The study examined the relationship between the compressed breast thickness and Average Glandular Dose (AGD) among 1,969 outpatients who went through breast X-ray in a university hospital for 10 months from July 1st, 2007 to April 30th, 2008. Then it analyzed the result acquired from 3,900 cases of Cranio-Caudal (CC) view, especially, when the breasts were compressed (13-15daN). The following is the conclusion driven from the relationship analysis. 1. The subjects aged in 40s and 50s were 2,679 out of 3,900 cases and this figure was 68.69% in all. 2. In terms of distribution depending on focus/filter, 41.0% was Mo/Mo, 34.8% was Mo/Rh, and 24.2% was Rh/Rh. 3. In terms of compressed breast thickness depending on focus/filter, the average thickness was 26.91 mm at Mo/Mo, 38.84 mm at Mo/Rh, and 48.80 mm at Rh/Rh. The average thickness of the entire cases was shown to be 36.27 mm. 4. AGD depending on focus/filter was 1.27 mGy at Mo/Mo, 1.55 mGy at Mo/Rh, and 1.42 mGy at Rh/Rh. The average glandular dose of the entire cases was shown to be 1.43 mGy. 5. The relationship of AGD depending on compressed breast thickness at Mo/Mo was y=0.0318x + 0.470 while it was y=0.0206x + 0.709 at Mo/Rh and y=0.0248x + 0.335 at Mo/Rh. It was highly influenced by the compressed breast thickness, however, more variation was detected at Mo/Mo depending on breast thickness.

This study aims to identify the effects: quality of chest compressions, height and weight of pregnant women cardiac arrest while lying $30^{\circ}$ inclined to the left has on the quality of chest compressions administered by 119 EMT. For the purpose of this study, 62 members of 119 EMTs in M, N, S, Y cities and G cities of J province agreed to join in the test and the test was conducted from June 15 to 16 in 2015. Two mannequins (Resusci Anne$^{(R)}$) were used for the study and the chest compression process was recorded with the use of the Laerdal PC Skill Reporting System$^{(R)}$. As a result, it was discovered that for patients with a $30^{\circ}$ left inclination, who were below 170 cm in height and 65 kg in weight, the proper frequency and depth of compression were unsatisfactory. With this in mind, training programs and instruments that can improve the quality of chest compressions depending on a person's (patient's) height and weight should be developed.

The purpose of this paper is to investigate the adequate clothing pressure of upper and lower body foundation garment and subjective assessment of those compressive foundation depending on various wearing conditions. Eighteen women in their 30s and 40s participated in the experiments for this study to evaluate the level of clothing pressure of girdle and waist nipper. Subjects were divided into two groups by the wearing habits of foundation, one is the group of wearing foundation garment 'tightly' and the other is 'loosely', It was found that the group wearing foundation garment 'loosely' was much more sensitive than the group of 'tightly' in everyday life. The adequate pressure of upper foundation, waist nipper was about $1.5{\pm}0.8$ kPa which is lower than that of the lower body foundation, girdle. And at the same time, the sensitivity of the pressure level was higher when subjects are wearing waist nipper compared with wearing girdle. Therefore, precise pattern making process is necessary to meet the adequate level of pressure of the upper body foundation such as waist nipper, specially for those who used to wear clothing loosely.

This study aims to investigate how labour time pressure is associated with leisure selection and managing leisure hours, especially focusing on health related behavior issues. I have employed Time Diary data of 9,891 Korean respondents who were married and living in the cities and metropolitan area (female 51.8%, age range 20-69, average age=45.7). Leisure activities, as dependent variable, which were introduced in time diary data and the amount of time spent for such leisure were estimated. Results show that in time pressing situations(having long labour hours), leisure activities, and the hours spent for leisure tend to suffer. Especially, solitary leisure, like exercise or walking was very likely to sacrifice under time pressure. Moreover, in terms of sports or exercise, results suggest that not only time resource but also social and economic resources seemed to required for actually initiating the activity. Therefore, simply having more time (less tiome for work) may not be enough for promoting exercise for this population. Strategies and social policies that are aiming for promoting healthy behavior needs more closer look on leisure situation and people's desire for optimizing their time.

