본 저자는 앞선 연구에서 제안한 SSVS 방법을 이용하여 한 양적형질에 대한 연관분석에 있어, QTL에 가까이 있는 관련된 표지유전자들의 위치를 정하고자 한다. 본 논문에서는 QTL에 연관되어 있고 동시에 서로 연관되어 있는 몇 가지 표지유전자들을 대상으로 하는데, 이 유전자 좌위들의 i.b.d. 값들을 상호 상관이 있는 예측변수로서 고려하여, SSVS 방법으로 분석한다. 두개의 QTL에 강하게 연관되어 있는 표지유전자들 만을 동시에 고려한 분석의 결과, QTL에 가장 가까이 위치한 표지 유전자가 다른 유전자들보다 더 분명하게 양적형질과의 관련성을 보여주었다. SSVS를 이용한 상호 상관이 있는 표지 유전자들의 분석의 결과는 전통적인 다중회귀분석을 이용한 결과와 거의 일치했다. 본 모의실험을 바탕으로, 복합 양적형질에 대하여 서로 연관된 다중의 표지유전자들을 동시에 연관분석을 수행하는 데에 SSVS 방법이 상당히 유용하다고 결론 내린다.

A crucial first step in the planning of any scientific experiment is to evaluate an appropriate sample size to permit sufficient statistical power to detect the desired effect. In this study, we investigated the optimal sample size of quantitative trait locus (QTL) linkage analysis for simple random sibship samples in pedigreed chicken populations, under the variance component framework implemented in the genetic power calculator program. Using the program, we could compute the statistical power required to achieve given sample sizes in variance component linkage analysis in random sibship data. For simplicity, an additive model was taken into account. Power calculations were performed to relate sample size to heritability attributable to a QTL. Under the various assumptions, comparative power curves indicated that the power to detect QTL with the variance component method is highly affected by a function of the effect size of QTL. Hence, more power can be achievable for QTL with a larger effect. In addition, a marked improvement in power could be obtained by increasing the sibship size. Thus, the use of chickens is advantageous regarding the sampling unit issue, since desirable sibship size can be easily obtained compared with other domestic species.

In the global manufacturing industry, digital transformation is emerging as an important issue for companies to improve productivity and strengthen industrial competitiveness. The government and shipbuilding companies drive research and development to attain advanced technologies through digital transformation for shipbuilding & offshore plants, one of Korea's representative manufacturing industries. Therefore, the digital transformation of the shipbuilding & offshore plant industry was defined using an input-output analysis model, and the economic interrelationships of industries linked to the digital transformation of the shipbuilding & offshore plant industry were analyzed. According to the analysis, the shipbuilding & offshore plant industry ranks second among all 34 industries regarding the forward linkage effect. The backward linkage effect was ranked 27th, making it a mid-demand industry with a robust forward linkage effect. In addition, the production-induced effect was 0.455, the value-added-induced effect was 0.174, and the employment-induced effect was 1.779 people per billion won. The contribution of this study is that it will provide the basis for establishing policies necessary to strengthen the competitiveness of the shipbuilding & offshore plant industry. Also, it will help analyze the economic effects of digital transformation in other manufacturing industries.

본 논문은 세계산업연관표의 전후방연쇄효과를 이용하여 2000년부터 2014년까지의 한국, 중국, 일본의 1차 산업의 생산유발효과를 비교 분석하였다. 1차 산업의 산업영향력에 관한 연구는 활발히 진행되어 왔으나, 본 논문은 1차 산업 분야에 대한 한국, 중국, 일본의 산업연쇄효과의 차이에 대한 연구라는 점에서 의미가 있다. Fisher(1939)와 Clark(1957)의 1차 산업 분류에 따라 1차 산업을 농림축산업, 임업, 수산업, 광업으로 분류하였다. 분석방법으로는 세계산업연관표를 이용하여 한국, 중국, 일본 3국간 산업연관모형을 만든 후 비교분석하는 것이다. 본 연구의 결과에 따르면, 농림축산업, 광업은 한국, 중국, 일본 각 국가별로 전 후방 연쇄효과에 유의한 차이가 있었고 임업과 수산업의 경우 한국, 중국, 일본의 전 후방 연쇄효과에 부분적으로 유의한 차이가 있었다. 1차 산업의 산업의존도 변화를 4차 산업혁명의 시대에 산업의 전방연쇄효과와 후방연쇄효과를 IO 분석을 통해 각 국가별로 비교함으로서 향후 1차 산업이 나아가야할 방향을 제시하였다.

Objectives: This study aimed to establish a linkage model involving regional responsible medical institutions after analyzing the existing conditions and deriving problems through qualitative analysis within the community care system. Methods: A total of 14 participants of this study were selected through the snowball sampling method, including 7 community care service providers and 7 service users. As for the research data, primary data were collected through interviews, and as a result of analyzing according to Aday&Anderson' model, a total of 5 catergories, 8 topics, and 22 sub theme were derived. Results: The problem derived from the interview is that division services are provided for each institution due to the absence of a key central institution of community care system, and users' commercial institutions is unclear. The second is the inconsistency between the needs and supply for community care, resulting in a possibility of delay in returning to the community after discharge. Based on these problems, it is necessary to unify it as an community care window of the Dong-community center. In addition, there is a need for public health centers to play an active role, and to establish a public-private joint system with the Health and Living Support Center to establish a model that can play a certain role. Conclusions: Therefore, based on the results of this study, it can be used as basic data when constructing community care model and applying it as an expanded model in the future.

This paper is an exploratory study to analyze the flow of knowledge in science and technology in order to predict technology innovation. Here, we need to look into the characteristics of how knowledge is created in science, technology and industry to start with. Based on the characteristics we find, we have to understand the relationships between science, technology and industry, and construct a model to link them to each other for future empirical studies. In this study, we take a general view of the existing study results and theoretical models on the characteristics and linkage of scientific and technological knowledge. Moreover, we examine the preliminary framework to link science to technology to industry for further study on the knowledge flow of science and technology. Finally, we present the direction for future study by using the examined models and framework.

An adaptive current control scheme of a permanent magnet (PM) synchronous motor with the simultaneous estimation of the magnitude of the flux linkage and stator resistance is proposed. The adaptive parameter estimation is achieved by a model reference adaptive system (MRAS) technique. The adaptive laws are derived by the Popov's hyperstability theory and the positivity concept. The predictive control scheme is employed for the current controller with the estimated parameters. The robustness of the proposed current control scheme is compared with the conventional one through the computer simulations.

This paper aims to examine the main factors of the job embeddedness on organizational citizenship behavior and job performance. To accomplish these purposes, the main factors of the job embeddedness such as fit, linkage, and sacrifice were found from the previous studies. The questionaries of 250 were distributed to the employees working at the Gumi Industrial Complex. The questionaries of 220 were obtained and 204 were analyzed through frequencies, correlation and multiple regression. The results of this study are as follows; First, we conducted exploratory factor analysis for three constructs (fit, linkage, and sacrifice) using oblique rotation method that did not assume independence among the factors and main factors of job embeddedness were grouped together by three factors. Second, it is shown that three main factors of job embeddedness have a positive influence on the organizational citizenship behavior and job performance (p<0.05). This study, however, have limitations of number of sample and survey area. The future study should consider these limitations in improving model applicability in practice.
