Background & Objectives: The current study aims to convey correct knowledge of dementia that is be on the rise as the most significant social problem and provide basic data for implementing immediate school health education for dementia which is the basis of improving quality of life for patients with dementia, their family and the society by analyzing recognition level for dementia among male and female students in the 2nd grade of middle school and the necessity of school health education for dementia. Methods: The current study conducted a survey with a total of 150 students. 25 male and female students respectively selected from three middle school taking into account regional characteristics. The study also processed the survey results using SPSS-PC Program 12.0 and gained the following results by implementing Frequency Analysis. Cross-tabulation Analysis and ANOVA Analysis. Results: As for respect for grandparents, 55.3% of the respondents said they respect their grandparents. while 39.3% answered so-so and 5.3% said they don't respect their grandparents. As for the number of they meet grandparents, 36.0% of the respondents said they meet grandparents once or twice a month, which was the most frequent answer. On the other hand, 24.7% are once or twice every six months, 13.3% are once or twice a year and a week, respectively, and 6.7% said that they seldom meet their grandparents. In a question about whether they had recognized dementia after explaining dementia in detail, 82.7% said' yes' while 17.3% said' no'. But few students recognized it when they were asked using a terminology' dementia' first. The average score of knowledge level integrating the most fundamental 16 questions about dementia was $11.20{\pm}1.73$. Also 83.3% of the respondents answered that they had no experience in health education about dementia while 16.7% said presented positive answers. In the necessity of health education about dementia, 73.3% of them said' necessary' while 21.3% said' so-so' and 5.3% said 'not necessary. Conclusions: From the above study results, it was found that it is time to emphasize the necessity and importance of school health education for improving respect for the old and a sense of responsibility for support and converting recognition for dementia in Korea that has social structure of the trend toward the nuclear family and heads for an aged society. However, the fact that the above things are not implemented at all in reality can expand disparate views among family members in the future and further can cause even more serious problem by neglecting senior problems. Therefore, the government, social organizations, especially school organizers should recognize the necessity and importance of school health education and actively begin cultivations of students' character by implementing the education about dementia at the early stage.

Objectives : The purpose of this study is to compare the effects of Sweet Bee Venom Pharmacopuncture and Scolopendrid Pharmacopuncture on Carpal Tunnel Syndrome. Methods : From February to September 2010, the number of patients with Carpal Tunnel Syndrome who volunteered for this clinical study was 16 and 7 out of 16 patients complained both hands. Total 23 cases of hands were randomly divided by 2 groups. We injected Sweet Bee Venom Pharmacopuncture on PC7(Daereung) twice a week for 4weeks for experimental group(n=11), and Scolopendrid Pharmacopuncture with the same methods for control group(n=12). One case was dropped out due to itchiness of allergic response in the experimental group. Improvement of the symptoms was evaluated by Visual Analogue Scale, Pain Rating Scale, Tinel's sign, Phalen's sign and Nerve Conduction Velocity. Nerve Conduction Velocity was checked at baseline and the end of the trial and others were checked at baseline, after 2 and 4 weeks. Results : Both groups showed significant improvement in Visual Analogue Scale, Pain Rating Scale, but no significant difference between two groups. Only the control group showed significant reduction of the 'poitive response' in the Tinel's sign and Phalen's sign. However, no groups improved in Nerve Conduction Velocity. Conclusions : These results showed that Sweet Bee Venom Pharmacopuncture and Scolopendrid Pharmacopuncture could decrease the symptoms of Carpal Tunnel Syndrome. Further studies will be required to examine more cases for the long period and use more various concentration and amount pharmacopuncture for the effect on Carpal Tunnel Syndrome.

The purpose of this study was to identify the stressors and coping behaviors among the 5th 6th graders at Gwangju city. The subjects were 352 elementary school students and the data were collected by self-reported questionnaire from June 19 to July 21, 2003. Study instrument to investigate stressors was developed 40-items summated scale (${\alpha}$ = .87) with four subcategories: 8-items individualistic (${\alpha}$ = .72), ll-items family life-related (${\alpha}$= .70), 14-items school life-related (${\alpha}$= .76) and 7 socio-environmental (${\alpha}$= .63) factors. And the instrument to examine stress coping behaviors was also developed 30-items summated scale (${\alpha}$= .82) with three subcategories: 10-items active (${\alpha}$= .72), 10-passive (${\alpha}$= .75), and 10-mystic (${\alpha}$ = .70) coping behaviors. The data were analyzed by descriptive statistics, t-test and ANOVA using SPSS/PC+ program. The results were summarized as follows: Mean score of stressors was $66.6{\pm}14.45$ out of 160. There were no significant differences in total scores of stressors in terms of gender, grade, number of siblings and the school location The score of individualistic stressors, on the other hand, was tended to be significant higher in the 6th graders (t = -2.155, p = .032) and the school children in Gwangsangu district where has mixed rural and urban characteristics (F = 2.400, p = .049). Mean score of stress coping behaviors was $61.3{\pm}12.24$ out of 120. It was significantly different in terms of number of siblings (t = 2.108, p = .036) and the school location (F = 4.928, p = .001). In several subcategories, the mean scores of active coping behaviors were significantly higher in the only children group (t = -2.127, p = .034) and Donggu district where traditional downtown area (F = 2.410, p = .050). and passive (F = 4.013, p = .003) and mystic coping (F = 2.720, p= .030) were also significantly higher in the same district. In conclusion, the score of stressors of children in Gwangju city showed relatively low as that of other areas, and the children utilized active coping behaviors more frequently in various stressful situations.

