Welding is one of the most fundamental and necessary work in the industry that demand sophistication of skilled workers. This study is to introduce welding simulator as a training tool, to verify its effectiveness and to measure satisfaction of the trainees. A group of freshman students at a Korea Polytechnics College in their twenties with less experience of welding participated in the study. They were divided into two groups and took a traditional training course (comparison group) and a training course with welding simulator applied reality/haptic technology (experimental group) for same hours respectively. To evaluate training effect, a national certificate test and a survey based on Phillips' ROI (Return on Investment) methodology were conducted by the students and the college respectively. And satisfaction survey among the students based on Kirkpatrick's Four-Level Evaluation Model was also carried out. The results showed that all students in the experimental group passed the national certificate test and the ROI of the experimental group for five years were 110% higher than the comparison group. Furthermore, 25% more students in the experimental group replied "very satisfied" about the overall training course and 75% more students in the same group found that the simulation was very similar to the real welding.

The current employment status among young home economists and perspectives in occupations for prospective Home Economics graduates were explored in this study which utilized information from 17 to 21 colleges in Korea and colleges in the United States during the five years of 1977∼1981. The Home Economics content areas covered in this study were Clothing and Textiles, Foods and Nutrition, Housing and Interior Design, and Child Development and Family Life. The highest percentage of Korean graduates in Clothing and Textiles was employed either as teachers at the junior high school level or as designers in the clothing and textile industries. Quite a number of the graduates were engaged in further studies at the graduate level. Korean graduates with a master's degree were teaching at the college level and some had furthered their studies at the doctorate level either here or abroad. Koreans with a bachelor's degree in Foods and Nutrition held jobs as teachers in junior high school, dieticians at mass feeding institutions and hospitals, food scientists in food industries, and researchers in institutions. Those with a master's degree were teaching at the college level. Americans with a bachelor's degree worked as dieticians, supervisors in restaurants and institutions, extension workers, researchers at various facilities, teachers and clerks. Americans with a master's or doctorate degree were engaged in teaching at colleges or supervising at research or working as extension specialists. In general, Korean graduates were found to hold positions in less varied areas than their American counter-parts. Among forty-nine graduates those working in their professional field reported less sex discrimination that those working in other fields. The major area of employment in Housing and Interior Design or Home Management graduates in Korea was teaching while in the United States it was extension work, business, governmental work and teaching. It was suggested that in the future, career development in Korea be further explored to include extension service, research, social welfare, financial planning, business, free-lancing, funeral home, home-call, and correctional education. Interviews with executives from 6 business enterprises indicated that most of them were aware of the potential contribution home economists could make for their companies but they expressed a negative attitude towards women in general due to their short stay on the job. Jobs held by Child Development and Family Life majors with a bachelor's degree in Korea were mostly teaching positions in public, junior and senior high school. However, jobs such as nursery school teaching, working in clinical setting, business, and teaching at public, junior and senior high school predominated in the United states. Most Korean graduates with a master's degree were teaching in professional colleges while in the United Stated the job variation among the graduates was rather evenly distributed among teaching at college level, public and high school, nursery school and administration areas. Reports from 7 child development majors on the job indicated that they were paid less that secretarial workers. Only half of them were working in their major area and these expressed satisfaction with their work. Two thirds of the respondents indicated no sex discrimination. It was suggested that in the future Child Development and Family Life majors pursue employment in counseling, guidance, recreation, mass media, administration and outreach work as well as education, research and parent education in services for children, teen-agers, adults and families.

