This study was to examine the effects of depression, avoidance coping and quality of life on suicidal ideation of elders living at home. A descriptive survey study was conducted with a survey of 509 older people in person 50 senior center at G city from November 30, 2017 to 1. The data were analyzed with t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression using IBM SPSS WIN 24.0 program. The mean score of the was depression $8.50{\pm}3.51$, avoidance coping style $12.36{\pm}3.41$, quality of life $7.26{\pm}1.97$ and suicidal ideation $6.16{\pm}1.78$. Suicidal ideation was had a negative correlation with Depression(r=-.219, p<.001) and a positive correlation with avoidance coping style(r=.277, p<.001). The result of the regression indicated that depression, avoidance coping style and gender explained 12.1% of variance in suicidal ideation. The results suggest that depression, avoidance coping style and gender were associated with suicidal ideation. Therefore it is necessary to develop strategies to reduce the depression, avoidance coping style and improve quality of life for community dwelling elders to reduce suicidal ideation.

This experiment was carried out to investigation the growth differentiation between direct sowing and transplanting on P. ginseng cultivated on field and underwood. The results were as follows: In direct sowing treatment, emergence rate of P. ginseng cultivated on field and under conifer forest was above 80%, but it was only 40% at cultivated under broad-leaved forest. And survival rate was directly diminished about 10% every year. In transplanting treatment, survival rate was also diminished every year, it was slighter than that of direct sowing treatment. The growth amount of P. ginseng cultivated underwood was poor, compared to field culture, but there was no significant between conifer forest and broad-leaved forest. In transplanting treatment of 1 to 6 year-root seedling, survival rate of P. ginseng cultivated underwood was equal or slightly good compared to that of cultivated on field. Among seedling age, survival rate of elder seedling was lower than that of younger seedling. In P. ginseng cultivated underwood, the annual growth increment of 1 and 2 year-root seedling increased slowly and continually, whereas, that of 3 to 6 year-root seedling stopped or decreased slightly.

Race and ethnicity are important factors which influence the elderIy's residential adjustment behaviors, although it is unclear whether this reflects influences unrelated to race and ethnlcity. Culturally, the norm of family supportoften obseved among various minority ethnic groups is likely to provide flexible family suppof for the elderIy. Economically, the life-long hardship ofminority groups is likely to force them to maintain extended family living arrangements simply to reduce expenses via economies of scale. Thecontroversy about the economic need versus the cultural prescription forextended living arrangements remains unresoIved because it fails to articulatethe meaning of family supports among many disadvantaged groups.This study aims to test previous economic and cultural arguments, byexamining ethnic differences iu the eiderIy's responsiveness to their health andeconomic problems. Two hypotheses about cultural influences on the elderly's resideutiai adjustment are examined. First, do elderly minorities receive famiiysupporis for longer periods when they are poor if economic and health status\ulcorner Second, do elderiy minorities receive family supports more often when their health status declines\ulcorner Using the Longitudinal Suvey on Aging from 1984 to 1990. this study employs Markovian multi-state life tables, and discrete and contonuous competing hazard analyses for the transition in living arrangements. The main results provide substantial evidence against the cultural resource thesis. Elderly minorities experience more frequent transition between living alone and living with relatives than white elderly persons when group differences in the extent of mortality and insititutionalization are controlled. The shorter timf of living alone among elderly monorities stems from their greater likehood of joining relatives as well as greater mortality and attrition rates than elderly whites. Coresidence of elderly whites with their relatives is more likely to occur in response to their needs for health care than of elderly whites. it implies that instability. not flezibility. characterrizes elderly minorities living arrangements.

