This study was carried out to investigate the effect of chromium picolinate supplementation on the metabolism of rats. Male Sprague-Dawley rats were divided into 3 groups and each group had 16 rats. Three experimental diets of CT(control), HS(high sucrose) and HF(high fat) were fed for 10 weeks and then chromium picolinate were supplemented to HS and HF groups for 6 weeks. Eight rats from each group were sacrificed after 10 weeks and another 8 rats from each group were sacrificed after 16 weeks. The results from this experiment were summarized as follows: The change of calorie intake and body weight was not significantly different among three groups after chromium picolinate supplementation. The plasma glucose and insulin concentration in CT group tended to increase after 16 weeks but those in HS and HF groups tended to decrease after chromium picolinate supplementation. The plasma triglyceride and cholesterol concentration of CT group tended to be higher than those of HS and HF groups which were supplemented by chromium picolinate. Our results indicate that chromium picolinate tend to reduce blood glucose, insulin, triglyceride, and cholesterol level but increase HDL-cholesterol level.

The aim of this work was to investigate the physiological activities of capsaicin-resistant bacterium, Leuconostoc mesenteroides GK-10 isolated from fully fermented mustard leaf kimchi. Initially, the morphological, physiological and biochemical characteristics of strain GK-10 were examined. Based on phylogenetic analysis using 16S rRNA sequencing, the isolate was identified as L. mesenteroides GK-10 and phylogenetic tree of the strain was plotted. L. mesenteroides GK-10 grew well in the different concentrations of capsaicin (0-600 μg/mL). Various physiological activities (e.g., tyrosinase inhibitory activity, ACE inhibitory activity, antioxidant activity, SOD-like activity, depletion of sodium nitrite) of L. mesenteroides GK-10 cultures with different concentrations of capsaicin were evaluated and compared to the cultures of L. mesenteroides DK-3 as a standard strain. According to the results, all of the physiological activities evaluated in this work were considerably higher in L. mesenteroides GK-10 cultures with 600 μg/mL capsaicin compared to L. mesenteroides DK-3 cultures with the same capsaicin concentration, although the physiological activities of GK-10 were higher or lower compared to those of DK-3 in the absence of capsaicin. In consequence, this work showed that L. mesenteroides GK-10 strains can maintain their physiological activities despite the presence of high concentrations of capsaicin.

원화환율의 장기구매력평가에 관한 실증분석 : 부호검정법 Sign Unit Root Test

吳有珍,朴炳旭 한국국제경제학회 2004 국제경제연구 Vol.10 No.2

구매력평가관계의 성립의 여부는 국제금융이론에서 중요한 관심대상 중의 하나이다. 대표적인 실증분석 방법으로는 Dickey-Fuller류의 단위근 검정법을 사용해서 실질환율을 분석하는 것이다. 이런 검정법들은 낮은 검정력(power)과 최소자승법(Least squares method)에 기반하기 때문에 이상치(outlier)에 민감하다는 단점을 가지고 있다. 본 연구에서는 이런 단점을 보완하기 위하여 새로운 부호검정법(sign test)을 도입하였다. 부호검정법은 이상치와 정규가정을 만족하지 않는 자료의 경우에도 사용가능하도록 조건을 완화하여 낮은 검정력(power)을 향상시킨다. 본고에서는 미국, 영국, 독일, 캐나다, 그리고 일본 등 우리나라 주요 교역국들의 실증자료로 부호검정법과 기존의 Dickey-Fuller 검정의 결과를 비교분석 하였다. 분석기간은 외환위기 이후까지 포함한 전체 기간과 외환위기 이전까지의 기간으로 나누어서 검정을 시도하였으며, 분석결과 한국은 어느 국가와도 구매력평가관계가 성립되지 않았다. Purchasing power parity(PPP) is of interest in international finance literatures. The most popular method for testing PPP is the Dickey-Fuller(DF) test based on the ordinary least squares estimator(OLSE). The OLSE-based unit root tests, however, suffer from size distortion and power loss. We use a new sign unit root test which has simple exact null distribution and is robust to possible outliers from heavy-tailed errors. We also investigate whether PPP holds between Korea won and other currencies of important trade countries such as United States, the United Kingdom, Germany, Canada, and Japan by testing for unit roots in real exchange rates. We use Korean won as the base currency.

