The unification mission of the Korean church is carried out with more Diakonia than Kerygma. It has the positive effects on the national product as well as on the food-and nutrition status in North Korea, besides on the personal relations between South and North Korea. It has also the positive mission effect in North Korea, although that is not confirmed exactly with number. But because of the exclusionism of the North Korean regime transparency and efficiency of the aid become hot issues and induced the ‘South-South conflict’. Not only that, the humanitarian aid is under the strong influence of the political situation. Moreover in the year 2010 because of the attacking Chunan-Ham and the bombardment Yunpyung-Do the diaconal activity of the Korean church must be closed. In order to exceed these limitations an another diaconal method can be proposed. That ist the commercial aid with return beside the contributive aid without return. The commercial aid with return has not few advantage: ⑴ It ist a international business, that is political neutral furthermore protected by government. ⑵ The commercial aid produces value-added, that can be the self-supporting ground for the partner. ⑶ Therefore the commercial aid does not induce the partner to fall in the ‘Samaritan’s dilemma’. ⑷ The commercial aid is self-sustaining and can be enlarged, if it makes a profit. ⑸ The material resource of aid is invested in business and in production system, not concentrated on a place. ⑹ The commercial aid does not make ‘agent problem’, nor the problem of low transparency and low efficiency on the level of the contributive aid. But what ist more important, is the harmony of Korean churches to make a unified organization, that takes care of the commercial aid. This organization can concentrate the unification power of the Korean churches, because it could treat the problem of the internal competition between Korean churches themselves, the overlapping of aids, the monitoring etc. In the end the harmony of Korean churches determines the time of the Unification in the korean peninsula.

We developed an efficient Monte-Carlo algorithm to solve dust-scattering radiative transfer problems for continuum radiation. The method calculates the scattered intensities for various anisotropic factors ( gi) all at once, while actual photon packets are tracked following a scattering phase function given by a single anisotropic factor ( g0). The algorithm was tested by applying the method to a dust cloud embedding a star at the cloud center and found to provide accurate results within the statistical fluctuation that is intrinsic in Monte-Carlo simulations. It was found that adopting g0 = 0.4 - 0.5 in the algorithm is most efficient. The method would be efficient in estimating the anisotropic factor of the interstellar dust by comparing the observed data with radiative transfer models.

Since it has been reported that asbestos fibers cause serious health problems such as lung cancer, malignant mesothelioma and other related diseases, it turns into social issue leading to a number of studies for characterizing asbestos found in the indoor environment. Among the established methods for detecting asbestos fibers, phase contrast microscopy (PCM) method is widely used as it dose not require complicated process nor high-priced equipments. However, PCM method is hard to define a sort of asbestos and to detect tiny asbestos fibers. We developed an image-based high-throughput microscopy (HTM) for automated counting of asbestos fibers which were distinguishable from the spherical particles. HTM method enabled us to analyze asbestos fibers both automatically and quantitatively. Test samples of chrysotile, amosite and crocidolite, which are frequently detected in Korea, were used in this study and comparisons were made between concentrations of asbestos fibers measured by manual counting method and HTM method. Application of HTM system can be extended to various areas such as malaria diagnosis, rare cell detection and bacterial colony counting.

Today, many companies have introduced an ERP system - an enterprise resources planning - in order to improve corporate credibility through transparent management and for quick responses to market situations through quick decision making. After the construction of an ERP system, many companies are having difficulty in calculating the appropriate number of personnel required for running the system because of a lack of standard for doing so, as well as a lack of pertinent procedures. As a result, the companies are having to resort to a trial-and-error approach. Therefore this paper studied a model for calculating the appropriate number of personnel required for efficiently running an ERP system after its construction, as well as for constantly meeting its performance targets. The developed model was applied empirically to calculate an appropriate number of personnel required, and an organization was set up according to this. Therefore, the purpose of this study was to present an optimized model for calculating the number of personnel required for operating an ERP system, that which addresses problems of existing models, in order to help companies organize the operation personnel and its size, as well as to provide more objectivity to the calculated number of personnel required and to improve credibility.

