Background and Objectives : Brain death may lead to hormonal depletion, metabolic derangement and multiple organ dysfunction. We have carried out present study to examine the effects of brain death on the thyroid function, metabolic indices, and the severity scoring systems. Methods : 13 adults patients admitted for organ donation or brain death evaluation were examined after brain death was confirmed. Thyroid hormones measured were .thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and free thyroxine (FT4). The metabolic indices measured were arterial ketone body ratio (AKBR), lactic acid (LA), and base defiat (BD). as for reference to the severity scoring systems, APACHE Ⅲ and multiple organ failure score (MOFS) were assessed on the day of brain death confirmation. Arterial blood was drawn for all measurements. Results : As for the thyroid function, there were significant decreases in T3 (40.48±20.96 ng/dL) and T4 (3.47±2.15 ㎍/dL), but no significant change in FT4 (0.75±0.31 ng/dL) and TSH (1.12±1.37 uIU/mL) compared to the normal range. Significant decreases in AKBR (0.39±0.31) and BD (-9.46±5.83 m㏖/L), and significant increase in LA (2.57±2.46 m㏖/L) In metabolic indices, were shown, as for severity scoring systems, APACHE Ⅲ score (101.54±19.41) and MOF score (9.11±2.57) indicated a high mortality. There were significant correlation between thyroid hormones (r=0.565 -0.781) but no correlation among other indices. Also, significant inverse correlations were shown between base deficit and lactic acid (r=-0.660), APACHE Ⅲ score (r=-0.726) and MOF score (r=-0.604). The highest correlation was observed between APACHE Ⅲ score and MOF score (r=0.851). Conclusions : As for the thyroid function, significant decrease in T3 and T4, and almost normal range of FT4 and TSH imply the euthyroid sick syndrome. Abnormal finding of the metabolic parameters indicates an inhibition of the aerobic metabolic rate of the body as a whole. And the severity scoring parameters are compatible with high mortality.

There exists a major impediment to learning electricity which may illuminate why direct presentation of scientists' ideas is too aggressive a strategy. This impediment lies in thinking that electricity is used up and in envisaging the light bulb as a consumer. This view is based on a powerful idea which summarises much of our experience; it declares that 'things get used up', 'you cannot get something for nothing', and 'intuitive thinking'. To replace this view with scientific view, we made the analogy model. It is suggested that the analogy model is more effective in teaching electricity circuits than conventional teaching method.

Saccharomyces cerevisiea, which has been known as antistress compounds, was hydrolyzed by proteinase producing SCP-20. The addition effects of SCP-20 on the food intake regulation mechanism were studied measuring the expression amount of neurotransmitters, such as NPY and NOS, which can increase food intake in hypothalamus, and CCK, which can decrease food intake by using immunohistochemistry method. The 0, 2, and 5 g/kg SCP-20 was orally administrated to the experimental animals for one week. The expression of NPY and NOS was increased in the group of 5 g/kg administrated animals while that of CCK was increased in the group of 2 g/kg administrated animals. The results of this study suggested that SCP-20 may influence the control mechanism of oral dose-dependently. Further studies are needed to elucidate the roles of SCP-20 on the changes of food intake regulation controlling neurotransmitters.

Despite the fact that demented elderly cared at home accounts for over 90% of the total demented elderly, dementia-related researches in the field of environment have been limited to theories and experiments about design of facilities in Korea. As a result of hitherto researches and experiments on design of dementia treatment facilities, It was found that the design element of the treatment facilities similar to the design in the patient's own house has a therapeutic effect. The finding is supported by the examples of the advanced countries that have already reached an aged society and where the welfare policy for demented elderly recommends home-oriented care rather than Institutional care In the light of such development, this study assesses the adequacy of the current housing environments for the life quality of the families with demented elderly people and suggests desirable housing environment improvements that can meet the requirements. This study particularly puts the emphasis on the findings and summarizes the different requirements for improvements that vary according to the types and degrees of dementia. For this study, we examined 30 cases of subjects that were sorted out of the main caregivers of demented elderly living in the Seoul Metropolitan area using purpose sampling and also in-depth qualitative investigative method was employed. The results shows that the physical environment of housing has influence on the life quality of the families with demented elderly and the improvement of the housing environment is urgently required considering the fact that symptoms of dementia last 10 years on average up to 20 years from an attack of the disease. In such Improvement of the housing environment, it is important to work out a plan according to the type of dementia and degree of symptoms with a focus on the minimization of problematic behaviors and living disabilities of the patient, as different types and dementia show different symptoms. What's most important, however, is that housing development should be conducted in cooperation with the community so that welfare service for home care can be diffused across the whole community and housing environment for the families with demented elderly can be improved in a macroscopic viewpoint