As a result of measuring illumination and making up a question at home visit directly by investigator who trained over twenty days period from October 4 to 24, 1990, in order to render help which illumination problem against house, society against eyes or framing of health instruction potgram by seizing natural lighting actual conditions of house and actual conditions of wearing spectacles and by investigating interrelationship, I can summarize as follows. 1) In property of investigation subject, woman 66.9%, In an age, the twenties was largest of 27.4%, the forties was 20.2%, the fifties was 18.6%, the thirties was 17.4%. In academic career, those of upper secondary school grauates was largest of 28.6%, those who possess university career was 25.9%, those who middle school career was 20.9%, decoding of Korean alphabet was 2%. 2) By a residence area, a big city was 43.3%, farming and fishing villages were 20.3%, the rest was a small town and the administrative office of town, township. In positon of house, the middle area was 43.6%, resident of suburb area was 38.0%. In form of house, a Korean-style house was 40.8%, a western-style house was 34.8%, an apartment house was 11.0%. In the a standard of living, the middle classes 77.2%, the lower classes were 15.3%. In residential house unit of area, from 21 to 30 unit of area was largest of 31.5%, from 10 to 20 unit of area was 19.9%, from 31 to 40 was 18.7%. 3) The wearing spectacles rate of study user was 44.1%. By the area, those who wearing spectacles was more than a half of 50.8% in the resident of big city area. As passing from the farm area to the city, that is being resident of big city was high wearing spectacles rate. In position of house, as being residence in central street showed high wearing spectacles rate. (central street was 51.5%, the middle area was 44.5% and the suburb area was 40.1%.) It seemed similarity difference a variable by position of house from wearing spectacles in standard of 1%. By form of house, wearing spectacles rate those who resident in apartment house was 49.5%, that rate those who resident in a western-style house was high of 49.0%, that rate those who resident in a Korean-style house was the lowest 39.0%. By social position of resident in room, in students case who study showed very high, as university students were very high of 62.3% idn wearing spectacles rate, middle and high school students 'were 50.0%, members of society were 47.6%, workers 20.3%. It seemed similarity difference from academic career in standard of 1%. By an age, the thirties was high of 54.1% in wearing spectacles rate, the twenties was 43.2%, the teenage was the lowest of 11.8%. 4) In illumination of study, over 200Lux was high of 40.1%. but below 99Lux which inappropriate illumination to see the books was 32.4%. Average by area, below 99Lux was 22.7% and over 400Lux was 50.0% in case of wooden floor. As examine by area, below 99Lux was high of 27.0% a case of wooden floor in the big city area, it was not good in illumination passing from the farm area(15.0%) to the city(19.0%). Average illlumination by area of the main living room below 99Lux was high of 37.5%, less than 200Lux was 58.5% of whole. In general, illumination of the main livingroom was inappropriate. By area, the big city was 32.5% below 99Lux, the middle and small city area were 33.8%, town and township area were 45.0%, farming and fishing area were 42.8%. By area, in the big city, illumination of study was 52.5% over 200Lux and 28.9% below 99Lux. In case of the middle and small city, study user of below 99Lux was 38.8% and over 200Lux was 46.9%. In case of the seat of town township, below 99Lux was 34.1% and over 200Lux was 39.7%. In case of farming and fishing area, illumination of study was 33.4% below 99Lux and 48.4% over 200Lux. It tends to high rate of inappropriate illumination. 5) By position of house, in case of wooden floor, less than 100Lux was 24.5% in central street. It was bad illumination than others position of house. In case of the main livingroom, less than 100Lux was 40.4% in the suburb area. It was bad iliumnation than others position of house. In case of study, less than 100Lux was 35.4% in the middle area, it was worse in illumination. In case of the main living room, is seemed similarity difference in standard of 1%. 6) By form of house, in case of wooden floor, illumination of less than 100Lux was 23.8% in a western-style house, it was bad illumination than others form of house. In case of the main livingroom, illumination of less than 100Lux was 47.4% in a Korean-style house, it was remarkably bad illumination than others form of house. In case of study, a Korean-style house was 38.8%, it was very bad illumination than others form of house. In case of the main livingroom and study, it seemed similatrity difference each as P < 0.01 and P < 0.05 in standard of 1%. 7) The wearing spectacles rate of those who use room of illumination over 400Lux was 40.7%, and that of those who use room of illumination less than 100Lux was 28.1%. It seemed similarity differecce in standard of 1%. 8) In period of wearing spectacles, 21.3% of total investigator-highest-was from before five years, 8.6% was from before three years. Among those who use of illumintion less than 99Lux, 34.0% began to wear spectacles from before two years 31.7% was from before five years, 30.3% was from before four years. It seemed similarity difference from period of wearing spectacles by illumination in standard of 1 %. 9) Among cause which sight grow worse, the first was that it was each 33.2% and 27.4% in response rate because watch TV nearly to wearing spectacles person and non-wearing person. The second was that a lot of seeing books was 25.3% in wearing spectacles person and response rate for dark illumination was 7.4% in nonwearing spectacles person. It seemed similarity difference in standard of 1%. (P < 0.01). 10) In experience which take medicine good for eyes, it was 50.1% in wearing spectacles person and 8.5% in non-wearing spectacles person. It seemed similarity difference in standard of 1%(P < 0.01). As we have seen above, inappropriate illumination can be a cause of wearing spectacles. Nevertheless, actually, is realities to indifferent against illumination of house. So it must learn knowledge about health obstacle of illumination through society instruction and school eduction against students as well as general residents. In case that natural lighting is inappropriate structural of house, we must be able to maintain appropriate illumination through artificial illumination. And so eyes which is core of human life have to be protected, related the authorities, related group, and all health medical personnel will organically cooperate with and make efforts.

