{43}Bi_{57}$(wt%) solder, it showed the optimally useful results that the peel strength of photovoltaic ribbon greatly increased and the sheet resistance of the solder decreased. In the meanwhile, the eutectic $Sn_{43}Bi_{57}$(wt%) solder showed a low melting temperature of $138.9^{\circ}C$, and showed a very similar result regardless of the added amount of Ag atoms.

목 적: 폐쇄성무호흡증(Obstructive sleep apnea, OSA)과 단순코골이(simple snoring) 환자들의 성격적 특성에 대한 연구가 부족한 실정으로, 본 연구에서는 아이젱크 성격검사(Eysenck Personality Questionnaire, EPQ)를 사용하여 OSA와 단순코골이 환자들의 성격적 특성과 차이를 연구하였다. 방 법: OSA나 단순코골이가 의심되는 237명의 피험자들이 연구에 포함되었다. 모든 피험자들은 EPQ 등의 설문 검사를 받았고, 수면다원검사실에서 야간수면다원검사를 시행하였다. 무호흡저호흡지수(Apnea-Hypopnea Index, AHI) 5 이상은 OSA, 5 미만은 단순코골이로 분류되었다. 결 과: OSA군은 단순코골이군에 비해 정신병적 경향성(Psychoticism)에서 유의하게 낮은 점수를 보였다(F=4.563, p=0.034). 기타 외향성-내향성(Extraversion, F=3.029, p=0.083), 허위성(Lie, F=0.398, p=0.529), 신경증적 경향성(Neuroticism, F=3.367, p=0.068)에서는 OSA군과 단순코골이 군간에 유의한 차이가 없었다. OSA군 내에서 시행한 상관분석결과 AHI가 높을수록 외향성(r=0.16, p=0.029)이 높았고, 허위성(r=-0.31, p<0.001)이 낮았다. OSA군에서 EPQ의 네 가지 척도를 종속변인으로 설정한 다중회귀분석 결과, 허위성은 나이가 많고(B=0.14, p<0.001), AHI가 낮을수록(B=-0.05, p<0.001) 증가하였다. 정신병적 경향성은 피츠버그 수면질 설문(Pittsburgh Sleep Quality Index, PSQI)이 높을수록(B=0.14, p<0.001), 신경증적 경향성은 PSQI가 높고(B=0.34, p=0.001), 여성인 경우(B=3.15, p=0.003) 증가하였다. 외향성은 나이가 적고(B=-0.08, p=0.020), 체질량지수(body mass index)가 높을수록(B=0.26, p=0.023) 증가하였다. 결 론: 본 연구 결과는 OSA 환자들이 단순코골이 환자들에 비해 유의하게 정신병적 경향성이 낮음을 보여주었다. OSA군 내에서는 AHI가 높을수록, 허위성이 낮고 외향성이 높은 경향을 보였다.
Objective: Few studies have evaluated the personality characteristics of patients with obstructive sleep apnea (OSA) and simple snoring. We investigated the personality characteristics of OSA and simple snoring patients and compared differences in personality between the two groups using the Eysenck Personality Questionnaire (EPQ). Materials and Methods: Two hundred and thirty-seven patients who were suspected to have OSA or simple snoring participated in this study. A self-questionnaire which included the EPQ was administered to all participants. All subjects underwent polysomnography in a sleep laboratory and those with an apnea-hypopnea index (AHI) ${\geq}5$ were included in the OSA group, while those with an AHI <5 were included in the simple snoring group. Results: OSA patients had significantly lower scores for Psychoticism (F=4.563, p=0.034) than simple snorers. There were no significant differences in Extraversion (F=3.029, p=0.083), Lie (F=0.398, p=0.529), or Neuroticism (F=3.367, p=0.068) scores between the two groups. In the correlation analysis of the OSA group, AHI was positively correlated with Extraversion score (r= 0.16, p=0.029) and negatively correlated with Lie score (B=-0.31, p<0.001). Using multiple stepwise linear regression analysis with the four EPQ parameter scores as dependent variables, Lie score was associated with older age (B=0.14, p<0.001) and lower AHI (B=-0.05, p<0.001), Psychoticism score was associated with higher Pittsburgh Sleep Quality Index (PSQI ; B=0.14, p<0.001), Neuroticism score was associated with higher PSQI (B=0.34, p=0.001) and female sex (B=3.15, p=0.003), and Extraversion score was associated with younger age (B=-0.08, p=0.020) and higher body mass index (B=0.26, p=0.023). Conclusion: This study suggests that patients with OSA are significantly less prone to psychotic personality characteristics than those with simple snoring. Among OSA patients, higher AHI was correlated with low falsehood and high extraversion tendencies.

