The community health practitioners (CHP) play an important role in primary health care services to the underserved population in rural area. Time and motion study of 26 CHPs in Kyungpook Province was conducted through work diary method for 6 consecutive days from the time they arrived until they left the primary health post(PHP) during the past 3 weeks from November 16 to December 5, 1987. The allocation of activity time by working category, service category, location of activity and CHP's function was analyzed according to the characteristics of CHPs i. e., age, marital status and experience as CHP. The major findings are as follows : The mean activity time per CHP in a week was 2,918 minutes. The length of their working hours was longer for older, married and more experienced CHPs than others. About 80% of the CHP's activities took place within the PHP and only about 20% occured outside of the PHP. Working hours for the outdoor activities were longer for younger, single and less experienced CHPs than others. The allocation of activity time by working category showed 46.3% in the technical work and 18.7% in the administrative work. Working hours for the technical activities were longer for younger, single and less experienced CHPs than others. The percentage of activity time revealed greatest as much as 63.1% for direct patient care in technical work and 61.6% for record keeping in administrative work. Of the total working hours in a week, direct patient care and public health activities accounted for 29.2% and 16.2%, respectively. Of the indoor activities, working hours for direct patient care were longer than those for public health activities. However, of the outdoor activities, working hours for public health activities were longer than those for direct patient care. The allocation of activity time by CHP's function showed 49.7% in management of common disease, 31.8% in management of PHP and technical supervision of village health workers, 9.5% in MCH and family planning, 6.6% in community health management and 2.4% in community approach. Based on these findings, it was found that CHPs were mainly working in the PHP with a majority of their time being spent for direct patient care rather than preventive and promotive health cares. To enhance the preventive and promotive health services of the CHPs and to involve the activities for community development, refresher course for CHPs should be reinforced and supervision mechanism of the CHPs should be established and operated in Gun- and province-level.

Dental caries has a multifactorial aetiology in which there is an interplay of three principal factors: the host(saliva and teeth), the microflora(dental plaque) and the substrate(diet), and a fourth factor time. There is no single test that takes into consideration all these factors and can accurately predict an individual's susceptibility to dental caries. The risk of dental caries can be evaluated by analysing and integrating several causative factors. The objective of the study was to clarify the relationship between caries activity and the status of caries of primary teeth and the relationship between the quantity of S. mutans in the dental plaque and the status of dental caries. Forty nine children ages 5 were examined with caries indices, Dentocult-SM and quantity of S. mutans. The results were as follows: All the survey results were similar with national means of 5-6 years Korean preschool children. The deft index of subjects was 5.46 and defs index was 9.81. There was 8.6% of negative, 10.9% of mild, 28.1% of moderate and 52.3% of active results at screening strip test. 8.6% was negative, 17.2% was mild, 33.6% was moderate and 40.6% was active in site strip test. The Spearman correlation coefficient was 0.775, and overall kappa index was 0.496 between screening strip test and site strip test. There also was a high correlation between caries incidence, Dentocult-SM test, and quantity of S. mutans. Dentocult-SM test as a caries activity test is a reliable method for measuring the status of dental caries in primary teeth.

We arrive at the conclusion as follows as for the connection between dietary life, hours of exercise and growth of body, based on the survey of their height, this circumference of the breast and their body weight, and the questionnaires to the pupils of 36,547 in totals (contained the primary and middle school boys and girls) in four districts(named A, B, C and D district) of Jeonlla Bug Do from April, 1970 to March, 1973. (1) The growth in height. The boys from 6 to 7 years old are nearly same in all districts, but as age increases, those of A district grow more rapidly than those of B, C and D districts, while those of B, C and D districts grow almost samely. The girls already from 6 years old on are different between A district and B, C, D district. The average of height in Jeonlla Bug Do is not different from that of Gyungi Do and whole nation in the pupils from 6 to 11 years old, and that of Japan from 6 to 7 of age, while it falls behind them as age increases. (2) The growth in the circumference of the breast. The boys from 6 to 9 years old show nearly the same tendency in all districts, after that age the boys in A district tend to grow rapidly, those in B district most fall behind, and those in C, D districts show the same tendency. Contrasted with height the growth in the circumference of the breast does not show the difference in each district so far as 14 of age, but after 15 years old it shows a little difference by falling behind of pupils in A district, while those B, C, D districts show almost the same tendency. The average of the circumference of the breast in Jeonlla Bug Do of the pupils from 10 to 11 of age is almost same to that of Gyungi Do, whole nation and Japan, but shows difference after that age. (3) The growth of body weight. The body weight of boys over-all the investigated whole age shows the superiority in A district and a little lowness in D district which is almost same to that of B, C districts. In that of girls, A district is superior in from 6 to 9 of age, and all districts are nearly same after that age. The average in Jeonlla Bug Do is one and the same to those of Gyungi Do, whole nation and Japan as in the height, but shows the great difference as years grow. (4) The dietary life of the pupils in Jeonlla Bug Do depends chiefly upon a carbohydrate and is very low in the intake of fat and protein. Connected with a view point of districts, the intake of protein is a little more in A district than in the other districts, and is nearly same in the other districts. They tend more to eat mixed food, but about 40% of them do not yet eat it. The contents and taking of lunch is bad in the highest degree, to which their parents are entirely indifferent. As far as the hours of exercise are concerned with, about 40% of all pupils must go to the school from very far, which gives them the heavy physical suffering, and especially it is remarked that the middle school boys and girls should attend school from farther than the primary school boys and girls.

