In this study, we have coated the inner surface of YSZ channel using LSM powder ink through depressurization process for making the cathode of a stacked planar-type SOFC module. To coat the surface of YSZ channel uniformly, we tried to find the optimum manufacturing condition for LSM ink. We used four different dispersants (BYK series) and two different solvents (ethanol and DMF) to make the LSM ink. It was revealed that the ink made with the ethanol solvent and the BYK-111 dispersant has the lowest viscosity, relatively low contact angle and most excellent dispersibility. After depressurizing a chamber filled with LSM ink and sintered YSZ channel, we have found that the YSZ channel was uniformly coated with LSM cathode. The LSM ink with 25 vol% BYK-111 showed the most uniform coating.

이성일,함은구,Lee, Sung-Il,Ham, Eun-Gu 한국재난정보학회 2021 한국재난정보학회 논문집 Vol.17 No.2

연구목적: 교육시설 화재위험성 평가를 위한 기초 데이터 확보를 위하여 화재하중 분석하였다. 사전조사로 화재하중을 산정하기 위해 학교시설의 화재하중과 관련된 기초자료를 수집하였다. 연구방법: 기초자료는 화재하중의 정의 및 종류, 화재하중 산정을 위한 연소열 데이터 화재하중에 대한 선행연구를 통하여 진행하였고 화재하중 산출시 구획실에 존재하는 가연물 중량에 해당 연소열을 곱하여 산정하였다. 연구결과: A 초등학교의 고정가연물은 교실, 음악실, 교무실은 정서나 안전을 고려하여 바닥이 주로 목재로 이루어져 있었으며, 나머지 구획실은 석재로 이루어졌다. 천장과 벽은 석고보드, 콘크리트로 되어있어 가연물에 속하지 않았다. 각 실별로 대표적인 적재가연물은 교실은 책상, 의자, 사물함 등으로 나타났으며 과학실은 실험기구함, 실험도구함이 주를 이루어었으며 도서실은 책과 서가, 열람기구 등이 큰 비중을 차지하였다. 결론: A 초등학교의 적재가연물에 따른 적재화재하중은 도서실, 컴퓨터실, 영어학습실, 교무실, 일반교실, 과학관, 음악실의 순으로 나타났다. Purpose: Fire load analysis was conducted to secure basic data for evaluating fire risk of educational facilities. In order to calculate the fire load through a preliminary survey, basic data related to the fire load of school facilities were collected. Method: The basic data were the definition and types of fire loads, combustion heat data for the calculation of fire loads. The fire load was evaluated by multiplying the combustion heat by the weight of the combustibles in the compartment when calculating the fire load. Result: As for the fixed combustible materials of A-elementary school, the floor was mainly made of wood, in consideration of emotion and safety in the classroom, music room, and school office, and the rest of the compartments were made of stone. The ceiling and walls were made of gypsum board and concrete, so they were not combustible. The typical inflammable items in each room were desks, chairs, and lockers in the classroom, and the laboratory equipment box and experimental tool box were the main components in the science room, and books, bookshelves, and reading equipment occupied a large proportion in the library room. Conclusion: 'The fire loads of A-elementary' schools according to the combustibles loaded were in the order of library, computer room, English learning room, teacher's office, general classroom, science hall, and music room.

The Salmonella rfb gene encoding for the biosynthesis of the oligosaccharide-repeating units of the O-antigenic determinants was cloned and sequenced. A set of nucleotide primers(a forward and reverse) was selected to target a defined region of the guanosine diphospho-mannose(GDP-Man) pyrophosphorylase synthase gene : rfbM of Salmonella C serogroup. The primer set was used to develop a PCR-based rapid and specific detection system for Salmonella C1 serogroup. Amplification bands of predicted size(1,422bp) were generated from 11 different Salmonella C1 isolates. The bands were verified to be specific for the C1 serogroup by Southern blot analysis using reference homologous DNA specificity was further confirmed by the lack of reactivity with heterologous DNA derived from non-salmonella members of the family enterobacteriaeceae. A specificity of 100% was deduced along with a very high sensitivity shown by a detection limit of 1fg of a purified DNA template. The isolated DNA sequence was found to be 99.8% homologous to S montevideo but the related primers amplified with the predicted band sizes with all the Salmonella C1 serogroups tested. It is concluded that the PCR protocol based on the rfbM gene from S cholerasuis is optimal fast and specific for the detection of Salmonella C1 serogroup and also the corresponding probe is suitable for rapid detection of all Salmonella C1 serogroup DNA tested. This technology should facilitate the identification of contaminated pig products and for any other products contaminated with the Salmonalla C1 serogroup. The immediate impact of this developed method will be in the area of food safety of pig products with the potential prospect for adaptation to other food inspection technologies.

