Purpose of this study : In 2001, this study that investigate actual conditions about adaptation degree of Korean social life of the North Korean defectors was carried out to 151 people that succeed in chases among 200 the North Korea defectors answer in study. Purpose of this study is as following. First, we wished to search change aspect of actual conditions about South Korea society adaptation of the North Korean defectors who take part in the first investigation for past 3 years. Second, we wished to search difference of adaptation aspect by populational and social element. Third, We wished to suggest things that can be beaconed to efficient support policy of government or private organization and successful South Korea social adaptation method which support the North Korean defectors on the basis of study finding about change of adaptation aspect of the North Korea defectors. Methods of Study : We designated 200 Panels to study and survey actual adaptation conditions of the North Korean defectors on South Korea society synthetically and for long-term. So, chasing about 151 people was possible in 2004. We are fertilized and supplement the questionnaire forming in 2001 and composed the new questionnaires to part of a life, mental state, Body and health. This study among them investigated a standard of living of the North Korean defectors. In this process, interviewer directly asked and recorded questions to reduce individual variation of people who receive interview. Study Results : Government's residence support policy about North Korean secession inhabitants was generally attained as effective and suitable for North Korean inhabitants' early South Korea settlement. Only, government need to discuss about North Korea secession inhabitants' residence support more variously for long-term. Second, education should be supported more actively and variously. Suitable point of education for their needs should make a effect of vocational training or education maximize. This is a very important part. Third, they need guidance and education that can receive more easily law support. Fourth, medical supports and health cares should be achieved continuously and systematically to them since they arrived in South Korea. To supports and studies North Korean secession inhabitants has the large significance to gain a foothold about reunification of North and south. Their South Korea society adaptation is becoming topic of conversation among South Korean. An atmosphere of unity is elated. And interest degrees about North Korean are actually rising as exchanges between South and North Korean is activated. Therefore, the adaptation study about North Korean secession inhabitants will have to be expanded in studies for South Korean, not to be limited in studies for North Korean.

This paper describes several tools which are useful for improving the accuracy resulting from shape-based registration: constraint analysis, constraint synthesis, and online accuracy estimation. Constraint analysis provides a scalar measure of sensitivity which is well correlated with registration accuracy. This measure can be used as a criterion function by constraint synthesis, an optimization process which generates configurations of registration data which maximize expected accuracy. Online accuracy estimation uses a conventional roo-tmean-squared error measure coupled with constraint analysis to estimate an upper bound on true registration error.

Objectives : The aim of this study was to examine the change in attitudes and satisfaction level of North Korean defectors in South Korea over a 3 year period (2001-2004). Methods : In our first study in 2001, a total of 200 detectors were interviewed. In the follow up study after 3 years, 151 defectors were re-interviewed by an in-person interview. Results : The level of satisfaction to the governmental support policy to defectors decreased significantly. However, the general level of satisfaction increased slightly (from 3.52 to 3.56 ; 5-score scale). This shows that North Korean defectors are stably adapting to South Korean society. The level of satisfaction significantly correlated with the defectors' confusion of the different value systems, the defectors' understanding of the South Korean people, satisfaction with their physical and mental health, and the Prejudice of South Korean people to defectors. In terms of the attitudes, the type of schooling, the military service and the communist party membership in North Korea were not related to the change in attitude. However, there was a significant correlation with gender and age. Women showed a greater change in attitude compared to men. Older people had difficulty in understanding the South Korean people, but they showed little psychological affiliation to North Korea. Moreover, they showed a high level of satisfaction with the economic situation in South Korea and had an optimistic viewpoint for their future than younger people. Even though many defectors attended churches, religion was not associated with the level of satisfaction or their change in attitude. Conclusion : The factors that influence the level of satisfaction and attitudes of North Korean defectors have changed over 3 years. Therefore, the government, nongovernmental organizations (NGOs) associated with defectors and the churches need to be more sensitive to these changes and make plans to support the adaptation of defectors to South Korean society.

