Considering that the X-ray apron used in the department of radiology is also used in the department of nuclear medicine, the study aimed to analyze the shielding rate of the apron according to types of radioisotopes, thus ${\gamma}$ ray energy, to investigate the protective effects. The radioisotopes used in the experiment were the top 5 nuclides in usage statistics $^{99m}Tc$, $^{18}F$, $^{131}I$, $^{123}I$, and $^{201}Tl$, and the aprons were lead equivalent 0.35 mmPb aprons currently under use in the department of nuclear medicine. As a result of experiments, average shielding rates of aprons were $^{99m}Tc$ 31.59%, $^{201}Tl$ 68.42%, and $^{123}I$ 76.63%. When using an apron, the shielding rate of $^{131}I$ actually resulted in average dose rate increase of 33.72%, and $^{18}F$ showed an average shielding rate of -0.315%, showing there was almost no shielding effect. As a result, the radioisotopes with higher shielding rate of apron was in the descending order of $^{123}I$, $^{201}Tl$, $^{99m}Tc$, $^{18}F$, $^{131}I$. Currently, aprons used in the nuclear medicine laboratory are general X-ray aprons, and it is thought that it is not appropriate for nuclear medicine environment that utilizes ${\gamma}$ rays. Therefore, development of nuclear medicine exclusive aprons suitable for the characteristics of radioisotopes is required in consideration of effective radiation protection and work efficiency of radiation workers.

Purpose: This study aimed to evaluate the current status of hospice palliative care facilities in Korea. Based on the result, we attempted to suggest activation plans of hospice palliative in Korea. Methods: To conduct a survey, we obtained a list of hospice palliative care facilities from related agencies and academic societies. A survey was conducted from February, 2009 to March, 2009. The survey was consisted of general characteristics of organizations, manpower, facilities & equipments, and so on. In addition, we used data from Statistics Korea to estimate the number of beds required and the bed occupancy rate. Results: Total number of facilities responded to the questionnaire were 53. Forty-two facilities were general hospitals and 6 facilities were clinics among the total 53 facilities, and 18.8% of facilities were located in Seoul, Incheon and Gyeonggido. Overall bed occupancy rate was rather low as 21.9%, and there were 4 provinces where bed occupancy rates were 0%. Deaths in hospice palliative care facilities during 2008 were 6.3% of total deaths from cancers. As for the questions about the financial status of facilities, 86% of facilities were answered financial insufficiency. Also more than half of the facilities gave financial insufficiency as the reason for shortage of human resource supplies and inability to achieve the standard for authorization by the government. Facilities answered in order to activate the hospice palliative care, governmental support is needed, mostly in financial support (71.2%), donation tax deduction (43.1%), and setting up a public utility foundation (23.5%). Conclusion: This study showed low rates of hospice palliative care use and bed occupancy in Korea. Regional variance in bed occupancy rate was significantly high. As a roadblock for these problems, most of the facilities cited financial insufficiency. Therefore, there must be some action plans to boost financial support to activate hospice palliative care in Korea. Finally, efforts to improve these circumstances including lack of understanding about hospice and palliative care, are needed as well.

Purpose: This study was to identify the death recognition, meaning in life, and death attitude of participants in the death education program. Methods: A survey was conducted, and 205 data were collected. Descriptive statistics, ${\chi}^2$-test, ANOVA, and Duncan test were used. Results: 1) The followings were the characteristics of death recognition shown by the participants. Over half of the participants said that they had given some thoughts on their deaths, that they had agreeable view on death acceptance, and that diseases and volunteer works made them think about their deaths. Moreover, suffering, parting with family and concerns for them, etc. were the most common reasons for the difficulty of accepting death. As for 'the person whom I discuss my death with', spouse, friend, and son/daughter were the most chosen in this order. Lastly, the funeral type that most of the participants desired was cremation. 2) The means of meaning in life and death attitude were $2.92{\pm}0.29$ and $2.47{\pm}0.25$, respectively. There were significant differences between health status, meaning in life and death attitude. 3) A significant positive corelationship was found between meaning in life and death attitude (r=0.190, P=0.001). Conclusion: For an effective death education program that would fit each individual's situation, an educational content that can make a person understand the meaning of his or her life and death, includes knowledge to lessen the fear and anxiety of death, and helps a person heal from the loss of a family member is absolutely necessary.