Studies are needed to determine the standard norms for sleep/activity patterns in new born baby and there have been no established reports of discrepancy of sleep/activity patterns in new born baby among various races. The purpose of this study is to determine whether the NCASA(Nursing Child Assessment Sleep Activity Record) would be suitable to evaluate and to provide the basic resources for a Korean model of sleep/activity patterns during the new born baby, and to provide a basis for nursing intervention for mothers of new born baby. The subjects of this study were 38 normal new born baby who visited the postpartum care center and two general hospitals located in pusan from January 1 to April 28, 2000. They all agreed to participate in this study. The method of data collection was through convenient sampling. Data were collected through questionnaires including demographic data, birth hi story, and general informations concerning the infant, mother and family. The instrument of this study was the NCASA translated by the Korean parent Child Health Academic Association. The collected data were analysed by mean. standard deviation, frequency, and percentage by use of SPSS/PC. The conclusions obtained from this study are summarized as follows: 1. The mean amount of daytime sleep was 10.23 hours. The mean amount of nighttime sleep was 5.53 hours. The mean amount of total daily sleep was 15.77 hours. The mean of the longest sleep period was 4.49 hours. The mean regularity of daytime sleep was 49.69%. The mean regularity of nighttime sleep was 66.98%. The mean regularity of total daily sleep was 55.81%. The mean frequency of nighttime wakenings was 3.09 times. 2. The mean amount of daytime awake periods was 6.12 hours. The mean amount of nighttime awake periods was 2.11 hours. The mean amount of daily total awake periods was 8.23 hours. The mean of the longest awake periods was 3.76 hours. 3. The mean frequency of daytime feeding was 5.71 times. The mean frequency of nighttime feeding was 2.65 times. The mean frequency of total daily feeding was 8.36 times. The mean frequency regularity of feeding was 62.50%. 4. The mean amount of a mother's day time was 16.36 hours. The mean amount of a mother's night time was 7.64 hours. In conclusion, The new born baby slept more during the daytime compare than nighttime and more active during the daytime. On the other hand. although nighttime sleeping the length of the mother was normal, but sleep was interrupted by the infant over 3 times on average. Therefore this research study will contribute to nursing practice and nursing research by its implication through postnatal educational nursing programs at hospital and nursing intervention programs that would help individual caring of early infant mothers at home.

To analyze human thermal environments in protected horticultural houses (plastic houses), human thermal sensations estimated using measured microclimatic data (air temperature, humidity, wind speed, and solar and terrestrial radiation) were compared between an outdoor area and two indoor plastic houses, a polyethylene (PE) house and a polycarbonate (PC) house. Measurements were carried out during the daytime in autumn, a transient season that exhibits human thermal environments ranging from neutral to very hot. The mean air temperature and absolute humidity of the houses were $14.6-16.8^{\circ}C$ (max. 22. $3^{\circ}C$) and $7.0-12.0g{\cdot}m^{-3}$ higher than those of the outdoor area, respectively. Solar (K) and terrestrial (L) radiation were compared directionally from the sky hemisphere (${\downarrow}$) and the ground hemisphere (${\uparrow}$). The mean $K{\downarrow}$ and $K{\uparrow}$ values for the houses were respectively $232.5-367.8W{\cdot}m^{-2}$ and $44.9-55.7W;{\cdot}m^{-2}$ lower than those in the outdoor area; the mean $L{\downarrow}$ and $L{\uparrow}$ values were respectively $150.4-182.3W{\cdot}m^{-2}$ and $30.5-33.9W{\cdot}m^{-2}$ higher than those in the outdoor area. Thus, L was revealed to be more influential on the greenhouse effect in the houses than K. Consequently, mean radiant temperature in the houses was higher than the outdoor area during the daytime from 10:45 to 14:15. As a result, mean human thermal sensation values in the PMV, PET, and UTCI of the houses were respectively $3.2-3.4^{\circ}C$ (max. $4.7^{\circ}C$), $15.2-16.4^{\circ}C$ (max. $23.7^{\circ}C$) and $13.6-15.4^{\circ}C$ (max. $22.3^{\circ}C$) higher than those in the outdoor area. The heat stress levels that were influenced by human thermal sensation were much higher in the houses (between hot and very hot) than in the outdoor (between neutral and warm). Further, the microclimatic component that most affected the human thermal sensation in the houses was air temperature that was primarily influenced by $L{\downarrow}$. Therefore, workers in the plastic houses could experience strong heat stresses, equal to hot or higher, when air temperature rose over $22^{\circ}C$ on clear autumn days.

