Objectives: This study was conducted to estimate the cumulative incidence rate (CIR) of unintentional injuries in Korean daily life and to describe the pattern of unintentional injuries. Methods: The study population was the people who used the National Health Insurance because of injuries (ICD code: S00$\sim$T98) during 2006. The stratified sample according to gender, age and the severity of injury (NISS, New Injury Severity Score) was randomly selected. The questions on the questionnaire were developed as a reference for an international classification tool (ICECI, International Classification of External Causes of Injury). The questions included the locations of injury, the mechanisms of injury and the results of injury. Moreover, we used age, gender, region and income variables for analysis. Results: The CIR of unintentional injuries that occurred in daily life for 1 year per 100,000 persons was 17,606, and the CIR of severe injuries was 286. Many injuries were occurred at home (29.6%), public places (19.0%), school (13.7%) and near home (12.0%). The major mechanisms of injuries were slipping (48.8%), contact (14.0%), physical over-exertion (13.8%), and fall (6.6%). Infants and old aged people were vulnerable to injuries, and those who lived rural area and who were in a low income level were vulnerable too. Conclusions: We signified the risk groups and risk settings of unintentional injuries in Korean daily life. These results could contribute to establishing strategies for injury prevention and implementing these strategies.
In this paper, some terms of high school mathematics which read Chinese characters phonetically in Hangul are studied semantically. Nowadays, most terms of high school mathematics are terms of Chinese characters given the reading of them in Hangul alphabet. In such terms of Chinese characters, there are many loan-words from daily life and newly coined terms. Some such terms are examined in respect of meaningfulness and rule-ness. The degree of meaningfulness and rule-ness of loan-words from daily life are relative. Students seems familiar to loan-words usually, but it is difficult to know whether students seems to be familiar to loan-words or not. Degree of familiarity to a certain loan-word must be relative. In loan-words, there are such terms whose mathematical meaning is different from daily life meaning. Such terms are strong in rule-ness. Newly coined terms are strong in rule-ness. Students are not familiar to newly coined terms which are not used in daily life and have only mathematical meaning. In coining new terms using Chinese character, unit characters are related directly or indirectly to concept which unit characters want to express. So, It is possible to guess something unit characters want to express by investigating them. According to Vinner(1991), images can be evoked. But in case of reading Chinese characters phonetically in Hangul, it can not be guaranteed for Hangul mathematical terms to evoke images which the original mathematical terms evoked. To solve such problems semantic investigation of mathematical terms has been suggested. Through this process, transplanting images which the original mathematical terms evoked into Hangul terms are planned.

This study carried out to determine control factors for the improvement of productivity of laying hens suffering heat stress during hot weather. A total of 48,451 ISA Brown layers were housed in a farm located in Gyeongsangnam-do, Republic of Korea. Five thermo-hydrometer loggers were installed inside the house to collect data of dry-bulb temperature and relative humidity. The experiment continued for 81 days when the summer season begins from 19th June to 7th September, 2018. This study analyzed the correlations among layers' production index and daily average, highest, and lowest temperature; daily average, highest, and lowest relative humidity; and daily average, minimum, and maximum THI. The result indicated that feed consumption, hen-day egg production, egg weight, and FCR decreased as the daily average, highest and lowest dry-bulb temperature and THI rise (p<0.01). On the other hand, water intake increased as the daily average, highest and lowest dry-bulb temperature and THI rise (p<0.001). The relative humidity was not considered to have direct correlations to the layers' production index (p>0.05). However, it was noticeable that the mortality did not have significant relations with daily average and highest temperature; THI; or daily average, highest and lowest relative humidity while it was relevant to the daily lowest temperature and THI (p<0.05). In conclusion, to enhance the productivity of laying hens in a hot climate, it is recommended that daily average, highest, and lowest dry-bulb temperature and THI are maintained as low as possible. Especially, the daily lowest temperature is needed to lower to 20℃, which is the lowest critical temperature for layers.