This paper describes the results of the application of Cr-Diamond-like carbon (DLC) films for efficiency improvement through surface modification of spur gear parts in the hydraulic gear pump. Cr-DLC films were successfully deposited on SCM 415 substrates by a hybrid coating process using linear ion source (LIS) and magnetron sputtering method. The characteristics of the films were systematically investigated using FE-SEM, nano-indentation, sliding tester and AFM instrument. The microstructure of Cr-DLC films turned into the dense and fine grains with relatively preferred orientation. The thickness formed in our Cr buffer layer and DLC coating layer were obtained the 487 nm and . The average friction coefficient of Cr-DLC films considerably decreased to 0.15 for 0.50 of uncoated SCM415 material. The hardness and surface roughness of Cr-DLC films were measured 20 GPa and 10.76 nm, respectively. And then, efficiency tests were performed on the hydraulic gear pump to investigate the efficiency performance of the Cr-DLC coated spur gear. The experimental results show that the volumetric and mechanical efficiency of hydraulic gear pump using the Cr-DLC spur gear were improved up to 2~5% and better efficiency improvement could be attributed to its excellent microstructure, higher hardness, and lower friction coefficient. This conclusion proves the feasibility in the efficiency improvement of hydraulic gear pump for industrial applications.

The hybrid structured photo-electrode for dye-sensitized solar cells was fabricated based on the composites of nanoparticles and nanowires. Three samples with different hybrid structures were prepared with 17 vol%, 43 vol%, and 100 vol% nanowires. The energy conversion efficiency was enhanced from 5.54% for pure nanoparticle cells to 6.01% for the hybrid structure with 17 vol% nanowires. For the hybrid structured layers with high nanowires concentration (43 vol% and 100 vol%), the efficiency decreased with the nanowire concentration, because of the decrease of specific surface area, and of thus decreased current density. The random orientations of nanowires can be preserved by the doctor blade process, resulted in the enhanced efficiency. The hybrid structured layer can possess the advantages of the high surface area of nanoparticles and the rapid electron transport rate and the light scattering effect of nanowires.

본 연구에서는 흑미의 가공부산물인 흑미강으로부터 기능성 polyphenol 및 flavonoid가 새로운 추출방법인 아임계 추출법을 통해 추출되었고, 열수(80oC), 에탄올, 설탕용액을 이용한 기존 추출법과의 추출효율이 비교 분석되었다. 건조된 흑미강 시료로부터 polyphenols(35.06±1.28 mg QE/g dried material) 및 flavonoids(7.08±0.31 mg QE/g dried material)에 대한 최대 수율이 아임계 추출법(190oC, 1300 psi, 10 min)을 통해 획득되었으며, 이것은 기존 추출법 가운데 가장 높은 수율을 보인 에탄올 추출법을 통한 polyphenols(2.98±0.74mg QE/g dried material) 및 flavonoids(0.58±0.21mg QE/g dried material) 수율 대비 11.77배와 12.21배 이상 더 높은 것이었다. 추출방법에 따른 흑미강 추출물의 항산화 활성은 에탄올 추출물에서 가장 높게 관찰되었다. 그러나 흑미강 시료 1 g 당 획득된 추출물의 건조중량 차이 비교를 통해서 얻어진 건조 흑미강 1 g 당 함유된 항산화 성분의 상대수율(relative yield, %)은 최적조건(190oC, 1,300 psi, 10 min)의 아임계 추출법을 통해 획득된 추출물에서 가장 높았으며, 이것은 에탄올 추출물의 항산화 성분 상대수율에 비해 대략 11.53배 이상 더 높은 것이다. 이상의 결과들은 아임계 추출법이 흑미강으로부터 기능성 polyphenols 및 flavonoids를 추출하는데 매우 적합한 방법임을 설명하고 있으며, 유기용매 추출법을 포함한 기존의 전통적 추출법에 대한 매우 효과적인 대안임을 제시하고 있다.