Object : Objective: This study was conducted to investigate the anti-cancer effects of Mylabris phalerata (반모) in some kinds of cancer cells. Materials and Methods: Some kinds of cancer cells lines were treated. We used nine kinds of cancer cell lines, such as stomach cancer cells (Kato), lung cancer cells (Calu-1, NCI-H 1395), urinary bladder cancer cells (HS789T), bone cancer cells (Saos-2), brain cancer cells (SK-N-MC), liver cancer cells (Hep-G2), skin cancer cells (Mo-1) and prostate cancer cells (PC-3) with the water decoction of Mylabris phalerata. The histological changes of all cell lines in the media (RPMI-1640) containing the decoction of Mylabris phalerata were observed and we examined cell death assay by trypan blue exclusion testing was examined. Finally, the change of mitochondrial membrane potential was measurd and the inhibitory effect of Mylabris phalerata on cell increase was examined by analyzing the cell cycle. Results: In histologic change all cancer cell lines showed withdrawn and floating appearance that is typical in cellular impairment. Most of the cell lines showed over 50% death rate after 24 hours in trypan blue exclusion tests. Especially the stomach, urinary bladder. brain and liver cell lines showed over 30% death rate after 12 hours. All cell lines treated with Mylabris phalerata were less stained than the control group and the mitochondrial membrane potential in the Mylabris phalerata treated cell lines was markedly lower than that in the control group. The measurement of DNA quantity in all cell lines showed the disappearance of the peak and the thickened left axis, which suggests that all cellular DNA degraded. Conclusion: Mylabris phalerata had cytotoxicity on various kinds of cancer cell lines and the mechanism of that was the impairment of mitochondria by the breakdown of the mitochondrial cell membrane. We propose that this is in part attributable to the destruction of DNA in cancer cells.

Objectives: In this study, knowledge of environmental disease, experience of environmental health education and necessity of environmental health education of elementary school pupils were compared and analyzed. Methods: The population of this study was from grade 1 to 6 elementary school pupils in Ulsan city, Korea. Five elementary schools were randomly selected from Ulsan City. Seven hundred and twenty-eight responses from the five schools were analyzed (seventy-two were excluded). A self-administered questionnaire measuring sociodemographic variables, Knowledge of environment related disease(atopic dermatitis, asthma etc), as well as educational experience and necessity of environmental health education was analyzed. The survey results were analyzed using SPSS-PC Program 12.0 and the following results by implementing Frequency Analysis, Cross-tabulation Analysis and ANOVA are as follows. Result: Pupils of lower grades more informed than those of higher grades about atopic dermatitis. Among asthma sufferers, many responded that symptoms occurred or improved during the lower grades of elementary school. In terms of the lifestyles of patients with atopic dermatitis or asthma, female pupils, especially those in the lower grades, tended to make changes in their daily habits based on their disease. Also, parents tended to intervene/mediate more in the dietary habits and personal hygiene habits of lower-grade pupils compared to their higher-grade counterparts. Personal hygiene education is currently not provided in schools, and upper-grade pupils have more experience with personal hygiene education compared to lower grade pupils. 430 (59.0%) of pupils replied that education about personal hygiene is necessary in their curriculum. 490 (67.3%) of elementary pupils are aware of the close connection between education in hygiene and human health. When asked if education in hygiene should also be undertaken by teachers and parents, 406 (55.7%) students said that it should be done. Conclusions: Developing a concrete health education program and raising instructors' awareness of the necessity for education in hygiene. Placement of professionals in the personal hygiene education field, is important to provide good health education for elementary school pupils.

The purpose of this study was to investigate the prevalence, relative factor and the effects that overactive bladder or urinary incontinence have on women's lives. Data was gathered through an internet survey. The subjects included 3,372 women ranging from 20 years old to 49 years of age. The questionnaire included general characteristics (age, parity, family history, and history of UTI), overactive bladder symptoms (urgency, frequency, nocturia, urgent incontinence), urinary incontinence, discomfort in ADL and sexual activity. The data was analyzed by the SPSS/PC+ program using frequency, $x^2$ test, and multivariate logistic regression. The results were as follows; 1. The prevalence was 12.7 % in overactive bladder and 21.0% in urinary incontinence. 2. 19.2% of the subject have urge incontinence, 5% of them have coped with the use of a pad. 3. The significant factors to overactive bladder were age($x^2$=6.6, p<0.05), history of urinary tract infection ($x^2$=50.8, p<0.01) and family history ($x^2$=26.1, p<0.01). The significant factors to urinary incontinence were age ($x^2$=6.2, p<0.05), occupation ($x^2$=11.0, p<0.05), history of urinary tract infection($x^2$=20.2, p<0.01), parity ($x^2$=8.6, p<0.01), and family history ($x^2$=4.9, p<0.05). 4. Overactive bladder impacts on individual daily life was 5.0 times, urinary incontinence was 2.9 times higher than in non-symptoms. Also, overactive bladder impacts on their sexual activity disturbance was 4.3 times, urinary incontinence has 3.9 times higher than in non-symptoms. In conclusion, overactive bladder symptoms and urinary incontinence were health problems that disturbed women's lives. Also the most problem among overactive bladder may be urgency in Korean. Intervention based on these results needs to be provided for these women.