This study was conducted to abbess dietary intake and eating habits of low-income persons aged 60 years or elder. 212 persons were surveyed between July 10 and August 17, 1978 ; 105 from the farming village of Yang-ju, Kyunggi province; and 107 from Karakdong, an area of redevlopment in the suburbs of Seoul. Results were as follows : 1 ) Family environment 84% of elderly persons surveyed, lived with their children; 13.2%, together as a couple; and 1.9%, widowed, lived alone. More than half on the households had an average monthly income of \50,000 to \30,000. The average Engel index was 61.2%. As for pocket money, 56.4% of male subjects had \l,000 to \7,000 per month, whereas 74% of female had less than \1,000. 2) Anthropometric measurements 59.9% of subjects were $70{\sim}90%$ of standard weight, 93% had an arm circumference only $60{\sim}80%$ of the standard. 3) Food and nutrient intake Carbohydrate provided 73.4 to 79.4% of total energy intake, whereas protein and fat accounted for 10.4 to 10.5% and 8.3 to 7.8%, respectively. Those over 65 years of age showed a somewhat greater dependence on carbohydrates for energy, than those under 65. Protein intake was only $42{\sim}52%$ of the recommended allowance. and the proportion of animal protein to total protein was only $2.1{\sim}9.3%$ far below the recommended allowance. Thus the protein nutrition of the subjects was proven to be inadequate qualitatively as well as quantitatively. Intake of energy and of all nutrients except vitamin A and ascorbic acid, were lower than recommended. 4) Correlational assessment The correlation coefficient between poor dental health, clinical sign score, appetite index, dietary balance and nutrient intake, was significant (0<0.01). Poor teeth, illness, and poor appetite were always associated with inadequate intake of energy and nutrients. The results of this survey reveal that many of elderly of the rural and urban poor show evidence of general malnutrition, The authours hope that this study will provide a back. ground and indicate the direction that community health and welfare programs may take to assure proper nutrition for the elderly.

In this paper, we use panel dataset from Korean linked worker-firm to analyse the effects of the workforce age structure on the productivity or labor costs. We measure 'labor productivity' as added value per capita, 'cost of labor' as labor cost per capita and estimate a dynamic panel model to study the effects of the workforce age structure on the productivity or labor costs. Empirical analysis results show that the workforce age structure is positively related to productivity and labor costs, but only up to the aged of 35-39. That is, we find that an increase in the proportion of younger workers or elder workers rather than the aged 35-39 has a negative effect on productivity and labor cost. In particular, the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 50 or older is increased instead of the aged 35-39 is higher than the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 30 or younger is increased instead of the aged 35-39. Our results exhibit that it is reasonable for firms to worry about declining productivity of elderly workers, whereas firms already used older workers efficiently, such as by adjusting their labor costs.

Antigenic localization in Parofonimn iloktsuenensis worm tissues (tegument, intestine and vitelline gland) in different developmental stages of 2 weeks, 3 weeks, 4 weeks, 5 weeks and 33 weeks from albino rats (Sprague-Dawley) infected with P iloktsuenensis was observed by electron microscopy. These worm tissues of different developmental stage of R iloktsuenensis was observed on electromicrograph by immunogold labeling method using R iLoktsuenensis infected rat serum of 10 weeks. Antigenic localization was demonstrated as labeling of gold particles in tissues on electronmicrograph. In tegument, gold particles were labeled on tegumental tissue, generally more numerous on secretory granules in tegumental syncytium 2 weeks than those on the other elder developmental stages, but there was a little variation in antigenicity according to individual worm tissue. In general, antigenicity in tegumental tissue was not strong (gold particles: 0.1-5/1 Mm2). In intestine, a large number of gold particles (15-18/1 Mm2) were labeled in intestinal epithelium. Gold particles were concentrated especially on secretory granules in cytoplasm, and gold particles were labeled not only in cytoplasmic protrusions, but also in intestinal luminal contents. Intencity of labeling of gold particles was not correlated with developmental stage of worms. In vitelline gland, a large number of gold particles were labeled on vitelline globules. The gold particles in vitelline globules (8- 11/1 Mm2) were concentrated in protoplasm among segmental globules . Key words: Pnragonimus iloktsuenensis, immunogold labeling method, tissue antigen ultrastructure.

