In this study, emission characteristics of volatile odorant species released from urine samples were investigated in relation to two key variables: [1] storage conditions before sampling and [2] incubation conditions during sampling. To this end, 20 offensive odorants were quantified by four different analytical systems and then sorted according to seven functional groups. It is indicated that benzene (B), styrene (S), isobutyl alcohol (i-BuAl), butyl acetate (BuAc), butyraldehyde (BA), isovaleraldehyde (IA), and valeraldehyde (VA) did not contribute to urine odor because their concentration levels were measured below detection limits in all samples. On the other hand, emission concentrations of toluene (T), methyl ethyl ketone (MEK), methyl mercaptan ($CH_3SH$), carbon disulfide ($CS_2$), and ammonia ($NH_3$) were generally higher than other compounds. In terms of odor intensity (OI), $CH_3SH$ and $NH_3$ showed the largest OI values in the range of 2~4. According to t-test (storage approach and urine temperature), the results of T, $CS_2$, and $NH_3$ were statistically distinguished from each other in terms of differences in sampling temperature. Likewise, the emissions of certain odorants from urine samples were affected by changes in sample treatment conditions to a degree.

Objectives : It has been suggested that obesity in childhood may lead early menarche and rapid bony maturation. The purpose of this study is to investigate correlation between bone maturation and obese degree in childhood in Korea. Methods : Height, body weight, BMI, percent body fat were taken 138 patients. Ultrasonic scan was taken through calcaneous of the right foot to evaluate bone age. $DA({\Delta}age)$ was calculated from the difference of bone age and chronological age, and it was used in correlation with obese degree. Results : 1. The average age of patients was $11.91{\pm}2.86$ years old in boys, $11.44{\pm}2.27$ years old in girls. 2. The average BMI was $20.92{\pm}4.53kg/m2$ in boys, $19.76{\pm}4.05kg/m2in$ girls, and average percent body fat was $25.13{\pm}8.23%$ in boys, $27.66{\pm}5.95%$ in girls. 3. The average OI(osteo index) was 37.88 in boys, 36.64 in girls, and average bone age was $12.00{\pm}2.61$ years old in boys, $11.81{\pm}2.11$ years old in girls. 4. There was significant correlation between $DA({\Delta}age)$ and PBF in boys, but no significant correlation with BMI(p<0.05). 5. There was significant correlation between $DA({\Delta}age)$ and PBF, BMI in girls(p<0.01). 6. There was significant correlation between RA and OI(p<0.01).

Recently, companies and organizations are becoming increasingly dependent on external resources to keep their competitive advantages under the turbulence of global business environmental changes. Therefore, they focus on the paradigm 'Open Innovation (OI)' which is reported as a convincing strategy to improve competitive advantage in terms of budget and time-to-market. The management of Incheon International Airport Corporation (IIAC) also considers the introduction of Open Innovation not only to adapt the business environmental changes but also to be devoted its social role as a public corporation. In this paper, we describe how we derived the promotion tasks for the introduction of OI and prioritized the tasks, performing our research on the IIAC Open Innovation. For these purposes, this research conducted the following three steps; the first stage for the analysis of current situation on the IIAC Open Innovation, the second stage for the elicitation of promotion tasks, and the last stage for the prioritization of the promotion tasks. In the first stage, critical success factors (CSFs) for open innovation introduction were derived from different research papers and case studies. In the following stage, promotion tasks were elicited from the IIAC based on the CSFs. In the last stage, the promotion tasks were evaluated on the base of criteria by using Analytic Hierarchy Process (AHP). And then the promotion tasks were grouped by the result of the evaluation. In this case, thirteen promotion tasks were derived for open innovation, ten promotion tasks except three inevitable promotion tasks were evaluated, and then they were grouped into four categories based on the importance-possibility analysis.

A Fabry-Perot interferometer (FPI) for mesospheric observations was installed at King Sejong Station ($62.2^{\circ}S$, $58.9^{\circ}W$) in Antarctica in 2017. For the initial validation of the FPI measurements, we compare neutral wind data recorded with the FPI with those from a Meteor Radar (MR) located nearby. The overall characteristics of the FPI and MR winds of both OH 892.0 nm (87 km) and OI 557.7 nm (97 km) airglow layers are similar. The FPI winds of both layers generally match the MR winds well on the observed days, with a few exceptions. The correlation analysis of the FPI and MR wind data shows that the correlation coefficients for the zonal winds at 87 and 97 km are 0.28 and 0.54, respectively, and those for the meridional winds are 0.36 and 0.54, respectively. Based on the assumption that the distribution of the airglow emissions has a Gaussian function with respect to the altitude, we calculated the weighted mean winds from the MR wind profile and compared them with the FPI winds. By adjusting the peak height and full width at half maximum of the Gaussian function, we determined the change of the correlation between the two winds. The best correlation for the OH and OI airglow layers was obtained at a peak height of 88-89 km and 97-98 km, respectively.