전 흉벽통증을 호소하던 고령의 환자가 강직성척추염으로 확인 된 LOAS의 한 예로 고령의 환자에서도 염증성 관절염의 원인으로 LOAS가 가능하며 전형적인 임상양상과는 구별되는 비전형적인 증상패턴을 보일수 있음을 나타내는 증례이다. Ankylosing spondylitis(AS) is the major subtype of an interrelated heterogeneous group of inflammatory rheumatic diseases now named spondyloarthritides. Clinical features of this group include spinal and peripheral joint oligoarthritis (predominantly of the lower limbs), enthesitis, and at times, specific organ involvement such as anterior uveitis, psoriasis, and chronic inflammatory bowel disease. Clinical onset of AS after the age of 45 years is uncommon. Late-onset AS(LOAS) is characterized by severe disease, marked elevation of laboratory measurements of inflammation, and more frequent involvement of the peripheral joints (predominantly the shoulders) and the cervical spine as compared with early-onset Late onset AS. We report a case of LOAS with atypical symptom. We described a 50-year-old patient who presented with chest wall pain mainly, marked elevation of laboratory inflammatory markers, severe disease course and was successfully treated with anti-TNF inhibitor.

Structure-Reactivity Correlations in Nucleophilic Displacement Reactions of Y-Substituted-Phenyl X-Substituted-Cinnamates with Z-Substituted-Phenoxides

Son, Yu-Jin,Kim, Eun-Hee,Kang, Ji-Sun,Um, Ik-Hwan Korean Chemical Society 2013 Bulletin of the Korean Chemical Society Vol.34 No.8

Second-order rate constants ($k_N$) have been measured spectrophotometrically for the nucleophilic displacement reactions of 4-nitrophenyl X-substituted-cinnamates (4a-4e) and Y-substituted-phenyl cinnamates (5a-5e) with Z-substituted-phenoxide anions in 80 mol % $H_2O$/20 mol % DMSO at $25.0{\pm}0.1^{\circ}C$. The Hammett plot for the reactions of 4a-4e with 4-chlorophenoxide (4-$ClPhO^-$) consists of two intersecting straight lines, which might be taken as a change in the rate-determining step (RDS). However, it has been concluded that the nonlinear Hammett plot is not due to a change in the RDS but is caused by stabilization of the ground state of substrates possessing an electron-withdrawing group in the cinnamoyl moiety through resonance interactions, since the Yukawa-Tsuno plot exhibits an excellent linear correlation with ${\rho}X=0.89$ and r = 0.58. The Br${\o}$nsted-type plot for the reactions of 4-nitrophenyl cinnamate (4c) with Z-substituted-phenoxides is linear with ${\beta}_{nuc}=0.76$. The Br${\o}$nsted-type plot for the reactions of Y-substituted-phenyl cinnamates (5a-5d) with 4-chlorophenoxides (4-$ClPhO^-$) is also linear with ${\beta}_{lg}=-0.72$. The Hammett plot correlated with ${\sigma}^-$ constants for the reactions of 5a-5d results in a much better linear correlation than that correlated with ${\sigma}^o$ constants, indicating that a partial negative charge develops on the O atom of the leaving aryloxide. Thus, the reactions have been concluded to proceed through a concerted mechanism.

Purpose: This study investigated the immediate biomechanical effects of unilateral mastication for 10 minutes on the temporomandibular joint (TMJ) with 21 healthy adult participants. Methods: The gum group chewed gum on the right side for 10 minutes, and the control group rested for 10 minutes. Biomechanical data were obtained using a three-dimensional infrared camera before and after intervention. An independent t-test assessed the variation of kinematic data to identify differences between before and after intervention. Results: Among biomechanical variables, the gum group’s length of the left forehead middle region and the temporomandibular joint angle decreased compared to the control group (p<0.05). Conclusion: Caution with unilateral masticatory activity is recommended, as unilateral mastication causes biomechanical changes due to excessive load on the soft tissues of the contralateral TMJ.

폴리페닐렌 설파이드(PPS) 수지는 용융온도가 290℃ 이상이며, 내화학특성이 매우 우수한 결정성 슈퍼 엔지니어링 플라스틱이다. 소재가 지닌 우수한 특성으로 금속소재를 대체할 수 있는 화학 소재로 주목받으면서 선진국에서는 관련된 많은 연구가 진행되고 있지만, 국내에서는 소재가 지닌 우수한 특성에도 불구하고 아직 다양한 연구가 진행되지 못하고 있다. 본 연구에서는 PPS 수지의 금형 온도조건 변화에 따라 달라지는 PPS의 결정화도를 분석하였으며, 결정화도에 따른 수지의 물성변화 경향을 분석하였다. PPS 소재를 적용한 부품의 금형온도에 따른 물성변화 값을 측정하여 시편 사출물과 강성 특성을 비교 분석하였다. Polyphenylene sulfide (PPS) is well known semi-crystalline super engineering plastic which is having a very high melting temperature (above 290℃) and strong chemical resistance. Research on replacing metallic materials with PPS is going on due to its superior properties. However, PPS is the material that does not have much attention in Korea as compared to the other developed countries. In this research, the crystallinity of the resin was influenced by the mold temperature, as a result, physical properties such as tensile strength, thermal properties were changed. Analyses were carried out with specimen and automotive molded part.

