This paper is a descriptive study that aims to investigate attitudes towards menstruation, symptoms and coping behaviors in order to develop a program for building positive attitudes toward menstruation in primary school students. The mean age of menarche was 12.3 years, and students generally showed negative attitudes towards menstruation. Students who experienced menarche had relatively more positive attitudes than those who did not. However, no significant difference was exhibited. Menstrual symptoms occurred rarely or at a moderate level by showing a low score of 2.12 points. Of all sub-factors, 'pain' was the most serious. The most common coping behaviors during menstruation was 'I take a warm shower' and 'I take a rest or nap', while respondents rarely checked 'I take vitamin B supplements' and 'I take painkiller'. Based on the above findings, the study intends to perform a systematic study to further identify the factors affecting menstrual attitudes in primary school students. In addition, this paper suggests effective healthcare education on menstruation to build positive attitudes towards menstruation and education and counseling programs for adopting appropriate coping strategies to deal with menstrual symptoms.

This study was done to identify the factors associated with health promotion practices of hospital employees. Data was surveyed using questionnaires by 204 hospital employees in 2 general hospitals which were located in Seoul from January 11 to February 11, 2010. The results were as follows ; First,, there was significantly higher difference(F=3.802, p=0.026) in self-efficacy for health promotion practices at the groups(3.71) which reported less stress than at the groups(2.64) which reported high stress. Secondly, there was significantly higher difference(F=3.496, p=0.048) in social support at the groups which do exercise than at the groups which do not exercise. Thirdly, self-efficacy and social support were significantly positive correlation(r=0.591, p<0.001). In conclusion, it need application and development that allow for positive self-management program to improve the practices of health promotion for hospital employees.

There are developing the World Wide Web systems for their information sharing among certain closed user group. These systems are required five common functions as follows. First, they have to support the web service for Internet users to access easily. Second, Hey have to support the authorization service to confirm the allowed users. Third, they have to support the database service to manage the sharing information among users. Fourth, they have to support the bulletin board service for closed users to discuss. Fifth, they have to support the e-mail service to send e-mail to the certain user subset and mail archive service to save and manage the previous mail information. In this paper, we described the detail function and processing procedure of our implemente system under LINUX operating system. In addition, we described problems occurring in implementation and their solutions.

D-limonene included in citrus fruits is obtainable to extract essential oil as well as separate the oil ingredient. Soxhlet extraction, a type of SDE (Simultaneous steam Distillation and solvent Extraction), was used to extract limonene from tangerine peel. HPLC analysis was performed to quantify extracted d-limonene by using reversed-phase HPLC column. Results of HPLC analysis showed that the optimal extraction time was 2 hours in any solvent, and the extracted amounts of d-limonene in tangerine peel (per g tangerine peel) were 7.77 mg, 0.49 mg, and 0.28 mg in ethyl alcohol, n-hexane, and ether. Because yield was the highest in using ethyl alcohol as a solvent, polarity is stronger factor to effect on yield of extraction than boiling point.

The purpose of this study was to develop a mentoring program to support the professional growth of new nurses and to check the effectiveness. This mentoring program was developed by research teams and mentoring professionals based on Benner's theory. The data was analyzed using SPSS 18.0 program. The average of satisfaction of mentoring program in the mentees is 4.31 higher than mentor as 3.77. The highest scored item was 'need of mentoring program', the lowest one was 'mentoring program period and number of meetings'. Finally based on the results of the research, the duration of the mentoring program was changed to the six months. A steady support of the organizational policy about mentoring program is required to secure an outstanding nursing workforce.

We have observed a large increase in the magnetoresistance (MR) of Bi thin films, which were subjected to a post-annealing procedure at $268^{\circ}C$C, $3^{\circ}C$ below the Bi melting point. We have achieved an increase in the MR by 260-fold and 1200-fold at 5 K and 5 T after post-annealing, as compared with 190 and 620 for an as-deposited Bi film on PbTe/CdTe(111) and on mica, respectively. The large MR increase by post-annealing might be due to the improvement of crystallinity according to the x-ray analysis. However, post-annealing over a certain amount time showed the reduction in MR values.

The purpose of this study was to identify consciousness of bio-medical ethics of nursing and non-nursing students. The total mean scores of consciousness of bio-medical ethics between nursing(3.04/4) and non-nursing(2.88/4) were significantly different(t=6.79, p<.001). There were statistically significant differences between two groups in sub-categories of consciousness of bio-medical ethics: right to life of fetus, prenatal diagnosis of fetus, right to life of newborn, euthanasia, organ transplantation, brain death. The major predicting factors for consciousness of bio-medical ethics were experience of studying for biomedical ethics over 1 semester, experience of conflict for biomedical ethic problem, and ethical attitude in nursing department. Study results indicate that appropriate and various teaching-learning method for education of each department is deeded according to move up into a higher class with consciousness of bio-medical ethics, ability of decision making, critical thinking.

Since the advent of turbojet aircraft with their greater weight and high landing speed breaking performance on runway surface has become un critical. Under certain weather conditions(wet weather, winter) hydroplaning or unacceptable loss of traction can occur, resulting in poor braking performance and possible loss of directional control. To address this concern a number of research project me conducted by NASA, FAA, USAF. The various method which was reported the advantage of the increasing the friction and decreasing the hydroplaning effect. A-2 section of inchon international airport was grooved using drying grooving method. In order to evaluate the effectiveness of the dry grooving method the surface was spray with water and measured the fiction factor and the depth of the water using Mu meter and water depth measuring device. The field test results shooed that the fiction factor nos increased and the depth of the water decreased. The dry grooving method illustrated the reduction of hydroplaning and also, no distress on the runway.

A room-and-pillar underground structure is characterized by its grid-type array of room and pillar. As a result, its construction and economical efficiency can be governed by excavation sequence. In this study, the construction period by the drill and blast method which can be treated as a main sequence for excavation was examined by considering the regulation for blasting and construction standard of estimation in Korea. To evaluate the construction period for the room-and-pillar underground structure constructed in 4 kinds of square-type area ($30{\times}30{\sim}57{\times}57m$), the concurrent excavation pattern which was suggested in the previous researches was used. From the suggested condition, the total construction period by drill-and-blast method can be estimated with the consideration of the construction area, number of jumbo drill and faces in operation.
