In order to obtain basic data for a health promotion program of hair dressers, the health promoting behavior of some hair dressers was assessed with the related factors such as general characteristics and cognitive-perceptual factors. The subjects were 245 hair dressers working at beauty shops having at least two hair dressers. The data was collected by a questionnaire from October 14 to October 20, 2001. The results were as follows： 1. The mean score of health promoting behavior conducted by the hair dressers was 31.17 out of 50.00 in total score. 2. The score of the health promoting behavior was statistically different according to marriage, on-duty hours, holidays, satisfaction in the job, perceived health status, perceived fatigue, health concept, and self-efficacy (p＜.05), while it was not statistically different according to gender, religious faith, residence, eduation, economic levels, career in the job, average income, medical care insurance, employment insurance, control of fortuity, and control over other persons. 3. The health promoting behaviors in the hair dressers showed positive correlation with self-efficacy and internal control, while it showed negative correlation with control over other people, control of fortuity, health concept, and perceived fatigue. 4. The Regression analysis results of the questionnaire showed that perceived fatigue, health concept and office hours were significant factors but the age, the fact of being single or couple, position at the job, holidays, satisfaction of the job, self-control and stresses from other people and self-efficiency appeared insignificant. In conclusion, the hair dressers with less perceived fatigue and better cognitive health concept and short duty hours showed better health promoting behavior. So, In order to conduct health promoting behaviors of hair dressers, the method will need to control of working time and perceived fatigue.

The purpose of this study is to investigate the relations between spouse's self-disclosure and marital adjustment. A measurement tools used for this study are self-disclosure scale, which was adapted and reproducted from Jourard's Self-Disclosure! Questionnaire(JSDQ), and marital adjustment scale, which was modified and supplemented form Dyadic Adjustment Scale (D.A.S). developed by Spanier. The subjects were 154 married couples dwelling in Seoul and questionnaires are recorded separately by both spouses. Statistical methods such as frequency, percentage, mean, standard deviation, one way ANOVA and pearson correlation were used for data analysis. The results of this study are as follows; 1) For husband, self-disclosure degree was significant difference according to level of education. That is, the more husband was higher level of education, the more husband tended to disclose to wife. 2) Among the variables to have influence on the marital adjustment, level of education and marriage pattern had influence on wive's martial adjustment and family income and marriage pattern had influence on husbands' marital adjustment. 3) Wives were higher disclosed than husbands and wives were more disclosed than perceived husbands' disclosure. 4) There were positive correlation between the self-disclosure of husbands and the marital adjustment of wives. (r+.3872, p<.005) And there were positive correlation between the self-disclosure of wives and the marital adjustment of husbands. (r=.4997, p<.005) 5) For wives, the perception of husbands' disclosure correlates with wives' marital adjustment. (r=.4592, p<.005) For husbands, the perception of wives' disclosure correlates with husbands' marital adjustment.(r=.5610, p<.005) From this results, full and honest self-disclosure is needed for high marital adjustment of a married couple. In the future, a study on the relationship between self-disclosure and marital adjustment is need to various measure of many subject.

Childcare related studies have focused on the characteristics of care work, policy aspects, user family satisfaction, and job satisfaction of childcare helpers. But there have been few studies on family system characteristics that support childcare givers. Thus, this study conducted on the topic, "How to characterize the family resilience of long-term childcare givers?" The subjects belong to a healthy family support center in U. City, who belong to a group with an income in the top 20 % of about 20 persons working for more than 3 years. In an interview, qualitative questions were used Walsh's family resilience. The results are as follows. First, they had economic hardship, but their family would stand together and build up a family's power based on the couple's faith. They had a family role model based on their parents' family that included inherited maternity qualities from their mother. Second, the flexibility of the family organization changed to autonomous or co-role type and the connectivity. Especially, they appear as a family's leader. Third, their family communication was active, shared-care, responsible and passionate with family affection and understanding. The conclusions results are as follows. Participants were high school graduates as well as had work experience. They were characterized by positive family energy, a family belief system, family-based resources, flexibility, connectivity, open family communication and expression skills. Therefore, it can be suggested that it is necessary to check the family's resilience during an interview for the reliable, long-term supply of human resources for childcare activities.

