As a product of poverty, health means the physical, mental and social instability caused by poverty. High mortality, high morbidity, and unsatisfied needs for medical care indicate the health condition of poor people. These indicators are related to the social and psychological property. This study is to develop an effective method of nursing in the poor family which is an essential unit in the nursing field of the community and to which a fundamental approach is need as a top priority. We can make such a study, though partially, by revealing the relationship among the Health-value, Health Locus of Contol, and the Level of Self esteem. We randomly sampled 243 women who are participating in the nursing department of the comnnity nursing centers in Seoul. We investigated by using questionaries and made an analysis on the result by SAS program. The result of this investigation can summarized as follows : 1. The average age of the subjects investigated is 43.4 and the participation rate in the economic activity is as high as 49.4%. Most of them are paid daily. The average members of the family are 4.28 persons, and 80.2% of which are nuclear families. The type of housing is as follows:51.4% are monthly-rent houses. Rent houses represent 23.5%. And 43.6% of the subjects graduate the high schools 2. The level of self-esteem possessed by the subjects is 37.17. The quality of task performance(3.46) and the morality(3.53) are low as compared with the other qualities. 3. In relation to the locus of control, internality is 22.39, the influence of powerrful others represents 20.24, and the effect of chance occurance is 16.41. 4. The orderings of value scale are the physical and mental health, comfortable life, happiness, mental peace, and pleasure. The lowest order is social recognition. 5. Considering in relation to the self-esteem and the locus of control, we found out that there is a negative relationship among the self-esteem, the influence of powerful others. The lower the level of self-esteem is, the higher the influence of powerful others is. There is also a negative relationship among the detailed items such as the qualities, and the positive attitude. 6. In a significant test in the general characters of the subjects and in the level of self-esteem, we can obtain the follwing results. The higher the economic level is, the higher the level of self-esteem is. And the higher the level of satisfaction with life is, the higher the level of self-esteem is. 7. In the locus of control, the higher the economic level is, the higher the internality is. 8. In the health-level, 75.72% represent the high health -level. And the group which has the low satisfaction with life represents the high level of health-value(81.6%). With these results, we can conclude that the level of self-esteem possessed by the poor women living in the city is high and that they have the multi-dimemsional health-value even though they are living in the poor condtions. Traditionally, the poverty has been recognized as an unfavorale factor in the health care. But this study shows that the poverty is no longer an unfavorale factor and, on the contrary, it has a potential power with which people can improve their health by possessing the high self-esteem and the high health value. The ultimate purpose which the nursing task of the community has is to make the patients keep and improve their own health. So, when the nurses approach the poor patients, the nurses should put an emphasis on the individual responsibilities of the patients, and respect their own health value.

Purpose: Childhood obesity is an increasing public health issue worldwide. We examined dietary patterns among adolescents in a dormitory school, identified obese adolescents and tried to intervene to improve food habits and physical activity. Methods: We conducted an experimental prospective longitudinal study based on 36 obese (body mass index $[BMI]{\geq}95th$ percentile) adolescents (aged 12-18 years) compared with controls (healthy children: normal age-appropriate BMI ($BMI{\leq}85th$ percentile). Six months' intervention included lifestyle-modification counseling (once a week by a clinical dietician), and an exercise regimen twice a week, 60 minutes each time, instructed by a professional pediatric trainer). Both groups underwent baseline measurements at the beginning of the study and 6 months later (arterial stiffness, blood pressure, pulse, weight and height, hemoglobin, creatinine, liver enzymes, highly sensitive C-reactive protein and complete lipid profile). Results: Twenty-one participants completed the study. Low compliance from participants, school staff and parents was observed (participation in planned meetings; 71%-83%). BMI significantly decreased from $32.46{\pm}3.93kg/m^2$ to $30.32{\pm}3.4kg/m^2$ (P=0.002) in the study group. Arterial stiffness was not significantly different between the 2 groups and did not change significantly after 6 months' intervention (P=0.494). No significant changes in CRP and lipid profile were observed after the intervention. Conclusion: Making lifestyle modifications among adolescents in a dormitory school is a complex task. Active intervention indeed ameliorates BMI parameters. However, in order to maximize the beneficial effects, a multidisciplinary well-trained team is needed, with emphasis on integrating parents and the school environment.

