본 연구는 서울시 지역주민을 대상으로 스트레스, 우울, 문제음주 간의 인과관계를 검증하고자 시도되었다. 본 연구는 서울시 S구이며, 전체 17개동에서 만 19세 이상인 남녀 주민을 층화집락추출법을 통해 표집된 1234명을 대상으로 하는 면접식 단면조사연구를 수행하였다. 구조방정식 모형을 사용하였으며, 측정모형에서 우울, 알코올장애의 내생잠재변수와 외생잠재변수인 스트레스 및 인구학적 변수(성, 연령, 결혼상태)를 이론변수로 설정하여 이들 간의 상관관계를 추정하였다. 또한 문제음주를 최종내생변인으로 우울을 매개변인으로 설정한 상태에서 경로분석을 실시하여 각 변인들의 상대적 중요성에 대한 평가를 시도하였다. 문제음주에 영향을 미치는 변수는 여성보다는 남성이($\beta=-6.64$, p < .001), 연령이 낮을수록($\beta=-.08$, p < .001), 스트레스가 높을수록($\beta=-.08$, p < .001), 미혼이 기혼($\beta=-1.15$, p < .05)의 순으로 경로계수가 유의하였다. 우울에 미치는 영향력은 스트레스($\beta=-.56$, p < .001)와 문제음주정도($\beta=-.15$, p < .001)의 순으로 경로계수가 유의하였다. 이상과 같이 우울이 직접적으로 문제음주에 영향을 주기보다는 스트레스로 인하여 문제음주가 유발될 수 있고 문제음주를 경유하여 우울에 영향을 미치는 것으로 드러났다. 이상의 연구결과를 종합해 볼 때 문제음주는 스트레스와 우울과 관련성이 크므로 우선적으로 스트레스를 적극적으로 관리하는 것이 중요하다. 또한 알코올과 관련한 통제정책으로 절대적인 음주량을 감소시키는 것이 필요하며, 문제음주자를 조기 발견하여 정신건강에 문제로 발전하지 않도록 하는 예방프로그램의 개발이 시급하다 하겠다.

Objectives: The purpose of this study was to assess the clinical and polysomnographic characteristics of Korean patients with obstructive sleep apnea syndrome (OSAS), especially in relation to differences due to age and gender. Methods: All subjects were consecutive patients who were proven to have OSAS with nocturnal polysomnography. They were interviewed with a structured interview format including sociodemographic information, past medical history, medication, and sleep-related history. Simultaneously, they were also given Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) to answer in order to check subjective sleep quality and subjective sleepiness. Results: Mean age of the 308 subjects was $49.5{\pm}$13.3 years, with 77.6% of the subjects being males and 22.4% of the subjects being females. The aging effects on the sleep architecture in Korean OSAS corresponded with normal aging, but with the effect of OSAS itself superimposed, the extent of aging effects was more marked than that of normal aging. The severity of Korean patients of OSAS was not correlated with age. When divided into age subgroups, significant correlation was found between RDI and BMI in patients of each subgroup of those in the 4th to 7th decades. The oldest subgroup (>70 years) described their subjective sleep quality as poorer than any other age subgroups, despite of less subjective drowsiness. The severity of OSAS and the change of sleep architecture of male subjects turned out to be severer than those of female ones. The female/male ratio of the subjects tended to increase with aging. Conclusions: The aging effect on the sleep architecture in Korean OSAS seems to be a mixture of the changes by normal aging and sleep disorder per se. The severity of OSAS was not correlated with age, but highly correlated with BMI. The severity of OSAS and the change of sleep architecture of male patients were severer than those of female ones.