The purpose of this study is to investigate factors affecting Korean Baby Boomers' life satisfaction. Using data from Demographic Profiles and Welfare Needs of Middle Aged Persons(2010), this study focuses on whether there is a gender difference in predictors of life satisfaction. Analysis results show that there is a significant variability in predictors of life satisfaction by gender. Couple satisfaction, self-rated health status, and expectations for the standard of living after 10 years were significant for both male and female models. It was noticeable to report that internet use level and monthly household income were unique predictors for male model; spouse parent care burden and parent-child satisfaction were unique predictors for female model. These findings suggest that it is vital for policy planners to take gender differences into account when designing and formulating public policies for Korean Baby Boomer.

The purpose of this study is to provide empirical findings about intragenerational and intergenerational discrepancies in eldercare attitude and behavior in Korea. Specifically, intragenerational discrepancies refer to phenomena in which eldercare attitude and behavior diverge from each other within the caregiving and care-receiving generations, respectively. Intergenerational discrepancies, on the other hand, refer to two kinds of phenomena, one in which eldercare attitudes are different between caregiver and care-receiver and the other in which eldercare behavior is differently recognized between the two parties. For the last couple decades, these kinds of discrepancies tended to be simply assumed without any coherent theoretical and/or empirical rationales. Thus, the current study tried to investigate the degree, pattern, and characteristics associated with the discrepancies. Analysis of data collected from 276 matched pairs of caregivers (i.e., daughters-in-law) and care-receivers (i.e., the elderly) in Kwangju and its suburb areas has indicated a substantial amount of both intra- and inter-generational discrepancies. In other words, both caregivers and care-receivers were found to be experiencing huge discrepancies between attitude and behavior in their respective generation: the factual discrepancies in attitude between the two generations were quite salient: the cognitive discrepancies in behavior between them were salient, too. In addition, it was also found' that the extent to which the discrepancies became salient differed for the three subdimensions of eldercare (i.e., emotional, economic, and physical care), and that such discrepancies have intimate relationships with a set of sociodemographic characteristics for caregivers - notably, age, educational attainment, area of residence, household income - on the one hand, and those for care-receivers - notably, gender, age, educational attainment, cohabitation, family size, inheritance, owned property - on the other. A series of theoretical, empirical, and clinical implications stemming from the findings were suggested and fully discussed in the context of Korean society.

For the study of fine-scale structure and dynamics in the solar chromosphere, the Fast Imaging Solar Spectrograph (FISS) was installed in 1.6m New Solar Telescope at Big Bear Solar Observatory in 2010. The instrument, installed at a vertical table of the Coude lab, is properly working and producing data for science. From the analysis of the data, however, we noticed that a couple of problems exist that deteriorate image quality : lower light level and poorer resolution of the CaII band data. After several tests, we found that the relay optics at the right position is crucial role for the spatial resolution of raster-scan images. By using resolution target, we re-aligned relay optics and other components of the spectrograph. Here we present the result of optical test and new data taken by the FISS.

Objective: Preimplantation genetic diagnosis (PGD) is an assisted reproductive technique for couples carrying genetic risks. Charcot-Marie-Tooth (CMT) disease is the most common hereditary neuropathy, with a prevalence rate of 1/2,500. In this study, we report on our experience with PGD cycles performed for CMT types 1A and 2F. Methods: Before clinical PGD, we assessed the amplification rate and allele drop-out (ADO) rate of multiplex fluorescent polymerase chain reaction (PCR) followed by fragment analysis or sequencing using single lymphocytes. We performed six cycles of PGD for CMT1A and one cycle for CMT2F. Results: Two duplex and two triplex protocols were developed according to the available markers for each CMT1A couple. Depending on the PCR protocols, the amplification rates and ADO rates ranged from 90.0% to 98.3% and 0.0% to 11.1%, respectively. For CMT2F, the amplification rates and ADO rates were 93.3% and 4.8%, respectively. In case of CMT1A, 60 out of 63 embryos (95.2%) were diagnosed and 13 out of 21 unaffected embryos were transferred in five cycles. Two pregnancies were achieved and three babies were delivered without any complications. In the case of CMT2F, a total of eight embryos were analyzed and diagnosed. Seven embryos were diagnosed as unaffected and four embryos were transferred, resulting in a twin pregnancy. Two healthy babies were delivered. Conclusion: This is the first report of successful pregnancy and delivery after specific PGD for CMT disease in Korea. Our PGD procedure could provide healthy babies to couples with a high risk of transmitting genetic diseases.