서론 : 완치 목적의 절제술을 시행 후 국소재발된 직장암환자에 대한 방사선치료 결과 및 생존율에 미치는 예후인자에 대해 평가하고자 하였다. 대상 및 방법 1982년 7월부터 1996년 5월까지 인제대부속 백병원과 한양대부속병원 방사선종양학과에서 국소재발된 직장암으로 방사선치료를 시행받은 총 28명의 환자를 대상으로 치료결과에 대한 후향적 분석을 시행하였다. 남녀비는 14:14이었고, 연령분포는 31세에서 72세 사이로 나타났다(평균 연령:54.5세). 일차 수술 후 국소 재발까지의 기간은 4개월에서 46개월로 관찰되었다(중앙값:10개월). 방사선치료는 총 27Gy에서 64.8Gy(median; 51.2Gy)가 조사되었다. 50.OGy 이하로 조사된 환자는 모두 11례로 나타났으며, 17례에서 50.OGy 이상이 조사되었다. 결과 : 증상완화는 전체 환자 중 17례(60.7%)에서 관찰되었고, 출혈 및 통증을 호소한 환자의 경우 각기 100%와 40%%에서 증상완화가 관찰되었다. 증상완화정도의 방사선 조사량에 따른 차이는 관찰되지 않았다. 방사선치료 시작 일부터 전체 환자의 중앙생존기간은 16.7개월이고, 2년 및 5년 생존율은 20.1%, 4.1%로 나타났다. 생존율에 대한 예후 인자를 분석해 보았을 때, 단일변량분석에서 일차 수술 후 국소재발까지의 기간이 유일한 예후인자로 나타났다. 그 외 연령, 성별, 임상수행능력정도, 재발부위, 초기병기, 초기 수술방법, 원격전이여부, 방사선조사량 등은 유의한 인자로 관찰되지 않았다. 즉 일차 수술 후 국소재발까지의 기간이 1년 이상인 경우에서 1년 이하에 비해 의미있게 높은 생존율이 관찰되었다(2년 및 5년 생존율:42.0%, 8.4% vs 0.0%)(P<0.05). 다변량분석에서도 생존율과 연관된 예후 인자로는 일차 수술후 국소재발까지의 기간만이 의미있게 관찰되었다. 결론 : 본 연구에서는 방사선치료가 국소재발된 직장암환자에서 병변으로 인한 증상을 완화시키는 데 효과적이며, 일부의 환자에서는 장기간의 생존이 가능함을 알 수 있었다. 그러나, 전체적으로 2년 및 5년 생존율이 저조하게 나타났고, 일차 수술 후 국소재발까지의 기간이 생존율에 영향을 미치는 것으로 관찰되어, 향후 국소 재발된 직장암 환자에서 생존율의 향상을 위한 효과적인 치료법에 대한 연구가 필요하겠고, 더불어 초기 치료 후 국소재발방지를 위해 부가치료에 대한 적극적인 연구가 우선되어야겠다.

목 적 : 급성 폐손상이 있는 소아에서 혈액 응고 과정에서 중요한 역할을 하는 AT-III의 예후인자로서의 의미를 확인하고자 대상 환자에서 진단 초기의 AT-III 값을 측정하고 사망여부에 따라 AT-III 값을 비교 분석하고 지금까지 알려진 여러 예후인자들과 비교 분석하였다. 방 법 : 2004년 6월부터 2005년 12월까지 18개월 동안 서울대학교병원 소아중환자실에 입원한 198명의 환자 중 급성 폐손상의 정의를 만족하고 기계적 환기요법을 받은 21명의 환자를 대상으로 인구의학적인 변수와 기저질환, 초기 안정화 이후의 호흡지수들, 기계적 환기요법의 여러 설정 등을 측정하였다. 중환자실 입원 24시간 이내의 PRISM-III 점수, LIS 점수를 측정하였고 입원 3시간 내의 AT-III 값을 측정하였다. 사망여부에 따라 두 군으로 분류한 후 예후인자를 비교분석하였고, PRISM-III 값과 AT-III 값에 대해서는 상관관계와 회귀분석을 함께 시행하였다. 단변수 분석에서 사망여부에 따라 통계적으로 유의한 변수에 대해서 중회귀 분석을 시행하여 상대위험도를 측정하였다. 결 과 : 18개월 동안 198명이 입원하였고 21명의 환자가 진단기준을 만족하였다. 남자가 13명(61.9%)였고 연령은 5(1-14)세였다. 급성 폐손상이 발생한 장소가 병원이 아닌 경우가 33.3%였고 기저질환이 폐 병변인 경우가 66.7%였다. 대상 환자 중 AT-III 값이 70% 이하인 경우가 10명(42.9%)이였고 8명의 환자가 사망하여 사망률은 38.1%였다. 사망에 따른 두 군 간의 비교에서 초기 안정화 이후 동맥혈 pH와 $PaO_2/FiO_2$는 사망한 환자군에서 유의하게 더 낮았고, OI와 호기말 양압은 사망한 환자군에서 유의하게 더 높았다. 폐 유순도는 사망한 환자군에서 유의하게 더 낮았다. LIS와 PRISM-III는 사망한 환자군에서 모두 유의하게 높았고 AT-III는 사망한 환자군에서 유의하게 더 낮았다. AT-III와 PRISM-III 값은 유의한 상관관계를 보였다. 중회귀분석에서 PRISM-III, LIS, OI는 모두 다른 변수에 독립적으로 유의한 사망의 위험인자였으며 70% 미만으로 정의한 AT-III 감소는 급성 폐손상 환자에서 다른 변수에 독립적으로 사망의 유의한 위험인자였다(OR 2.725, 95% CI 1.284-4.119). 결 론 : 급성 폐손상으로 기계적 환기요법을 시행 받은 소아환자를 대상으로 한 본 연구에서 초기 AT-III 값은 PRISM-III 값과 유의한 상관관계를 보였으며, 또한 사망한 환자군에서 AT-III 값이 유의하게 더 낮았고 이것은 다른 위험인자의 영향을 보정한 상태에서도 독립적인 사망의 위험인자였다. 이로써 AT-III가 급성 폐손상의 유의한 조기 예후 예측인자라는 것을 확인하였으며 향후 급성 폐손상/급성 호흡부전증후군 환자에서 응고장애를 정상화 할 수 있는 처치들이 예후를 향상시킬 수 있을 가능성을 제시하였다.
