본 연구는 비만도에 따른 한국인 남성 폐쇄성수면무호흡 환자의 측모 두부 방사선계측학적 특성을 파악하기 위하여 시행되었다. 이를 위하여 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원하여 수면다원검사 후 치과에서 측모 두부방사선계측사진 촬영을 한 87명의 성인 환자들을 체질량지수(BMI)와 수면무호흡지수(AHI)에 따라 비비만 단순코골이군(Non-obese, simple snorers), 비만 단순코골이군(Obese, simple snorers), 비비만 수면 무호흡군(Non-obese, OSA patients), 비만 수면무호흡군(Obese, OSA patients)의 4군으로 나누어 비교하였다. 그결과, 4군 중 비만 수면무호흡군의 수면무호흡지수가 가장 컸으며, 비만 수면무호흡군보다 비비만 수면무호흡군의 하악각이 더 크고 혀 길이는 더 작았다. 또한, 비비만 수면무호흡군보다 비만수면무호흡군의 설골이 더 전하방에 위치하였고, 수면무호흡지수에 영향을 미치는 기여 인자는 비만 수면무호흡군에서는 혀 길이, 비비만 수면무호흡군에서는 설골의 후방위치였다. 이처럼 비만 수면무호흡 환자와 비비만 수면무호흡 환자의 측모 두부방사선계측학적 특성과 기여 인자가 다르게 나타나므로, 치료방법도 따라서 다르게 선택해야 할 것이다. 비만 수면무호흡 환자들에게는 먼저 체중감량이 권고되어야 할 것이고, 비비만 수면무호흡 환자들은 폐쇄부위에 따라 구강 내 장치나 Nasal CPAP (continuous positive airway pressure), UPPP (uvulopalatopharyngoplasty) 등이 추천될 수 있을 것이다. Objective: The purpose of this study was to compare the cephalometric measurements of obese and non-obese Korean male patients with obstructive sleep apnea syndrome (OSA). Methods: Eighty-seven adults who had visited the Sleep Disorder Clinic Center in Keimyung University, Daegu, Korea were examined and evaluated with polysomnography (PSG) and lateral cephalogram. They were divided into 4 groups (non-obese simple snorers, obese simple snorers, non-obese OSA patients, obese OSA patients) according to AHI (Apnea-Hypopnea Index) and BMI (Body Mass Index). Results: The obese OSA group had the highest AHI among the 4 groups. The non-obese OSA group had a significantly steeper mandibular angle and shorter tongue length than the obese OSA group. The hyoid bone of the obese OSA group was positioned anterior and inferior as compared with the non-obese OSA group. Multiple regression analysis showed that tongue length in the obese OSA group and retroposition of hyoid bone in the non-obese OSA group were significant determinants for the severity of AHI. Conclusions: From a cephalometric point of view, the obese and non-obese pateints with OSA may be characterized by different pathogeneses. Therefore, they have to be managed by individualized treatment. For the obese OSA patients, weight control must be advised as a first choice and for the non-obese OSA patients, oral appliance, nasal CPAP, UPPP and others could be chosen according to the obstructive sites.

This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.

Background: People with insulin resistance has a higher risk of developing cardiovascular disease. This leads to the importance in diagnosing metabolic syndrome. The incidence of metabolic syndrome has increased significantly in korea because of an increased population of obese people and also the incidence of DM. There have been many studies done on the incidence of metabolic syndrome in the general population. Therefore, the authors have designed this study to identify the incidence of metabolic syndrome in patients with type 2 DM and also the associated characteristics in that population. Methods: The study included 169 adults over the age of 20 (84 males and 85 females) admitted to the endocrinology department of Chosun University between Jan, 1st 2005 and May, 31st 2006. Out of the people diagnosed with type 2 DM people were excluded when any of the physical measurements (height, weight, blood pressure, abdominal circumference) and blood measurements (TG, HDL-cholesterol, fasting blood sugar) were insufficient and when the patient was taking any drugs other than anti-hy-pertensive agents and oral anti-diabetic agents. Obesity and the other risk factors were defined by the Asian-Pacific guideline and 2001 ATP III of NCEP, respectively. Result: The each prevalence according to the metabolic syndrome criteria of the type 2 DM patients showed low HDL cholesterolemia with the highest incidence of 57.4% followed by hypertng1yceridemia(52.0%), obesity(40.9%) and hypertension(33.0%). The each incidence of diagnostic criteria in metabolic syndrome according to sex was different, In males, hypertriglyceridemia was the highest with the incidence of 57.7% followed by low HDL-cho1estero1emia(49.5%), obesity(40.9%) and hypertension (30.0%). In women, the incidence were low HDL-cho1estero1emia(64.8%), hyperthg1yceridemia(47.6%), obesity(45.0%) and hypertension(36.0%), in a descending order. The analysis between the diagnosis of metabolic syndrome in type 2 DM patients and the criteria showed that hyperthglyceridemia (correlative value 0.575) had the highest correlation followed by low HDL-cholesterolemia (correlative value 0.446), obesity (correlative value 0.350) and hypertension (correlative value 0.410). All the correlations were statistically significant with a p-value less than 0.01. Conclusions: Type 2 DM is a important factor of metabolic syndrome based on insulin resistance. The control of blood glucose with prevention and early diagnosis of the other factors related to metabolic syndrome in type 2 DM is important for preventing cardiovascular complications.

