Waste to Energy Plant were recognized as hateful facilities, and there were many conflicts in the location due to social problems such as the NIMBY phenomenon due to problems such as damage to property in the surrounding area, odor, and image loss. Problems such as air pollution and odor are solved by the development of advanced prevention facilities such as electric dust collectors, wet cleaning systems, semi-dry reaction towers, bag filters, and catalyst towers (SCR: Selective Catalytic Reduction), and air recycling facilities in waste storage tanks. However, it is being avoided because of the perception that it is an incinerator. To resolve these conflicts, the government installs and operates resident convenience facilities to compensate residents near resource recovery facilities, provides green space and improves the environment, and supports heating expenses in accordance with the 「Waste Treatment Facility Support Act」. The purpose of this study is to derive implications through the analysis of domestic and overseas case studies for resident convenience facilities and environment improvement for the promotion of local communities in resource recovery facilities and use them as basic data for community promotion and environmental improvement when installing resource recovery facilities in the future.

A Study on the Fine Structure of the Marine Diatoms of Korean Coastal Waters - Genus Thalassiosira 4

정승원,Seung Won Jung,Jin Hwan Lee 한국조류학회I 2009 ALGAE Vol.24 No.2

The marine phytoplankton diatom Thalassiosira species are described from the Korean coastal waters, based on observations of fine structure of its frustules. As a fourth series, this study deals with 5 Thalassiosira species (T. decipiens, T. eccentrica, T. mala, T. nodulolineata, and T. proschkinae). The most striking features of these species are also the form and position of two processes on frustules. There is a central strutted process on valve face except T. nodulolineata, which has a modified one on its center. The external tubes of marginal strutted processes are divided two forms: “pile” form in T. decipiens and T. proschkinae, “short straw” form in T. eccentrica and T. nodulolineata. T. mala does not present the external tubes in valve margin. The labiate processes are located in valve margin except T. proschkinae, which has it on valve face. Of these, three species (T. mala, T. nodulolineata at a final contentration of 5% and T. proschkinae) were newly recorded in the coastal waters of Korea.

In order to understand variation and relationship between standing crops and biomass of phytoplankton dominant species for the long term periods, this study was seasonally investigated in the marine ranching ground of Tongyeong coastal waters from 2000 to 2007. Total 268 taxa representing 217 Bacillariophyceae, 46 Dinophyceae, 4 Dictychophyceae, 1 Euglenophyceae were observed in phytoplankton communities. Dominant species consisted of 5 species as standard in standing crops: Chaetoceros curvisetus (18.01%), Chaetoceros socialis (12.95%), Skeletonema costatum (8.39%), Chaetoceros compressus (6.87%), Asterionellopsis glacialis (5.02%). However, to determine dominant species as biomass concept, Ditylum brightwellii, Guinardia striata, Rhizosolenia spp. and Skeletonema costatum were occupied with dominant species (19.67%). As determining for cell sizes, dominant species were divided with two groups such as micro- and nanophytoplankton (standing crops) and mesophytoplankton (biomass). However, Skeletonema costatum in anophytoplankton was associated to affect fluctuation between standing crops and biomass.

정승원,김소미,변성수,박형식,정영수,Chung, Seung-Won,Kim, So-Mi,Byun, Sung-Soo,Park, Hyung-Sik,Jung, Young-Soo 대한악안면성형재건외과학회 2011 Maxillofacial Plastic Reconstructive Surgery Vol.33 No.4

Purpose: McNamara and Delaire analyses are two commonly used analytic methods, yet, they differ in their theoretic concepts and different reference lines are used for ideal surgical prediction. Therefore, the use of different analytic methods may result in different surgical plans. The purpose of this study was to compare the anterior and posterior relationship of the maxilla and mandible by using McNamara and Delaire analysis. Methods: 30 Korean patients (15 male and 15 female) who had visited the Department of Oral and Maxillofacial Surgery, College of Dentistry, Yonsei University, for dentofacial evaluation were studied by using McNamara's and Delaire's analyses. Results: On the maxillary analysis, 26 out of 30 patients (86.7%) were in accordance. On the mandibular analysis, 20 out of 30 patients (66.7%) were in accordance. On the maxillary analysis, McNamara's analysis showed an average of 0.36 mm greater amount of prognathism compared to Delaire's analysis, and this was not statistically significant. On the mandibular analysis, McNamara's analysis showed an average of 6.03 mm greater amount of prognathism compared to Delaire's analysis, and this was statistically significant. On the mandibular analysis, 26 out of 30 patients (86.7%) showed a greater amount of prognathism on McNamara's analysis compared to that of Delaire's analysis. The remaining 4 patients (13.3%) showed the same amount of prognathism on both analyses. Conclusion: These results may serve as a reference for surgeons when determining which analytic method is to be used for optimal surgical results.

Embedded capacitor technology can improve electrical perfomance and reduce assembly cost compared with traditional discrete capacitor technology. To improve the capacitance density of the $Al_2O_3$ based embedded capacitor on Cu cladded fiber reinforced plastics (FR-4), the specific surface area of the $Al_2O_3$ thin films was enlarged and their surface morphologies were controlled by anodization process parameters. From I-V characteristics, it was found that breakdown voltage and leakage current were 23 V and $1{\times}10^{-6}A/cm^2$ at 3.3 V, respectively. We have also measured C-V characteristics of $Pt/Al_2O_3/Al/Ti$ structure on CU/FR4. The capacitance density was $300nF/cm^2$ and the dielectric loss was 0.04. This nano-porous $Al_2O_3$ is a good material candidate for the embedded capacitor application for electronic products.