Today, almost all families are quipped with computers. At the same time, we can find lots of side-effects because of computers. If young students, who tend to be unable to control their impulses once they are immersed in internet, the problem will be more serious. It could be happened that the young students can't distinguish the real from the image. Therefore, it is important to grasp the actual condition of juvenile Internet addicts and their practical life, and to come up with basic materials necessary for working out countermeasures. This study surveyed 339 high school students from three high schools in the area of Seoul. Data collection were collected from 22nd of December, 2003 to 27th of December 2003. The collected data were analyzed by SPSS program using T-test, ANAVA and Pearson correlation coefficient. The results were as follows: First, of the 333 respondents 9.61% of them were high-risk internet using group, 15.02% of them were potential-risk internet using group. 25% of then were identified as addicted group. Second, the more addicted the subjects are, the lower their level of school adjustment becomes. For the addicted group, it is difficult to adjust their school and to have a good relationship with friend. Third, the more addicted the subjects are, the lower their level of friendship becomes. The subordinate areas of friendship have same results as the level of Internet addiction and the extent of friendship. If students are addicted to Internet, it is difficult to find friends who can give them encouragement in practical life. Firth, there was a negative relationship between Internet addiction and school adjustment, and, there was a negative relationship between Internet addiction and friendship. Through this study we have seized the relationship between Internet addiction and school adjustment and friendship. As a result, the more addicted, the more difficult to adjust to school. And for the students who were addicted, it is difficult to make a friend.

일반적으로 골의 형태와 구조는 부착 근육의 활성과 밀접한 관련이 있다고 알려져 있으며,특히 악안면 형태와 저작근 기능과의 관계는 많은 임상 및 동물 실험을 통해 연구되어 왔다. 초음파검사는 임상적 적용이 용이하고 비용이 저렴할 뿐만 아니라 환자에 대한 유해성이 적어 의학분야의 여러 영역에서 널리 이용되고 있다. 이 연구의 목적은 교근의 두께와 악안면 골격 형태와의 상관성을 평가하는 것으로, 강릉대학교 치과대학 남학생 35명과 여학생 15명을 대상으로 하였다. 교근의 두께 측정에는 7.57MHz의 고해상도 직선 탐촉자에 의한 초음파진단장치가 사용되었고, 악안면 골격 형태의 결정은 측방 두부계측방사선사진 분석을 통해 이루어졌다. 이상의 계측치로부터 얻어진 결론은 다음과 같다. 1.남자에서 교근의 평균 두께는 안정 상태에서는 13.8±1.71mm,최대 교합 상태에서 14.8±1.77mm였으며 여자에서는 안정 상태에서 11.6±1.58mm, 최대 교합 상태에서 12.4±1.47mm로 나타났다. 2.교근의 두께는 남녀모두 안정 상태보다 최대 교합 상태에서 유의하게 증가하였다(P<0.05). 3.교근의 두께는 안정 상태와 최대 교합 상태 모두에서 남자가 여자보다 유의하게 두꺼웠다(P<0.05). 4.교근의 두께는 남자에서 안정 상태와 최대 교합 상태 모두 하악평면각과는 음의 상관 관계가 있고 하악지 고경, 전두개저 길이와는 양의 상관 관계가 있음을 알 수 있었다(P<0.05). 5.여자에서는 교근 두께와 유의한 상관 관계가 있는 두부계측방사선사진 분석 항목을 찾을 수 없었다(P<0.05), 이로써 초음파검사는 악골 근육의 기능을 평가하는 전통적인 방법에 대해 추가적인 정보를 제공해 줄 수 있을 것으로 사료된다. It is widely accepted that the shape and structure of bone are closely related to the activity of attached muscle. Numerous clinical and animal experimental studies indicated the significant effects of masticatory muscle function on maxillofacial mofhology. Recently, the development of ultrasonography has spread throughout different fields of medicine. In the clinical examinations, ultrasonography is a convenient, inexpensive technique to apply with accurate and reliable results. The aim of this study is to assess the thickness of the masseter muscle and its correlation to maxillofacial skeleton by examining 35 male and 15 female dental students at Kangnung National University. The masseter muscle thickness of the subjects were measured by ultrasonographic scanning with a 7.5MHz linear probe, and their maxillofacial morphology were investigated by lateral cephalometric radiographs. The relationship between the masseter muscle thickness and maxillofacial morphology of normal adult was statistically analyzed, and the following results were obtained. 1.The average thickness of male masseter muscle was 13.8± 1.71mm in the relaxed state and 14.8 ± 1.77mm at maximal clenching state, while that of female was 11.6±1.58mm and 12.4±1.47mm, respectively. Ethnic difference in thickness of the masseter muscle and maxillofacial skeleton was found when the results of many researchers were compared with those of this study. 2.The thickness of the masseter muscle in both sexes increased significantly at maximal clenching state than in relaxed state(P<0.05). 3.The masseter muscle thickness of male was greater than that of female both in the relaxed state and maximal clenching states(P<0.05). 4.In males, the thickness of the masseter muscle was negatively correlated with the mandibular plane angle and positively correlated wish the mandibular ramus height and antenor cranial base length(P<0.05). It may suggest that the male with thicker masseter muscle has smaller facial divergence. 5.No significant correlation was found between the masseter muscle thickness and maxillofacial morphology in females(P<0.05). Therefore, these data suggest that ultrasonography can add valuable information to the conventional examinations of masseter muscle function.

