Background: After successive trials and failures of various injectable materials such as bovine collagen, polyacryamide, calcium hydroxylapatite, etc., hyaluronic acid (HA) has become the most popular filling material. Many new HA fillers are being produced for the purpose of correcting wrinkles and augmentation of soft tissue. Objectives: This study aimed to test the efficacy, tolerability, and safety of a new HA filler, HA-IDF (Yvoire Classic s touch-up, LG Life Sciences, Inc., Seoul, South Korea) and compare HA-IDF with Restylane (Q-Med, Uppsala, Sweden). Methods: Fifty-eight subjects with visible nasolabial folds (NLFs) were enrolled in a randomized, multi-center, single-blind, active-controlled, matched-pair clinical study. Each subject was injected with HA-IDF in one NLF and Restylane in the other. All participants were assessed for cosmetic change at 2, 10, 18, and 26 weeks. Results: At screening, the average Wrinkle Severity Rating Scale (WSRS) for both right and left NLFs was 3.24±0.43. After 26 weeks, the results were 2.56±0.09 for both groups. There was no significant difference in WSRS scores for wrinkle improvement and in incidence of adverse events for both HA filler treatments. Conclusion: The new HA filler HA-IDF is effective and safe for correcting NLFs.

박찬원(Chan-Won Park),손연규(Yeon-Kyu Sonn),장용선(Yong-Seon Zhang),홍석영(S. Young Hong),현병근(Byung-Keun Hyun),송관철(Kwan-Cheol Song),하상건(Sang-Keun Ha),문용희(Young-Hee Moon) 한국토양비료학회 2010 한국토양비료학회지 Vol.43 No.6

본 연구에서는 1:25,000 정밀토양도 등 가용한 공간자료를 이용하여 작성된 토양유실도를 이용하여 한강 상류지역 10개 중권역 108 소유역에 대하여 토양유실량 평가하고 토지이용별 토양유실 위험지역을 분석하였다. 대상유역 총 토양유실량은 895만 Mg yr<SUP>-1</SUP>으로 예측되었으며, 면적당 평균 토양유실량은 6.1 Mg ha<SUP>-1</SUP>yr<SUP>-1</SUP>이었다. 중소유역 단위로 살펴보면 남한강지역이 북한강지역의 유실량 뿐만 아니라 면적당 유실량이 더 많았다. 이는 북한강 권역의 경우 화강암 및 화강편마암이 주요 모재인 반면에 남한강 권역의 경우 토양모재가 퇴적암지대를 많이 포함있어 토양침식성 인자 (K factor)와 경사 인자 (LS factor)가 상대적으로 높고, 남한강 지역의 경우 농경지 토양이 상대적으로 많이 분포하고 있기 때문으로 판단된다. 대상유역의 토지이용별 연평균 토양유실량을 분석한 결과 산림/초지 > 밭 >> 도심/대지 >> 논 > 과수의 순로 분석 대상유역 중 10.7%를 차지하고 있는 농경지에서 유실되는 토양의 추정량은 41.3%이였으며, 이중 6.2%면적을 차지하는 밭이 40.6%으로 44.2%의 산림/초지와 비슷한 수준이었다. 한강상류지역 토양유실 위험성 평가시 분포형 토양침식지도와 항공사진을 비교한 결과 토양유실에 대한 공간인 정보를 확실하게 보여주고 있으며, 토양침식위험성은 남한강권역의 남한강 상류 (1001), 평창강 (1002), 충주댐 (1003) 권역에서 각각 토양침식위험성이 “보통”이상으로 높은 지역이 각각 8.7%, 7.9%, 7.8%로 평균인 5.9%보다 높았으며, 이에 대한 보전방안이 강구될 필요가 있고 판단된다. This study was conducted to evaluate soil erosion risk with a standard unit watershed in the upper Han river basin using the spatial soil erosion map according to the change of landuse. The study area is 14,577 ㎢, which consists of 10 subbasins, 107 standard unit watersheds. Total annual soil loss and soil loss per area estimated were 895 × 10<SUP>4</SUP> Mg yr<SUP>-1</SUP> and 6.1 Mg ha<SUP>-1</SUP> yr<SUP>-1</SUP>, respectively. A result of analysis with a subbasin as a unit showed that annual soil losses and soil loss per area in Namhan river basins was more than in Bukhan river ones. Predicted annual soil loss according to the landuse ranked as Forest & Grassland > Upland >> Urban & Fallow area > Paddy field > Orchard. Upland area covered 6.2% of the study area, but the contribution of total annul soil loss was 40.6% and that of Forest & Grassland was 44.2%. As a evaluation of soil erosion risk using the spatial soil erosion map, we could precisely conformed the potential hazardous region of soil erosion in each unit watersheds. The ratio of regions, graded as higher “Moderate” for annual soil loss, were respectively 8.7%, 7.9% and 7.8% in 1001, 1002 and 1003 subbasins in Namhan river basin. Most landuse of these area was upland, and these area is necessary to establish soil conservation practices to reduce soil erosion based on the field observation.

