Caring has been identified as the essence and unifying domin of nursing(Leininger). Many nurses believe that the art of nursing is comprised of actions that are predominantly caring in nature. Although caring has been the traditional ideology of nurses, it is only now beginning to emerge as the central construct for the development of nut sing research, theory and practice. The problem addressed by this study was to identify how hospitalized children and their nurses express the meaning of caring, how they think nurses should care for children and to describe their experiences of being cared for. The purpose was to provide theoretical understanding of caring as perceived in Korea to contribute to the development of Korean nursing knowledge. The subjects were 76 hospitalized children admitted to pediatric units in five teaching hospitals and 66 nurses who were caring for these children. In this descriptive study, data were collected from Nov 11, 1991 to Jan 30, 1992 by interviews and an open-ended questionnaire and analysed by van Kaam's method. Caring themes perceived by the children and their nurses were classified into eight categories, -helping, comfort, love, warmth(only by children), recovery from illness, health maintenance (only by nurses), presence, nurturance and responsibility. Ideal caring behaviors perceived by the children and their nurses were six categories, -to give help, provide comfort, give love, stay with, treat warmly and aid recovery. Subcategories of giving help were promptness and competence, detailed explanations and support and encouragement. Other subcategories of giving help reported only by nurses were individualizing care, recognizing needs and providing a familiar enviornment. Subcategories of maintaining comfort were making comfortable, alleviating pain ; one subcategory reported only by children was consolating. A subcategory of giving love was concern, two subcategories reported only by nurses were compassion and respect. Subcategories of staying with were playing with and touching : only nurses reported empathy, Subcategories of treating warmly were tenderness and kindness. In the experience of caring, there were 4 categories, -to give help, stay with, show concern and provide comfort. Both the hospitalized children and their nurses had experienced caring primarily from their mothers. Mothers' caring behaviors were direct, personal, basic, supportive nursing acts. On the other hand, nurses caring behaviors were task oriented skilled procedures and medically delegated acts. This study contributes understanding of the complexity of caring, more specifically the meaning and experience of caring and ideal caring behaviors. Research may be able to move into verification when instruments are developed to measure the complexity of caring beliefs, values and behaviors in Korea and other cultural settings.

This study was aimed to identify the effect of abdominal moxibustion on premenstrual syndrome and dysmenorrhea in university students. The data were collected by using questionnaires from April 25, 2005 to June 20, 2005. The subjects were university students from in the Pusan metropolitan area who had complained of menstrual discomfort. Thirteen students were assigned to the experimental group and fourteen students to the control group. The research design of this study was a nonequivalent control group pretest-posttest design. In the research method pretest were conducted through measurement based on scores of general character, menstrual character, premenstrual syndrome and dysmenorrhea in the experimental group and the control group. Experimentation was conducted by abdominal moxibustion being applied on the kwan-won hole and Ki-hae hole for 25 minutes at a time, three times a week, form the ending of one menstrual cycle to the beginning of the next menstrual cycle were in the experimental group. After treatment was finished, post tests conducted through measurement based on scores of premenstrual syndrome and dysmenorrhea in the experimental group. The control group conducted a point of same time and same measurement with the experimental group. The instruments used in this study MDQ(Menstual Distress Questionnaire) developed by moos(1968) and the VAS(Visual Analogue Scale) developed by Cline(1992). The data were analysed by SPSS/ win 12.0 program with ${\chi}$2-test and t-test to verify identification among subjects' general characteristics and menstrual characteristics. Hypothesis verification was analysed with t-test. The results of the study are as follows: The hypothesis, 'the experimental group who received abdominal moxibustion will decrease premenstrual symptoms more than the control group', was supported (t= -2.121, p=.022). The hypothesis, 'the experimental group who received adbominal moxibustion will decrease dysmenorrhea compared to the control group', was supported (t=-4.424, p=.001). As a result of this study, abdominal moxibustion will be used as a nursing aide to improve and prevent menstrual discomfort of university students who have premenstrual syndrome and dysmenorrhea.

Recently, the Sub-Committee on SDC (Ship Design and Construction) of IMO have discussed actively the technical issues associated with the second-generation intact stability criteria of ships. Generally, second generation intact stability criteria refer to vulnerability five modes ship stability which occurs when the ship navigating in rough seas. As waves passes the ship, dynamic roll motion phenomenon will affect ship stability that may lead to capsizing. Multi-tiered approach for second generation of intact stability criteria of IMO instruments covers apply for all ships. Each ship is checked for vulnerability to pure loss of stability, parametric roll, and broaching/surf-riding phenomena using L1(level 1) vulnerability criteria. If a possible vulnerability is detected, then the L2(level 2) criteria is used, followed by direct stability assessment, if necessary. In this study, we propose a new method to verify the criteria of the surf-riding/broaching mode of small ships. In case, L1 vulnerability criteria is not satisfied based on the relatively simple calculation using the Froude number, we presented the calculation code for the L2 criteria considering the hydrodynamics in waves to perform the more complicated calculation. Then the vulnerability criteria were reviewed based on the data for a given ship. The value of C, which is the probability of the vulnerability criteria for surf-riding/broaching, was calculated. The criteria value C is considered in new approach method using the Froude-Krylov force and the diffraction force. The result shows lower values when considering both the Froude-rylov force and the diffraction force than with only the Froude-Krylov force was considered. This difference means that when dynamic roll motion of ship, more exact wave force needs considered for second generation intact stability criteria This result will contribute to basic ship design process according to the IMO Second-Generation Intact Stability Criteria.

