This study explored the method of determining the appropriate size of the workforce according to the assessment of the workload of medical technologists (also called medical and clinical laboratory technologists, and medical and clinical laboratory scientists) in order to present a standard production model for the appropriate manpower in blood collection rooms. The eleven university hospitals selected for this study had between 600 and 2,000 beds. The 14-steps standard blood collection time was 4 minutes and 8 seconds for the outpatients aged between 20 to 60 years old (57%) except for children and the elderly (43%). Assuming that there were 8 hours per day for mechanically collecting blood, the maximum number of blood donations by one clinical laboratory scientist was analyzed to be 100 cases. In conclusion, it is appropriate to have fewer than 100 cases of daily blood collection by a medical technologist engaged in blood collection. Since the proper number of blood collection workers (100% of blood collection work)=the number of annual working days/(one day's work hours/time per case)×the number of working days per year, then the proper number of blood collection workers (one day's work hours)=the number of working days per year/100×the number of working days).

본 연구에서는 발효기간 중 SAM 생성량 증진김치의 최적조건을 개발하기 위해 배추김치의 재료별 및 제조법에 따른 발효기간 중의 SAM 함량 변화를 측정하였다. 발효가 진행됨에 따라 모든 김치군의 pH는 발효초기에는 급격히 감소하다가 후기에는 pH $4.2{\sim}4.3$으로 비슷하게 나타났다. 산도는 pH와 비슷한 경향을 보이면서 발효초기에는 급격히 감소하다가 후기에는 서서히 증가하는 경향을 보였다. SAM 함량은 가장 기본적인 재료로만 제조한 표준(A)김치는 가장 낮게 나타났고, SAM이 검출되는 원 부재료에 SAM 함량이 많은 김치가 SAM 함량도 높게 나타났다. 모든 김치군 중 I김치가 가장 높은 SAM 함량을 나타냈으며, 김치별 SAM 함량이 가장 높은 발효시점은 A, K김치는 pH $4.6{\sim}4.9$, 산도 $0.38{\sim}0.57$0.57, D, H김치는 pH 6.3, 산도 $0.24{\sim}0.27$, E, G김치는 pH $6.1{\sim}6.6$, 산도 $0.05{\sim}0.14$0.14, B, C, F, I, J김치는 pH $4.3{\sim}5.3$, 산도 $0.45{\sim}1.02$에서 나타났다. 따라서 대부분의 김치는 적숙기시점이 되었을 때 B, E, G, H김치는 초기발효 때부터 SAM 함량이 높게 나타났다. 또한 발효가 진행됨에 따라 SAM 함량은 감소하는 경향을 보였다. 따라서 연구결과 주재료인 채소류와 젓갈의 함량비를 적절히 제조하여 최적의 SAM 생산능력의 발효시점과 김치맛에 영향을 끼치지 않는 관능적으로 적합하고 SAM 생성이 보다 효과적으로 유도되는 최적의 조건에 대한 실험들이 추가적으로 필요하다고 판단된다.

This study established the efficient system that retrieves the 3D model by using a statistical technique called the function of discriminant analysis. This method was suggested to search index, which was formed by the statistics of 128 feature vectors including those scope, minimum value, average, standard deviation, skewness and scale. All of these were sampled with Osada's D2 method and the statistics as a factor effecting a change turned the value of discriminant analytic function into that of index. Through the primary retrieval on the model of query, the class above the top 2% was drawn out by comparing the query with the index of previously saved class from the group of same models. This method was proved an efficient retrieval technique that saved its procedural time. It shortened the retrieval time for 3D model by 57% faster than the existing Osada's method, and the precision that similar models were found in the first place was recorded 0.362, which revealed it more efficient by 44.8%.

Adsorption equilibrium and intraparticle diffusion characteristics of benzene, toluene, and xylene vapors on activated carbon and zeolite 13X were investigated. Static adsorption experiments were carried out under the pressure range of 0.01~0.07 bar while changing the adsorption temperature to 293.15 K, 303.15 K, and 313.15 K, respectively. Adsorption equilibrium was analyzed by Langmuir, Freundlich and Toth models. The adsorption energy was 5.26~31.0 kJ/mol representing physical adsorption characteristics. The maximum adsorption capacity on activated carbon was the largest for benzene, and the smallest for xylene. Toluene was in between. In the case of zeolite 13X, the maximum adsorption capacity was the largest for xylene, and the smallest for benzene as opposed to activated carbon. The effective diffusion coefficients of gas adsorbate were measured to be about $10^{-5}{\sim}10^{-4}cm^2/s$, and increased with temperature. As the pressure increased, the effective diffusion coefficients were decreased. The dependence of effective diffusion coefficients on temperature and pressure was greater in zeolite 13X particles than in activated carbon. Therefore, it is necessary to express the diffusion coefficients as a function of pressure in order to predict the precise dynamic behavior of the adsorption process using zeolite 13X where the pressure fluctuation occurs abruptly.

Screening of Biologically Active Essential Oils from Ligusticum tenuissimum. Kim, Min-Hae, Young-Gil Kim, Jin-Ha Lee, Keo-Pyo Hong, Jung-Ki Hong, Young-Joon Kong, and Hyeon-Yong Lee*. Division of Food and Biotechnology, Kangwon National University, Chunchon 200-701, Korea, 1 Regional Crop Development Station, Kangwon Agricultural Research & Extension Services, Chunchon 200-150, Korea-The biological activities of the crude essential oils from Ligusticum tenuissimum and the control(phthalic anhydride) were compared. About 60% of the growth of MCF7, A549, and Rep3B cells were inhibited by adding 1.0 mg/ml of the crude essential oils and below 40% was observed by the control. Cytotoxicity on human normal lung cell(IMR90) was scored as 34.4% for the crude oil and 26.4% for control, respectively. It was found that the crude essential oils were more effective than the control in anti mutagenecity tested by both Rec-assay and CRG V79 cells. The growth of human T-cell(Jurkat) was enhanced up to 1.21 times by adding the crude essential oil compared with the control. 50% of a-glucosidase activity was inhibited by both the crude essential oil and the control. ACE activities were inhibited 80.1 % and 65.3% by adding 1.0 mg/ml of the crude oil and the control, respectively. The higher enhancement of glutathione-S-transferase activity was observed in the crude oil than those in the control: 301 % v.s 234% at 1.0 mg/ml of the treatment. Thrombolytic activity was measured as 42.9% and 28.6% for the crude oil and the standard, respectively. The effect of the oil on the nerve cells PCI2, was observed as follows: the neurite of PCl2 cells was lengthened up to 255 /-lm longer than 205 /-lm of control. The number of neurite-bearing cells were about two times higher than control. The survival ratio of the crude essential oil was also increased up to 56.4% which was about two fold higher than in control.

The Demand Response Market is a nation-wide power and energy management program of electric power demand response operated by KPX (Korea Power eXchange). Therefore, any savings could be determined by KEPCO's AMR(Automatic Meter Reading) data. However, the customers and the service providers participating in the market could not know the real time value due to the 15 minute or even more delayed AMR data communicated. Here, a new concept of a smart box has been introduced and demonstrated to provide the real time saving values compared to the current KEPCO's AMR data approach.