The purpose of this study was to describe mother -infant interacting behavior patterns related to newborn infant feeding and to explore the mother's cultural belief about their infant. The data collection was conducted by observation and interview. Twenty-five mothers and their newborn infants who were normally delivered and were also planned to breast feed were comprised as the subjects of this study. All subjects were interviewed and observed individuaily at 1 to 5 days after the delivery at the hospital, mid -wife's clinic, Maternal Child Health Center and their home throughout the country from remote area to big city, The observation data were recorded with symbolic letter on a recording sheet newly developed as a result of preliminary study. The interview data were taperecorded and then recorded in narrative form. Mother - infant interaction behaviors in early feeding period were analyzed based on 19 analytic sub-categories and their composing elements. Unit of analysis were mother, infant and mother -infant dyad. 8 analytic categories draw from the data. Each were preparation, instrument, interaction inducing, evaluation referred to mother's behavior, preparation, instrument, interaction inducing referred to infant's behavior and synchronic behaviors referred to mother - infant dyad. Frequencies of behavior items based on the categories were converted to percent. The result showed that in mother's preparation behavior, the breast condition of Korean mother can be an affecting factor for mother - infant interaction during feeding, and vocalization behavior was observed most frequently in interaction inducing behavior while the least frequent behavior observed was contacting. Subcultural characteristics of mother - infant interaction behaviors were analyzed for their relationships between groups of mothers who have lived in remote area vs urban area, and who were multipara vs primipara. Using a chi -square test, there were statistically significant relationships in the activity of psychological readiness in preparation behavior and the movement of extremities for the position of instrumental behavior in both groups. However, interaction inducing behaviors were not related with statistical significance in any set of groups. Accomplishment of marriage, bonding and emotional mediation of family members were the categories related to mother's cultural belief about the infant in aspect of functional values. Infant at birth is considered little more than a biological organism without social capabilities. Although the newborn infant is still be attached to his mother, he makes his mother extend her territoriality. The mother's interacting behavior toward her infant based on those beliefs appeared task oriented, separative behavioral series. On the other hand, it was seen that infant reacted independently to his mother's behavior by the in-nate perceptual abilities. Those independent behavioral series of mother and infant on the feeding situation were synchronized at any moment. Nurses are In a unique position to teach mothers about their infant's capabilities and help reducing some of uncertainty about infant's behaviors. Study results indicated that the informations infant's social capabilities and breast feeding should be given to the mothers. The results of this study have several implications for nursing. First, the study results will be used as fundamental resources for the development of the assessment tool about the early mother - infant interaction. Second, the results could be a relevant information in the fied. I of maternal child nursing education as real and useful data. Third, the behavioral patterns of early mother - infant interaction which were classified based on the qualitative analysis could be used for nursing theory development as very fundamental data.

Objectives: This study aims to assess the concentrations of ammonia and hydrogen sulfide according to task unit area at swine farms. Methods: A total of six swine farms were selected for this study. Ammonia and hydrogen sulfide were monitored using a real-time multi-gas monitor which could sample the gases simultaneously. The sampling was done in the pig building, manure storage facility and composting facility of each farm. Results: The concentration of ammonia in the pig buildings(GM 22.6 ppm, GSD 2.3) was significantly higher(p<0.0001) than in the manure storage facilities(GM 10.4 ppm, GSD 2.7) and composting facilities(GM 8.6 ppm, GSD 2.8). The concentration of hydrogen sulfide in the manure storage facilities(GM 9.8 ppm, GSD 3.2) was higher(p<0.0001) than in the pig buildings(GM 2.3 ppm, GSD 2.3) and composting facilities(GM 1.9 ppm, GSD 2.5). In particular, the levels of hydrogen sulfide in the confined manure storage facilities were higher than those in open-type facilities and the peak concentration(98 ppm) in the confined facilities was approximate to 100 ppm, at the value of Immediately Dangerous to Life or Health(IDLH). Conclusions: Suffocation accidents caused by hazardous gases at a swine farm have occurred annually. Real-time monitoring of the hazards should be done in order to protect farm workers and livestock from the sudden accidents.

