The purpose of this study is to analyze relationship between the level of maintenance management service and occupant satisfaction in office buildings. In order to ensure whether the level of maintenance management service corresponds with occupant satisfaction to indoor environment quality(IEQ), we evaluated maintenance management service through surveys of managers and investigated occupant satisfaction by the questionnaire in seven office buildings. Based on this research, it is found that when the level of maintenance management service increased until 60%, occupant satisfaction to IEQ rose with the level of maintenance management service, but when the level of maintenance management service was over 60%, occupant satisfaction didn't become higher. Also, we found factors affected to occupant satisfaction to IEQ and these were not only environmental factors such as temperature, humidity, air flow and indoor air quality but also Help Desk service such as response time to request and attitude.

The purpose of this study is to analyze relationship between service level of the management system and occupants' satisfaction in office buildings. In order to ensure whether service level of maintenance management system corresponds with occupants' satisfaction level, we evaluated maintenance service level through surveys of managers and investigated occupants' satisfaction by the questionnaire in 7 office buildings. Throughout analysis, it was found that not only maintenance service level does not correspond with occupants' satisfaction level, but as maintenance service level becomes high, occupants' satisfaction level becomes lower.

This paper focuses on the relationship between thermal environment and thermal acceptability based on complaints. Thermal environment factors and occupants complaints were measured by "thermal complaints voting device" fabricated for this study on each work station in eight offices in summer. The key results are that each hot complaints and cold complaints occurred in a wide range of temperature than we expected and there was an overlap between temperature of hot and cold complaints. As a temperature range occupants experienced in their office was broader, there was more distinction of average and midium between cold and hot complaints. Also, when occupants less complained, they had higher thermal satisfaction and self-assessed productivity.

Purpose : To suggests the standardization of respiratory function and how Abdomen Fat CT examination influences on the diagnosis of obesity variation depending on respiration. Materials and methods : The target was 40 adults of Abdomen Fat CT examination was performed among the adults visited the above hospital for March 2015 ~ May 2015. Experimental group was divided into 4 subgroups according to Body Mass Index (BMI) to scan the inspiration image and expiration image for 2 times of Fat CT with CT such as Brilliance iCT(256 slice MDCT, Philips healthcare, Cleveland, OH, USA) and to let the subgroups breath from the abdomen. For the examination, the author lets scan covered L4~6 on the basis of Umbilicus and estimated BMI with Aquarius iNtuition Version 4.4(A workstation) and IntelliSpace Portal(ISP) Version 4.0(B workstation) to calculated VFA, VFA, VSR (Visceral vs. Subcutaneous Fat Rate). Also, the author compared and analyzed the images with a statistic program such as SPSS/WIN 21.0 and T-test, and determined that the result related to the images were significant statistically in case the result was p<0.5. Results 1. A workstation : In underweight group, VFA reduced 21.9±17.8㎠ (21.9±13.9%)(p<0.05). SFA increased -3.2±8.3㎠ (3.8±9.3%), the difference was not significant, VSR decreased 0.28 ±0.26㎠ (23.9±16.9%)(p<0.05). In normal weight group, VFA decreased 21.7±7.1㎠ (19.4± 8.4%)(p<0.05), SFA increased -1.5±6.4㎠ (1.3±8.9%), the difference was not significant, VSR decreased 0.21±0.1㎠ (21.4±9.2%) (p<0.05).In overweight group, VFA decreased 21.2±21.9 ㎠(15.2±16.2%)(p<0.05), SFA increased -0.4±3.5㎠(0.1±3.1%), VSR decreased 0.16±0.22㎠ (14.9±18.3%), the difference was not significant. In obesity and extreme obesity group, VFA decreased 25.7±21.3㎠ (14.8±11.9%)(p<0.001), SFA increased -0.7±7.7㎠ (0.6±3.3%), the difference was not significant, VSR decreased 0.17±0.15㎠ (15.1±13.2%)(p<0.001). 2. B workstation : In underweight group, VFA decreased 43.9±40.5cc (24.4±13.3%)(p<0.05), SFA increased -9.5±8.7cc (4.2±3.1%), the difference was not significant, VSR decreased 0.28 ±0.27cc (27.2±14.7%)(p<0.05). In normal weight group, VFA decreased 47.0±12.9cc(22.9 ±6.7%)(p<0.05), SFA increased -12.2±3.3cc (3.9±0.9%), the difference was significant, VSR decreased 0.23±0.14cc (23.5±7.5%)(p<0.05).In overweight group, VFA decreased 49.4±36.8cc (19.0±12.8%)(p<0.001), SFA increased -15.5±6.9cc (5.4±4.3%) (p<0.01), VSR decreased 0.20 ±0.15cc (23.0±12.8%)(p<0.01).In obesity and extreme obesity group, VFA decreased 58.0 ±49.9cc (16.4±10.9%)(p<0.05), SFA increased -10.7±16.2cc (2.6±2.9%) (p<0.001), VSR decreased 0.18±0.15cc (18.4±12.1%)(p<0.001). Conclusion : In estimating BMI of profile images for 4 groups in accordance with BMI, VFA showed a significant percentage as 18.4% (p<0.05), and SFA showed an insignificant percentage as 1.45% during inspiration period and expiration period. In estimating BMI of volume image, VFA showed a significant percentage as 20.7% (p<0.05), and SFA showed 2 insignificant percentages as 4.2% and 3.9%, respectively, in underweight group and normal weight group during inspiration period and expiration period. Also, in overweight group and extreme obesity group, VFA and SFA showed 2 insignificant percentages as 5.4% and 2.6%, respectively, during inspiration period and expiration period (p<0.01). In estimating BMI with Abdomen Fat CT, VFA was more decreased during expiration period than during inspiration period. Therefore, the standardization of respiratory function is required by all means for exact BMI estimation. 목적 : Abdomen Fat CT 검사시 호흡에 따른 비만도 변화가 진단에 미치는 영향을 알아보고, 호흡 조절의 표준화를 제시하고자 한다. 대상및방법 : 2015년 3월부터 5월까지 본원을 내원한 환자 중 Abdomen Fat CT를 시행한 성인 40명을 대상으로 하였다. CT장비는 Brilliance iCT(256 slice MDCT, Philips healthcare, Cleveland, OH, USA)를 이용하여,실험 대상군을체질량 지수(Body mass Index, 이하 BMI)에 따라 4개의 군으로 나누고 호흡 유형은 복식호흡으로 흡기와 호기 두번의 Fat CT를 시행하였다. scan 범위는 Umbilicus를 중심으로 L4~5로 하고, 각각의 scan한 영상은 Aquarius iNtuition Version 4.4(이하 A workstation)와 IntelliSpace Portal(ISP) Version 4.0(이하 B workstation)을 사용하여 비만도를 측정하였다. 측정 방법은A workstation 을 이용하여 1장의 단면 영상으로, B workstation 을 이용하여 8장의 volume영상으로 만들어Hounsfield number -250 ~ -50에 속하는 총 복부 지방면적(total abdominal fat area)을 복부와 배부의 복막을 경계로 안쪽을 내장 지방 조직(visceral fat tissue), 바깥쪽을 피하 지방 조직(subcutaneous fat tissue)으로 나누어 내장지방면적(Visceral Fat Area : VFA), 피하지방면적(Subcutaneous Fat Area : SFA)을 측정하였고, 측정한 값들을 이용하여 내장지방/피하지방 면적 비(Visceral-Subcutaneous Fat Ratio, 이하VSR)를 계산하였다. 그리고 통계 프로그램 SPSSWIN 21.0와 T-test를 이용하여 비교 분석 하였으며, p<0.5인 경우에 통계적으로 유의 하다고 판정하였다. 결과 : 1. A workstation : 저체중 군에서 VFA는 흡기보다 호기에서 평균면적 21.9±17.8㎠, 21.9±13.9% 감소로 유의한 차이가 있었다(p<0.05).