두 마리의 개가 각각 다른 임상 증상, 저혈당증과 변비를 주증으로 내원하였다. 복부 방사선 검사에서 연조직 밀도의 크고 둥근 종괴가 하복부에서 관찰되었다. 변비를 주증으로 하는 개에서는 이 종괴로 인한 결장의 직경 감소가 관찰되었다. 복부 초음파 검사에서 이질적 에코의 크고 둥근 종괴가 한계 명료하게 관찰되며, 복강의 주요 장기와 관련이 없을 것으로 생각되었다. 탐색적 개복술에서 종괴는 결장의 장막층에서 유래한 것으로 확인되었고, 쉽게 제거되었다. 조직검사에서 평활근종으로 확인되었고, 두 마리 모두 재발 및 후유증 없이 임상 증상이 개선되었다. 결장 평활근종의 신생물딸림증후군으로 저혈당증이 발생한 증례와 결장 평활근종의 직접적인 압박으로 인한 변비가 발생한 증례를 보고한다.
Two dogs were referred with the clinical signs of depression and constipation, respectively. One dog with depression had hypoglycemia on biochemistry. On survey abdominal radiographs, a soft tissue density round mass with calcified spots was identified cranial to the urinary bladder. On ultrasonographs, a solitary oval heterogeneous complex-echoic mass with well-defined margin was found. On surgery, the mass was pedunculated and originated from the colonic wall. The resected mass was confirmed as colonic leiomyoma. The other dog with constipation had normal CBC and biochemistry values. On survey abdominal radiographs, there was a soft tissue density round mass dorsal to the descending colon and rectum. The descending colon was displaced ventrally and narrowed by the mass. On ultrasonographs, a well-defined round heteroechoic mass compressed the colon. The mass was also pedunculated and originated from the colonic wall on surgery and confirmed as colonic leiomyoma. Two dogs recovered without any clinical signs after surgery and showed permanent resolution of the clinical signs, respectively.

복강 내 종괴 촉진 및 구토, 식욕부진, 발열, 체중 감소, 수면시간 증가를 보이는 한 마리의 고양이가 서울대학교 부속 동물병원에 내원하였다. 신체검사, 혈액검사와 더불어 영상학적 검사가 진행되었다. 복부 초음파, CT 검사를 통해 소장분절과 연결된 종괴가 확인되었으며, 종괴에 대한 세포학적 검사 결과 소화기 림프종으로 잠정 진단되었으며 이에 따른 항암치료가 이뤄졌다. 항암치료가 진행되는 동안 증상은 호전되지 않았고, 결국 항암치료 중단 6일 후 폐사하였다. 부검이 이뤄졌으며 최종적으로 병변은 조직병리학적 검사를 통해 고양이 전염성 복막염으로 확진하였다.
A 2-year-old, intact male, Persian exotic cat, weighing 2 kg with a history of a palpated abdominal mass was admitted to Veterinary Medical Teaching Hospital, Seoul National University. On routine complete blood count (CBC) and serum biochemical analyses, there were anemia and 0.45 of albumin to globulin ratio. A feline infectious peritonitis (FIP) virus antibody test kit was negative. Radiography, ultrasonography and computed tomography (CT) were performed. A markedly enlarged abdominal mass was found. On cytologic examination of this mass, it was diagnosed as alimentary lymphoma or pyogranulomatous inflammation. Chemotherapeutic treatment for intestinal lymphoma was provided for several weeks, but the mass size was increased and clinical signs were not improved. The cat died six days after discontinuing chemotherapy. On postmortem examination, the definitive diagnosis was FIP. This case describes a cat with FIP in which an abdominal tumor had been suspected clinically.