Purpose: This study is to understand how community members perceive past life recollection and preparation for death. Methods: Using a questionnaire, we surveyed 160 adult residents of one of the districts (gu) in Seoul, Korea. Descriptive statistics were used. Results: Participants chose their 30s and 40s as the most difficult time in their lives. The most painful experience was "an illness of a family member", followed by "trouble with a spouse", and "trouble with children". As for the most difficult social experience, "sense of loss in life" was ranked the highest. Personally, the happiest time was "accomplishment of a goal", while it was "happiness through children" in family relationship and "contribution to society through my career" in social life. As for the most regrettable experience, personally "having lived without purpose" was the highest, "not meeting my parents' expectation more" in family relationship; "not providing sufficient education" in relationship with children; "not having an occupation that I wanted" in work life, and "lack of social skills" in social life. More than 87% of the surveyed showed a positive attitude about the system of the do not resuscitate (DNS) order. For a situation where participants were supposed to have an incurable disease, "I want to be notified of the true condition" and "I want to write a will and advanced directives" ranked high, receiving more than 3.1 points out of 4. Conclusion: These results demonstrate the need for death education to provide people with an opportunity to accept their regrettable experiences in the past as part of their life. Also, this study suggests the importance of writing advanced directives for people to prepare for "death with dignity" how it can help their decision to be better respected.

This study was intended to describe women's weight controlling by creating a hypothetic model on the weight adjustment behavior and by examining a cause and effect relationship, and to contribute to countermeasures for practicing their promotion of health and improving the quality of life through creating a predictable model. The subject of study was women who utilize the beauty shop located in Seoul, Busan and Daegu and the study period was 12 weeks from July 10 to September 30 in 2004. Gathered 1093 person's general specialty related with weight adjustment and analyzed covariance to prove the hypothesis using statistics compiled from authentic sources. Also proved coincidence of the hypothetical model. Exogenous variables of the hypothetical model are composed of recognition of her body shape, fatness level, age, stress, and self-respect. Endogenous variables are health- control mind, recognized health state, self-efficacy, intention, and behavior of weight adjustment. There were 5 measured variables for exogenous variable(x). There were 8 measured variable(y) for exogenous variable. And coincidence $x^2=297.38$, standard $x^2(x^2/df)=7.08$, GFI=0.962, AGFI=0.917, NFI=0.875, TLI=0.794, CFI=0.889, RMSEA=0.075. The result of hypothesis had an epoch-making record that 20 out of 27 hypothesis was proved positive way. Generally weight adjustment has been highly seen in housewives, the married and the old age. Health control mind seems to be high as fatness level, age, and self-respect are high and low stress. Recognized health state is high as age and self-respect are high and low stress. However, it is not much related with recognition of her body shape and fatness level. If age, self-respect, health control mind, recognized health state and self-efficacy are high intention of behavior is also high, but intention of behavior has no relation with recognition of her body shape, fatness level and stress. If fatness level, age, self-respect, health control mind, recognized health state and self-efficacy and intention of behavior are high, execution of weight adjustment will be high. However, recognized health state and stress has no influence for weight adjustment. To increase the coincidence of hypothesis and take a simple model I modified a model and then I got the coincidence $x^2=215.62$, standard $x^2(x^2/df)=6.34$, GFI=0.970, AGFI=0.931, NFI=0.902, TLI=0.901, CFI=0.915, RMSEA=0.070. This result is a bit better than original hypothetical model's so that this model might be more suitable. In this modification model, the factors of weight adjustment seems to be high according to this order self-efficacy, recognized health state, age, intention, health control mind, self-respect, fatness level and stress. With this result I suggest ; 1. Enforcement of IR that everybody can be controlled weight adjustment herself and continuous education, which is related with regular habit (food, exercise, restriction of a favorite food and behavior training etc.) is also needed. 2. Because self-efficacy is influenced to execution of weight adjustment specific program which can increase self-efficacy should have to develop and we need to utilize it to take care of herself. 3. To protect fatness and be active weight adjustment the peculiar program including the concept of self-respect, recognized health state, health control mind and intention must be developed and not only women but also all of people should be educated. 4. This hypothetical model is forecasting women's weight adjustment behavior and can be utilized for fundamental data to increase those people's health.

