The purpose of this study was to investigate the current status of chronic diseases according to obesity in the elderly older than age 65 using data from the 7th Korea National Health and Nutrition Examination Survey (2016~2018). The subjects of the survey were 3,245 elderly older than age 65 who participated in the health survey and nutrition survey, 45.8% of the subjects were males and 54.2% of the subjects were female. 37.5% of all the elderly were obese, and the females (42.4%) were more obese than the males (31.8%) (p<0.001). Diabetes, hypertension, and hypertriglyceridemia had a similar prevalence of 24.6%, 63.0%, and 12.7% in males and females, respectively. Hypercholesterolemia was higher in the elderly females (44.2%) than in the elderly males (24.9%) (p<0.001). Through the logistic regression analysis, it was found that the prevalence of chronic diseases was higher in obesity than normal in elderly males and females (p<0.001). The total food intake increased from 'under weight' to 'obesity' in males (p<0.01) and females (p<0.001). In the case of the elderly males, the higher the degree of obesity, the higher the energy intake (p<0.05), and 'pre-obesity' consumed the most energy in elderly females. As a result of this study, the higher the obesity rate of the elderly, the higher the prevalence of chronic diseases.

The mortality and morbidity caused by injury and poisoning has been major public health problem in Korea. This study was carried out to get information indispensable in developing prevention srategies peculiar to korean rural area. In this study 1.499 people of 496 households. who are living in five rural villages of Chooncheon City. Kang-Won Province. were interviewed in accordance with structured questionaire in 1996. The results obtained are summarized as follows: 1. The age-standardized annual incidence rates of injury and poisoning per 100 persons surveyed were 4.2 in males and 1.9 in females. The difference between sex was statistically significant. 2. The places where most of injuries and poisonings occurred were road 66.7% among males. road 31.6% among females. 3. The occurrence of the injuries and poisonings were clustered in intensive farming season in both males and females. 4. The laceration and stab wound were the most frequent nature of injuries in males and the fracture was the most frequent nature of injuries in females. The fracture. sprain were more frequent among males but sprain and contusion were more frequent among females. 5. Incidence rates of injuries and poisoning by cause were higher in traffic accidents among males. though falls among females. The cause specific incidence rate by age was high in traffic accident for 30-59 year age group. and for the aged people older than 60 years. 6. In the management pattern, 78.8% of the injuries and poisoning were received medical care in hospitals and clinics, and the duration of the treatment over 4 weeks in 37.0%. The results obtained indicate that organized community effort is urgently required to prevent injuries and poisonings in rural area.

The purposes of this investigation were to determine the validity of various methods (available anthropometric equations and near-infrared light interactance) for estimating body fat and to develop multiple regression equations for the prediction of body fat. Thirty-eight healthy males(age: 20.87$\pm$7.17 yrs) and 12 females(19.58$\pm$2.19 yrs) underwent hydrostatic weighing to determine body fat. Anthropometric measurements were taken of height, weight, nin skinfolds and thirteen circumferences. The results obtained are summarized as follows: 1) Relative body fat determined by underwater weighing was 12.08$\pm$5.21% for the males and 17.97$\pm$5.75% for the females. 2) Circumference and skin fold that had the highest correlation with the body fat were waist girth in males and females(r=0.60, r=0.96, respectively), and subscapular in males(r=0.68) and triceps in females(r=0.96). 3) Corss-validation of 18 selected equations on males revealed total errors ranging from 3.76% to 5.06%. Among these equations, M3(Pollock et al.) demonstrated the least total error. Total error of estimation by near-infrared(NIR) was less than that of available anthropometric measurement equations. The results of the cross-validation of 12 equations on females revealed that F3(Sloan et al.) was clearly superior in accuracy of prediction. 4) Correlational analyses showed that estimation of body fat by NIR measurement seemed to be more closely associated with body fat determined by underwater weighing in women than men, in older subjects than younger ones, and in fatter subjects than leaner ones.