건설 현장 강행공사 방지가 인적사고에 미치는 영향에 관한 연구

In the construction sites, rush (speedy construction) work have recently been overused because of budget reductions by reducing the construction duration after the long-term economic recession and construction business stagnation with institutional change including the instruction of the duration shortening bidding system and the introduction of the post-construction sales system by the Korea Research Institute for Human Settlements. Due to this, negligent accidents have frequently occurred by forcing manpower, equipment, finance, and material procurement and pressing ahead with impractical construction wok at night according to the reduction of construction schedules. Therefore, this paper has the necessity of this study to seek for alternatives to prevent negligent accidents by finding factors related to rush work in the reality that the importance for preventing negligent accidents is more emphasized while they have not been reduced in construction sites.

A case of facial reconstruction with muscular flaps of the platysma and sternocleidomastoid muscles in patient of the 1st and 2nd branchial arch syndrome was presented. Surgery was performed through preauricular, submandibular and supraclavicular incision to detach both muscles and transrotate up to recessed region of the face. Unilateral facial underdeverlopment, namely branchial arch syndrome, which is well known as one of the congenital malformations commonly arising etiologically from disturbance of normal growth on the 1st and 2nd branchial arch formation and development during prenatal phase was reconstructed with platysma muscular flap on left cheek area and sternocleidomastoid muscularflap on left mandibular angle area. By follow-up check of the patient for 4 months after operation, we obtained good results functionally and esthetically.

Chemical mechanical polishing (CMP) technology has been widely used for global planarization of multi-level interconnection for ULSI applications. However, the cost of ownership and cost of consumables are relatively high because of expensive slurry. In this paper, we studied the mixed abrasive slurry(MAS). In order to save the costs of slurry, the original silica slurry was diluted by de-ionized water (DIW). And then, ZrO₂,CeO₂, and MnO₂ abrasives were added in the diluted slurry in order to promote the mechanical force of diluted slurry. We have also investigate the possibility of mixed abrasive slurry for the oxide CMP application.

조세포탈죄와 체납처분면탈죄의 법정형의 적정성 여부

이성일(Sung Il Lee) 대검찰청 2022 형사법의 신동향 Vol.- No.75

2010년 조세범처벌법이 전면 개정되면서 종전과 달리 조세포탈죄의 기본적 구성요건에 관한 법정형이 체납처분면탈죄보다 더 낮게 역전되었다. 그런데 조세포탈죄의 보호법익인 조세부과권은 체납처분면탈죄의 보호법익인 조세징수권보다 더 우월하고, 조세부과권을 형해화시킬 정도로 조세징수권이 저해된 경우에 비로소 조세포탈죄가성립한다는 점에서 죄질이 조세포탈죄가 더 나쁘다고 할 것이다. 또한 현행 이러한 법정형 체계는 관세법의 관세포탈죄가 체납처분면탈죄 내지 강제징수면탈죄보다 법정형이 같거나 더 높게 규정된 체계나 일본 세법이 규정한 조세포탈죄가 국세징수법이규정한 체납처분면탈죄보다 법정형어 더 높은 체계와도 부합하지 아니한다. 따라서 현행 조세범처벌법의 기본적 구성요건에 관한 조세포탈죄와 체납처분면탈죄의 법정형은 평등원칙에 위반되므로 조세포탈죄의 법정형을 적어도 체납처분면탈죄와 같거나그보다 높게 개정하는 것이 타당하다고 할 것이다. Following the amendment of Punishment of Tax offenses Act, the statutory punishment for tax evasion has become weaker than that for evasion of disposition on default. Meanwhile, the power of tax imposition is superior to the power of tax collection and the nature of the crime of tax evasion is greater than evasion of disposition on default. Furthermore, the current statutory punishment for tax evasion and evasion of disposition on default is incomparable to the fact that tax evasion of tariffs carries equal or higher statutory punishment than that of evasion of disposition on default. The result is conflict on the principle of the equality. Therefore, the statutory punishment for tax evasion should be revised equal or higher than that for evasion of disposition on default, to secure constitutional legitimacy.