With recent spotlight on the, uniquitous computing technology, the need for object of indentification and location infrastructure has increased. Such GPS technolgy must utilize IEEE 802.15.4 Zigbee used for existing wireless sensor network infra as a basice element for user's context-awareness in a uniquitous environement, for effectiveness.Such real-time GPS service is provided in the internal environment where the user would actually are and most high-rise buildlings apply. Underthe assumption, the real-time GPS technology is seperated by each floor, and signals do not get transmitted to other floors, the application on one floor within the high-rise buildling was conducted. This study intends to suggest a floor detection algorithm using IEE 802.15.3/Zigbee's RSSI which supports the accuracy within a couple of meters for the user's the movement between the floors in high-rise buildings in a complex environment. It proposes an floor detection algorithm using IEEE 802.15.4/Zigbee's RSSI which provides accuracy within a radius of few meters for the users movement between the floors for real-time location tracking within high-rise building in a cmoplex environment. Furthermore, for more accurate real-time location tracking, it suggests an algorithm for real-time location tracking using IEEE 802.15.4a/Zigbee's CSS technology based on triangulation. Based on the suggested algorithm, it designs a hybrid real-time location tracking service system in a high-rise buildling and test its functions.

Previous experimental results performed by many researchers for a couple of decades in South Korea have shown that an absorbing sheet inserted in a conventional floating slab system for thermal insulation or vibration absorption may amplify the vibration of the slab system at specific frequency ranges depending on the material properties of the sheet. The amplified vibration, consequently, results in the heavy weight floor impact noise exceeding the sound level limit for an apartment house, 50 dB. In this study, the amplification mechanism is examined through numerical analysis and a new slab system is proposed to reduce the amplification and control the noise. The new slab system consists of studs connecting the base slab and upper concrete finishing yielding the dramatically increased stiffness of the slab. The numerical simulation is performed to investigate the effect of the slab system with studs on the vibration and noise control. The results show that the performance of the slab is sensitive to the number and location of studs, and the heavy weight floor impact noise can be reduced up to 6~7 dB compared to the conventional slab system at the optimal stud location.

This study was conducted to examine the effect of corn (Zea mays L.) - soybean (Glycine max L.) silage prepared by intercropping method on the nutritive value of the silage, in vitro rumen fermentation characteristics, dry matter degradability, as well as milk yield and milk composition of dairy cows. In a couple of experiments intercropped corn-soybean silage (CSBS) was compared with corn silage (CS) and/or Italian ryegrass hay (IRG). Numerically, CSBS had higher crude protein, ether extract, and lactic acid contents compared to CS. In vitro rumen fermentation analysis demonstrated that up to a 24-h incubation period, both CS and CSBS showed higher total gas production, ammonia N concentration, and dry matter degradability compared to IRG (p<0.05). The investigation on animals was conducted in a commercial dairy farm located in Gyeongju, South Korea, employing 42 Holstein cows that were divided into 2 group treatments: CS and CSBS in a completely randomized design. Although no significant difference was observed in milk yield, animals fed on CSBS showed significantly higher milk protein (p<0.05) and milk fat content (p<0.01), compared to animals fed on CS. Taken together, our findings indicate that corn-soybean silage that is cultivated, harvested, and prepared through intercropping can improve the protein content of the silage, and can also enhance in vitro rumen fermentation, dry matter degradability, and performance of dairy cattle.