During the period between July 3 and 27 of 2009, water samples were collected from the Russian coast at a depth of 30m from 26 stations (including Ulleung and Japan basins) onboard the Russian survey vessel R/V Lavrentyev following 4 lines (D, R, E, and A). The samples were analyzed for nutrients and chlorophyll a contents. All parameters exhibited higher values in warm waters than in cold waters ($NH_4:1.8-fold$, $PO_4:1.8-fold$, $SiO_2:1.2-fold$, and chlorophyll-${\alpha}$:1.9-fold), except nitrates, which was 1.4-fold higher in cold waters than in warm waters. The horizontal distribution of ammonia, phosphate, and chlorophyll-${\alpha}$ was very similar to each other and showed the highest values in the waters near Russia, where a upwelling influence of cold current and bottom water prevails, while relatively low distribution was observed at the Ulleung Basin. On the other hand, nitrates showed the highest concentration at the Ulleung Basin, which is under the direct influence of the Tsushima warm water, and showed a gradual decrease northward. The N/P ratio showed the highest value in the Tsushima middle water, rather than in the North Korean Cold Water, the Tsushima Warm Water was the primary source of nitrate flow into the East Sea. However, the average concentration of phosphate in the warm waters was < $0.2{\mu}M$, thereby limiting phytoplankton growth, while a high concentration of phosphate in cold waters showed a direct correlation with chlorophyll-${\alpha}$. The results of principal component analysis for the identification of primary factors that influence the marine environment showed that principal component I was water temperature and principal component II was influenced chlorophyll-${\alpha}$ and nutrients. Therefore, Study area has greatest influenced by water temperature, and clearly distinct cold and warm water regions were observed in the East Sea.

The purpose of this Study was to investigate the prevalence rate of idiopathic scoliosis to the students from the elementary to the university in S city of Chung-Nam using 100 mm Mirror Camera radiation indirect examination units, with on age range of between eight and thirteen (1.526 subjects), fourteen and sixteen (462 subjects), seventeen and eighteen (291 subjects), nineteen and twenty four(508 subjects) and total of 2,787 participants with the 590 male subjects and 2,197 female subjects. The results of this study can be summarized and compared the primary examination with the secondary test of greater than $10^{\circ}$of Cobb's Angle were obtained as follows; 1. Indirect Examination were conducted to find idiopathic scoliosis amomg total 2.787 subjects, 257 subjects (9.2%) who showed positive sign greater than $10^{\circ}$in the Cobb's Angle ; below age of thirteen (132 subjects), between fourteen and sixteen (52 subjects), seventeen and eighteen (35 subjects), nineteen and twenty four (38 subjects). The $x^2-test$ analysis of Indirect Examination showed no statistical significant difference association between the age range and $10^{\circ}$Cobb's Angle of spinal curve(P>0.059). 2. The numbers of idiopathic scoliosis of greater than $10^{\circ}$Cobb's Angle of spinal curve in the primary examination were observed in 147 subjects (57.2%) at the Thoracolumbar region, 81subjects (31.5%) at the Thoracic region, 20 subjects (7.8%) at the Cervicothoracic region, 7 subjects (2.7%) at the Lumbar region, 2 subjects (0.8%) at the Cervical region. So, the large numbers were Thoracolumbar region, 183 participants (71.2%) showed the right side curve of scoliosis and 74 participant (28.8%) showed the left side curve of scoliosis. 3. The main region of the pain in one's own self more than $10^{\circ}$ Cobb's angle of spinal curve were no pain 219 subjects (85.2%), 18 subjects (7.0%) at the Lumbar region, 9 subjects (3.5%) at the Cervical region, 7 subjects (2.7%) at the Thoracic region, 2 subjects (0.7%) at the shoulder girdle region, 1 subjects (0.39%) at the pelvis and whole body region. There was statistical significant difference association between the Cobb's Angle of spinal curve and the main pain region of one's (P<0.006). This study may be significant to an early stage investigate of the prevalence rate of idiopathic scoliosis in the juveniles using 100 mm Mirror Camera radiation indirect examination units.