선진국에서는 선시공 후분양이 일반적이다. 후분양은 소비자가 지어진 주택을 살펴보고 아파트를 살 수 있어 유리하지만 대규모 주택을 짓는 건설사는 사업 초기에 자금 압박이 크다. 시민 사회단체에서는 선시공 후분양이 주택 값을 내릴 수 있는 묘안처럼 이야기하지만 선분양, 후분양 모두 장단점이 있다.

Cardiac arrest is a series of conditions that occur when the heart is stopped, regardless of the cause. Cardiac arrest due to heart disease is included in the cause of death in korea every year and is unpredictable. One of the only ways to save a patient's life when a cardiac arrest is cardiopulmonary resuscitation is to maintain circulation through this procedure. The visual information is transmitted to the brain through the optic nerve. Among them, the mittor can see its movement and its shape, and it can be used for correction and analysis. Therefore compared the quality of chest compressions with visual information using mirrors. There was a significant difference in the mean depth of chest compressions($48.93{\pm}6.76$, $53.86{\pm}4.56$, <0.001), and there was also a difference in compression to relaxation ratio($0.87{\pm}0.13$, $0.96{\pm}0.10$, <0.002). There was also a significant difference in attitude awareness($4.93{\pm}0.85$, $8.14{\pm}1.38$, <0.001).

최근 국내에서 유행하기 시작한 스키니 진(skinny jean)은 혈액순환 장애, 하복부 장기에 가해지는 압력으로 인하여 소화불량, 변비 또는 생리불순 등 여성 건강을 위협하는 의복 종류이다. 본 연구의 목적은 의복의 쾌적성을 측정할 수 있는 척도인 의복압 검사와 스키니 진의 주관적인 착용감 검사 통하여 의복의 기능적인 면에서 인체의 건강에 적합한지 분석하고자 함이다. 사이즈 코리아를 참고하여 선정한 20대 여성의 평균 사이즈에 해당하는, 인지도 높은 3개 브랜드의 청바지를 시료로 사용하여 4명의 피험자에게 착용하게 한 후, 동작을 변화시키며 변화하는 의복압을 측정하고 주관적 감각 평가를 실시하였다. 첫째, 의복압 측정결과, 엉덩이 최대 돌출 부위가 자세와 상관없이 의복압이 가장 높게 나왔고 무릎 부위 Standing 자세에서 sitting down on the floor 자세로 변할수록 의복압이 높게 나왔다. 둘째, 주관적 감각에 대한 평가 결과는 모든 자세에서 허리벨트 부위가 가장 압박감을 크게 느끼는 것으로 나타났다. 의복압과 주관적 감각의 관계분석에 있어서 스키니 진의 대부분의 부위에서 의복압이 높을수록 압박감을 느끼는 것으로 나타났으나 대퇴부 부위는 의복압이 낮은데도 불구하고 압박감을 크게 느끼는 것으로 나타났다.

This study was conducted to examine the differences of the quality of chest compression between 10 cm higher position of rescuer's knee from the bottom and its bottom position during implementation of CPR. It selected randomly subjects out of 66 students who attend the Dept. of Emergency Medical Technology in G college, G metropolitan city as the first grader and divided them into 31 experimental group and 32 control group from Nov. 8 to 9, 2011. Mattress was spread 10 cm higher from the bottom(material: B4 Copy Paper) and on the bottom(material: PVC, size: $185{\times}125{\times}0.65cm$) and only chest compression was conducted for 2 minutes. Experiment was conducted with 1 Resusci Anne mannequin and the results of experiment were recorded with Laerdal PC Skill Reporting System. Data collected were analyzed with $x^2$-test and Fisher's exact probability test using SPSS 14.0 for Window, Mann-Whitney U-test, and Wilcoxon signed rank test. As a result of the study, it was found that 10 cm higher position of rescuer knee from the bottom than the bottom position and group below 170 cm in their height and 65 kg in their weight were more effective in proper depth of chest compression and average chest compression depth.