본 연구는 정보교육 프로그램이 갑상샘암 수술 환자의 심리 및 신체적 불편감 감소에 미치는 효과를 검정하기 위해 실시된 비동등성 대조군 전,후 시차 설계의 유사 실험연구이다. 자료수집 기간은 2006년 6월 17일 부터 9월 19일 까지 3개월간 이었으며, 연구 대상자는 일개 종합병원에 갑상샘암 수술을 받기위해 입원한 환자 가운데 6월 17일 부터 8월 3일 까지 입원환자 29명을 대조군으로 하였고, 8월 5일 부터 9월 19일 까지 입원환자 30명을 실험군으로 하였다. 연구도구는 심리적 불편감을 측정하기 위해 Derogatis 등(14)이 개발한 ‘자기보고식 다차원 증상목록(Multidimensional Symptom Inven- tory)검사를 사용하였고, 신체적 불편감 측정은 McCorkle & Young(16)이 개발한 도구를 사용하였다. 본 연구의 결과는 다음과 같다; 1) 정보교육 프로그램을 받은 실험군은 정보교육 프로그램을 받지 않은 대조군에 비해 심리적 불편감 정도의 차이는 통계적으로 유의한 차이를 보이지 않았다(p= .135). 다만 ‘근심 걱정’요인에서 유의한 불편감 감소효과를 보였다(p= 0.49) . 2) 정보교육 프로그램을 받은 실험군과 정보교육 프로그램을 받지 않은 대조군은 두군 모두 신체적 불편감 정도가 사후 유의한 수준으로 증가함을 보였다(p= 0.90). 결론적으로 본 연구를 위해 만들어진 정보교육 프로그램은 갑상샘암 수술 환자의 신체적 불편감 감소에는 효과적이지 못하였으나 심리적 불편감의 근심걱정 요인을 감소시키는데는 효과가 있음을 알게 되었다. Objectives: This study was designed as a non-equivalent control group pre and post-test quasi-experimental study to examine the effects of education program using information on the psychological and physical discomfort of patients undergoing operation for cancerous thyroid glands. Methods: The study covered for three months from June 17, 2006 to September 19, 2006. The subjects of this study were selected from those patients who were admitted in one of the general hospitals in order to receive the operation for cancerous thyroid glands. They include 29 control group patients who were hospitalized during the period of Jun 17th to August 3rd 2006, and 31 experimental group patients who were hospitalized during the period of August 5th to September 19th, 2006, respectively. The instruments utilized for conducting this study includes the Multidimensional Self-Report Symptom Inventory test originally developed by Derogatis & et al. (1983) for measuring psychological discomfort. And for measuring physical discomfort, the tools developed by McCorkle & Young (1978) was utilized. Results: 1) Hypothesis 1 “The level of psychological discomfort of the experimental group who completed the information education program would be decreased comparing with that of the control group who didn't complete the program” was partly supported (Worry & Anxiety factor: p= .049). 2) Hypothesis 2 “The level of physical discomfort of the experimental group who completed the information education program would be reduced comparing with that of the control group who didn't complete the program” was not supported (p= -.90). Conclusion: The information program provided for this study was proved to be not effective for decrease physical discomfort of the patients undergoing operations for cancerous thyroid glands but proved to be effective for decrease the anxiety factor of psychological discomfort.