After world war II Japanese life expectancy has been improved remarkably, and reached the highest level in the world around late 1970's. The life expectancy of Korean has also shown tremendous improvement in recent years with about 20 year's gap from the Japanese. The reason of rapid improvement of life expectancy can be explained by changes in the structure of cause of death due to health system, living standard, social welfare, health behavior of individuals and so on. Korean in Japan is placed under different situations from both Korean in Korea and Japanese in these regards, and expected to show different picture of cause of death pattern. The objective of this study is the comparision of changing patterns of cause of death of three population groups, Korean in Japan, Korean in Korea and Japanese, and to investigate the reasons which effect to the structural difference of mortality cause with special emphasis on health ecological aspects. One of the major limitations of the Korean causes of death statistics is the under-registration which ranges about 10% of the total events, and inaccuracy of the exact cause of death. Some 20% of registered deaths were unable to classify by ICD. However, it is concluded that the Korean data are evaluated as sufficient to stand for over-viewing of trends of cause of death pattern. The evaluation is done by comparing data from registration and field survey over the same population sample. Population data of Korean in Japan differ between two sources of data; census and foreigner's registration. Correction is done by life table method under the assumption that age-specific mortality pattern would accord with that of the Japanese. The crude death rate was lowest among Korean in Japan, 5.7 deaths per 1,000 population in 1965. The crude death rates of Korean in Japan and Japanese are increasing recently influenced by age structure while Korean in Korea still shows decreasing tendency. The adjusted death rate is lowest among Japanese, followed by Korean in Japan, and Korean in Korea. The leading causes of death of Korean in Korea until 1960's was infectious diseases including pneumonia and tuberculosis. The causes of death structure changed gradually to accidents, neoplasm, hypertensive disease, cerebro-vascular disease in order. The main difference in cause of death between Korean and Japanese if high rate of liver diseases and diabetes for both Korean in Japan and Korea. A special feature of cause of death among Korean in Korea is remakably high rate of hypertensive disease, which is assumed to be caused by physicians tendency in choosing diagnostic categories. The low ischemic heart disease and high vasculo-cerebral disease are the distinctive characteristic of the three population groups compared to western countries. Specific causes of death were selected for detailed sex, age and ethnic group comparisons based on their high death rates. Cancer is the cause of death which showed most dramatical increase in all three population groups. In Korea 20.1% of all death were caused by cancer in 1990 compared with 10.5% in 1981. Cancer of the liver is the leading cause of cancer death among Korean in Japan for both sexes, followed by cancer of the lung and cancer of the stomach, while that of Korean in Korea is cancer of the stomach, followed by cancer of the liver and cancer of the lung for male. Causes of infant mortality were examined among the three population groups since 1980 on yearly bases. For both Japanese and Korean in Japan, leading cause of death ranks as conditions originating in the perinatal period, congenital anomalies, accidents and other violent causes. Trends since 1980 for these two population groups in the leading cause of infant mortality showed no changes. On the contrary, significant changes in leading cause of death structure in Korea were observed : the ranking of leading cause of death in 1981 were congenital asnomalies, pneumonia bronchitis, infectious disease, heart disease, conditions originating in the perinatal period, accident and other violent causes ; in 1990 the ranking shifted to congenital anomalies, accident, pneumonia bronchities, conditions originating in the perinatal period, infectious disease. The mortality rate by congenital anomalies in Korea continuously grew than any other causes. Larger increase ocurred during the 1990's

The aim of this study was to investigate the issue in obese children with a high probability of leading to precocious puberty for they have more advanced skeletal maturation compared to normal children in order to contribute to the health of obese children by identifying the relationship between physique and physical fitness according to their skeletal maturation. A total of 243 obese children between the ages of 10-13 were enrolled as subjects, and the skeletal maturation, which symbolize indicators of biological maturation, were evaluated by using the TW3 method after hand-wrist radiographs, thus classified the skeletal maturation level into retarded group(n=70), normal group(n=128), and advanced group(n=45). A stadiometer and InBody 270 (Biospace, Korea) were used to measure 3 components in physique. A total of 7 components in physical fitness, which included muscular strength, muscular endurance, flexibility, power, cardiovascular endurance, balance, agility, were measured as well. Descriptive statistics and one-way variable analysis (ANOVA) were conducted for data processing using SPSS 25.0, and Duncan's multiple-range method was used for post hoc analysis; and it was considered significant at the level of P< .05. Analysis results of this study may be summarized as follow. First, height and weight in physique factors according to the skeletal maturation between the retarded, normal, and advanced groups in males and females were highly significant. Second, physical fitness comparison according to the skeletal maturation in males were statistically significant in muscular strength, power, and agility whereas muscular strength and balance were statistically significant in females.

