  • Background : Hepatocellular carcinomoma is the 3rd most common malignancy and the 2nd most common cause of death in Korea. The prediction of life-expectancy in terminal cancer patients is a major problem for patients, families, and physicians. We would like to investigate the prognostic factors of hepatocellular carcinoma, and therefore contribute to the prediction of the survival time of patients with hepatocellular carcinoma. Methods : A total of 91 patients(male 73, female 18) with hepatocellular carcinoma who were admitted to the hospital between January and lune 1995 were entered into the study, and data were collected prospectively on 28 clinical parameters through medical obligation record. We surveyed an obligation and local district office records, and confirmed the surivival of patients till July, 1996. Using Cox-proportional hazard model, give the significant variables related to survival. These determined prognostic factors. Life regressional analysis was used, there were calculated predicted survival day based on combinations of the significant prognostic factors. Results : 1) Out of 91 patients, 73 were male, and 18 were female. The mean age was $56.7{\pm}10.6$ ears. During the study, except for 16 patients who could not follow up, out of 75 patients, the number of deaths was 57(76%) and the number of survivals was 18(24%). 2) Out of the 28 clinical parameters, the prognostic factors related to reduced survival rate were prothrombin time<40%(relative risk:10.8), weight loss(RR:4.4), past history of hypertension (RR:3.2), ascites(RR:2.8), hypocalcemia(RR:2.5)(P<0.001). 3) Out of five factors, the survival day is 1.7 in all of five, $4.2{\sim}10.0$ in four, $10.4{\sim}41.9$ in three, $29.5{\sim}118.1$ in two, $124.0{\sim}296.6$ in one, 724.0 in none. Conclusion : In hepatocellular carcinoma we found that the prognostic factors related to reduce survival rate were prolonged prothrombin time(<40%), weight loss, past history of hypertension, ascites, and hypocalcemia(<8.7mg/dl). The five prognostic factors enabled the prediction of life-expectancy in patients with hepatocellular carcinoma and may assist in managing patients with hepatocellular carcinomal.

  • Over the past four decades reproductive behavior has changed rapidly in much of the developing countries. The average total fertility rate has fallen by half from six or more to near three today. Between 1960 and 2000 the largest fertility decline occurred in Asia and Latin America. The mortality rate has also decreased in most developing countries. The purpose of this study is to review the pattern and characteristic of demographic transition in developing countries. At first, this study focuses on the regional fertility and mortality transition. Africa, the total fertility rate is still high, can be match to the second stage of demographic transition. Similar case is found in Southern West Asia areas. However, the fertility rate has therd stage of demographic transition. The same pattern is found in Latin America. The mortality rate has also decreased in most of developing countries. It is interesting to find that there is a clear difference among developing countries. In terms of crude death rate, Latin American countries show the lowest rate. while African countries remain still high rate. About mortality, African countries show a high level in terms of both crude death rate and infant mortality rate. African countries also show the lowest level of life expectancy in the world. One of the reasons for low level of life expectancy in Africa is the widespread of AIDS in this areas. This study suggests that we should include 'AIDS' in the study of mortality in African countries.

  • Purpose: This study was done to identify the patterns and significant predictors influencing hospitalization of Korean men for alcohol use disorder. Methods: A descriptive study design was utilized. Data were collected using self-report questionnaires from 143 inpatients who met the DSM-5 alcohol use disorder criteria and were receiving treatment and 157 social drinkers living in the community. The questionnaires included Alcohol Use Disorders Identification Test (AUDIT), Alcohol Problems, Alcohol Expectancy Questionnaire (AEQ), Life Position, and The Korean version of the Children of Alcoholics Screening Test (CAST-K). Data were analyzed using descriptive statistics, t-test, ${\chi}^2$-test, F-test, Pearson correlation coefficients, and logistic regression with forward stepwise. Results: AUDIT had significant correlations with alcohol problems, alcohol expectancy, and parents' alcoholism. In logistic regression, factors significantly affecting hospitalization were divorced (OR=4.18, 95% CI: 1.28-13.71), graduation from elementary school (OR=28.50, 95% CI: 8.07-100.69), middle school (OR=6.66, 95% CI: 2.21-20.09), high school (OR=6.31, 95% CI: 2.59-15.36), drinking alone (OR=9.07, 95% CI: 1.78-46.17), family history of alcoholism (OR=2.41, 95% CI: 1.11-5.25), interpersonal relationship problems (OR=1.28, 95% CI:1.17-1.41), and sexual enhancement of alcohol expectancy (OR=0.83, 95% CI: 0.72-0.94), which accounted for 53% of the variance. Conclusion: Results suggest that interpersonal relationship programs and customized cognitive programs for social drinkers in the community are needed to decreased alcohol related hospitalization in Korean men.