김판희,이미연 미래유아교육학회 2004 미래유아교육학회지 Vol.11 No.2

본 연구는 유아의 프로젝트 활동이 유아의 자기효능감과 학습흥미에 어떠한 효과가 있는지, 그 효과는 유아의 정보처리유형에 따라 차이가 있는지를 알아보고자 하였다. 7주간에 걸쳐 프로젝트접근법에 따라 프로젝트 활동을 한 집단(n=20)과 교사중심의 단원중심 수업을 한 집단(n=20)을 비교한 결과, 사회적 자기효능감, 학업적 자기효능감 및 학습흥미에서 프로젝트 집단이 단원중심 집단보다 높은 증진을 보였다. 이 프로젝트의 효과는 유아의 정보처리유형에 따라 차이가 있었는데, 동시적 정보처리유형의 유아에게서는 모든 요인에서 프로젝트가 단원중심보다 효과적인 반면, 계열적 정보처리유형의 유아에게서는 프로젝트와 단원중심 사이에 차이가 약하거나 대부분 유의하지 않았다. This research was designed to investigate the effects of the project approach on young children’s social and academic self-efficacy as well as the level of learning interest, and also to find out whether there were any differences in these effects in relation to the children’s information processing type. K-ABC intelligence tests were conducted on 186 children of age from 4 to 5 in “D” Kindergarten in Daegu City in Korea in order to separate the children into two different groups according to their information processing type. Then from the two groups, 20 subjects of the sequential processing type and another 20 subjects of the simultaneous processing type were chosen by random sampling. Each of these two groups was then randomly divided into another two groups, each of which consisted of 10 subjects-one group for a project approach and the other for a unit approach. The project approach groups engaged for seven weeks in activities based on Helm and Katz’s(2001) project approach for young children. During the same period, children of the other groups engaged in unit-based activities of regular classes for the purposes of comparison. In order to assess the effects of the project approach, self-efficacy tests and an academic interest test were administered immediately before and after the experiments. The self-efficacy test consisted of a social efficacy test and an academic efficacy test. These efficacy tests were constructed based on questionnaire by Hee-Jug Woo(1993), Harter and Pike(1984), Ah-Young Kim & In-Young Park(2001), and Jinks & Margan(1999). The academic interest test was based on the concept of interest suggested by Pintrich and Schunk(2002). For the data analyses, MANCOVA was applied with the IQ scores as the co-variants with a = .05. The results of the analyses were as follows : 1. The project approach was more effective than the unit approach in increasing young children’s social and academic self-efficacy as well as their academic interest level. 2. There were significant interaction effects between the teaching approach and the information processing type. The simple effect analyses of the interaction showed that children of the simultaneous processing type showed a greater increase in the project approach than in the unit approach in all sub-factors of social self-efficacy(interpersonal relations efficacy, prosocial behavior) and academic self-efficacy(confidence, perceived self-confidence, and task difficulty preference), as well as academic interest level(concern for learning, a better learning attitude, and an increased learning persistence). However, children of the sequential processing type showed a greater increase only in social self-efficacy and in perceived self-competence(a sub-factor of academic self-efficacy) in the project approach than in the unit approach. These children didn’t show a difference between the two approaches in any of the other sub-factors. In conclusion, the project approach appeared to be more effective than the unit approach in increasing the self efficacy as well as academic interest, mainly for children of the simultaneous information processing type.