송영하 호남대학교 정보통신연구소 1998 정보통신연구 Vol.8 No.-

Developing of media industry, customers are easily to get a various information directly rather than the previous time, their attitude of purchasing patterns are has been changed more difficult and speed up the way of seek for a rationale patterns as well. To correspond these kind of change, ECR(Efficient Consumer Response) has been introducing recently. A domestic distribution and manufactories have been adapt many concepts and introducing, applying and developing into their business. ECR should have a unknown concepts for us, however it will be concept which we have to make a very familiar terms by ourselves such as TQM(Total Quality Management), BPR(Business Process Reengineering) and ERP(Enterprise Resource Planning). Like an old English proverbs "Early birds catch the worms", it will be a same sort of things here in distribution industry. I would like to suggest that idea of the possibility of introducing ECR concepts into the domestic market: First, the change of way of thinking. Second, cope with subsidiary company. Third, a construct of system and education. As above, a rapid of change in distribution industry, ECR which expects that a possible visible succeed and to jump into the next further steps, if we take a consider of ECR range and its field, it will regard to go beyond your limits.

This study was carried out to obtain the basic data on salted and fermented damsel fish(Jari-Jeot), one of the important traditional marine foods in Cheju-Do. and also to seek salt lowering method for the development of a new local tourist food. The results are as follows : The best organoleptic results were obtained after 60 days' fermentation for 25.0, 12.5 and 10% of salt-added group, and around 45 days for 7.5 and 5% of salt-added group. In raw fish ingredient IMP was abundant which marked 17.7 μmole/g while in fermented fish hypoxanthine was predominant but ATP and ADP were not detected after 30 days' fermentation. Sixteen kinds of free amino acids were detected and identified in Jari-Jeot instead of 17 kinds of those in raw sample. The abundant amino acids in Jari-Jeot after 60 days' fermentation were lysine. alanine, glutamic acid, glycine and leucine, and those were consisted of approximately 60% of the total free amino acids. During fermentation the content of TMAO was decreased gradually and no TMAO was detected after 75 days' fermentation while that of TMA was increased during fermentation up to 45 days' and decreased afterwards. The fatty acid of low-salt Jari-Jeot was composed of 31.9% of saturated acids, 13.2% of monoenoic acids and 54. 9% of of polyenoic acids. While the content of EPA in polyenoic acids was 1.9%, that of DHA was 23.0%. In order to lower salt concentaration of fermented damsel fish, additon of Pediococcus halophilus culture as a starter together with 10-12.596 of salt, 4-5% of KCI, and 2% of glucose gave as good quality as traditionally made Jari-Jeot.

病院看護人力에 대한 勤務時間表作成에 관한 考察

河英洙,宋英璇 梨花女子大學校 韓國生活科學硏究院 1982 韓國生活科學硏究院 論叢 Vol.29 No.-

Since the hospitals are labor intensive industries which are composed of various professional personnels, the success of hospital management depends upon management of manpower. Nursing services, as the largest user of labor resources, is part and parcel of the hospital management. In this review we examined various types of the nurse manpower scheduling which are becoming major issues in the nurse manpower management. Furthermore; we examined optimal core level(OCL) nurse staffing through a case study which was held at Providence Hospital in U.S.A. Few studies were conducted until now about hospital nurse manpower management in Korea. Nurse scheduling is traditionally conducted in many hospitals, by decentralized staffing which may utilize resources less efficiently and consequently make cost containment more difficult. It may be desirable to develop the rational nurse manpower model through experimental study and detailed analysis of the various types of nurse scheduling in Korea.

송영호,하동명,정국삼 한국화재소방학회 2004 한국화재소방학회논문지 Vol.18 No.1

감용제 limonene을 이용하는 EPS 자원 재활용 공정에 있어서, limonene - EPS 혼합 액체의 저장 · 취급시의 화재위험성 평가에 대한 기초 자료로 제시하고자 혼합물의 농도 및 시료량의 변화에 따른 최저발화온도를 측정하였고, 발화와 비발화 영역을 비교하였다 발화온도를 예측하는데 있어서 가장 과학적인 원리로서 이용되고 있는 발화 지연 시간, 활성화 에너지 및 발화온도의 관계식을 선형회귀분석을 이용하여In t= 0.704/T -5.819로서 제시하였다. 또, 가연성 혼합물의 농도 변화에 따른 발화위험성을 예측하기 위하여 혼합물의 농도와 발화온도의 관계식을 비선형회귀분석을 이용하여 T_(m)=248.32+69.27X+172.60X²로서 제시하였다. 그 결과, 발화 지연 시간과 발화온도와의 관계식 및 혼합물의 농도와 발화온도와의 관계식에 의해서 limonene - EPS혼합물의 발화온도의 추정이 가능하게 되었다. In the reutilization process using limonene, the organic solvent to reduce volume of EPS, the AIT was measured with the variation of concentration and volume of mixture, in order to present the fund-mental data on the fire hazard assessment of limonene - EPS mixture at storage and handling. And ignition zone was compared with non-ignition zone. The equation related to AIT, activation energy and ignition delay time, used by the most scientific basis for predicting AIT values, was suggested using linear regression analysis as In t = 0.704/T - 5.819. And the equation related to concentration of mixture and AIT was also suggested to predict ignition hazard of combustible mixture using nonlinear regression analysis as T_(m)= 248.32 + 69.27X + 172.60X², It enabled to predict ignition temperature according to variation of ignition delay time and concentration of mixture by the suggested equations.