Yu-Dong-Kong exercise is to produce heat from rubbing hands and is composed of 10 different types of exercise using warmed hands. The objective of this research is to evaluate the effect of Yu-Dong-Kong exercise on physical function and emotional state in elderly. The design of research is Nonequivalent Control Group Pretest-Posttest Design. The independent variable is Yu-Dong-Kong exercise, and the dependent variables are physical function and emotional state. Subjects are 18 elderly in the experimental group and 16 elderly in control group. All of them are above 60 year old and live in 1-city, Kyonggi-do. The exercise period was 4 weeks and data were collected from April to August in 1998. The exercise frequency was once a day. The exercise duration was from 10 to 20 minutes. The measurement tools are modified 1) Cornell Medical Index-Health questionnaire and 2) Geriatric Depression Scale. Collected data were analyzed by t-test and paired t-test based on the purposes of research using SPSS-Window package. The results are summarized as follows : 1. There was no difference in pre-exercise physical function between two groups (t=-.95, p=.35). 2. The hypothesis that 'physical function in the experimental group will be improved compared to the control group' was not supported by t-test(t=-.925, p=.362). However. the physical function in the experimental group showed much improvement than that in the control group. 3. The hypothesis that 'emotional state in the experimental group will be improved compared to the control group' was not supported by t-test(t=-1.715, p=.096). However, the emotional state in the experimental group showed much improvement than that in the control group. 4. The hypothesis that 'physical function will be improved in the post-exercise compared to pre-exercise' was not supported by paired t-test(t=.302, p=.766) However, a slight improvement in the physical function was found. For the further study, it is recommended to reevaluate the effect of Yu-Dong-Kong exercise through large number of subjects and long-term study. Also, a separate study with different type of subjects is recommended. In addition, continuation and compliance this strategy for exercise should be developed.

The purpose of this study was to identify latent classes of socioeconomic status and to explore whether those of socioeconomic status influenced self-esteem among elderly living alone. From the data of 2009 National Elder Abuse Investigation, 1,333 older adults who were over 65 years and living alone were analyzed. Latent class analysis, one-way ANOVA, and hierarchical regression analysis were performed to test the purpose of this study. Results of this study found 5 latent classes of socioeconomic status, named as high education-low income group, low education-low income group, middle education-low income group, high education-high income group, and low education-high income group. Next, there were significant differences in self-esteem depending on 5 latent classes of socioeconomic status. Finally, compared to low education-low income group, high education-low income group, middle education-low income group, high education-high income group, and low education-high income group showed higher levels of self-esteem, even after adjusting for confounding factors. Findings from this study suggested fundamental characteristics and public policy for elderly living alone.

This study aims to develop a reliable and valid Geriatric Reaction Inventory-Simplified Form (GRI-SF). Reaction inventory for measuring anger (Evans & Stangelang, 1971) is an assessment tool in a view of stimuli for measuring the level of anger invoked from the anger-triggered experiences. Yet, the inventory, comprised of 76 items, is sometimes incapable of finishing up the lengthy questionnaire. In the sense, a simplified form of RI is necessary for those lacks cognitive ability such as stroke patients or the elderly. In study 1, a full version of Reaction Inventory was given for the elder who are above 60, and ten items out of 76 was selected to form GRI-SF based on the psychometric theory. In study 2, the reliability and validity of GRI-SF was tested by another sample group of elderly with some additional examinations. The reliability was good with Cronbach's alpha of 0.79. Based on the fact that GRI-SF measures the personal trait anger, GRI-SF should not be only strong correlation with the scores of trait anger strongly, but be less correlated with scores representing other aspects of anger. As a result, GRI-SF score showed strong correlations with trait anger among other sub-categories of State-Trait Expression Inventory (STAXI), and was less correlated with anger-out score which reflects behavioral aspect of anger. Moreover, it is less correlated (r=.41) with hostility representing attitudinal or cognitive aspects of anger. Consequently, GRI-SF, constructed by this research, is verified to be a reliable and valid tool for anger measurement.

The purpose of this study was to find the attitude change for snack by military soldiers before and after entering military service. To investigate oral health status and improving activities, this survey was done for 318 soldiers at Gyeong-gi province Paju city and the results were as follows. After entering military service, the soldiers take more snacks than before and take snacks 2 or more times a day. Both smokers and non-smokers take more snacks after entering military service than before entering. The soldiers did not go dental clinic regularly. But they have lots of interests about oral health. As higher position and older, soldiers restrain themselves to taking sugar contained food, and the elder soldiers showed higher practical character for nutrition intake than younger soldiers. Private soldiers were least practical for brushing after meal and showed the highest level of fulfill for using fluoride contained toothpaste, regular scaling and checkup at dental clinic and flossing.
