The optimal medium composition for the production of carotenoid pigment from Haloarcular sp. EH-1 as a dietary for fishes were 1.0% sucrose, 1.0% yeast extract, 25% sodium chloride, 0.3% sodium citrate, 0.2% potassium chloride, 2.0% magnesium sulphate, 0.002% ferric sulphate(pH7.0). The incubation temperate, aeration rate and agitation speed were 40℃, 100ml medium/500ml vol. shaking flask, and 180 rpm/min. The carotenoid pigment production was highest after 5 days of incubation with the light.

The wide spread of multimedia sysrem deands a large viewing display device which can inform a message to many peoples in open area. This paper is about the design and simulating of a large viewing digital multi-wision control ASIC(Application Specific Integrated Circuit). In this paper. the digital multi-vision ASIC has one channel of imput cideo signal wihich is compliance with CCIR-656 specification and four channels of output video signal which are compliance with CCIR-601 specificarion. It has 2 operating mode. The one is the pass-thro;ugh mode. input vido signal goes to output video signal without any change, and the another one is the expension mode, input video signal is expended by from 2 to 16 times into output video signal. In expension mode. awindow could be programmed and only the input video signal in the window is expended. The 0.6 micron CMOS sEA OF Gate is used to design the ASIC in amount of about 23,000 gates, and it is simulated at 48MHz.

Objectives : Separation and reunion is common experiences in our life but enduring unwanted early-life separation from family members may be a distressful event. This study was executed to observe emotional resolution in the subjects who eagerly desire and experience reunion with their families after long-lasting separation. Methods : Thirty subjects who have participated in the reunion program of the Korean Broadcasting System (KBS) from April 2005 to July 2005 were interviewed to assess their demographic characteristics and memories about separation. Their anxiety and depressive mood were assessed using Spielberger’s State-Trait Anxiety Inventory, Beck Depression Inventory, Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale before the family reunion. At the time of the reunion, psychological states of 14 participants who were able to meet their family members were assessed again using the same assessment tools and the follow-up assessment was performed for one possible case at 7 months after the reunion. Results : The depression and anxiety levels of most subjects were significantly decreased after the reunion. Standardized T scores of their state-anxiety were mostly in abnormal range before the reunion but most of their anxiety levels were reduced within normal range after the reunion. Duration of education was negatively correlated with trait-anxiety level and duration of separation respectively even though trait-anxiety levels were not directly correlated with duration of separation. Emotional acceptability about childhood separation tended to contribute to the increased anxiety level. Conclusion : This is the first study to assess psychological distresses of the Korean people who have suffered from long-lasting separation with their families. The results in this study suggest that the eagerly desired reunion after long-lasting separation from family may have a resolutive effect for emotional distress, further study will be needed for larger population suffering from early-life separation.

Breast cancer in women pose a problem, and it can be difficult at times to evaluate the possibility of the cancer recurrence in node negative early cancer. The reliable prognostic markers are needed in breast cancer management to help clinicians identify the patient with the high risk of recurrence and arrive at more rational decisions for proper treatment. In order to investigate the prognostic significance of bcl-2, an immunohis-tochemical staining was performed in 35 tissue sections from paraffin blocks of primary breast cancer. Bcl-2 positivity was 43%. No relation could be observed between bcl-2 expression and known prognostic factors(tumor size, lymph node metastasis state, histologic grade, and nuclear grade), There was strong relation between bcl-2 expression and estrogen receptor positivity (ER) (P〈0.05). No relation is found between bcl-2 expression and c - erbB - 2 expression. These results suggest that bcl-2 expression is associated with a favorable prognostic factor(ER) but it is of no value as independent prognostic factor to the clinician in identifying the patients with high risk of recurrence.

The bed expansion characteristics have been investigated in a fluidized bed (0.1 m I.D., 2.4 m height) with variations of the gas velocity (0.015 - 1.0 m/s), the static bed height (0.1, 0.2m) and the type of particle (Geldart group A, B and D). The ratio of bed expansion increased as the gas velocity increased. However, it decreased with an increase of the static bed height. It also decreased in order of Geldart group A, B and D particles at the same excess gas velocity and static bed height. A correlation on the bed expansion has been proposed on the basis of the present experimental result.

Bronchopleural fistula and chronic empyema are the difficult problems in the thoracic surgery field. We experienced 3 cases of chronic empyema and complicated bronchopleural fistulas treated with muscle flap and concomitant thoracoplasty. The causative primary diseases were pulmonary tuberculosis and bronchiectasis. All the three cases have failed to control the chronic empyema and bronchopleural fistula with conventional method such as closed or open drainage and Eloesser flap after lobectomy. The unresponsive infection on bronchopleural fistula and pleural space was well controlled after muscle flap with thoracoplasty. Complete decortication, closure of bronchopleural fistula as much as possible and coverage of closed fistula with good vascularized tissue are the essential factors for the success of operation on chronic empyema and bronchopleural fistula. The results of operations were satisfactory and the respiratory function was well preserved or improved in one patient. But, the contour of chest wall was deformed in patient with extensive concomitant thoracoplasty.

A sensibility measurement system that can measure human sensibility at the automobile cabin environment is developed in this paper. Five kinds of sensors that can measure temperature, humidity, oxygen, CO_(2), and HC gas concentrations are used in this system. Sensibility indexes are defined for each sensor datum, and then those are linearly combined to make a total human sensibility index. A stand-alone system is manufactured using a one-chip microprocessor, and simple controls are showed with LEDs. This system was tested for performance in automobile cabin environment and showed good reliability.

능동 규칙의 실행 의미를 반영한 종료 분석

능동 데이터베이스는 미리 정의된 규칙(rule)에 의해 규칙에 대응하는 사건이 발생하면 자동으로 트리거 되어 조건을 평가하고 조치를 수행한다. 이러한 능동 규칙은 연속적으로 서로 다른 규칙을 트리거 할 수 있고 그로 인해 종료하지 못하고 무한한 순환적 동작을 반복할 가능성이 있다. 그러므로 규칙의 비종료를 방지하고 규칙 처리를 미리 예측하기 위한 목적으로 규칙의 종료에 관한 연구가 수행되었지만 매우 다양하고 복잡한 상황에 대해 정확한 규칙종료가 이루어지지 않는다. 또한 규칙의 여러 사건 형태에 따라 분석 결과가 달라질 수 있음에도 불구하고 일반적으로 사용되고 있는 복합사건의 규칙과 규칙 실행의 적용시점을 나타내는 before, after 규칙을 포함한 종료분석방법은 제시되고 있지 않다. 그러므로 이 논문에서는 규칙 종료의 정확한 분석을 위해 복합사건의 규칙과 before 또는 after 규칙을 고려하고, 규칙간에 형성되는 비활성화 관계를 이용하여 그래프로 표현한 비활성화 그래프를 기존의 트리거 그래프와 결합한 종료 분석 방법 및 절차를 제시한다. In the active database, whenever an event occurs, active rules with the matching event specifications are triggered, if it's condition is satisfied, then action of that trigger rule will be executed. Because these rules may in turn trigger other rules, the set of rules may be triggering each other indefinitely. This non-termination works have been proposed to predict its behavior in advance. However, most of the proposal is not concluded termination on certain situations. Besides, it is not included various event types and "before" or "after" rules. In the paper, we propose that this termination analysis method is captured by triggering and deactivation graph which is including rule execution semantics to exact rule termination analysis.