This study was to research the characteristics of the body shape of Korean woman farmers by the major crops. Four hundred ninety-five Korean woman farmers from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon volunteered for this study. Their major crops were the rice, the pepper, the water melon, the strawberry, the wild rocambole, the sweet persimmon, the grapes, the mushroom, and the chrysanthemums. Twelve body angles were measured from archived the somatotype photographs of the front, the side, and the back. Questionnaires of SF-36 and the farmer's symptom, and the farm-work related movements were surveyed. The results were as follows; 1. Farmers had lower health levels in physical role limit, pain, vitality, and physical function than other occupational workers. 2. Most farmers acted the high-risk ergonomics motions when they worked in the farm. 3. There were significantly different on the both shoulder angles, the hip tangential line slope, the hip breadth angel, in frontal ankle-knee angle, the bending back angle, the dropping breast slope, the abdominis media angle, under the abdominis media angle, the glutea angle, under the glutea angle, and the sideward knee angle(p<.05). 4. Farmers cultivating the low plants such as the water melon, the strawberry, and the wild rocambole showed more banded vertebralis and side knee angles. Farmers cultivating the red pepper showed the dropping the left shoulder and O shape legs. Farmers cultivating the fruit trees such as the sweet persimmon and the grapes showed the less banded side knee angles than other farmer groups. 5. On comparing the same age, farmers showed the older's body shape in earlier and much more than the old living in the city.

Although the perfomance indicators of the nuclear power plants in Korea show optimal, it requires detailed analysis and discussion centered on the radiation dose. As analysis methods, analysis on the radiation dose of nuclear power plants over the past five years was assessed by comparing the relevant radiation dose of radiation workers and per capita average annual radiation dose of the world's major nuclear power stations was also analyzed. The radiation workers over the annual radiation dose limit of 50 mSv were not. The contrast ratio of the radiation exposure according to the reactor type was the normal operation of PHWR was 6.2% higher than those of the PWR. This shows the radiation work of PHWR during normal driving operation is much more than those of PWR. According to the Performance Indicators of the World Association of Nuclear Operator, the annual radiation dose per unit in 2013 showed 527 man-mSv of Korea is the best country among the major nuclear power generating states, the world average was 725 man-mSv. The annual per capita radiation dose is about 80% less than 1 mSv of the public dose limit and also the average per capita dose showed a very low level as 0.82 mSv. Workers in related organizations showed 1.07 mSv, the non-destructive inspection agency workers showed 3.87 mSv. The remarkable results were due to radiation reduced program such as development of radiation shielding and radiation protection. In conclusion, the radiation exposured dose of nuclear power plants workers in Korea showed a trend which is ideally reduced. But more are expected to be difficul and the psychological insecurity against the operation of the nuclear power plants is existed to the residents near the nuclear power plants. So the radiation dose reduction policy and radiation dose follow up study of nuclear power plants will be continously excuted.

