본 연구는 식물성 플랑크톤의 1차 생산력에 대한 N:P ratio의 영향을 분석하기 위해 “영양염 첨가실험(NEBs)”을 실시하였다. 영양염 첨가실험(NEBs)에 의한 N:P Ratio의 영향은 대청호에서 측정된 수질데이터와 비교분석하였다. 단기 영양염 첨가실험 결과, 인 (P)을 첨가한 처리군들 (N:P Ratio=5, 15, 20, 30)에서의 1차 생산력의 반응이 대조군 (Control)과 인(P)을 첨가한 처리군 (N:P Ratio=80, TV), 질소(N)를 첨가한 처리군(N:P Ratio=150, TVI)에서보다 높았다. 또한 질소 (N)를 처리한 처리군에서는 대조군과 모든 처리군에서보다 1차 생산력의 반응이 유의하게 작았다. 영양염 첨가실험의 결과, 식물성 플랑크톤의 성장에 인이 제한영양염으로 작용하고 있었으며, 질소첨가 (Spiking N)는 식물성 플랑크톤의 성장을 억제한 것으로 사료된다. 대청호의 영양염 변이 분석 결과, 최소 N:P Ratio에서 엽록소-a의 최대농도가 나타났고, N:P Ratio는 식물성 플랑크톤의 성장에 대한 핵심 조절자로 사료되었다. 본 연구결과를 종합해 볼 때, N:P Ratio가 식물성 플랑크톤의 성장을 조절하는 핵심 인자로 작용 할 것으로 사료된다.

Treponema denticola is the best studied oral spirochete and numerous studies have shown that it is strongly associated with periodontitis and expresses several putative virulence factors. In this study, we report on a surface protein of T. denticola, Td92, which is homologous to Tp92 of Treponema pallidum, an agent of syphilis. Immunofluorescence assay and immunogold labeling with anti-Td92 Ab revealed that Td92 had surface-exposed epitopes. And Td92 was capable of binding to fibronectin and KB cells, an oral epithelial cell line. In addition, Td92 could enter the KB cells. These results indicate that Td92 is a fibronectin-binding protein which can bind to and internalize into the host cells, facilitating the virulence of T. denticola.

  Future war needs a lot of changes for military organization. In this circumstance, it is importance the role of the Military Equipment Command Separation (MECS). In case of Korea Marine Corps, in spite of being MECS, Marine Corps has formed supply chain

This paper was concerned about case study for preventing WMDSs(Work-related Musculoskeletal Disorders) by using Thinking Process of TOC(Theory Of Constraints), Unfortunately, the number of WMDSs are rising steadily in auto-part manufacturer. These WMDSs have on worse and worse influence not only on the competition of enterprise but on the life quality of a worker. The research results are helpful to establish the preventing WMDSs and improvement of workplace environments for small-medium sized auto-part company.

Companies adopted a program called Six Sigma, in order to make fundamental changes in the way the company operated to fulfill customers' expectations. Six Sigma reduces the occurrence of defects. This approach derives the overall process of selection the right projects based on their potential to improve performance metrics and selection and training the right people to get the business results. However, in the course of Six Sigma process steps, companies are in the face of problems. This study is to solve the problems using TP(Thinking Process) of TOC(Theory of Constraints). TOC is methodology for solving key problem in system which is called Constraints. Nowadays, its application is going to be wide and its concept is being implemented. In this paper, it is showed possibility of application TOC to Six Sigma.

The steady potential flow about a TP 620 hydrofoil, flying in air above a dynamic water surface. is calculated by the one dimensional theory as the clearance-to-length ratio tends to very small. The characteristics on water surfare effects of air supported TP 620 hydrofoil over water are compared NACA 4412, NACA 66 and plate. respectively. It is found that using the TP 620 hydrofoil is superior lift coefficients. Moreover for trailing edge shape of the hydrofoil, high lift coefficients at 1 Fmn can be obtained.

이상으로부터 비 cavitation 정상상태인 박용 TP620 익형의 점성의 영향에 의한 배제두께를 고려했을 경우의 익특성을 요약하면 다음과 같다. 1. 점성의 영향에 의한 압력분포는 전연부분에서는 부압의 피크가 사라지고 후연부에서는 겉보기 익두께 생성에 의해서 potential 유동의 상이형을 보이는 것은 burst 유동으로 후연부분 유동에 큰 영향이 없음을 알 수 있다. 2. 배제 두께 및 운동량 두께는 층류부분보다 난류부분의 증가비율이 크고 속도 구배가 0인 천이점 부근에서 불연속으로 인해 점성력에 의한 초생 cavity의 존재 가능성을 배제 투께 a 및 운동량 두께 분포로부터 알 수 있다. 3. 점성에 의한 배제 두께의 생성으로 원익형의 단면은 사실상 증가하며 이를 고려한 경우 익성능이 약간 감소했다.

Chomsky (2007, 2008, 2013) proposes that T has no substantial features and it inherits all the relevant grammatical features from C. More specifically, in the C-to-T feature inheritance approach T does not have its own inherent Case feature and inherits the nominative Case feature from C. This claim can be supported if there is a C-less finite TP and the subject of the TP cannot be assigned Case by T in the construction. In this paper I propose that there is indeed a construction in which C-less TP occurs and the there-construction is a case in point. Furthermore, this paper shows that the subject of the C-less TP cannot be assigned Case within the TP projection, providing empirical evidence for the C-to-T feature inheritance approach.

According to the so-called 'NP/DP parameter,' languages with articles may project both DP and NP in the nominal domain, while those without can have at most NP with the DP layer missing (Fukui (1988), Chierchia (1998), Bosković (2008), inter alia). Recently, extending this line of reasoning to the clausal domain, Bosković (2010) argues that article-less languages, such as Hindi, Japanese, Korean and Turkish, do not have TP in the clausal architecture. This paper aims to closely examine whether Bosković's claim, referred to as 'TP parameter,' is tenable. We show that careful reconsideration of TP parameter is required since it undergenerates: i.e., there are a number of empirical data in Korean, an article-less language, which it wouldn't be easy to explain unless TP is postulated. The data revealing problems for the parameter include (i) the dependency of licensing negation upon TP in key-ha-la imperatives; (ii) the availability of sentential negation and a verbal predicate in a resulting clause in resultatives; and (iii) the asymmetry between clausal ellipsis and replacement of the pro-form kulehkey.