Serum concentrations of Hanwoo steers and bulls as possible indicators of beef quality were analyzed to estimate their correlations with carcass traits. Blood samples were taken 2 months and right before shipping to abattoir and at the time of slaughter. And phenotypic correlation coefficients between serum concentrations and carcass traits were estimated. Beef yield index of steers was positively correlated with serum concentrations of total Protein (0.23), albumin (0.26), and calcium (0.31). But it was negatively co..elated with BUN (-0.30). Loin eye area was positively correlated with BUN (0.17) or with globulin (0.16). Back fat thickness was positively correlated with BUN (0.42) and inorganic phosphorus (0.20) being negatively correlated with total protein (-0.23), albumin (-0.33) and calcium (-0.33). Marbling score in the scale of 1 (scarcely marbled) through 9 (extremely marbled) was positively correlated with BUN (0.28) and negatively with IGF-I and calcium concentrations. Phenotype correlation coefficient of loin eye area with total protein concentration in the serum taken from steers right before shipment was estimated to be -0.16 and that with BUN was estimated to be -0.15. Serum concentrations of IGF, glucose, creatinine and on organic phosphorus from steers measured right before shipment were negatively correlated with respective correlation coefficient estimates as -0.21, -0.21, -0.19 and -0.18. Marbling score was negatively co..elated with serum creatinine (-0.16) measured at that time. Beef yield index of steers was positively correlated (0.31) with age adjusted calcium concentration in the serum taken at the time of slaughter. Correlation between body weight and BUN at slaughter was 0.17 At slaughter, loin eye area was negatively correlated with albumin (-0.19) and back fat thickness was also negatively correlated with age adjusted calcium concentration (-0.38). Marbling was negatively correlated with age adjusted calcium concentration(-0.17). Serum concentrations of testosterone, calcium and inorganic phosphorus taken in 2 months before slaughter were negatively but highly correlated with yield index(0.71, 0.67 and -0.71), respectively. Body weight at slaughter was positively was negatively correlated (0.67) with calcium level while dressing percentage was negatively (-0.69) correlated with serum glucose concentration, 2 months prior to slaughter. Correlation coefficients between back fat thickness and cortisol, between back fat thickness and inorganic phosphate were both positive (0.29 and 0.69). Marbling score was negatively correlated with creatinine (-0.81) and positively with BUN (0.87). Body weight loss during shipping was positively correlated with albumin and inorganic phosphate (0.77, 0.83). Yield index of bulls was positively correlated with serum testosterone concentration (0.66). Dressing percentage was positively and highly correlated with globulin (0.73). Back fat thickness of bulls, however, was negatively correlated with testosterone (-0.60). Loin eye area of bull carcasses was positively correlated with testosterone (0.40). Mar-blaine was negatively co..elated with creatinine (-0.55). Yield index of bulls and age adjusted HDLC concentration at slaughter was negatively correlated (-0.71). Dressing percentage of bulls was positively and highly correlated with globulin concentration (0.70). Back fat thickness was also positively correlated with HDLC (0.69) in the serum taken at slaughter. Correlation coefficients between carcass weight and triglyceride, between loin eye are and testosterone and between marbling score and creatinine or glucose were 0.51, -0.91 and -0.58, respectively.

Longitudinal serial cephalometric films in the every second year from fifty girls were used for the analysis of growth pattern of maxillary alveolar bone (MAE). Six parameters regarding MAB height were measured and were compared with stature and chronological age. Descriptive analysis. correlation coefficient test and linear regression analysis were done for the statistical analyses. 1. The height of MAE increased until 14 years although growth velocity was gradually decreased. which was different with stature growth pattern. 2. The correlation coefficients between chronological age and MAB height were high and had no statistical differences with those of stature and MAB height. In addition. the correlation coefficients between chronological age groups within each parameter of MAB were very high. 3. The growth amount of MAB could be predicted using linear regression analysis on the basis of chronological age data. The growth pattern between MAE and statue was quite different because of the growth pattern difference between skeletal and neuronal system. Therefore. growth pattern of Korean MAB must be considered in dental treatment of youth. Also. close relationship between chronological age and MAB height would be useful when clinicians want to predict growth amount of MAE for the dental implant treatment.

The purpose of this study is to investigate the drinking behaviors of adult mentally retarded persons(N=140) over the age of 18. It was also investigated whether gender, age, and pattern of employment create different result of drinking behaviors, whether there is correlation between variables associated with drinking behaviors for mentally retarded persons. 58.2 percent of respondent reported that they had consumed alcohol beverages sometimes prior to their having been interviewed. Average age of respondents who had consumed alcohol was 26.357 years and average age of first-use of alcohol was 22 years. 39.2 percent of respondent reported that they drink alcohol once a month. Beer(54.2 percent) was the most frequently consumed alcohol beverages. Average alcohol consumption per occasion was 1.494 cup, and 10.9 percent of respondent answered more than 5 cups per occasion. Regarding problems associated with drinking, 16 percent of respondent of AUDIT and 51.4 percent of Family CAGE answered that their children have drinking-related problems. Men(64.2 percent) drink more than women(43.6 percent) and experience more alcohol problem. Regarding drinking behaviors associated with the pattern of employment, supervised employment group(78.6 percent) was known as the most prevalent group of experiencing drinking. For the amount of drinking, gender(p<.05) and pattern of employment(p<.05) had shown the significant differences. There were significant positive correlation between the frequency of drinking and the amount of drinking, and AUDIT and Family CAGE.