The main purposes of the nutrition and clinical surveys were to provide baseline information on the nutritional status of pre-school children in rural health demonstration project areas of the Korea Health Development Institute (KHDI) for nutrition guidance services for the MCH target group. The survey covered a total of 222 pre-school children and 135 mothers in Okgu Gun, Cholla Pukto Province from August 10 to August 17, 1979. The survey results are summarized as follows: 1) Family Environment Seventy percent of the households had more than three children, and the mean family sire was 6. Sixty-nine percent of the mothers and 47% of the fathers of the surveyed households were educated at or below the primary school level. The majority, 70% of the mothers, were aged between 20 years and 35 years. 2) Anthropometric Measurements and Hemoglobin Value 4.5% of the children were lower than 80% weight for age of the Korean standard, and 5.4% were lower than 85% arm circumference for age of the Jelliffe's standard resectively, and those were suffering from protein-energy malnutrition. Angular stomatitis were observed on 66.2% of the subjects. Mean hemoglobin value was 11.1g/100m1, and 44.2% of the subjects were categorized as anaemia. 3) Food and Nutrient Intake of animal foods was very low, ranging from 2.9 to 17%. Consumption of eggs was less than 2% of total food intake, and intake of legumes was also very scanty, between 0.8 to 3.7%. These data present evidence of very poor protein intake, quality as well as quantity. Energy intake of children was 60.0 to 64.4% of the recommended allowance, and mean protein intake only met 47.4% of the recommendation. Low intake of vitamins except thiamin were also found. 4) Mother's Nutrition Knowledge Eighty-five percent of the mothers were entirely ignorant regarding the 'five basic food group' which is most important fact on food and nutrition guidance. Mean knowledge score from 14 basic questions about food and nutrition was as low as 5.1. There was a significant positive correlation between mother's educational level and nutrition knowledge score. 5) Family Planning Variable There were significant correlation among maternal, family planning variables, and some of the nutritional and physical measurements. The study revealed that the mother's educational level and nutrition knowledge score are more crucial factors than the family planning variables on effecting food intakes on children. Recommendation : According to the results of the surveys, there were high incident rates of nutritional anaemia and angular stomatitis among pre-school children, and most of rural women had very limited knowledge about food and nutrition. As a main part of the health education activities, the community health workers should provide nutrition education to the village mothers to improve the nutrional status of young children in rural areas. Nutrional promotion at the primary health care level should be mainly based on appropriate nutrition education.

As the probability of exposure to radiation increases due to an increase in the use of radioisotopes and radiation generators, the importance of a radiation safety management field is being highlighted. We intend to help radiation workers with exposure management by identifying the degree of radiation exposure and contamination to determine an efficient method of radiation safety management. The personal exposure doses of the radiation workers at the Korea Institute of Radiological & Medical Sciences measured every quarter during a five-year period from Jan. 1, 2011 till Dec. 31, 2015 were analyzed using a TLD (thermoluminescence dosimeter). The spatial dose rates of radiation-controlled areas were measured using a portable radioscope, and the level of surface contamination was measured at weekly intervals using a piece of smear paper and a low background alpha/beta counter. Though the averages of the depth doses and the surface doses in 2012 increased from those in 2011 by about 14%, the averages were shown to have decreased every year after that. The exposure dose of 27 mSv in 2012 increased from that in 2011 in radiopharmaceutical laboratories and, in the case of the spatial dose rate, the rate of decrease in 2012 was shown to be similar to the annual trend of the whole institute. In the case of the surface contamination level, as the remaining radiation-controlled area with the exception of the I-131 treatment ward showed a low value less than $1.0kBq/m^2$, the annual trend of the I-131 treatment ward was shown to be similar to that of the entire institute. In conclusion, continuous attention should be paid to dose monitoring of the radiation-controlled areas where unsealed sources are handled and the workers therein.