Background : It is one of the important daily activities for Korean students to use the Internet, and most of them go to FC bang. However, students uncontrolled Internet use causes compulsive Internet use, so called the Internet addiction. So we investigated the relationship between students internet use pattern and their Internet addiction. And also examined how internet addiction causes VDT syndrome. Method: We conducted survey with self-registered questionnaires for 1 months, from January to February 2000. On the questionnaire, we asked Internet use pattern to students in suburban area. To test the Internet addiction, this research adopted Dr. Young s Internet addiction self test, and also major 8 symptoms of VDT syndrome were tested. Results : There was not much difference in computer using time between at home and at PC bang, and among student s grade. We found 30.1% of the objects addicted to the internet, however, there was no relationship between Internet addiction and student s grade. We found statistically significant relationship between Internet addiction and VDT syndrome (p<O.o5) except ocular symptoms and dry mouth. Conclusion : As a result, we found that Internet adhction is related with the spending time on computer use, although there is no relationship between Internet addiction and student s grade. There are significant correlations between internet addiction and VDT syndrome. So internet addiction is not only social and psychiatric problem but a physiologic dsorder whch affect student s health.

목적 : 본 연구는 지방조직과 혈청의 PCBs와 DDE 농도를 측정하고, 이에 영향을 미치는 것으로 알려진 요인들과의 관련성을 평가하고자 하였다. 방법 : 유방암, 자궁내막증 등 유기염소계 화합물의 영향이 있는 것으로 알려진 호르몬 관련 질병을 제외한 부인과 환자 52명을 대상으로 지방조직과 혈청을 분석하였으며, 설문조사를 통하여 연령, 교육수준, 직업, 비만도, 흡연과 음주, 출산력, 수유력등을 조사하였다. 지방조직과 혈청의 PCBs와 DDE 농도는 가스크로마토그래피를 사용하여 측정하였다. 결과 : 지방조직의 경우, 13개 PCBs congeners 농도의 합은 중앙값이 48.29 ng/g, 기하평균값이 56.78 ng/g이었고, DDE 농도는 중앙값이 142.89ng/g, 기하평균값이 117.06 ng/g이었으며, 혈청의 경우는 PCBs congeners 농도의 합은 중앙값이 4.67 ㎍/L, 기하평균값이 4.85 ㎍/L이었고, DDE 농도는 중앙값이 1.75 ㎍/L, 기하평균값이 2.09 ㎍/L로 나타났다. 지방조직과 혈청의 DDE 농도 사이는 높은 상관성을 보였으나(r²=0.310, p=0,0002), PCBs는 상관성이 약한 것으로 나타났다(r²=0.029, p=0.2582). 영향요인을 범주화한 후 로그변환 시킨 지방조직과 혈청의 PCBs, DDE 평균의 차이를 분석한 결과, 지방조직의 DDE만이 출산자녀수(p=0.015), 초산연령 (p=0.014), 비만지수(p=0.035)와 연관성이 발견되었다 다중회귀분석의 결과 지방조직의 DDE는 출산자녀수가 적을수록, 초산연령이 늦을수록 증가하는 경향을 보였다. 결론 : 출산자녀수와 초산연령, 비만도가 지방조직의 DDE와 관련성을 보였으며, 또한 유기염소계 화합물의 장기간의 노출에 의한 영향을 평가하는데 있어서 혈청보다 지방조직이 더 유용한 생물지표임을 알 수 있었다. Objectives : This study was purposed to determine the levels of PCBs and DDE in adipose tissue and serum and to evaluate the relations with factors affecting these levels. Methods : We analyzed adipose tissues and sera from 52 gynecologic benign disease patients aged 27-78 years, except hormonal diseases such as breast cancer and endometriosis. We also surveyed age, education, occupation, body mass index (BMI), smoking, drinking, number of children, and duration of breastfeeding by questionnaires. Tissue and serum levels of PCBs and DDE were measured using gas chromatography. Results : The median and geometric mean levels of PCBs were 48.29 ng/g, 56.78 ng/g for adipose tissue and 4.67 ㎍/L, 4.85 ㎍/L for serum, and those of DDE were 142.89 ng/g, 117.06 ng/g for adipose tissue and 1.75 ㎍/L, 2.09 ㎍/L for serum, respectively. Adipose tissue and serum levels for DDE showed high correlation (r²=0.310, p=0.0002), but those of PCBs didn't (r²=0.029, p=0.2582). In analyses of the differences of the means of log transformed adipose tissue and serum PCBs and DDE levels for groups of potential covariates, only adipose tissue DDE levels were significantly associated with number of children (p=0.015), age at first birth (p=0.074) and BMI (p=0.035). In multiple regression analysis, adipose tissue DDE levels were significantly increased with decreasing number of children and increasing age at first birth. Conclusions : This study suggested that parity and adiposity were associated with levels of DDE in adipose tissue, and adipose tissue is a better biomarker than serum for evaluating the long-term exposure of organochlorines.

Drawing from contemporary goal perspective theories of achievement motivation, this investigation had purpose to the relationship of goal orientation and perceived motivational climate to intrinsic motivation, self-esteem, and sport performance in physical education settings. To test the dynamic Matching Model(goal-climate), this study also examined the interactional effects between goal orientation and motivational climate on cognitive and behavioral components of motivation. 218 male college student attending to physical education classes requested to complete the four instruments. The results of canonical correlations indicated that both task orientation and mastery climate positively related to reported intrinsic motivation. Task orientation and mastery climate positively related to self-esteem and sport performance, respectively. The results of Goal X Climate MANOVA procedures showed the interactional effect on intrinsic motivation. Subjects in task orientation and mastery climate increased in their intrinsic motivation(interest and effort) to sport activities in physical education classes. Matching between ego orientation and competitive climate had not effect on increased intrinsic motivation. This results partially supported the goats-climate matching model.
