The Church as a Public Face of Agape

전영호 동국대학교 동서사상연구소 2016 철학·사상·문화 Vol.0 No.22

In that religion is the system of most fundamental belief and interpretation of the world and life, it is the unity as a whole encompassing philosophy, thoughts and culture. But all religions exist not as the abstract ‘religion in general,’ but as an individual which is concrete substance existent unified with particular thoughts, particular region and particular culture. The reflection of the character and reality of religion united in specific human existential circumstances is therefore necessary for those who seek to find out philosophy and thoughts in a particular religion. Under the questioning like this, the present article aims to analyze and criticize the actuality of Christianity in North America and South Korea from various perspectives, on the one hand to anatomize the problems of Christianity which recently became a target of more harsh criticism than ever and on the other hand to ascertain what the essence of the church visibly representing the Christianity as religion could be, in order to understand what the Christianity as religion is and should be.

EXPERIMENTAL INVESTIGATION TO ANALYZE THE EFFECTS OF OIL DILUTION ON UNINTENDED ACCELERATION IN A DIESEL ENGINE

전영호 한국자동차공학회 2020 International journal of automotive technology Vol.21 No.5

Due to the gradual reinforcement of emission regulations, exhaust gas after-treatment systems have become more complicated, and various engine control algorithms have been applied to diesel engines. However, the misuse of advanced exhaust gas after-treatment systems could cause additional problems. For instance, diesel vehicles that use of a diesel particulate filter (DPF) generally require periodic active regeneration. While operating active regeneration by in-cylinder postinjection, the fuel impinging on the cylinder wall would become the cause of oil dilution. Furthermore, if, in the event of excessive oil dilution, engine oil overflows in the engine oil pan, engine stalling or unintended acceleration (engine over-run) can occur, as lube oil flows into the combustion chamber through the intake manifold. The present study tested engine overrun by overflowing engine oil diluted with fuel on various engine operating conditions and clarify the engine control factors effect on engine stalling or unintended acceleration using regression analysis. Vehicle tests based on engine test analysis were also conducted to evaluate and reproduce the influence of unintended acceleration by automotive lube oil backflow in real driving. Vehicle test results indicate that unintentional acceleration could occur due to oil dilution, which put the driver at risk.

전영호,김성돈 한국경영공학회 2018 한국경영공학회지 Vol.23 No.4

Most electric products produced during the manufacturing process are produced after design and mass production under a given control standard. In particular, the development phase should present the criteria for the production process by setting appropriate limits based on the performance being targeted. Even if the standard of performance is set considering the performance of the process, measuring the performance of the product after actual production results will cause nonconformities with the expected results. Among the performance of electrical products, Energy standards represented by energy consumption efficiency continue to be of importance, and are mandatory standards that correspond to national standards in most countries. Therefore, statistical quality control of these standards shall basically have a large number of test equipment for each product, ensure sufficient test time and continuous sampling of product samples. In the end, companies that produce and sell electric appliances are striving to control mass production at a great cost, but this is not acceptable. This study presents basic characteristics of the energy efficiency of electrical products and proposes and conducts a case study on statistical production control methods for performance variation across products under the standards about domestic and international regulations.

This study was designed to decide the effectiveness after gastric carcinoma operation. A total of 256 cases of the resected stomachs examined at a certain hospital during the period of 4 years from January 1974 to December 1978 were classified according to Lauren's method based on the histological investigation. Lauren classified the gastric carcinoma into two types : intestinal type carcinoma and diffuse type carcinoma. When classified by Lauren's method, intestinal type carcinoma is more effective than diffuse type carcinoma after operation.

등온으로 가열되는 경사진 평판위의 충류 자연대류 유동에서 2차적인 정규 와동의 발생조건을 이론적으로 조사하였다. 본 연구를 위하여 선형 안정성 이론과 크기위수 해석을 근거로 교란량들의 주 흐름방향의 변화를 고려하는 전파이론이 적용되었다. Prandtl수가 매우 큰 극한 경우에 대하여 임계 조건을 구하여 본 결과, 그 임계 조건은 기존의 연구결과들보다 물에 대한 실험치에 보다 접근함을 보였다. A theoretical study for analyzing onset conditions of secondary flow in the form of vortex rolls in the primary natural convection over an inclined isothermally heated plate is carried out by employing the order-of-magnitude analysis under linear stability theory. For this purpose the propagation theory considering the variation of disturbances in the main flow direction is tested here. The present critical conditions for the infinite Prandtl number are found to approach the experimental data of water more closely than other theoretical results.

보증 하에 판매되는 제품의 적정 예방정비계획

全永鎬 弘益大學校 1989 弘大論叢 Vol.21 No.2

A warranty is a contractual obligation incurred by a producer in connection with the sale of a product. The warranty specifies that producer agrees to remedy certain failures in the product sold. There have been many articles dealing with warranties. but they have studied about optimal warranty cost for the warranty period. In this study, a optimal preventive maintenance time interval is computed. The optimal preventive maintenance time interval minimizing warranty cost for the warranty period is discussed. It is assumed that failure rate is increasing and the failure rate after preventive maintenance or corrective maintenance lies between good as new and bad as old.