A correlation analysis was made to understand the interaction between the growth patterns of some craniofacial skeletal components and occlusal plane inclination. 5 angular measurements(S.a. Ar.a, Go.a, UGo.a, LGo.a), 6 linear measurements(ACBL, PCBL, RH. MBL. AFH. PFH) and OP/SN. obtained from 83 cephalometric tracing records, were selected and the relationship between the occlusal plane angle and those measurements were analyzed statistically. Ramus Height(r=-0.55), Posterior Facial Height(r=-0.41), were found to be negatively related with Occlusal Plane angle, while Lower Gonial angle(r= 0.35), Saddle angle(r= 0.24) were found to be positively related with Occlusal Plane angle(p(0.05). The results obtained from the above analysis were further assessed with stepwise regression analysis, using Occlusal Plane angle as a dependant variable, and RH, LGo.a and S.a as explanatory variables. Stepwise regression analysis revealed that all the explanatory variables were found to be significant.(p<0.05) [OP/SN] = -8.74-0.33(RH)+0.23(S.a)+0.20(LGo.a). (R²=0.44). This stepwise regression analysis explains, to some extent, the relationship between the growth patterns of some craniofacial skeletal components and the occlusal plane inclination. 1. The inclination of Occlusal Plane angle is noticeably related with the growth patterns of some craniofacial skeletal components, i.e. RH, PFH, Saddle angle and Lower Gonial angle 2. In high Occlusal Plane angle, the Ram us Height tends to be shorter, and the Saddle angle and Lower Gonial angle tend to be obtuse.

김유진,오계헌 순천향대학교 기초과학연구소 2021 순천향자연과학연구 논문집 Vol.27 No.1.2

Soil samples were collected from explosive manufacturing plant sites and used for enrichment of microbial consortia with HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazocane) under aerobic and nitrogen-limiting conditions. Among five isolates from microbial consortia using HMX as substrate for growth, an isolate HK-5 which has good HMX degradability was selected for this work. Both BIOLOG system and 16S rRNA sequencing were conducted to identify the strain, which was assigned to Pseudomonas plecoglossida HK-5. Complete degradation of 75 µM HMX was achieved after 50 days of incubation. Analysis of SDS-PAGE and Western blot revealed that stress shock proteins, DnaK and GroEL, specifically reacting with anti-DnaK and anti-GroEL monoclonal antibodies were produced when cells were treated with HMX. Scanning electron microscopic analysis demonstrated the presence of cells with wrinkled surfaces containing perforations and irregular rod-shaped forms after exposure to HMX.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

여성복식에 표현된 가슴의 패션 정체성 : 19세기 한국 · 프랑스를 중심으로 Focusing on Korea and France in the 19th Century

