본 연구는 상추 '피델'을 이용한 완전제어형 식물공장에서의 재배를 하기 위해 기존의 배양액에 생육 촉진용 AMG의 농도를 구명하고 그에 맞는 매뉴얼을 확립하기 위해 실시하였다. 실험은 기존 배양액에 AMG(고활성 칼슘용액+복합 활성 미네랄)를 추가하였으며 '피델'의 생육에 적합한 AMG의 농도는 0, 0.05, 0.1, 0.2%를 양액에 추가하여 5반복 4처리로 진행하였다. 생육 조사 항목은 초폭, 초장, 엽장, 엽폭, 엽록소, 생체중을 조사하였다. '피델'의 생장에서 초폭, 엽폭, 엽장은 3주차부터 생장량이 급증하였으며 AMG 4처리구 5주차 조사에서는 초폭 평균 335g, 357g, 369g, 381g을 나타냈으며 엽폭은 평균 168g, 191g, 202g, 208g, 엽장 평균 129g, 134g, 144g, 144g으로 조사되었다. AMG 농도 0.1~0.2%는 통계적으로 생장 촉진 효과가 나타났으나 유의차가 크지 않아 0.1% AMG가 적정한 것으로 판단되었다. 엽록소함량의 경우 정식 2주차 이후서부터는 SPAD 평균 29~32로 기록되어 엽록소함량은 크게 변화하지 않았다. 또한 엽수의 증가폭에 비해 생체중의 증가폭이 컸으며 생체중의 경우 정식 3주부터 5주 사이에 생체중이 5배 이상 급증하는 생장 패턴을 나타내었다. 5주차 생체중에서는 0% AMG의 경우 평균 82g, 0.05% AMG는 평균 85g, 0.1% AMG는 평균 115g, 그리고 0.2% AMG는 평균 114g으로 조사되었다. 따라서 0.1~0.2% AMG에서는 차이가 없게 나타남에 따라 생장촉진을 위해서는 0.1% AMG를 추가하는 것이 적정하다고 판단되었다.

The global intelligent transport systems (ITS) market is experiencing rapid growth, and domestic ITS companies' efforts to extend its business abroad are steadily increasing. However, due to the burden of costs associated with the overseas expansion and the lack of strategy for local market, domestic companies' contracts for global businesses are far short of the technology. Although the government is actively promoting Korean enterprises' participation to overseas business, it has obvious limits due to the lack of its specialized strategy. This study established a customized export model for the countries in which Korean companies want to enter, and developed a strategy to advance into the local market.

Little empirical study has been conducted concerning board function effectiveness and organizational performance in nonprofit nongovernmental human service organizations in Korea. Using the evaluations of 107 board members and 17 executive directors in Korean Community Chest and 16 regional community chests, this study attempted to examine the level of board function effectiveness and its relationship with organizational performance in these community chests. This study used board function scale developed by Holland and Jackson (1998) to measure board function effectiveness in the following 6 dimensions: contextual dimension: educational dimension: interpersonal dimension: analytical dimension: political dimension: and strategic dimension. This study showed that using 4 points scale, mean of overall board function effectiveness evaluated by board members is 2.62 and mean of overall board function effectiveness evaluated by executive directors is 2.73. That is, it showed that means of overall board function effectiveness are located in the middle point between negative evaluation and positive evaluation. On the other hand, using parametric correlation analysis method, it was found that in these community chests the association between board function effectiveness and organizational performance measured by fund-raising growth rate in $1999{\sim}2000\;and\;1998{\sim}2000$ is very weak and statistically nonsignificant. This study also revealed that using nonparametric correlation analysis method, the association between consensus level in evaluation by board members and executive directors about board function effectiveness, and organizational performance is still very weak and statistically nonsignificant. Finally, this study discussed the direction of future research in board function effectiveness and its relationship with organizational performance and the areas of board management that requires substantial efforts for promoting effectiveness of nonprofit human service organizations in Korea.