이동통신 단말기의 감성만족 요소간 인과관계에 관한 연구

In general, causal relationship for theoretical concepts is hypothesized based on precedent studies and tested by a structural equation model. However, when theoretical backgrounds are scarce or absent, the causal relationship is hypothesized operatively by the purpose and scope of research and tested by overall goodness-of-fit indices such as GFI and RMR. Such a causal relationship can't be most appropriate statistically because it is selected as specific relationship from researcher's view among possible causal relationships. Therefore, this study is to propose a procedure for identifying the causal relationship that produces the best GFI among possible causal relationships for theoretical concepts.

Biotinoyl Domain of Human Acetyl-CoA Carboxylase: Structural Insights into the Carboxyl Transfer Mechanism

전영호,Chung-Kyung Lee,정해갑,류경석,Jae Il Lee,Chaejoon Cheong 한국자기공명학회 2008 Journal of the Korean Magnetic Resonance Society Vol.12 No.1

Acetyl-CoA carboxylase (ACC) catalyzes the first step in fatty acid biosynthesis: the synthesis of malonyl-CoA from acetyl-CoA. As essential regulators of fatty acid biosynthesis and metabolism, ACCs are regarded as therapeutic targets for the treatment of metabolic diseases such as obesity. In ACC, the biotinoyl domain performs a critical function by transferring an activated carboxyl group from the biotin carboxylase domain to the carboxyl transferase domain, followed by carboxyl transfer to malonyl-CoA. Despite the intensive research on this enzyme, only the bacterial and yeast ACC structures are currently available. To explore the mechanism of ACC holoenzyme function, we determined the structure of the biotinoyl domain of human ACC2 and analyze its characteristics using NMR spectroscopy. The 3D structure of the hACC2 biotinoyl domain has a similar folding topology to the previously determined domains from E. coli and P. Shermanii, however, the ‘thumb’ structure is absent in the hACC2 biotinoyl domain. Observations of the NMR signals upon the biotinylation indicate that the biotin group of hACC2 does not affect the structure of the biotinoyl domain, while the biotin group for E. coli ACC interacts directly with the thumb residues that are not present in the hACC2 structure. These results imply that, in the E. coli ACC reaction, the biotin moiety carrying the carboxyl group from BC to CT can pause at the thumb of the BCCP domain. The human biotinoyl domain, however, lacks the thumb structure and does not have additional non-covalent interactions with the biotin moiety; thus, the flexible motion of the biotinylated lysine residue must underlie the “swinging arm” motion. This study provides insight into the mechanism of ACC holoenzyme function and supports the "swinging arm" model in human ACCs.

성인에서 비타민 D 및 알레르기질환과 백내장의 연관성

전영호,송영민 대한가정의학회 2020 Korean Journal of Family Practice Vol.10 No.3

연구배경: 최근 알레르기질환의 원인이 비타민 D 부족에 의한 면역장애 때문이라는 “비타민 D 가설”이 제시되고 있다. 또한, 아토피피부염의 합병증의 하나로 알려진 백내장은 비타민 D와의 연관성에대한 여러 논문이 발표되었다. 알레르기질환과 백내장은 비타민 D와 연관성 논란이 있으나 두 질환간의 연관성에 관한 논문은 미비한 실정이다. 이에 본 연구는 국민건강영양조사 자료를 이용하여 알레르기질환과 백내장의 연관성에 대해 알아보고자 한다. 방법: 국민건강영양조사 자료 중 2010년 자료를 이용하였다. 혈액검사를 통해 25(OH)D를 측정하였고, 자기 기입식 설문, 문진, 신체검사를 통하여 개인 특성을 파악하였다. 혈액검사 및 설문, 문진,신체검사를 시행하지 않은 자는 제외하였다. 로지스틱 회귀분석으로 알레르기질환 및 관련인자와 백내장의 상관관계를 알아보았다. 결과: 2010년 국민건강영양조사에서 알레르기비염, IgE, 비타민 D는백내장과 연관성을 보였다. 그러나 아토피피부염, 천식, Zn는 백내장과 연관성을 보이지 않았다. 결론: 한국 성인에서 알레르기비염이 없고 혈중 IgE와 비타민 D가높을수록 백내장의 유병률이 높은 모습을 보였다. Background: “Vitamin D hypothesis” is a recently suggested theory that the allergic diseases caused by immunodeficiency develop due to Vitamin Ddeficiency. Moreover, vitamin D is reportedly associated with cataracts, a complication of atopic dermatitis. Despite this association of vitamin D withallergic diseases and cataracts, there is little research on the association between these two diseases. Therefore, we aimed to investigate therelationship between allergic diseases and cataracts. Methods: We used data from the 2010 Korea National Health and Nutrition Survey and measured 25-hydroxyvitamin D (25(OH)D) levels by performingblood test. Data on individual characteristics were obtained using self-reported questionnaires, interviews, and physical examination. Those withinsufficient data pertaining to blood tests and questionnaires, medical history, and physical examination were excluded. Logistic regression analysiswas used to examine the correlation between allergic diseases (and related factors) and cataracts. Results: We found that allergic rhinitis, IgE, and vitamin D were associated with cataracts. However, atopic dermatitis, asthma, and Zn were notassociated with cataracts. Conclusion: The prevalence of cataract in was greater among Korean adults with no allergic rhinitis and those with higher serum IgE and vitamin D levels.