This study was undertaken to delineate the relationship between numerical score and the amount of nursing hours required in the nursing process. Score was a numerical description of the patients functional nursing needs. Therefore this study focused on standard nursing hours required by patient's self-care status. This study observed the 62 patients and 15 R.N. in H. university hospital from Aug. 7, 1982 to Aug. 13, 1982. 1. For the first time, each head nurse assessed self-care status by Schoening's self-care score-Minimal care patient (self-care score: 23, 24) was placed in Group Ⅰ, intermediate care patient (self-care score: 11∼22) was Group Ⅱ, and special care score: 0∼10) was Group Ⅲ. 2. We observed and recorded the nursing care received from nurses according to patient's group. (8AM∼4PM) 3. And, We observed and recorded the activities of nurses in order to determine standard nursing hours required. (8AM∼4PM) 4. If we apply the content of paragraph 3 to paragraph 2, we will predict the number of patient that nurse can care during day time by self-care status. The following results were obtained: 1) Patient's mean self-care score were Group I : 23.9 score Group Ⅱ：17.8 score Group Ⅲ : 1.6 score 2) Nursing hours required by patient's physical function(self-care status) status were Group I : 35 min. Group Ⅱ: 47.5 min. Group Ⅲ : 104.6 min. 3) Nurse's nursing time and distribution required in nursing activities during day duty were A.D.L. : 84.3min. (17.56％) Functional nursing activities : 279.9min. (58.31 ％) Education ＆ Emotional support : 11.3min. (2.35%) Task unrelated patients : 54min. (11.25%) Non Productive nursing care : 50. 5min. (10.52％) 4) Mean nursing hours required by each patient and the number of patient that nurse can rare during day duty by self-care status were Group I : 38.6min. 11.1 patients/1 nurse Group Ⅱ : 51.1min: 8.4 patients/1 nurse Group Ⅲ： 108.2min. 4 patients/1 nurse It seems reasonable that this could be done effectively as each-unit has an established standard for hours required, This not only allows time for planning of staff but helps to avoid the very human inclination to predict excessive staffing requirements by placing the majority of patients in high care group.

To suggest a standard concerning with the arrangement of bridge equipment, the authors conducted the video observations with 3CCD (charge coupled device) cameras installed on the ceil of the bridge for monitoring the working activities of two bridge teams (the skipper/mate1 and the skipper/mate2) in a Korean coastal large trawler(gross tonnage: 139) for five days from July 30th. 2010 and analyzed of the data. Work elements coded by the work activities were input on the sheet of work analysis by the time unit of 1 sec according to the time occurred. A single work element among the work activities for every 5 minutes was denoted as the number of occurrence. The frequency of equipment usage was limited only in the usage of the equipment. In the case of the navigation and the towing net two ranks were integrated and analyzed. On the other hand, in the case of the casting net and the hauling net, two processes were integrated to as one and then analyzed separately as two ranks. As the results, 15 elements of work was carried out between two bridge teams for the observation; lookout, radar, GPS plotter, fish finder, net monitor, fishing deck, RPM indicator, rudder angle indicator, compass card, for maneuver; steering, ship speed control, trawl winch operation and external communications, paper works and others. It was found that the work load of the skipper per 5 minutes accordance with the navigation, the casting net, the towing net and the hauling net are 20.5 times, 11.9 times, 38.0 times and 9.5 times respectively, the mates are 65.2 times, 66.5 times, 85.7 times and 59.1 times respectively. The radar was shown the highest frequency of the equipment usage and the next was the fish finder, the GPS plotter and the external communications in the case of the navigation. In the case of the towing net the frequency of usage was high the ranking as the radar, the net monitor, the fish finder, the GPS plotter, the steering system and the external communications. In the case of the integrated process both of the casting and hauling net the trawl winch was shown the highest frequency to the skipper and the next was the GPS plotter and the radar, and the steering system was shown the highest frequency to the mate and the next was the radar, the ship speed control system, the GPS plotter, the net monitor and the fish finder.