Tributyltin chloride(TBTCl) was administered through discrete immersion(2 hr each) from the $18^{th}-25^{th}$ day after hatching(dph). At the doses of 1, 2, 4 and 8 ${\mu}g/L$, the immersion at 2 ${\mu}g/L$ ensured 93% masculinization and the highest survival of 75% after the treatment. TBTCl acted as a growth suppressant and the magnitude of its suppression was stronger in females. During the 300 day experiment, it postponed sexual maturity of females from 120$^{th}$ dph in the control to 240$^{th}$ dph in the females treated at 8 ${\mu}g/L$. It reduced spawning frequency(22-3 times) and cumulative fecundity(1,632-19 eggs) by reducing the number of vitellogenic eggs. In the treated males too, it reduced sperm motility(100-68 sec); consequently, fertilizability of the sperm cells drawn from these males was also reduced from 88 to 43%. Progeny testing showed that the cross between males treated at>2 ${\mu}g/L$ and normal females generated the presumed 'homogametic' males. Both the treated 'homogametic' and 'heterogametic' males could induce the females to spawn fewer eggs than that of the normal males. A normal female somehow deducted the differences between the control, treated and sex reversed males; it preferred a normal male over a treated one, and a treated one over the sex reversed male.

Purpose: To investigate factors influencing sexual harassment and the frequency of incidents among university students. Method: During 1-20 July 2004, 339 students from five universities in Busan, Korea, responded to a written questionnaire. The SPSS Program calculated descriptive statistics, chi square test, and logistic regression analysis of the data. Result: Of the total respondents, 69.3％ (62.6％ of the males and 77.2％ of the females), reported that they were victims of sexual harassment. Conversely, 72.5％ (males 84.3％; females 58.4％), indicated that they were sexual harassment offenders. Characteristics of the reported victims were significantly different in terms of class year, proportion of males to females in their academic department, and group norms regarding sexually harassing behavior. Characteristics of the admitted offenders were significantly different in term of proportion of males to females within their academic department, group norms, and awareness of sexual harassment. Factors predicting sexual harassment included gender, proportion of males to females in an academic department, the group norms regarding sexually harassing behavior, and the offenders experiences. Conclusion: This study suggested that occurrence of sexual harassment among university students were related to various factors. Prevention programs should be developed that focus on these factors.

English vowels can be divided into monophthongs and diphthongs depending on the number of vocal tract shapes. Diphthongs are usually produced with more than one shape. This study attempts to collect acoustical data of English diphthongs published by Hillenbrand et al.(1995) online and to examine acoustic features of the diphthongs for phoneticians and English teachers. Sixty three American males and females were chosen after excluding those subjects with different target vowels or ambiguous formant tracks. The author used Praat to obtain the acoustical data systematically at eleven equidistant timepoints over the diphthongal segment. Obvious errors were corrected based on the spectrographic display of each diphthong. Results show that the formant trajectories of the diphthongs produced by the American males and females appeared quite similar. When the female formant values were uniformly normalized to those of the males, almost a perfect collapse occurred. Secondly, the diphthongal movements on the vowel space appeared not linear due to the coarticulatory gesture for the following consonant. Thirdly, the average duration of the diphthongs produced by the females was 1.156 times longer than that of the males while the pitch ratio between the two groups turned out to be 1.746 with a similar contour over measurement points. The author concludes that English diphthongs produced by various groups can be compared systematically when the acoustical values are obtained at proportional timepoints. Further studies will be desirable on the comparison of English diphthongs produced by native and nonnative speakers.