Purpose : We analyzed the demogaphic data md clinical course of Korean children with chronic renal failure (CRF) observed between 1990 and 1999. Patients and Methods : Questionnaires were mailed to all children's hospitals ail through the country. We asked for primary renal disease age and serum creatinine levels at first presentation with CRF and end-stage renal disease (ESRD), and modes of renal replacement therapy (RRT). Results : 401 children (254 boys, 147 girls) with CRF, defined as a permanent increase of serum creatinine above 1.2 mg/dl for at least 3 months or until death, were identified. This represents an incidence of 3.68 per million child population per year. Of these patients, 22$\%$ on younger than 5 years, 28$\%$ 5 to 10 years and 50$\%$ 10 to 15 year. Eight five $\%$ of the patients could be classified with a primary renal disease. The most frequent cause is glomerulonephritis (36$\%$), followed by chronic pyelonephritis (21$\%$), renal hrpo/dylplasia (9$\%$), and hereditary nephropathies (7$\%$). Reflux nephropathy (16$\%$) was the most common single cause of CRF. ESRD was reached in 70$\%$ of all patient. 99.3$\%$ of these started RRT. Hemodialysis (HD, 42$\%$), peritoneal dialysis (PD, 35$\%$) and transplantation (TP, 23$\%$) were performed as the initial mode of RRT. A total of 161 TPs were performed (159 first grafts, 2 second grafts). A total of 32 patients died. The main causes of death were dialysis related complication in HD patients and infections in PD patients. Survival rate on any form of RRT was 88.7$\%$ during the mean follow-up period of 37 months. Conclusion Major efforts should be directed toward earlier diagnosis and treatment of reflux nephropathy to prevent occurrence of Of. Dialysis and TP have now become well accepted forms of treatment in Korean children with ESRD.

This study intends to investigate the main and mediating effects which caregiving appraisal and positive reappraisal exert on quality of life (QOL) of primary family caregivers of cancer patient considering the relationship with social support. The processes of this study areas follows. First, the variables which research model were chosen on the basis of stress-appraisal-coping theory through reviews of the previous studies. Second, a survey was conducted upon 295 primary caregiver of patient with cancer at National Cancer Center. Collected data were analyzed by SPSS 12.0 and SEM (Structural Equation Modeling) method using AMOS 5.0. The summary of the result is as follows. First, the entire model including measurement and structural model shows sufficient fit index of CFI(.951), TLI(.940) and RMSEA(.062). Second, the results of analysis of direct effects among variables are as follows. The 'Social support' has statistically significant direct effect on the 'feeling of burden' and 'growth'. The 'feeling of burden' has statistically significant direct effect on the 'growth' and 'QOL-mental and physical'. The 'growth' has statistically significant direct effect on the 'QOL-mental'. Third, the results of analysis of mediating effects of the 'social support and QOL' and 'feeling of burden and QOL' are as follows. The effects of 'social support' on 'QOL-mental' are significantly mediated by the 'feeling of burden' and 'growth'. The effects of 'social support' on 'QOL-physical' are significantly mediated by the 'feeling of burden'. The effects of 'feeling of burden' on 'QOL-mental' are significantly mediated by 'growth'. Through this research, these implications in social work study and practice are found: (1) this study extended the scope of study in the caregiver's health area from negative sides into positive ones by using growth variables as positive reappraisalof caregiving in research model, which has not been tried on the Korean family caregivers of the cancer patient. (2) The effects of positive reappraisal on QOL-mental can provide a foundational necessity for social workers to help family caregivers find positive meaning in their caregiving experience. This approach of social work practice will improve QOL of family caregivers. (3) This study present a framework including social support, negative appraisal, positive reappraisal, and QOL variables available to social work practice and explaining affective relationships among these variables in various aspects.