This study investigated stress and the extent of climacteric symptoms in mid-life men, and examined their relationship in order to better understand the stress and climacteric symptom experiences of mid-life men, and thereby attempted to offer basic materials for the development of a health improvement program that may help increase the quality of life of mid-life men. Three hundred mid-life men whose ages were between 40 and 59 and resided in the Seoul area were subjects of this study. The data were analyzed with the SAS PC program using descriptive statistics to analyze subjects' general characteristics and variables of stress and the extent of climacteric symptoms of the subjects. The relationship between stress and climacteric symptoms were examined by the Pearson Correlation Coefficient, and stress and the extent of climacteric symptoms in relation to the general characteristics were analyzed by T-test and ANOVA. The study conclusions are as follows: 1. Subjects general characteristics The average, age of the subjects was 46 and 47.0% of them reported ages between 40 and 45. Of the subjects, 98% were married. In marriage satisfaction, those who were generally satisfied with their married life comprised 62.0% of the subjects. In terms of level of education, 95.7% were educated above the high school level. In occupational background, 59.7% had occupations related to technologies. As for religion, 42.7% had no religion. In number of children, 67.3% had 2 children. In residential status, 79,3% were living in their own homes. In terms of living arrangements, 87.7% of the subjects were living in the form of nuclear families. 2. Stress and the extent of climacteric symptoms The level of stress was scored as $2.94{\pm}0.74$, and considering that the overall examination score is $27.16{\pm}1.32$, the subjects' stress level was not viewed as particularly high. The average score of the extent of climacteric symptoms was $35.37{\pm}0.27$. The extent of sub-domains of climacteric symptoms included skeleton symptoms ($39.37{\pm}2.81$), joint pain ($39.16{\pm}3.66$), vasomotor symptoms ($35.39{\pm}3.01$), other symptoms ($36.99{\pm}3.02$), psychological symptoms ($34.68{\pm}3.01$), urogenic symptoms ($35.03{\pm}3.27$), and cardiovascular symptoms ($33.70{\pm}2.78$). 3. General characteristics in relation to the stress level The subjects' general characteristics that were significantly related to the level of stress were marriage status (F=4.38, p=.001), marriage satisfaction (F=4.56, p=.001), educational background (F=2.68, p=.012), and age (F=2.48, p=.033). 4. General characteristics in relation to the level of climacteric symptoms The subjects' general characteristics that were significantly related to the level of climacteric symptoms were educational background (F=3.26, p=.007), age (F=2.58, p=.027), marriage status (F=2.62, p=.025), and marriage satisfaction (F=2.78. p=.032). 5. The correlation between stress and climacteric symptoms The subjects' level of stress and climacteric symptoms were significantly related to each other (r=0.578, p=0.000). The subjects' level of stress was correlated with sub-domains of the climacteric symptoms including psychological symptoms (r=0.579, p=0.000), joint pain (r=0.479, p=0.000), skeleton symptoms (r=0.477, p=0.000), other symptoms (r=0.467, p=0.000), vasomotor symptoms (r=0.4615, p=0.000), cardiovascular symptoms (r=0.458, p=0.000), urogenic symptoms (r=0.401. p=0.000). In summary, the climacteric symptoms suffered by mid-life men are positively correlated with their level of stress. In addition, the climacteric symptoms were affected by the level of stress.

Information on the limits of treatment could allow for more rational treatment Planning and better results after treatment. From this point of view, this article has attempted to discuss the limits of orthodontic tooth movement. A relatively wider range of tooth movement is expected after Class III surgical-orthodontics than after conventional orthodontic treatment in general. The purposes of this Paper were: first, to evaluate the reliability of teeth position measuring gauge; and second, to elucidate the limits of orthodontic tooth movement. Dental casts of fifty-fine subjects were analyzed by using Set-up model checker (InVisitec Co., Korea) before and aster the Class III surgical-orthodontic treatment. The changes of maxillary and mandibular dental arch widths were also measured from the canines to the second molars. To test the inter-examiner reliability, randomly selected casts were measured by another examiner. Descriptive statistics and paired t tests were used to explain the tooth movement during treatment. The results showed a relatively good reliability of measuring instruments and a very diverse range of tooth movement. Collective changes by the orthodontic tooth movement evaluated in Class III surgical-orthodontics allowed for a suggestive interpretation of specific treatment patterns. Arch width changes during the inter-arch coordination were mainly the result of tipping in both buccal segments. Based on the results of this study, the possibility of a change in dentition as a result of orthodontic treatment should be understood in order to launch a well-organized plan of treatment.