The manufacturer of a linear accelerator (LINAC) has reported that the target melting phenomenon could be caused by a non-recommended output setting and the excessive use of monitor unit (MU) with intensity-modulated radiation therapy (IMRT). Due to these reasons, we observed an unexpected beam interruption during the treatment of a patient in our institution. The target status was inspected and a replacement of the target was determined. After the target replacement, the beam profile was adjusted to the machine commissioning beam data, and the absolute doses-to-water for 6 MV and 10 MV photon beams were calibrated according to American Association of Physicists in Medicine (AAPM) Task Group (TG)-51 protocol. To verify the beam data after target replacement, the beam flatness, symmetry, output factor, and percent depth dose (PDD) were measured and compared with the commissioning data. The difference between the referenced and measured data for flatness and symmetry exhibited a coincidence within 0.3% for both 6 MV and 10 MV, and the difference of the PDD at 10 cm depth ($PDD_{10}$) was also within 0.3% for both photon energies. Also, patient-specific quality assurances (QAs) were performed with gamma analysis using a 2-D diode and ion chamber array detector for eight patients. The average gamma passing rates for all patients for the relative dose distribution was $99.1%{\pm}1.0%$, and those for absolute dose distribution was $97.2%{\pm}2.7%$, which means the gamma analysis results were all clinically acceptable. In this study, we recommend that the beam characteristics, such as beam profile, depth dose, and output factors, should be examined. Further, patient-specific QAs should be performed to verify the changes in the overall beam delivery system when a target replacement is inevitable; although it is more important to check the beam output in a daily routine.

음식물쓰레기의 효과적인 처리를 위해 발효소멸기를 제작하고 유기물 분해능이 우수한 균주들을 접종하여 음식물쓰레기의 감량과 악취제거능을 조사하였다. 먼저 Bacillus subtilis (cellulase 생성), Bacillus cereus (amylase 생성), Sphingobacterium faecium (protease 생성)를 분리하여 효소의 활성을 조사한 결과 각각 최대 153, 219, 412 unit/ml의 우수한 활성을 나타냈다. 미생물에 의한 음식물쓰레기의 처리효과를 확인하기 위해 먼저 간헐적 통기시의 감량효율을 검토한 결과 15일 후 접종시료가 약 11%, 비접종시료가 3.4%의 분해율을 나타내었다. 간헐전 통기시 pH가 급격히 낮아지면서 처리효율이 낮아지는 문제를 해결하기 위해 지속적으로 통기시키면서 음식물 쓰레기 처리 효율을 측정한 결과 간헐적 통기에서의 처리 효율에 비해 약 10% 정도 분해율이 증가했고, 교반기 내부의 pH가 5$\sim$7 수준에서 유지되었다. 음식물 쓰레기 처리에 가장 적합한 조건을 찾기 위해 pH와 온도를 조절하면서 분해효율을 조사한 결과 pH 7, $30^{\circ}C$에서 15일 후 가장 우수한 35%의 분해효율을 나타냈다. 한편 음식물 쓰레기가 분해되면서 발생하는 악취를 저감시키기 위해 biofilter를 제작, 장착함으로써 제어하고자 하였다. 황 화합물을 산화시키는 홍색비유황세균을 함유한 biofilter를 장착함으로써 5$\sim$6배 정도로 복합악취를 저감시킬 수 있었으며, 악취 원인물질 중 중요한 황 화합물인 methylmercaptan은 213 ${\mu}g/L$에서 158.6 ${\mu}g/L$으로, hydrogen sulfide 또한 2473.8 ${\mu}g/L$에서 1262 ${\mu}g/L$로 크게 감소하였다. 이 연구 결과는 음식물쓰레기의 효율적인 처리 및 악취제거에 기여할 수 있을 것으로 판단되며, 음식물쓰레기 처리에 이용할 수 있는 미생물자원의 확보 측면에서도 큰 의의가 있다고 할 수 있다.
