Particle characteristics diagnosis system (PCDS) was developed to measure submicron particle characteristics by modulation of particle beam mass spectrometry (PBMS) with scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDS). It is possible to measure the particle size distribution in real-time, and the shape, composition can be measured in sequence keeping vacuum condition. Apparatus was calibrated by measuring the size classified NaCl particle which generated at atmospheric pressure. After the calibration, particles were sampled from the exhaust line of plasma enhanced chemical vapor deposition (PECVD) process and measured. Result confirms that PCDS is capable for analyzing particles in vacuum condition.

새로운 1가 구리 전구체인 $[Cu^I(hfac)]_2(DVTMSO)$ and $[Cu^I(hfac)]_2(HD)$ (hfac=hexa- fluoroacetylacetonate, DVTMSO=1,2-divinyltetramethyldisiloxane, HD=1,5-hexadiene)를 합성하였으며, 또한 유기금속 화학증착법을 사용하여 증착특성을 확인하였다. 새로운 전구체는 기존 구리 1가 전구체와는 다르게 두 개의 Cu(hfac)가 하나의 중성리간드에 결합된 형태를 가지고 있다. 또한 새롭게 합성된 두 종류의 전구체는 기존에 알려진 1가 구리 고체 전구체에 비해 높은 안정성 및 높은 증기압을 가지고 있는 것이 확인하였다. 아울러 기존의 전구체와는 달리 새로운 전구체로 화학증착하면 막 (films)을 형성하지 않고 구리점 (dots)을 형성하는 것을 확인하였으며 이는 새로운 구조로부터 기인된 현상이라고 생각된다. 구리점의 모양은 증착온도에 따라 급격하게 변하는 것도 관찰되었다. Two new copper(I) complexes with organic ligands, $[Cu^I(hfac)]_2(DVTMSO)$ and $[Cu^I(hfac)]_2(HD)$ (hfac=hexafluoroacetylacetonate, DVTMSO=1,2-divinylte-tramethyl-disiloxane, HD=1,5-hexadiene) were synthesized and used for copper metal-organic chemical vapor deposition. In these compounds, two Cu(hfac) fragments are bonded by one neutral ligand forming unusual structure with respect to other Cu(I) complexes. The compounds exhibited relatively high volatility and stability when compared to other copper(I) precursors. By using the reported compounds as precursors, a continuous Cu layer was not formed but the Cu islands were only observed. And the shape and size of Cu islands are significantly changed as a function of the substrate temperature.

전통온돌난방의 실내 온열환경 쾌적감 평가에 관한 연구

강상우,전지현,국찬,Kang, Sang-Woo,Jeon, Ji-Hyeon,Kook, Chan 한국주거학회 2007 한국주거학회 논문집 Vol.18 No.4

The principle of Korean Traditional Housing was to be harmonized with the nature with shapes according to regional climate and materials easily available from the region. These environmentally friendly characteristics protected indoor environment from climate changes. The characteristics of Korean traditional housing to control indoor environment would be very useful for contemporary housing in that current issues, improving housing amenity and wellbeing, had basic goals same with what Korean Traditional Housing had. Though it could be found characteristics of indoor thermal environment heated by Ondol Heating System, analyses of evaluation made by occupants of the rooms were insufficient because most of the studies had been focused on the measurement of indoor thermal factors. Thus, with an evaluation of occupants for the indoor thermal comfort and an estimation of discomfort derived from the result of vertical temperature distribution, it was studied whether the agreeable indoor range of rooms, of which was Jeonju Hanok Living Experience Center, heated by Ondol Heating System corresponded to the agreeable indoor range presented in references.

기독교사회복지 연구방법에 관한 소고 -이론적 고찰 중심으로-

강상우 ( Sang Woo Kang ) 기독교학문연구회 2012 신앙과 학문 Vol.17 No.1

The Purpose of this study is to develop a Christian social welfare research method, which is based on the theoretical approach. In the present days, most of the social welfare research methods are inclined to the research method of positivism (so-called, methodolatry method + idolatry). Because the method of (logical) positivism pursues quantitative research method, it excludes concept of religion and spirituality. On the other hand, since Christian social welfare seeks the integration of faith and social welfare, applying the research method of positivism to develop a method of Christian social welfare would not be suitable. How should we approach Christian Social Welfare research method? There are three considerations to follow. (1) Method of positivism is not the only approach to this research. Since there are ``Many ways of knowing`` in social welfare, we should consider other approaches of method in order to develop the knowledge of social welfare. (2) Significantly, Christian Social Welfare has distinct academic identity based on Christian faith. (3) Many Researchers such as Ken Wilber and Edward 0, Wilson, based their world-views to integrate between their faith or belief and the academic knowledge. Therefore Christian Social Welfare research method should not be inclined to specific approach of research methods, but adhere to true academic identity. Christian social welfare researchers should base their Christian faith as their world-views. Keep in mind that as all truth is God`s truth, all research methods are God`s.