The purpose of this study was to develop a narrative analytic scoring rubric through teacher-students negotiations, as an assessment of tasks using methods of experiment and practice for home economic(HE) in the middle school. In this study. an analytic rubric had been developed in the following three stages: In the first stage, all the things for rubric development were defined and prepared, by selecting tasks used for rubric application through a questionnaire survey, providing detailed directions on methods and procedures and needed items, and selecting a class for rubric negotiation and setting the development schedule. In addition, the method suggested by Ainsworth and Christinson(1998) in Student Generated Rubrics was used. In the second stage, performance criteria for tasks in terms of knowledge, skills, and attitude were developed, setting scoring framework and scales depending on assessment areas. Referring to selected scoring framework and assessment criteria, observable and assessable behaviors were used to describe rubric based on A, B, and C scale. Then, a primary rubric was developed through teacher-students negotiations, using rubrics made by group. In the last stage, the developed primary rubric was reviewed by an expert of HE education to test the validity. Moreover, the analysis to test the suitability of the final rubric assessment tool employed 46 copies of questionnaire collected from incumbent home economics teachers selected by way of random sampling mainly focusing on those teachers who were in the Master's degree program or completed the program at one university. As a result, the average of suitability of aa the rubrics were over 4.0 in th 5-point scale.

Background: Cardiac troponin I (cTnI) is a sensitive cardiac marker of myocardial injury. In normal coronary angiogram, positive cTnI values may be detected in various events such as sepsis, stroke, trauma and so on. To investigate characteristics of cTnI positive group in trauma patients, we designed this study between cTnI positive group and cTnI negative group. Method: Trauma patients who visited emergency room within 24 hours after accidents were included. Patients who had renal failure, acute coronary syndrome, sepsis, spontaneous SAH were excluded. Retrospective study of 97 trauma patients was done. We investgated ISS (injury severity score), positive cTnI, EKG abnormality, shock class, ICU admission rate and mortality. Result: In comparing with non chest trauma group, chest trauma group, whose chest AIS (Abbreviated Injury Score) is more than 3 point, had significant values in ISS, positive cTnI, EKG abnormality, shock class and ICU admission rate. Also, in non chest trauma group, we found several patients whose cTnI level was positive. When non chest trauma group was divided into two subgroups, the mortality and shock class of positive cTnI group were higher than that of negative cTnI group. When all trauma patients were divided into two groups, a positive cTnI group had higher values in ISS, shock class, ICU admission rate and mortality than that in a negative cTnI group. Conclusion: We found that cTnI were positive in patients of cardiac contusion but also in various trauma cases. In non chest trauma patients, we assumed that hypotension caused cTnI elevating. The cTnI could play a role in predicting prognosis in trauma patients.

The primary objective of this study is to firstly survey and analyze the working environment and actual condition, secondly know their problems, and then provide the basic data about how to improve their working conditions. The specific study items for getting the goal above is as follows: 1. How does the industrial company connect with highschool vocational education well? 2. How does the mechanical technical highschool graduate apply with industrial field? The result of study is as follows: 1. In case of employment's information and the industrial educationed cooperation, the workers who has the working history in less than 5 years takes short to find the job. National high school graduates and those who get the job through the school and the teacher changed their job at short period compared to other. 2. There was no benefit about the same major's worker at industrial field. The workers admitted that there is the exemption fo military service and the certification's allowance, only for which is related to their job. The longer the workers stay their job, the more they had the chance to get the exemption of military service. National highschool were carried out the curriculum well as planed especially for their major subjects. Whereas, the public and private highschools weren't. The seniors of their job and the coworkers are very helpful for learning the actual knowledge. The workers said that the school's curriculum and club activity weren't effective applying with their working field. 3. The study says that the important things of their job is the knowledge of their major. Those who 80% answered that the worker must improve the knowledge of their major to be a good engineer. Learning from their senior in working field was very helpful. The question above was ranked as the first. 4. The answer says that the new changed job's pay is more than the previous job. That is, the reason of leaving the job is the pay gap. The most dissatisfaction and problems in present job was the environment of working and the working condition. 5. Regarding to asking next year's plan, the answer says that keeping the job was ranked as the first. That answer means that they conservative.