B workstation : 저 체중 군에서 VFA는 흡기보다 호기에서 평균면적 43.9±40.5cc, 24.4±13.3% 감소로 유의한 차이가 있었다(p<0.05). SFA는 평균면적 -9.5±8.7cc, 4.2±3.1% 증가로 유의한 차이가 없었고, VSR은 0.28±0.27, 27.2±14.7% 감소로 유의한 차이가 있었다(p<0.05). 정상 체중 군에서는 VFA는 흡기보다 호기에서 평균면적 47.0±12.9cc, 22.9±6.7% 감소로 유의한 차이가 있었고(p<0.05), SFA는 -12.2±3.3cc, 3.9±0.9% 증가로 유의한 차이를 보이지 않았다. VSR 은 0.23±0.14,23.5±7.5% 감소로 유의한 차이가 있었다(p<0.05).과 체중 군에서 VFA는 흡기보다 호기에서 평균면적 49.4±36.8cc, 19.0±12.8% 감소로 유의한 차이가 있었다(p<0.001). SFA는 -15.5±6.9cc, 5.4±4.3% 증가(p<0.01), VSR은 0.20±0.15, 23.0±12.8% 감소로 유의한 차이가 있었다(p<0.01). 비만 및 고도비만 군에서는 VFA는 흡기보다 호기에서 평균면적 58.0±49.9cc,16.4±10.9% 감소로 유의한차이가 있었고(p<0.05), SFA는 -10.7±16.2cc, 2.6±2.9% 증가(p<0.001), VSR 은 0.18±0.15, 18.4±12.1% 감소로 유의한 차이가 있었다(p<0.001). 결론 : BMI에 따른 4개의 군에서 단면 영상의 비만도 측정은 흡기와 호기의 VFA가 18.4%로 유의한 차이가 있었고(p<0.05), SFA는 1.45%로 유의한 차이가 없었다. 볼륨 영상의 비만도 측정은 VFA가20.7%로 유의한 차이가 있었고(p<0.05), SFA는 저 체중 군과 정상 체중 군에서는 4.2%와 3.9%로 유의한 차이가 없었으나 과 체중과 비만 및 고도비만 군에서는 5.4%와 2.6%로 유의한 차이가 있었다(p<0.01). Abdomen Fat CT를 이용한 비만도 측정에서 흡기시호기보다 내장지방면적이 증가함을 알 수 있었다. 그러므로 정확한 비만도 측정을 위해서는 호흡의 표준화가 반드시 필요할 것으로 사료된다.

Inflammatory bowel disease (IBD), comprised of two major disorders, Crohn disease (CD) and ulcerative colitis (UC), are chronic inflammatory disorders that can affect the gastrointestinal tract. It is known that IBD commonly presents with extraintestinal manifestations (EIMs). Children and adolescents with IBD are often at risk for suboptimal bone health because of undernutrition, delayed puberty, and prolonged glucocorticoid (GC) use. The authors report a case of a child with IBD and osteolysis in this report.