Changes in physical, chemical and microbiological characteristics of rice-doenjang prepared with two different methods with or without soak treatment were investigated during 60 days of aging at 32℃ and 15℃. The pH of soak-treated rice-doestjang decreased slowly, but that of nonsoak-treated rice-doenjang decreased rapidly at the initial aging stage with the aging temperature of 32℃, resulting in pH 5.1 after the 60 days of aging time. Reducing sugar contents increased up to the 30∼50 days of aging time and decreased thereafter. The contents of soluble nitrogen, formol nitrogen, ammoniacal nitrogen and amino nitrogen were more affected by preparation methods than by aging temperatures. Color values depended not only on preparation methods but also on aging temperatures. There were no significant differences in the bacterial counts of rice-doenjang, while apparent differences in the yeast and mold counts by aging temperatures were observed. These results suggested that the properties of soak-treated rice-doenjang were less changed than those of nonsoak-treated rice-doenjang by aging time and temperature. Md, with a view point of nitrogen compounds, aging time could be reduced by soak treatment.

요한 칼빈의 일반계시 개념과 그 변증학적 의의

정승원(Jung, Sung-Won) 개혁신학회 2009 개혁논총 Vol.12 No.-

In Christian theology, even in Reformed tradition, the general revelation has been neglected in its theological and apologetical significance, compared to the special revelation, that is, the Scriptures. The reason for this might be that the general revelation is conceived to be not at work for the salvation. However, the Calvinistic heritage is far from being the biblicism which idolizes the Bible by neglecting the significance of the general revelation. It is true that the general revelation is ineffective in salvation of men, yet it doesn't mean that it turns out to be useless in knowing God. Although the natural theology is inadequate, the general revelation is still adequate in knowing God in the sense that no one is able to escape from His revelation clearly shown in the nature, His providence and in human made in His image. Even the fall doesn't invalidate the revelatory nature of the general revelation. It is still God's revelation, which is supposed to stand forever, in spite of the fall. What the fall ruined is not God's revelation in nature and in man, but the nature and man. In this paper I attempted to show that John Calvin renders the great significance to the general revelation. Specially in his Institutes Calvin emphasizes two knowledges that everyone is supposed to have; the knowledge of God and the knowledge of man. He also emphasizes the inescapableness of the general revelation shown in the nature and human mind. But he doesn't forget to emphasize that the sin blinds the sinners, it distorts the knowability of the general revelation, and it makes them deliberately deny the knowledge of the Creator attained by virtue of the revelation. The knowledge by which Calvin means is not an intellectual ability or a speculation, rather a living experience in relationship with God. The knowledge is revelatory in character. That is why Calvin emphasizes the inescapableness of the knowledge of God of men and the ignorance of the non-believers about God at the same time. Thus Calvin's emphasis on the inescapableness of the general revelation has an apologetical significance. A rational proof or experiential evidence is not enough to defend the truth of Christianity because unbelievers are rational enough to deny any proof or evidence. But they can't deny the revelatory knowledge implanted in their minds. Nor can they deny the foundation in which they live, think, and act. They have to rely on the foundation in even denying its existence. Consequently, Calvin's understanding of the general revelation is very effective in defending the Christianity.

선탑재 애플리케이션은 스마트폰 출고 시 사용자에게 최소한의 기능을 제공할 수 있도록 출고와 동시에 설치된 애플리케이션으로 삭제가 어렵기 때문에 타 애플리케이션에 비해 사용자와 관련된 증거 데이터가 존재할 가능성이 높다. 위치정보는 선탑재 애플리케이션이 저장하는 데이터 중 디지털포렌식 관점에서 의미 있는 데이터로써, 시간정보와 결합하여 사용자의 이동 경로와 목적지 등을 유추할 수 있기 때문에 정황증거 확보 및 현장부재 증명을 수행할 수 있는 중요한 단서로써 활용 가능하다. 따라서 본 논문에서는 국내에서 점유율이 높은 스마트폰의 선탑재 애플리케이션을 대상으로 디지털포렌식 수사에서 사건 발생 시 즉각 활용될 수 있는 위치정보를 분석한다. 또한 시간정보를 활용한 이동 경로 추적 방안에 대해 제시하고 경로를 추적할 수 있는 자동화 도구 개발 결과를 다룬다. 본 논문에서 수행한 삼성 기종 스마트폰 6종을 대상으로 선탑재 애플리케이션 50여개, 엘지 기종 스마트폰 V30를 대상으로 선탑재 애플리케이션 20여개를 분석한 결과 5개의 애플리케이션에서 위치정보 수집이 가능했으며, 이를 기반으로 개발된 자동화 도구는 사용자 이동 경로 추적이 가능함을 보였다. Pre-installed applications are designed to provide minimal function and installed when the mobile devices is shipped, and they can be used as evidence due to difficulty in deleting them. Location information is forensically meaningful data among data stored by pre-installed application. It can be important clue to secure contextual evidence and to get an alibi since it can infer user’s route and destination in combination with time information. Therefore, in this paper, we analyze location information of pre-installed applications on mobile devices with high market share in Korea so digital investigation can be processed immediately when an incident occurs. In addition, this paper presents a route tracking method using time information and introduces an automated tool that can track the route. As a result of analyzing the 50 pre-installed applications for Samsung mobile devices and 20 pre-installed applications for LG V30, we were able to collect location information from 5 pre-installed applications. Based on this, Our automation tools have shown that it is possible to track the route.
