The purpose of this study was to develop prevention and educational programs for battered women. The first stage was to assess battered women's health status and health needs. The second stage was to develop prevention and educational programs to improve battered women's health. A survey research design was used to gather data from June-November 1999 by the counselor. Research sample was recruited from shelter and women's counseling centers in Seoul, Inchon, Chooncheon, Taejeon, and Jeoju. Trained counselors contacted 218 women, who agreed verbally to participate in the study. The researcher did a literature review and developed the tool used. We did ten pretests and three counselors checked the tool for content validity. The reliability and validity of the instrument were acceptable. The second stage of the research consisted of lay-professional groups discussing the abuse problems and possible solutions. Each group had five professionals (counsellor, nurse, minister, psychiatrist, social worker) and five women who have experienced battering from her husband in community. Result of the survey and two(lay persons and professionals) group discussions showed that victims need more assessment of physical, mental and spiritual needs. Victims were beaten more often during their pregnancies than at other times. Various kind of strategy were frequently utilized, but still the number of women abused and suicides committed increased. Both studies showed that the women experienced severe beating, that they felt powerless, that they need to understand that society abuser characteristics, that they lack a protection support system and that society lacks would an understanding of battered women. Based on the result of both studies, we developed model for prevention and education of battered women. This educational program will increase women s power to solve the abuse problems. The ultimate goal of the program is to develop a one-stop center to give wholistic approach care to women in abuse situations.

This paper presents experimental research work for the evaluation of ultimate flexural behaviors of prestressed concrete beams with a corroded tendon. In order to evaluate the effects of loss of prestress or loss of tendon area on the ultimate flexural strength of prestressed concrete beams, static load tests are conducted using five prestressed concrete beams. After exposing prestressing tendons in two test beams using 25mm drill bit, the exposed tendons were corroded using an accelerating corrosion equipment to simulate loss of tendon area. During the tests, steel strains, concrete strains and displacements at the center of test beams were measured, and acoustic emission measurements were conducted to detect wire fractures. Based on the test results, evaluation method for predicting flexural strength of prestressed concrete beams with corroded tendons is investigated. In addition, evaluation methods for predicting the existence of corroded tendons in post-tensioned prestressed concrete beams at service loads are discussed.

In fish both humoral and cell mediated immune responses have been reported whereas antibodies recognizing specific cellular populations have not yet been developed except for ones recognizing surface Ig molecules on B lymphocytes. Our aim was to develop and characterize monoclonal antibodies (Mabs) specific for the immune-related cells. Mabs were produced by fusion of myeloma cells (SP2/0) with Balb/c mouse spleen cells previously sensitized against Israeli carp (I. carp) kidney mononuclear cells. We obtained 44 Mabs positively reacting with I. carp kidney mononuclear cells and partially characterized 7 Mabs in the morphological and mitogen-based proliferative aspects. Fluorescence-activated cell sorter (FACS) analysis against I. carp kidney cells by using 7 different Mabs showed 80.3% for ICK 17-4, 65.1% for ICK 2-3, 64.1% for ICK 25-1, 67.5% for lCK 22-1, 70.8% for ICK 16-2, 76.8% for ICK 13-2, 79.7% for ICK II-I. Panning method was used for the isolation of Mabs specific mononuclear carp spleen cells followed by Wright's stain. The stained cell populations were identified as monocytes (ICK 17-4, ICK 2-3, ICK 25-1, ICK 22-1 and ICK 16-2), lymphocytes (ICK 11-1), and a mixed cell population of monocytes and lymphocytes (ICK 13-2). In cell proliferation assay, monocytes purified by ICK 17-4, 2-3 and 22-1 efficiently responded to Con A and PHA, while ones separated by ICK 25-1 did not react with any mitogens. Lymphocytes isolated by ICK 11-1, though it is not known whether they are T or B cells, were more responsive to Con A than PHA or LPS, suggesting that fish immune cells are somewhat different from mammalian cells in responding to mammalian T or B cell mitogens.

Purpose: This study aimed to identify depression and its predictors among Korean community-dwelling elderly with mild cognitive impairment. Methods: Secondary data analyses of the data collected by the "Study on tailored integration program for reinforcing cognitive and physical function of the frail elderly. The study used data from one-to-one interviews using structured questionnaires. The subjects were 346 community-dwelling elderly who visited a healthcare center in Seoul, Korea. A descriptive correlational study design was utilized to explore depression and its predictors including physical factors and psychosocial factors among the elderly with mild cognitive impairment. Data were analyzed using t-test, Pearson's correlation, and hierarchical regression. Results: Mean score of depression was within normal limit $11.61{\pm}6.69$. Somatic symptoms, negative life events (severity), social support were shown as significant predictors of depression. The most influential predictor for depression was somatic symptoms (${\beta}$=.340, $p$ <.001). Conclusion: To prevent and relieve depression in the elderly with mild cognitive impairment, nursing intervention strategies which consider well-balanced physical and psychosocial aspects are needed. In particular, a specific nursing intervention strategy is required to improve physical health of the elderly with mild cognitive impairment.

This study was to investigate the effects of music-combined respiration and oral motor training on the voice of healthy elderly. 27 women attending a senior center in Seoul participated and were randomly assigned to the experimental (n = 16) and the control group (n = 11). Subjects attended music program(25 minutes per session) once a week for 4 weeks. For both groups, Fundamental Frequency (F0), Maximum Phonation Time (MPT) and Sequential Motion Rates (SMR) were measured using the Praat speech analysis program before and after the training. The results showed statistical significance in scores of intensity, F0, MPT, and SMR in the experimental group while only intensity was statistically significant in the control group. Considering that, the increasing life expectancy and growing number of older adults, their quality of life has been important. So this study suggests that the respiration and oral motor training would be effectively incorporated into training and services for this population.