  • This study is to investigate, from the perspective of implicit theory, what elements influence children's motivation to learn and how their configurations are different according to different sexes. One analysis was based on answers to a motivation questionnaire by fourth to sixth graders from four different cities in South Korea. The subjects children were most highly motivated to learn were math and science for boys, and math and English for girls, respectively. Factors influencing the motivation were near 30 in number, including later happier life, joy of learning, parental rewards, pleasure of being informed, and meeting parental expectations, among others. Another analysis was an exploratory and confirmative factor analysis on motivation to learn among 856 fourth to sixth graders randomly sampled from 7 different cities all over South Korea. Factors revealed to contribute to the motivated learning here were five factors of utility, interest, recognition, knowledge acquisition(being informed), and expectancy sufficiency. There were some differences in the structure of factors between sexes; importance was given to five factors of utility, interest, recognition, knowledge acquisition, and expectancy sufficiency in descending order for boys, and six factors of interest, utility, rewards, recognition, expectancy sufficiency, and competition for girls.

  • The purpose of this study is to analyze the influential factors on the change in life satisfaction of elderly households. In this study, single and couple elderly households were defined as elderly households and the 2nd, 3rd, and 4th data of the Korean Longitudinal Survey of Ageing (KLoSA) provided by the Korea Employment Information Service (KEIS) were used. And 677 respondents aged 65 and over who had replied to all 3 sessions were included in the final subjects. multinomial logistic regression analysis was conducted to examine the influential factors on life satisfaction by the type of elderly households according to consumption pattern and the result showed that there were common influential factors such as house owning status and subjective health status and the factors that influence specific types such as expectancy of standard of living. In addition, in the longitudinal analysis of life satisfaction of elderly households, individual satisfaction level was confirmed to reduce with time and the factors that influence the longitudinal change in the level of life satisfaction of elderly households was analyzed through the conditional model of a latent growth model. The analysis results showed that household type, house owning status, and subjective health status influenced the initial value of life satisfaction of elderly households while household type and expectancy of living standard influenced the change rate of life satisfaction of elderly households. Based on the results of this study, the followings are suggested. There is a need to improve the life satisfaction of old age by increasing the opportunity for self-realization of elderly households and also policy approach should be made selectively taking various types into consideration.

  • According to the Framework Act on Sustainable Infrastructure Management, which has been enforced since 2020, reservoirs should be managed to minimize life cycle costs caused by aging through preemptive management such as systematic maintenance and performance improvement. For maintenance in consideration of the life cycle, it is essential to derive the end of life due to continuous performance degradation as the common period increases. For this purpose, it is necessary to develop a performance-predicting model for reservoirs. In this study, a reservoir was divided into main complex facilities to develop a model for the maintenance of the life cycle. A model was developed for each facility. For model development, maintenance information data were collected under management by the Rural Community Corporation. The data available for model development were selected by analyzing the collected data. The developed model was used to predict the expected life expectancy of the reservoir in the current maintenance system and the expected life expectancy in the case of no action. By using the developed model, it is expected that it will be possible to support decision making in operation management and maintenance while considering the life cycle of the reservoir.

  • Due to a rapidly aging society, the future Korea mortality rate is important for planning national financial strategies and social security policies. Old age mortality statistics are very limited in their ability to project a future mortality rate; therefore, it is essential to accurately estimate the old age mortality rate. In this paper, we show that the CK model with a Relational model as a base model provides accurate estimates of old age mortality rates.