오유진,최현숙 동덕여자대학교 디자인연구소 2004 디자인포럼21 Vol.7 No.-

본 연구는 패션 정체성 이론에 근거하여 패션의 정체성을 보다 확실히 이해하고, 나아가 이를 디자인 발상의 연구 기초 자료로 활용할 수 있음을 증명하고자 하는데 그 목적이 있다. 패션 정체성을 설명하는 구체적인 사례 제시를 위해 19세기로 연구 시대 범위를 한정했다. 또한 보다 구체적인 연구를 위해 연구대상을 한국과 프랑스로 선정했다. 이러한 연구 범위 안에서 문헌 및 실증 자료들을 통해 패션과 문화의 상관성을 바탕으로 한국과 프랑스의 패션 정체성을 비교 연구한다. 특히, 여성의 가슴에 관한 두 나라의 인식의 차이가 어떻게 패션 디자인에 다르게 표현되었는지 파악하고 이를 바탕으로 보다 발전적인 디자인 발상을 통한 패션계의 발전을 도모하는데 연구의 의의를 두었다. 한국과 프랑스의 가슴의 패션 정체성을 비교해본 결과, 양국 모두 모성성, 관능성, 패션성이 공존했다. 단 이러한 가슴의 패션 정체성의 표현 방법에 있어서 차이를 보였다. 19C 한국과 프랑스 여성복식에 표현된 가슴의 패션 정체성은 '은폐/노출'이라는 양면성을 갖고 복식안에서 보다 구체적으로 표현된다. 전체적으로 살펴볼 때, 양국 모두 가슴의 각 정체성 성격 마다 위에서 언급한 세 가지 정체성 성향이 모두 나타났다. 그리고 '은폐/노출'이라는 양면적 성향에 있어서는 관능성에 있어서 대조적인 차이를 보이고 모성성에 있어서는 동일한 성향을 띠고 있다. 또한 패션성에 있어서는 프랑스는 은폐와 노출이 모두 나타난데 반해 한국은 은폐적 성향을 띠고 있다. 이것은 양국간의 가슴에 대한 인식의 차이에서 비롯된 것이라 할 수 있는데 이러한 인식의 차이는 곧 문화적 차이를 의미하는 것이다. 연구의 결과 패션과 문화사이의 밀접한 상호 관련성을 재확인할 수 있었으며, 특히 여성 패션에서 가슴의 패션 정체성과 복식문화의 상관성을 찾아 볼 수 있었다. 각기 다른 문화권이나 시대는 각각 고유한 패션 정체성을 갖는데, 이러한 상호 독립적이면서 상이한 패션의 상대성에 대한 존중은 넓은 시각에서 패션을 이해할 수 있게 하며 새로운 패션을 창출하는 원동력이 된다. The women's dress style in the 19th century in Korea and France is influenced by diffrent socio-cultural trend. The two fashion trends in Korea and France build diffrent fashion identity based on their cultural influences. It causes diffrent perceptions and expressions of the dress styles to women's breasts in the oriental and western society until now. The purpose of this study was to understand the fashion identity more clearly based on the theorem of the fashion identity, also to prove the availability of using it as the groundwork for studying the design concept. This thesis focused on the 19th century to suggest a concrete example to explain the fashion identity. In addition, Korea and France are selected for the same reason. Korea and France fashion identity is compared each other in this study through various literature and actual proof based on the corelationship between the fashion and the culture. Especially, the diffrence of cognition of the breasts between the two countries is studied in order to investigate how it is expressed in the fashion design and to search the way of development of fashion world is seek for through more developing design concept on the basis of it. As the result of the fashion identity study about the breasts in Korea and France, the nature of motherhood, sexuality, and fashion was shown for two countries. Yet, the way the breasts fashion identity was expressed was different in two countries. This differentiation comes from the recognition of the breasts in the two countries, which means different culture of them. In other words, fashion and culture have a close relationship, and the corelationship between the breasts fashion identity and dress culture could be expected. In addition, different culture and time period different characteristics of fashion identity. Those are independent and relative to each other at the same time. This is helpful in understanding fashion the role and meaning of it through the comparison analysis of the breasts fashion identity expressed in women's dress style in the 19th century in Korea and France. Also, it suggested the foregoing way of the future fashion identity of the present dress design through the comparison of old dress style. The fashion identity plays an important role in taking the new fashion and approving a culture relativity in accordance to the global trend of the present fashion. The fashion identity forms the initial factor of the conception of fashion design. Pursuing one's own fashion with identity would make that fashion even more active and confident.

Eagle's syndrome is the term given to symtomatic elogation of the styloid process or mineralization of the stylohyoid or stylomandibular ligament. Since ossification of stylohyoid ligament at cadeva was fist described by De Manchetics in 1652 and Weinlecher described clinical symptom which produced by elongated styloid process and osteotomy of styloid process in 1872, Clinical symptom which include sensation of a foreign body on the pharynx, dysphagai, dysphonia, referred pain, and mouth opening disturbance was termed by Eagle as Eagle's syndrome. then, case reports of Eagle's syndrome are presented. in these cases, the patient's chief complaints included periauricular radiating pain, mouth opening disturbance, foreign body sensation, dysphagia, tenderness on the neck. Through vairous X-ray examination and palpation of tonsillar fossa, elongted styloid process were confirmed. Under the general anesthesia there were successfully removed out via transoral approach technique, described by Eagle. after resented styloid process, they were freed from the symptoms without further complication. Therefor we reported these cases treated by surgical resection of styloid process with good results.

This research presents a Reliability-Based Topology Optimization (RBTO) using Bi-directional Evolutionary Structural Optimization (BESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. Deterministic Topology Optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, RBTO involves evaluation of probabilistic constraints, which can be done in two different ways, the reliability index approach (RIA) and the performance measure approach (PMA). The reliability index approach (RIA) and the performance measure approach (PMA) are adopted to evaluate the probabilistic constraints. In order to apply the BESO method to the RBTO, sensitivity number is defined as the change in the reliability index due to the addition or the removal of the ith element. In the BESO, a mesh-independency filter using nodal variables is used to remove the checkerboard patterns. The optimal topologies of RIA and PMA are obtained very similarly. It is shown that RBTO based on BESO can be effectively applied from the presented examples.