The population dynamics of Pandalus gracilis was investigated in the southeastern coastal area of Korea between May 1998 and April 2000. Of the 4,127 specimens, 57% were identified as females, 39% as males, and 4% as transitional hermaphrodites. The number of females was greater than that of males and transexuals. A significant correlation was observed between the number of transitional hermaphrodites and ambient seawater temperature. Growth parameters were estimated using the modified von Bertalanffy growth function model incorporating seasonal variation in growth using the program ELEFAN. Females grew faster and reached a larger size-at-age than males (K=0.65/y and $L_{\infty}$=17.86 mm carapace length [CL] for females; K=0.51/y and $L_{\infty}$=14.70 mm CL for males). Mean size and age (95% confidence limits) at sex transition, calculated from growth parameters, were 7.07 mm carapace length and 1.05 years, respectively. The reproductive strategies of pandalid shrimps are discussed in terms of the type of sex transition.

This study was conducted to find gender differences in physical activity, dietary habit and nutrient intake in 4∼6th grade students in elementary school. Physical activity assessment showed that males significantly engaged in more vigorous activity with longer duration than females. It was found that females skipped their breakfast more often and had more snack than males. On the other hand, males were more indulged in peaky eating, despite their good practice of drinking milk. Twenty-four hour dietary recall revealed that energy intakes in both males and females were not sufficient. Furthermore, subjects, regardless of gender, consumed marginal intakes of Ca and Fe. Special attention should be given to marginal intakes of Ca in the subjects. Due to low Fe intake in females, more caution should be taken to include a meal which can enhance iron absorption. It might be suggested that effective intervention strategies need to be developed and implemented to choose nutrient dense foods and activities that lead to better health.

This research examined the relationships of individual and intergenerational variables with psychological well-being(PWB) of elderly females and the relative significance of the effect of these variables on PWB. Structured interview technique was used to collect data from 202 elderly females in Seoul who were recruited through quota sampling method. Two-way analysis of variance result indicated that interaction effect between aged and the presence of spouse on PWB was existed. Though most variables were significantly correlated with PWB of elderly females results of multiple regression analyses indicated that three variables-self-efficacy self-esteem affectional solidarity with adult children- significantly influenced PWB and three variabels-coresiding with the first son's family satisfaction with pocket money and contact solidarity-approached the significance level to the effect on PWB.

This study was performed to assess the nutritional status, frequency of visiting and necessity of nutrition programs for 157 elderly(male:49, female:108) visiting public health centers in Puchon. The purpose of the study was to provide the basic data for developing a nutrition service model. The subject were investigated by interviews with a questionnaire to obtain dietary data and other information related to public health center. Blood tests for analyzing biochemical status were also carried out. The elderly showed low income status. Ninety two percent of them showed their monthly income was less than 400,000 won and 72.6% was observed as having 30,000 won/month as their pocket money. The most frequent disease reported as having or being treated were hypertension(32.6%), rheumatic arthritis(28.5%), diabetes(10.2%), and stomach disease(8.2%) for males and hypertension(33.1%), diabetes(19.4%), rheumatic arthritis(16.7%), anemia(11.1%) for females. The nutrients whose daily intakes were less than 2/3 of RDA were calcium(37.5% RDA),vitamin A(49.9% RDA), iron(60.0% of RDA) and protein(62.0% RDA) for males and vitamin A(27.7% RDA), vitamin B$_2$(33.3% RDA), calcium(44.1% RDA), iron(53.3% RDA), and niacin(60.0% RDA) for females, respectively. Prevalence of anemia, assessed by hemogloben using WHO definition, were 4.1% for males and 18.5% for females. The percentage of males with hypercholesterolemia( 220 mg/dl) was 2.1% and 19.4% fir females, Two percent of males and 12.0% of females were observed as having a LDL-C higher than 165 mg/dl. The mean fasting blood glucose(FBG) level of males and female was 84.2 mg/dl and 101.7 mg/dl respectively. Two percent of males and 8.3% of females were found with a FBG higher than 140 mg/dl. Seventy one percent of elderly reported they were visiting public health centers at least once per week or more frequently. They were satisfied most with the low medical bills but showed the lowest satisfaction for the facilities of the public health centers. What the nutrition service programs wanted most was nutrition counseling and guidance.
