Change in the future household members is closely related to the change in the size and structure of the population which, in turn, is affected by factors of fertility and mortality and the household itself due to changing social values on family. This study aims to estimate the number of households and to thereby analyze the characteristics of household, using a household projection method chosen by reviewing various methods for Korea. In selecting the method of estimating households, the irregularity of the source data should be carefully taken into consideration with a society like the Korean society which is changing rapidly. The review on the proojection methods suggests the breakdown of the ages into two groups, namely 34 years old or less and 35 years old or more, for projecting the households for Korea. Thus, the Exponential Method for the former age group and the Net Transitional Method for the latter are adopted in this study. As a result, the number of households is expected to increase from 12,956 thousand in 1995 to 20,006 thousand in 2030 or by 54% during this period. The average number of members per household will decrease from 3.3 persons in 1995 to 2.5 persons in 2030. One of the main features of change in the housohold structure will be a rapid increase in the number of one person households and a decrease in the number of households with three generations or more.

The self-employment can provide work time flexibility. Work time flexibility would be a critical factor for married females' labor supply considering allocation of their time to market work and household work. This study used the 1998 and 2000 Korea Labor and Income Panel Survey for the empirical analyses. Applying the bivariate probit model with partial observability, this study analyzed factors related to the choice of participation in labor market and choice of self-employment. Also, this study examined the effects of marriage and the presence of younger children on changes in decisions related to labor supply using the multinomial logit model: exit from the labor market, increasing and decreasing work hours. The presence of the younger children showed a significantly negative effect on the participation in labor market while positive, but insignificant, effect on self-employment. Compared with females working for others, self-employers without employees and unpaid family workers are less likely to exit labor market rather than increasing work hours. The self-employment would be a good alternative to evade females' career interruption and therefore to enhance the potential human resources.

The aim of this study is to optimize the light source combination which can maximize the capability of the illuminance and color temperature of circadian lighting apparatus. To achieve this goal, the circadian lighting apparatus was consisted of two different types of fluorescent lamps having different color temperature of 2000K and 8000K, respectively, and the capability of the illuminance and color temperature of circadian lighting apparatus was evaluated by optical simulation as the number of the respective lamps were varied. Considering the Kruithof's curve and exceptional cases, the ranges of illuminance and color temperature for the living activities were reclassified in 4 groups - gathering, studying, relaxing and sleeping - so that the target range of illuminance and color temperature of lighting apparatus was settled. As a result, in the case of adopting two fixtures in which four 2000K lamps and five 8000K lamps were consisted, respectively to one fixture, the highest illuminance was expected at 4000K and over 500lx of illuminance was calculated between 3000K and 6000K. Through the optimized combination of light sources, the range of illuminance and color temperature were calculated as $44{\sim}750lx$ and $2500{\sim}6500K$, respectively.

This study identifies the symbolism of cross symptoms of different classes during the modernization process based on the imagery of and , both of which are Korean films made in the same era of the 1960s. The study referred to a number of Korean family movie films in the 1960s, in particular and , which are notably different in ways of expression and in social class of the subject matter, and identifies how the films express the mixed aspects of the cross modernization period. The film uses a grotesque expressionist method to voyeuristically look into a newly emerging middle class family, and the deconstructive aspect of a family unit whose excessive desire leads to its own ruin; thus, the film presents a new perspective into the various social issues that emerge in the near future. In contrast, engages realistic depictions to describe in detail the deep conflict of pain and hope within the hardships of life from the urban poor through a deep family conflict. Ultimately, the two films expose the various social issues through the familiar and the unfamiliar that appear from the mixed aspects of the cross modernization period, in other words, the conflicting images of the traditional and the modern.

Thromboembolic disease associated with assisted reproductive techniques is considered to be extremely rare but most serious complication. The reasons for this are thought to hypercoagulable state characteristic of OHSS due to high serum levels of estrogen, hemoconcentration and reduced circulating blood volume, but is still unclear. The risk is increased those with rare hypercoagulable conditions such as antiphospholipid antibody syndrome, protein C deficiency, protein S deficiency, antithrombin III deficiency, and those with a personal or family history of thromboembolic disease. The majority of thrombosis reported were venous site but arterial thrombosis mostly intracerebral was reported 5 cases in Korea so far. We present a case of basilar a. thrombosis at 11 days after hCG injection. The patient developed the right hemiparesis, and recovered after intraarterial thrombolysis and transluminal angioplasty. Protein S activity was decreased and vWF antigen was increased. Decreased protein S activity was also found in previous reported 4 cases, so we suggest screening test for protein S in OHSS patients.

We analyzed 121 age estimation clients who had visited oral medicine clinic, Chonbuk National University Hospital, from January 2000 to December 2007 to evaluate its characters in Jeonllabuk-do. The obtained results were as follows : 1. There was distinct difference in sex distribution(Male : 58.7%, Female : 41.3%) and more than half percent(55.4%) was over 50's. 2. The difference between registered and alleged age was the most in more than 5 years, and most of them were over 50's. 3. There were more clients who wanted to increase their age than to decrease and was no prominent difference in sex. Age estimation clients who wanted to decrease their age were predominant under 10 years old and in 20's, and those wanted to increase were predominant in 10's and over 30's. 4. The most reasons to correct age were related to welfare benefit. The purpose of age estimation was different according to each age groups; welfare benefit was the most over 50's, occupation in 40's and 50's, friendship in 30's and 40's, sibling-related in 50's, employment in 10's and 20's. 5. Age was estimated by the attrition of permanent tooth and pulp/tooth ratio from 20 years, root apex closure for 10's and calcification of permanent tooth under 10 years old. In cases that were difficult to estimate by use of the attrition of permanent tooth and pulp/tooth ratio, age was estimated by missing time of permanent tooth and the change of mandibular angle with age. 6. The estimated ages were close to alleged age in 77.7% of clients but the rest(22.3%) was close to registered age.

We examine the clinical efficacies of fluoxetine in treating the children with selective mutism. In an 8-week open-label clinical study, 17 children with selective mutism are received 20-60mg/day of fluoxetine. Our results reveal that 13 subjects(76%) of 17 subjects improve statistically in within subjects comparison of pre- and post-treatment changes in the scores of Clinical Global Impression scale for mutism, Children’s Depression Inventory scale, and Revised Children’s Manifest Anxiety Scale. These data suggest that selective serotonergic antidepressants may be effective in treating selective mutism in children and adolescents.

It is an aim of this study to analyze a relation between modern medicine advertisements and body. Recently the academic world has discussed how comes it that the modernity had been formed. This trend is remarkable in the field of the history of everyday life. Because everyday life is connected with people's vivid experience. Especially in modern advertising it is in existence such as popular culture, consumer culture, sexuality, family, food, clothing and housing, disease. Since modern times the body has been reorganized into a new shape. Namely the premodern body that had been regulated by a status system is changed into modern body that have to form itself after the customs and values. We analyzed medicine advertisements in the early modern times and hoped to explain how modern people had understood their body. We applied Foucault's theory of discourse as a methodology. As a result of research, we came to the conclusion that there were several rules in the texts of medicine advertisements, which had formed a modern subject of pain. There was a disciplinary power such as a internalization of clinical eyes, self-watch in medicine advertisements. These advertisements contributed to the formation of subject of pain and related to the state power.
