  • MiTS 통신 프로토콜은 선박에서 발생하는 다양한 정보의 통합 처리 및 교환을 위하여 제안된 표준이다. 일반적인 통신 프로토콜과 유사하게 MiTS 통신 프로토콜도 상태 천이로 명세되어 있다. 이러한 통신 프로토콜의 구현에는 많은 노력과 시간이 필요하므로, 이를 경감할 수 있는 체계적인 설계 및 구현 방법이 요구된다. 이러한 요구에 적합한 방법론으로 디자인 패턴을 들 수 있다. 본 논문에서는 이러한 디자인 패턴을 적용하여 MiTS 통신 프로토콜을 객체지향적으로 설계하고 C++로 구현한 결과에 대하여 기술한다.

  • 선박 내의 통합 정보 관리를 위한 MiTS 아키텍처는 게이트웨이, 미들웨어 서버 그리고 어플리케이션과 같은 세 개의 구성 요소로 이루어져 있다. 게이트웨이는 선박 내의 여러 장비에서 발생되는 정보를 수집하여 가공하는 기능을 가지고, 미들웨어 서버는 가공된 정보를 통합하여 데이터베이스에 저장하는 기능을 가지며, 어플리케이션은 수집되어 저장된 정보를 사용자에게 시각적으로 표시하는 기능을 가진다. 본 논문에서는 미들웨어 서버의 서비스를 게이트웨이와 어플리케이션이 제공받을 수 있도록 해주는 국제 표준 IEC61162-4 series 기반의 미들웨어 서버의 서비스 모듈을 제안하고 구현 및 검증한다.

  • MiTS 통신은 선박 내에서 발생하는 다양한 형태의 정보를 시스템 상호 간에 교환하기 위한 프로토콜이다. 또한, 이러한 정보 교환을 위한 약 30여 가지의 특수한 메시지 포맷도 정의되어 있다. 따라서, MiTS 통신 프로토콜을 따르는 시스템의 구축을 위해서는 이러한 메시지를 일관성 있게 처리해야 한다. 본 논문에서는 이를 위한 메시지 처리 모듈의 설계와 구현을 제시한다. 또한, 구현된 모듈의 테스트 결과를 제시한다.

  • Arsenic exposure is a serious health hazard worldwide. We have previously established that it may result in immune suppression by upregulating Th2 cytokines while downregulating Th1 cytokines and causing lymphocytic death. Treatment modalities for arsenic poisoning have mainly been restricted to the use of chelating agents in the past. Only recently have combination therapies using a chelating agent in conjunction with other compounds such as anti-oxidants, micronutrients and various plant products, been introduced. In the present study, we used T11TS, a novel immune potentiating glycopeptide alone and in combination with the sulfhydryl-containing chelator, mono-iso-amyl-dimarcaptosuccinic acid (MiADMSA) as a therapeutic regimen to combat arsenic toxicity in a mouse model. Results indicated that Th1 cytokines such as TNF-${\alpha}$, $IFN{\gamma}$, IL12 and the Th2 cytokines such as IL4, IL6, IL10 which were respectively downregulated and upregulated following arsenic induction were more efficiently restored to their near normal levels by T11TS alone in comparison with the combined regimen. Similar results were obtained with the apoptotic proteins studied, FasL, BAX, BCL2 and the caspases 3, 8 and 9, where again T11TS proved more potent than in combination with MiADMSA in preventing lymphocyte death. The results thus indicate that T11TS alone is more efficient in immune re-establishment after arsenic exposureas compared to combination therapy with T11TS+MiADMSA.

  • This study analyzes time variability of the normalized difference vegetation index (NDVI), the leaf area index (LAI) and surface temperature (Ts) estimated from AVHRR data collected from across the Korean peninsula from 1981 to 1994. In the present study, LAI defined as vegetation density, as a function of NDVI applied for the vegetation types and Ts defined by the split-window formulation of Becker and Li (1990) with emissivity of a function of NDVI, are used. Results of the inter-annual, intra-annual and intra-seasonal variabilities in Korea show: (1) Inter-annual variability of NDVI is generally larger in the southem and eastern parts of the peninsula than in the western part. This large variability results from the significant mean variation. (2) Inter-annual variability of Ts is larger in the areas of smaller NDVI. This result shows that the NDVI play a small role in emissivity. (3) Inter-annual variability of LAI is larger in the regions of higher elevation and urban areas. Changes in LAI are unlikely to be associated with NDVI changes. (4) Changes in NDVI and Ts are likely dominant in July and are relatively small in spring and fall. (5) Urban effect would be obvious on the time-varying properties of NDVI and Ts in Seoul and the northern part of Taejon, where NDVI decreases and Ts increases with a significant magnitude.

  • TS-DP2 is a recombinant human granulocyte colony stimulating factor (rhG-CSF) manufactured by TS Corporation. We conducted a four-week study of TS-DP2 (test article) in repeated intravenous doses in male and female Sprague-Dawley (SD) rats. Lenograstim was used as a reference article and was administered intravenously at a dose of $1000{\mu}g/kg/day$. Rats received TS-DP2 intravenously at doses of 250, 500, and $1000{\mu}g/kg/day$ once daily for 4 weeks, and evaluated following a 2-week recovery period. Edema in the hind limbs and loss of mean body weight and body weight gain were observed in both the highest dose group of TS-DP2 and the lenograstim group in male rats. Fibro-osseous lesions were observed in the lenograstim group in both sexes, and at all groups of TS-DP2 in males, and at doses of TS-DP2 $500{\mu}g/kg/day$ and higher in females. The lesion was considered a toxicological change. Therefore, bone is the primary toxicological target of TS-DP2. The lowest observed adverse effect level (LOAEL) in males was $250{\mu}g/kg/day$, and no observed adverse effect level (NOAEL) in females was $250{\mu}g/kg/day$ in this study. In the toxicokinetic study, the serum concentrations of G-CSF were maintained until 8 hr after administration. The systemic exposures ($AUC_{0-24h}$ and $C_0$) were not markedly different between male and female rats, between the administration periods, or between TS-DP2 and lenograstim. In conclusion, TS-DP2 shows toxicological similarity to lenograstim over 4-weeks of repeated doses in rats.

  • Sensitivity to 6-n-propylthiouracil (PROP) tasting predicts sensitivity to food qualities as well as rejection of some strong tasting foods. Using consumer rejection threshold (CRT) method, this study aimed to assess whether systematic changes in the taste intensities of familiar foods would lead to earlier rejection of these products by PROP tasters than by PROP non-tasters. Subjects rated the intensity of PROP solution and were divided into tasters (Ts) and non-tasters (NTs). And Ts were further divided into medium-tasters (MTs) and super-tasters (STs). Difference thresholds and CRTs were then evaluated for caffeine in coffee, citric acid in orange juice, and for NaCl in beef soup. For each food, Ts were more sensitive to variations in tastants than NTs. Ts also rejected more bitter coffee, more sour orange juice, and less salty beef soup more readily than did NTs. Comparisons among NTs, MTs, and STs gave fewer clear differences.