The purpose of this study was to evaluate the healing process of the calvarial defect filled with hydroxylapatite(HA) and $TGF-{\beta}$ in Rat. 72 Sprague-Dawly rats were divided into 3 groups, control and two experimental groups. Bony defect were artificially prepared in the calvaria of all 72 rats and followed by implantation of HA (experimental group of 24 rats) and HA+$TGF-{\beta}$(another experimental group of 24 rats) into the defects. Sequential sacrifice was performed at 1, 2, 4, 6, 8, 12 weeks of experiment. Obtained specimen was stained with Hematoxylin and Eosin, Masson's Trichrome and Immunohistochemistry. The results were as follows, 1. Granulation tissue was prominent on control group in 1 and 2 weeks. Bony defects were filled with dense fibrous tissue through the whole experimental period and osteoinduction could not be observed in all groups. 2. Inflammatory cell infiltration was prominent on control group in 1 and 2 weeks and osteoclastic activity was high in HA implanted experimental group at 1 and 2 weeks. 3. Inflammatory cell infiltration was less and maturation of fibrous tissue could be found on HA+$TGF-{\beta}$ implanted experimental group at 1 and 2 weeks. 4. Osteoconduction activity was high in HA+$TGF-{\beta}$ implanted experimental group at 2 and 4 weeks but there was no difference after 6 weeks among 3 groups. 5. In grafted site of HA+$TGF-{\beta}$ implanted group, osteonectin expression was slightly increased from 1 week to 6 weeks. In the host site, it was increased from 1 to 4weeks. 6. In grafted site of HA+$TGF-{\beta}$ implanted group, osteocalcin expression was high at 4 weeks. In the host site, we could find the difference among 3 groups. From above results, the HA with mixture of $TGF-{\beta}$ has the potentiality of promoting bone formation in the bony defect area in the rat.

Korean Government is implementing green remodeling projects on existing buildings and structures in a way of promoting low carbon green growth. However, the current regulations and systems do not clearly define the scopes and contents of the green remodeling. Also, the lack of the inducement measure is another reason of the low engagement of the private enterprises to the green remodeling business. Therefore, this study proposes a tax exemption plan to promote green remodeling business implementation, with the consideration on practical applicability. And the proposed plan was applied to the green remodeling pilot project case in2 014 and the effect was quantitatively analyzed. The result is expected to be used as a base data to improve the tax exemption benefit system to invigorate green remodeling later.

Historically, college campuses have played a role of a city, and the development pattern of various forms and functions of cities was found in the growth stages of campuses as well. In this way, campuses developed in close relationships with our lives and such a characteristic can be confirmed in a number of cases in and out of the country. The strategic concept of such expansion is shown in the strategic classification through a master plan. This research examines concepts of major universities in the metropolitan area of Korea for promoting campus expansion and proposes implications through them. The results drawn from the research are as follows. Firstly, various developmental directions should be sought in aspects of planning, programming and economics for campus expansion with the complex application of such factors. Secondly, the multi-campus strategy of past localization era is changing into the concept of forming a global campus materializing itself as the planning strategy of internal campus. Thirdly, the physical barrier is being dissolved as a way to promote the relationship with local communities, and particularly, the management strategy of constructing new buildings in connection with local communities is the leading measure of materialization. Lastly, the development of underground space is actively carried out due to the limitation of ground physical space through which a role of establishing new campus order along with securing space is pursued.

In digital age export expansion is the key fact of promoting Korea's economic growth. The policy that encourages exportation is being more emphasized to develop of the nation's economy. From the 90's, regionalism has been widespread throughout the world with globalization and internationalization led by WTO and FTA. The world is now becoming one economic bloc. It is necessary to understand how enterprises contribute to the exportation to establish and manage the policy that encourage and support the exportation. This study estimates SME's level of contribution on gross exports and understands the problem, while looking for better statistical alternatives and finding SME's export energizing policies. It is estimated that domestic SMEs contribute about 40-50% of gross exports. SME bureau and national statistical office should select optimal size of population of each industry, design and extract sample to conduct the export related survey extensively. SMEs should analyze the product and skills of the industry that is dominated by major companies to contribute to the exportation more efficiently. This effort will increase the level of contribution to gross exports in general.

The integration of products and services is being expanded in both manufacturing and service companies such as in Apple's iPod & iTunes, Amazon's Kindle, and Hyundai Motor Company's Mozen. This phenomenon has recently accelerated due to multiple factors including market change, lessening of differences in quality of products or services, the paradigm of participation and sharing, and deindustrialization and evolution toward becoming a service economy. The objective of this paper is to investigate and analyze the status and characteristics of integration of products and services in Korean firms and to suggest policy directions promoting this integration. Towards this purpose, income statements from the Korea Listed Companies Association (KLCA) database of companies listed on the Korea Stock Exchange are analyzed regarding the servitization of manufacturing firms as well as the productization of service firms. In addition, this research investigates the Korean Innovation Survey 2011 database for the service sector and 2010 database for the manufacturing sector in order to evaluate R&D activity in each. In the manufacturing sector, the average ratio of service sales (servitization) was low at 0.208, with bias in the level and distribution of ratios associated with the manufacturing sector. 18 out of a total of 23 sectors (78%) have low servitization, showing there's a long way to go for servitization in the Korean manufacturing sector. In the service sector, the average ratio of product sales (productization) was 9.53%, which is relatively high compared to that of the manufacturing sector. However, the distribution of ratios is also biased, as with the manufacturing sector. Based on this analysis, policy directions are proposed in terms of 1) R&D, 2) concept boost, 3) R&D result spread, 4) statistics, 5) infrastructure and 6) green growth.