This study has been performed to come up with any rational way for responding to the functions of fire-fighting spaces newly required by the changing social paradigms and to seek for the approach to designing fire-fighting spaces by taking into account the psychological and behavioral factors of fire-fighters who are exposed stress of operations. In particular, it is to satisfy any physical and functional requirements as special working-spaces and to reflect the psychological and behavioral approach to the workers who are forced to be at standby for a long time, which is the characteristic of their operation, to designing. Accordingly, for fundamental appreciation of whether or not such space programs as space organization needed for operational function are being practiced actively, the fire-fighting headquarters of Incheon City has been selected for the research. First, in the process of assessing the trend of organizing the space at safety centers for the recent 20 years, those built more than 20 years ago were left out from the space selection for the research. Second, those with less than 20 operators also were excluded. Third, among those completed in the same year, only one was selected, which was to avoid overlapping, with the consideration its regional representative nature for applying the safety centers in the jurisdiction of the headquarters equally. The study was performed through the visits to and the actual inspections by surveys at the selected 119 Safety Centers as well as the reviews of literature based on case studies. And for the assessment of significance, surveys and analysis of reliability and factors were carried out. The actual users of Safety Centers were picked as objects for the assessment of significance of space factors at 119 Safety Centers, which revealed that there are five types of dimensions for factor-analyzing standard with which users estimate any significance, which are "Area of Mobilization Preparation and Return" "Area of Standby" "Area of Working Activities" "Area of Employ Welfare" and "Area of Support".

The purpose of this study was to examine how medical personnels in the field of dentistry perceived the introduction of the yearly income system in an effort to determine some of the right directions for that and find out in which way that could be vitalized. For that purpose, literature concerned and relevant materials were reviewed, and a survey was conducted on 95 medical personnels, who were working at dental hospitals and clinics throughout the nation, for approximately five months from April through August 2002. After the collected data were analyzed, the following findings were acquired; (1) Regarding their awareness of the yearly income system by the type of institute, the workers from the dental hospitals found the yearly income system, more than the others from the dental clinics did, to enlarge their sense of involvement in management (p<.001), further work productivity(p<.01), awake their target-oriented sense of mission(p<.01) and make them feel uneasy about their future(p<.05). (2) As to differences between the dentists and dental hygienists, the former group had a higher opinion about that system(p<.01) and its effect on impartial performance appraisal(p<.01), encouraging medical personnels to deploy their abilities(p<.01), furthering work productivity(p<.001), intensifying a target-oriented sense of mission(p<.001). (3) Concerning their perception by career, those who had longer experience to work in that field considered it to strengthen work severity(p<.05) more than the others who had shorter experience did, and the former group thought that system was more likely to concentrate on a short-term achievement (p<.05). The workers who had been working for three to five years were more conscious of change in office hours (p<.01), and those who had been working for two or less years viewed that system most favorably(p<.05). (4) In order for that system to be successful, impartial performance appraisal was most widely called for(31.6%), followed by trust between labor and management(26.3%), worker's positive attitude toward that system(16.8%), CEO's firm belief in that(12.3%), and setting up a feasible target. The workers from the dental hospitals put more stress on medical personnel's favorable attitude toward that system(p<.05) than the others from the dental clinics did. And the dentists placed more stock in setting up a feasible target, which was a criteria of determining the amount of annual income, than the dental hygienists did.

The research was conducted by center for children's foodservice management in Hanam-si. In order to improve job satisfaction, a survey was carried out by working conditions and job satisfaction in children foodservice employees working at child daycare centers registered from January to April. Ninety-five surveys out of 120 were collected, and 76 surveys were analyzed. Job satisfaction consisted of four elements, working environment, welfare, human relationships, and job-itself, analyzed by general characteristics. Pearson's correlation was carried out between job satisfaction and intention to change job by Likert 5 scales using SPSS statistic program. The percentages of child daycare centers owned by civilians was 52.6%, high school education level was 65.8%, permanent workers was 68.4%, and less than 1 year of foodservice was 34.2%. Average scores of job satisfaction were as follows: working environment scored 20.6 out of 25 points, welfare scored 10.3 out of 15 points, human relationships scored 17.5 out of 20 points, and job-itself scored 13.2 out of 15 points. The lowest job satisfaction average was 'I get paid fairly regarding the working hours and the amount of work' with a score of 3.6 points. Job satisfaction based on facility type, age, education level, and working period did not show significant differences, whereas hired status, numbers of foodservice children, and intention to change jobs showed significant differences. Hired status showed significant differences with welfare satisfaction (P<0.05). Numbers of children showed a significant difference with welfare and human relationship satisfaction (P<0.01, P<0.05). Intention to change job showed a significant difference with four elements of job satisfaction (P<0.05, P<0.01, P<0.01). In conclusion, to improve job satisfaction of children foodservice employees, working conditions and welfare satisfaction should be increased.