The characterization of detectors installed in space- and ground-based instruments is important to evaluate the system performance. We report the development of a detector performance test system for astronomical applications using the Andor iKon M CCD camera. The performance test system consists of a light source, monochromator, integrating sphere, and power meters. We adopted the Czerny-Tuner monochromator with three ruled gratings and one mirror, which covers a spectral range of 200-9,000 nm with a spectral resolution of ~1 nm in the visible region. Various detector characteristics, such as the quantum efficiency, sensitivity, and noise, can be measured in wide wavelength ranges from the visible to mid-infrared regions. We evaluated the Korea Astronomy and Space Science Institute (KASI) detector performance test system by using the performance verification of the Andor iKon-M CCD camera. The test procedure includes measurements of the conversion gain ($2.86e^-/ADU$), full well capacity ($130K\;e^-$), nonlinearity, and pixel defects. We also estimated the read noise, dark current, and quantum efficiency as a function of the temperature. The lowest measured read noise is $12e^-$. The dark current at 223 K was determined to be $7e^-/s/pix$ and its doubling temperature is $5.3^{\circ}C{\pm}0.2^{\circ}C$ at an activation energy of 0.6 eV. The maximum quantum efficiency at 223 K was estimated to be $93%{\pm}2%$. We proved that the quantum efficiency is sensitive to the operating temperature. It varies up to 5 % in the visible region, while the variation increases to 30 % in the near-infrared region. Based on the comparison of our results with the test report by the vendor, we conclude that our performance test results are consistent with those from the vendor considering the test environment. We also confirmed that the KASI detector performance test system is reliable and our measurement method and analysis are accurate.

The goal of modern nursing is to provide comprehensive nursing care to patients. If comprehensive nursing care to children (within the hospital setting) is to be provided, consideration of the stage of growth and development of the child is especially important. From clinical observation, it appeared that nurses often disregarded individual requirements of children in giving nursing care. Therefore, the purpose of this study is to show that comprehensive nursing care which is based on an understanding of the growth and development of the child contributes to both the child and the mother's adaptability to the child's hospitalization. Method: Sixty children, three to three year of age, hospitalized at the Yonsei University Pediatric Ward ware studied. From April 1, 1973 to May 5, 1973, children admitted to the hospital were assigned to either an experimental or a compare groups. There were 30 children in each group. The sex and age of the children in each group was similar. In both groups were more male than female children. In the experimental group, each mother stayed with hot child continuously during his hospitalization. In the compare groups, the mother or some other member of the family stayed with the child. Each day on the child's admission the investigator visited the ward from 1-2 P.M. to 9-10 P.M., in order to provide comprehensive care for the experimental -group. The assistance given the nurses by the investigator was in the form of conferences regarding care and in giving direct care to the child and his mother. The compare group of children received nursing care as usually provided by the hospital. The instruments used to obtain the data for analysis were as follows: 1. The fear and anxiety reaction of the child was recorded by observation of the investigator for four areas: 1) separation from parent and relatives 2) reaction to Doctor and Nurse with white gowns 3) reaction to nursing care 4) reaction to injection and tests, etc. 2. Regression in area of eating, sleeping, and elimination were recorded by the investigator by questioning the mother and by observation. 3. Adaptability to the hospitalization was recorded by direct questioning of the children for areas of emotional and social adjustment. For children older than 3 years of age or children not seriously ill, using the simple I. Q. test this was possible for only 35 of the total 60 children. Result: 1. 55 percents of the total 60 children had been prepared by their parents for hospitalization. The children who had received prior preparation accepted hospitalization more readily than those who had received no preparation. (χ²=4.6 Ρ<0.05) 2. On admission 31.7 percent of the children expressed verbal fear of their discase or treatment. 25 percent felt that the disease was due to their mistake. 3. There was a significant difference in the reaction of the child to separation from the parent or relatives between the two groups. The experimental groups showed less anxiety due to separation than the compare group. (χ²=4.34 Ρ<0.05) In both groups there was less anxiety due to separation among school age (6-12 years) children than among preschool age (3-5 years) children. (χ²=9.22 Ρ<0.05) 4. More than half of the children in both groups reacted with fear and avoidance to doctor and/or nurses wearing white gowns. (χ²=0.06 Ρ<0.05) 5. The experimental group reacted more favorably to nursing in general than the compare group. (χ²=4.8 Ρ<0.05) 6. There was no difference in the fear and refused reaction to special tests and/or such as X-rays and injections, etc. between the groups. (χ²=3.77 Ρ<0.05) 7. More children in the compare group showed regressive tendencies in eating, sleeping, and elimination habits than in experimental groups. (χ²=2.3 Ρ<0.05 χ²=3.88 Ρ<0.05 χ²=4.9 Ρ<0.05) 8. There was a significant difference in the adaptability to hospitalization between the two groups. The experimental groups adapted more readily. (χ²=2.02 Ρ<0.05) 9. For children who had higher I.Q. s the adaptability to hospitalization was better regardless of the group. (χ²=5.03 Ρ<0.05) However, because of the small number of cases (60), this finding cannot be extrapolated without further verification. The date demonstrates that there was a greater adaptability to hospitalization by the child when comprehensive nursing care was given. By planning care and applying knowledge of growth and development to meet, nurses are in a position to prevent some of the psychological trauma associated with hospitalization.