The purposes of this study were (1) to explore the gender differences in children's overt aggression and relational aggression and (2) to investigate the effects of preschool children's gender, temperament, emotional regulation, and maternal parenting stress on overt aggression and relational aggression. The participants were 173 preschool children and their mothers from three day care center and two kindergarten in Seoul and Gyeong-gi province. The data were analyzed using descriptive statistics, t-test, correlations, and multiple regressions. The results were as follows: (1) There was statistically significant gender difference in preschool children's overt aggression, but there was statistically no significant gender difference in preschool children's relational aggression. Boys displayed more overt aggression than girls. (2) Preschool children's emotional regulation and activity explained children's overt aggression and relational aggression. When preschool children expressed more emotional regulation, they showed less overt aggression and relational aggression. Preschool children, who perceived having more activity from mothers, diaplayed more overt aggression and relational aggression. Gender was found to affect preschool children's overt aggression.

Purpose: This study was designed to identify factors affecting depression among hospitalized older adults prior to discharge from an acute care hospital. Methods: This descriptive study included adults aged 65 or older who were hospitalized in a general hospital in Seoul, Korea. Depression was measured by the Short Form Geriatric Depression Scale and illness perception was evaluated by the Brief Illness Perception Questionnaire. Social support was examined using the Perceived Geriatric Social Support Scale. Data were collected from August 25 to October 12, 2015. Data analysis included descriptive statistics, independent t-test, Kruskal-Wallis test, Pearson's correlation coefficient, and hierarchical multiple regression. Results: Among a total of 120 participants, 57 patients (47.5%) experienced depression. Mean depression score was $7.37{\pm}3.67$. Depression was associated with illness perception (r=.53, p<.001), social support (r=-.19, p=.043), number of admission due to the recurrence (r=.31, p=.001), and time to recognize discharge plan (r=.25, p=.044). In hierarchical multiple regression, illness perception (${\beta}=.45$, p<.001) and time to recognize discharge plan (${\beta}=.21$, p=.039) were predictors of depression (F=7.68, p<.001, Adjusted $R^2=.38$). Conclusion: The findings of this study suggest that management of illness perception and timely notice of discharge are important to reduce depression in hospitalized elderly patients.

Purpose. Tai Chi exercise, an ancient Chinese martial art, has drawn more and more attention for its health benefits. The purpose of the study was to identify the effects of a Sun-style Tai Chi exercise on arthritic symptoms (joint pain and stiffness), motivation for performing health behaviors, and the performance of health behaviors among older women with osteoarthritis. Methods. Total of 72 women with the mean age of 63 years old were recruited from outpatients clinic or public health centers according to the inclusion criteria and assigned randomly to either the Tai Chi exercise group or the control. A Sun-style Tai Chi exercise has been provided three times a week for the first two weeks, and then once a week for another 10 weeks. In 12 weeks of study period, 22 subjects in the Tai Chi exercise group and 21 subjects in the control group completed the posttest measure with the dropout rate of 41 %. Outcome variables included arthritic symptoms measured by K-WOMAC, motivation for health behavior, and health behaviors. Results. At the completion of the 12 week Tai Chi exercise, the Tai Chi group perceived significantly less joint pain (t = -2.19, P = 0.03) and stiffness (t = -2.24, P = 0.03), perceived more health benefits (t = 2.67, P = 0.01), and performed better health behaviors (t = 2.35, P = 0.02), specifically for diet behavior (t = 2.06, P = 0.04) and stress management (t = 2.97, P = 0.005). Conclusion. A Sun-style Tai Chi exercise was found as beneficial for women with osteoarthritis to reduce their perceived arthritic symptoms, improve their perception of health benefits to perform better health behaviors.

The purpose of this study was to document the histology of canine acupoints. Acupunctural needles were inserted by 0.5 to 1 cm depth into acupoints Nei-guan (Inner pass, PC06), Gan-shu (Liver Association Point, BL18), Shen-shu (Kidney Association Point, BL23) and Pangguang-shu (Bladder Association Point, BL28) in 4 dogs, and the tissues around the acupoints were examined. Light microscopy was used to observe the surrounding structures of each point. Nerve fibres, small vessels and muscle spindles were found around the tip of the needle in every case, although they occurred not so often at nonacupoint in nearby region or nonacupoint in the areas, such as skin, subcutaneous tissue and muscle. Therefore, it is suggested that nerve fibres, small vessels and muscle spindles may be potential acupoint receptors.

Studies were carried out on the selective removal of inorganic salts such as NaCl and $Na_2SO_4$ from dye solution, using counter diffusion-reverse osmosis and nanofiltration, respectivey. For the dye solution used in the experiments, 1 to 30% of salts were removed by counter diffusion while the loss of dye molecules was less than 0.3%. The separation factors by one pass operation were 10-500 according to ionic species. In five successive operations, removals of anion($Cl^-$) increased but those of cation($Na^+$) decreased due to the Donnan effect. Effects of feed flow rate on removal efficiencies of various ions were also observed at constant flow rate of stripping water. Reverse osmosis of desalted dye solution by counter diffusion was conducted to prepare highly concentrated liquid dyes. The rejection efficiency of dye molecules was greater than 99%. For the rejection efficiency of chloride ion, experimental values were compared with theoretical ones based on solution-diffusion model. Two stage diafiltration was performed in nanofiltration. The rejection efficiency of chloride ion was continuously decreased due to the Donnan dialysis and even negative rejection was observed. The Donnan effect was more pronounced in the second diafiltration.