This study analyse the quantitative relationships between the compositive factors of the residential interior space in the view point of physical aspects. The proposed analytical methods are focused on finding the quantitative relationships between the human dimensions of the static and dynamic life style situations and the compositive factors of the architectural interior spaces. As a result, the major analystical methods are ; the analysis of Space-human Body System for finding the quantitative relationships between the human dimensions and the order of architectural structures ; the analysis of Space-Objects-Human Body System for finding the quantitiative relationships between the human dimensions and furniture dimensions of the interior space ; the analysis of Space-Objects - Life Activities of Human Body System for finding the quantitative relation ships between the human dimensions of daily or non daily life activities including static furniture systems.
This study has been performed to analyze impacts of urban vs rural residence on later life. In this study, 329 Koreans aged 60 or more were interviewed for their current sociodemographic status and daily life styles. The results are drawn as follows: 1. There is no regional impact on birth order; rate of those born as the first child was not significantly different over regions. 2. For the household composition, the rate of three generations was significantly higher in rural areas than in urban areas. 3. More than 85% of the subjects lived in owned homes in rural areas, while 77% did in urban areas. 4. More than 89% of the subjects lived in single-structured homes in rural areas, while only 45% did in urban areas. The results indicate that in planning public housing for the aged, more social spaces accommodating grandchildren and ownership units need to be allocated for rural facilities. In addition, it is recommended that daily activity schedules need to be differentiated so that rural residents have meals and houseworks earlier than urban residents.
In this study, the antitumor activities were investigated using $\beta$-lmmunan, a proteoglycan obtained from cultured mycelia of the IY009 strain of Ganoderma lucidum belonging to basidiomycetes. The result showed the significant effect of cytotoxicity test against murine sarcoma 180 and murine lymphocytic leukemia L1210 using immunized macrophage cultures by $\beta$-lmmunan. When intraperitoneally injected at 40 mg/kg/day daily for 10 days, $\beta$-lmmunan inhibited the growth of sarcoma 180 solid tumor in ICR mice by 88.8% (p<0.05). It was also observed that $\beta$-lmmunan increased life span by 85.2% (p<0.01) after treatment of 100 mg/kg/day in BDF1 mice bearing lymphocytic leukemia L1210. And combination therapy with cisplatin (dosage: 4 mg/kg) increased life span by 140.4% (p<0.05) after treatment of 100 mg/kg/day daily in BDF1 mice bearing lymphocytic leukemia L1210.

Purpose : To assess the relationship between post-stroke shoulder pain, motor function, and pain-related quality of life(QOL) Methods : Volunteer sample of 62 chronic stroke survivors with post-stroke shoulder pain and glenohumeral subluxation. The patients answered the question in shoulder pain with the Brief Pain Inventory question 12 (BP1-12), Pain-related Quality of life(BPI-23). Therapists measured the performance of combined upper-limb movement including the hand-behind-neck(HBN), hand-behind-beck(HBB) maneuver, added passive pain-free shoulder external rotation range of motion, and Modified Ashworth Scale(MAS) score of the elbow flexors. Physical performance assessments were used to measure basic activity daily living(Modified Barthel Index-self care, MBI-S/C), motor function of upper limb(Fugl-Meyer Upper/Lower Extremity, FM-U/E). Results : Stepwise regression analyses indicated that post-stroke shoulder pain is associated with the BPI 23, but not with the FM-U/E, MBI-S/C. Thus, the presence of shoulder pain is more important predicting pain-related QOL than its degree in predicting motor function of upper limb and basic activity daily living. Conclusion : Post-stroke shoulder pain was associated with reduced quality of life related to pain. The pain was not associated with the motor function of upper limb and basic activity daily living. The result imply that management of shoulder pain & anatomical position of shoulder joint after stroke should be emphasized. This provides a further incentive to develop effective rehabilitation prevention and treatment strategies for post-stroke shoulder pain.