일반 느타리 13품종과 색상 느타리 5품종을 사용하여 아미노산 및 polyphenol, β-glucan 함량을 분석하고, 생리활성으로 항산화 및 항암, 항고혈압, 항혈전, 항당뇨, 항염활성을 측정하였다. 느타리버섯 18종의 아미노산 분석결과 전반적으로 감칠맛을 내는 glutamic acid 함량이 비교적 많이 함유되어 있었고, 필수아미노산 성분도 고르게 분포되어 있었다. Polyphenol 함량에서는 전 품종에서 20 mg% 함량이상을 나타냈으며, 노랑느타리(R)가 39.13±0.82 mg%로 가장 높았다. β-glucan 함량은 노랑느타리(R)에서 37.67±0.22%로 가장 높았으며, 그 외에 원형1(C), 장안PK(A)에서 각각 28.75±0.61%, 27.95±0.33%의 순으로 나타났다. 전자공여능에서는 노랑느타리(R) 버섯의 DPPH IC50값이 2.93±0.44 mg/mL로 가장 낮아 항산화 활성이 가장 우수한 것으로 나타났으며, 세포독성 실험에서는 노랑느타리(R) 에탄올 추출물 1% 처리시 신장 암세포에 대해 36.90%의 세포 억제율을 보였다. ACE 저해활성의 경우 노랑느타리(R) 에탄올 추출물 1%농도에서 60.5±0.2%의 저해율이 측정되었고, 흑평(B) 56.7±1.1%, 여름(H) 52.4±1.3% 수준으로 나타났다. 항혈전 활성에서는 3%농도에서 흑평(B)과 삼복(G)을 제외한 나머지 느타리버섯 에탄올 추출물에서 50%이상의 용해 활성을 보였으며 노랑느타리(R)에서 거의 plasmin과 동등한 활성을 나타냈다. 항당뇨 활성에서는 노랑느타리(R)의 경우 50.5±0.8%의 비교적 높은 효소저해율이 측정되었고, 항염활성에서는 노랑느타리(R)에서 68.4±0.3%의 억제율이 측정되었다. 이상의 결과로 일반 느타리 13 품종과 육종 재배된 색상 느타리 5품종 중 노랑느타리(R)가 가장 우수한 생리활성을 나타내 향후 기능성 소재로의 활용가능성이 기대되었다. In this study, the anti-oxidant, anti-tumorigenic, anti-hypertensive, anti-thrombic, anti-diabetic, and antiinflammatory properties of 18 different species of genus Pleurotus were investigated. In addition, the amino acid, β-glucan, and polyphenol content were also measured. All species contained more than 20 mg% of polyphenol with the highest contents found in Pleurotus cornucopiae var. citrinopileatus (yellow pleurotus) (39.13±0.82 mg%). The β-glucan contents was also the highest in yellow Pleurotus (37.67±0.22%) followed by Won-Hyeong1 (C, 28.75±0.61%) and Jang-an PK (A, 27.95±0.33%). The yellow Pleurotus exhibited the highest antioxidant activity as assessed by the DPPH scavenging rate with an IC50 value of 2.94±0.44 mg/mL. Ethanol extracts from the yellow Pleurotus treated at 1% concentration showed cytotoxic activity up to 36.9% in the human embryonic kidney 293T cell lines. The yellow Pleurotus also showed the highest inhibitory effects on ACE activity (60.52±0.2%). Finally, the yellow Pleurotus exhibited anti-diabetic and antiinflammatory properties as shown by inhibition of α-amyloglucosidase activity (50.5±0.8%) and nitric oxide production (68.4±0.3%). Taken together, our data indicate the yellow pleurotus is a promising functional food ingredients.