강상우(Sang-Woo Kang),최의성(Eui-Sung Choi),김동수(Dong-Soo Kim),정호승(Ho-Seung Jung),홍석현(Seok-Hyun Hong),고반석(Ban-Suk Go) 대한정형외과학회 2019 대한정형외과학회지 Vol.54 No.1

목적: 관절경적 수술을 시행받은 감염성 슬관절염 환자들에서 성별, 나이, 기저질환, 증상 발생 후 수술까지 걸린 기간, 발병 전 침습적 시술의 시행 여부, 관절 천자액의 세균 배양, Gächter 분류를 통한 세균 감염의 정도가 치료 예후에 미치는 영향에 대해 알아보고자 한다. 대상 및 방법: 2014년 6월부터 2016년 12월까지 감염성 슬관절염으로 관절경적 수술을 시행받은 51명의 환자를 대상으로 하였으며, 평균 추시 기간은 14.2±2.1개월(12-20개월)이었다. 남자가 27명(52.9%), 여자가 24명(47.1%)이며, 평균 나이는 55.1±17.6세(13-84세)였다. 수술 전 시행한 관절 천자검사상 백혈구 수가 50,000개 이상, 다형핵 백혈구 수의 비율이 95% 이상인 환자를 감염성 슬관절염으로 진단하고 수술을 시행하였다. 모든 환자에서 관절경적 수술과 수술 후 지속적인 관절 세척을 시행하였다. 결과: C-반응 단백의 초기 평균 수치는 9.55±6.76 mg/dl (1.51-31.06 mg/dl)에서 최종 평균 수치는 0.74±1.26 mg/dl (0.08-6.77 mg/dl)로 감소하였으며, 평균 C-반응 단백의 정상화 기간은 27.6±18.9일(8-93일)이었다. 관절경적 수술과 항생제 사용 후 발열, 동통, 부종 등의 임상증상이 호전되고 C-반응 단백의 수치가 0.5 mg/dl 이하로 감소하여 감염성 슬관절염의 완치 판정을 받은 환자는 51예 중 44예(86.3%)이며, 최종적으로 두 번 이상의 관절경적 수술을 시행한 환자가 5예, prosthesis of antibiotic-loaded acrylic cement 후 인공관절 치환술로 전환한 환자가 2예이다. 결론: 지금까지 문헌들에서 알려진 것처럼 증상 발생 후 수술까지 걸린 기간과 Gächter 분류에 따른 병기는 감염성 슬관절염의 치료 성공 여부에 유의하게 영향을 주었다. 하지만 이외의 인자들은 통계적으로 유의한 상관관계가 없었다. 단 관절 천자액에서 세균이 배양된 환자군은 대조군보다 유의하게 C-반응 단백의 정상화 기간이 짧아 치료 기간을 반영하는 것으로 보인다. Purpose: This study examined the effects of gender, age, underlying disease, duration after onset of symptoms, preoperative invasive procedures, bacterial culture of joint fluid, and stage of infection by the Gächter classification on the prognosis of patients with infectious knee arthritis who underwent arthroscopic surgery. Materials and Methods: From June 2014 to December 2016, 51 patients who underwent arthroscopic surgery for infective knee arthritis were enrolled in this study. The average follow-up period was 14.2±2.1 months (range, 12-20 months). The subjects were 27 men (52.9%) and 24 women (47.1%), with an average age of 55.1±17.6 years (range, 13-84 years). A preoperative evaluation of the joint aspiration with a count of more than 50,000 leukocytes and a polymorphonuclear leukocyte count of 95% or more was performed. All patients underwent arthroscopic surgery and postoperative continuous joint irrigation. Results: The initial mean value of the C-reactive protein decreased from 9.55±6.76 mg/dl (range, 1.51-31.06 mg/dl) to a final mean of 0.74±1.26 mg/dl (range, 0.08-6.77 mg/dl); the mean duration of C-reactive protein normalization was 27.6±18.9 days (range, 8-93 days). Among the 51 patients who received arthroscopic surgery and antibiotics, 44 patients (86.3%) with infectious knee arthritis completed treatment with improved clinical symptoms, such as fever, pain, and edema, and the C-reactive protein decreased to less than 0.5 mg/dl. Finally, 5 cases were treated with two or more arthroscopic operations, and 2 cases were converted to arthroplasty after prosthesis of antibiotic-loaded acrylic cement. Conclusion: The duration of surgery after the onset of symptoms and the stage according to the Gächter classification are important prognostic factors for predicting the successful treatment of infectious knee arthritis. On the other hand, the other factors were not statistically significant. Nevertheless, patients with bacteria cultured from the joint fluids appear to reflect the treatment period because the period of normalization of the C-reactive protein is shorter than that of the control group.

성경적 세계관에 근거한 사회복지실천모형: 성경해석을 중심으로

강상우 ( Sang Woo Kang ) 기독교학문연구회 2011 신앙과 학문 Vol.16 No.1

The purpose of this study is to develop a social welfare practice model based on the perspective of the Biblical worldview. 1) The Bible is the primary text on the Christian social welfare practice model because the Bible is the Word of God. Therefore, the social welfare practice model is based on Biblical worldview that should be followed from the Bible. If we should act according to the social welfare practice based on the perspective of the Biblical worldview, we must adhere to the Bible more than to the logical-positivism methodology and we must treat social welfare based upon a faithful belief in the Bible. 2) The Bible tells us about components of the social welfare practice model. (a) God is the origin of social welfare practice. (b) The commands of social welfare practice are the Great Commandment(``to love God and neighbor``), the Great Commission(``to preach``) and the Cultural Mandate(``to live as stewards``). (c) The medium of social welfare practice is the proclamation of the Word of God(κηρυγμα: kerygma). (d) The subjects of social welfare practice are saints, church, Christian NGOs. (e) The means of practice are Education(διδαχη: didache), fellowship(διακονια: diakonia), and Service(κοινωνια: koinonia). (f) The objects of practice are human being as an image of God and a local community. The world created by God is a practical setting.(κοσμοζ: kosmos) (g) And the goal is to make the Kingdom of God(βασιλεια τομ θεου). 3) I suggest a Christian social welfare practice model.