The first purpose of this study was to give the basic imformations about patent education for fathers. The second purpose was to develop the parenting skills by examining role frequencies of fathers. The third purpose was to reduce the parenting difficulties of father in daily life. The contents of the study was 1. the expectaion and practice of father's role 2. frequencies and difficulties in performing role for daily life 3. socioeconomic factors to affect father's role 4. the correlation between frequencies and difficulties in performing role 5. the correlation among role areas and life satisfaction in father's role The subjects were 520 fathers from 11 cities of Korea. The instruments used for their study were questionnaire composed of socioeconmic factors, the recognition of father's role, child rearing, day-to-day guidance, academic guidance, leisure and hobby, commuication and emotion, economic support etc. The data were analyized using t-test, F-test(LSD), Pearson's correlation by SPSS $PC^+$ program. The main results of the study were as follows: 1. Fathers recognized that desirable fathers are attentive to their children and guide them in the right way. 2. Among father's role frequencies, the communication and emotion was highest and child rearing and academic guidance were the lowest. Among father's role difficulties, economic support was the highest, and dat-to day guidance was the lowest. 3. The socio-economic factors to affect fathering and role difficulties were mother's job, father's home town, age, income, academic career etc. 4. The correlation between father's role frequencies and difficulties was very high. 5. For father's role frequencies and difficulties, each factor was parenting correlated to life satisfaction.
The purpose of this study was to identify the factors that affected to physical functions, activities of daily living (ADLs) and instrumental activities of daily living (IADLs). The subjects for this study, 236 persons, 65 years and over, who were living at rural area in Chun-Cheon city. This survey was carried out from march 3rd to April 25th, 1998. The data was analysed by using SPSS PC+ program. The results were as follows. 1.The variables that were related to the conditions of physical functions were as follows; age, sex, educational level among the general characteristics; raising ways of money, monthly using money for life, states of pocket money, obtaining method of pocket money, state of weight, problems in mind, whether or not chronic illness among socio ㆍeconoㆍphysical conditions; the level of satisfactions in life, subjective condition of health among the subjective thinking ; controlling state in smoking and drinking of alcohol among the lifestyles for promoting health. But the variables for medical utilization were not related to the level of physical function. 2. The variables that were associated with the condition of ADLs were as follows; age among the general characteristics; monthly using money for life, working amount among the socioㆍeconoㆍphysical conditions; subjective conditions of health among the subjective thinking. But The variables for medical utilization, lifestyle for promoting health were irrelevant to the conditions of ADLs. 3. The variables that were related to the conditions of IADLs were as follows; age, educational level among the general characteristics; raising ways of money, monthly using money for life, resident type in the household, procurement method of pocket money, level of weight, problems in mind, wether or not chronic illness among socioㆍeconoㆍphysical condition; regularity of health checking among lifestyles for promoting health; kinds of utilizing medical agent among the variables about utilization patterns of medical agencies; subjective condition of health among the subjective thinking In this study, in the aged there were related factors of physical and life functions, were age, working amount, subjective condition of health.

Objectives: This study is to assess the correlation of the changes in dental health-related quality of life before, during, and after orthodontic treatments in the patients. Methods: The self-administered survey was conducted in the patients who completed orthodontic treatments living in Seoul and metropolitan areas using Oral Impact on Daily Performances (OIDP) to identify the relevant factors. Data were analyzed with descriptive statistics of variables, independent t-test, one way ANOVA, and multiple regression analysis. Results: From observations of OIDP before, during, and after orthodontic treatment, discomfort associated with three factors including physical, psychological and social ones showed the statistically significant increases during orthodontic treatment than before the treatment; whereas, it was dramatically dropped afterward. Multiple regression analysis to find the influential factors of satisfaction level on orthodontic treatment by setting before, during, and after OIDP as independent variables and satisfaction on orthodontic treatment as a dependent variable revealed that OIDP before orthodontic treatment and after orthodontic treatment significantly affected satisfaction on orthodontic treatment. Conclusions: The above analysis on the change in patients' dental health-related quality of life showed that the quality of life improved after the orthodontic treatment. Accordingly, patients' quality of life and satisfaction level on orthodontic treatment are expected to improve if they strive to maintain healthy dental health through orthodontic treatment.
