지방자치단체의 전략기획-선택인가 필수인가 : 미국 지방정부의 교훈
김성준,김용운 한국행정연구원 2003 韓國行政硏究 Vol.12 No.4
본 논문은 전략관리의 핵심적인 과정으로서 민간부분과 선진국의 정부부문에서 폭넓게 수행되고 있는 전략기획(strategic planning)이 근래 우리나라 공공부문과 지방자치단체에서 논의되고 있는 조직관리 개선에 어떤 방식으로 그 역할을 할 수 있는지 가능성을 탐구한 것이다. 이에 미국 지방정부를 중시의로 전략기획의 구체적인 수립방법과 도입 및 수정과정, 그리고 제도정착의 성공요인들을 분석하였다. 이를 통해 우리나라 지방자치단체에서 전략기획을 도입할 때 고려해야할 시사점으로, 1) 전략기획의 궁극적인 목적은 전략계획의 수립 자체가 아니라 조직 구성원의 전략적 사고와 행동을 유인하여 궁극적으로 조직의 기획역량을 제고하는 데 있다는 점, 2) 전략기획 과정에서 환경 및 이해관계자에 대한 분석이 충분히 이루어져야 한다는 점, 3) 마지막으로 전락기획의 성공적인 추진을 위해서는 지방자치단체장의 적극적·참여적 리더쉽과 조직내 커뮤니케이션의 활성화가 핵심적인 요인이라는 것을 제시하고 있다.

For large reciprocating compressors in parallel operation, an analytical study has been carried out on the gas pulsation in associated discharge piping lines. Since the pressure pulsation at a valve, valve dynamics, and the gas flow rate through the valve are interrelated, affecting one another, these need to be solved simultaneously. Acoustic transfer matrix method, which relates acoustic pressure and velocity at one location to those at another location, has been adopted to calculate the effect of the gas flow at one valve location on the gas pulsation at other valve locations.

Spam refers to any unwanted or unauthorized commercial messages. Spam may violate individuals' privacy or other personal rights. Spam often overloads network traffic, wastes individuals' time, lowers productivity and quality of life, and limits the trustworthiness of Internet businesses. As the use of mobile messaging services and social networking services both on mobile communication networks and on the Internet increase, newer and more complex types of IT applications and services are often used as new means of spam. In this research, the characteristics and impact of new and future forms of spam, and anti-spam related policies and regulations are surveyed. To improve the effectiveness of anti-spam policies and regulation? in Korea, adding a definition of spam in the law, changing policies to focus on the 'type of services' rather on the medium of transmission, and redefining the scope of 'commercial purposes' in Korean law are suggested.

Conceptual design of scroll expander and scroll compressor for 10 ㎾-class Stirling engine utilizing solar energy as heat source has been carried out to estimate the applicability of scroll mechanism for Stirling cycle. CO2 was chosen as working fluid, since it has lower expansion index and higher density among probably usable gases. Gas temperature at the expander inlet was sel at 700℃, and that at the compressor inlet was at 40℃. System efficiency reached maximum at the pressure ratio of about 2.5. and the peak efficiency increased with increasing high side pressure. Due to safety concern, the pressure condition of 6 ㎫/2.5 ㎫ was chosen as design condition. Orbiting scroll members for the expander and compressor were designed to have double-sided structure in order to reduce the overall scroll size and to cancel out the axial gas forces acting on the orbiting scroll base plate- By parametric study on the scroll profile, smaller possible size for the scroll members was obtained. With the shaft speed of 3600 rpm, the shaft output of the designed scroll expander was calculated to be 45.4 ㎾, while input power for the scroll compressor was 34.5 ㎾, yielding 10.9 ㎾ for the output power of the Stirling engine. System efficiency was estimated to be about 7.3%, and overall efficiencies of the scroll expander and compressor were around 84.1% and 88.3%. respectively.
신생아 분변에서 분리한 Enterococcus faecalis의 내산성 및 내담즙산성 비교

In this study, we investigated the probiotic candidates of Enterococcus faecalis isolated from infant feces. Fecal samples were inoculated on modified MRS (pH 5.4) agar and Blood-liver containing antibiotics agar. Total 10 isolates were identified through Gram stain, KOH test, catalase test, and 16S rDNA analysis. And these isolates compared to resistance against artificial gastric juice (pH 2.5, 1,000 unit pepsin) and bile salts (0.3% Oxgall). Especially, strain SJ10 survives at a level of 7.84 log CFU/ mL under 0.3% bile salts. Strains SJ1, SJ6, SJ7 and SJ10 were found to be the least acid resistance with a viable cells (SJ1: 6.97 log CFU/mL, SJ6: 7.19 log CFU/mL, SJ7: 7.02 log CFU/mL and SJ 10: 7.07 log CFU/mL, respectively). Further in vitro and in vivo studies should be evaluated with these isolates before claiming probiotic characteristics.
808 nm 파장의 고출력 근적외선 레이저 조사 시 돼지 조직의 천공 특성 연구
김성준(Seongjun Kim),조지용(Jiyong Cho),최재순(Jaesoon Choi),이돈행(Don Haeng Lee),김중경(Jung Kyung Kim) 대한기계학회 2013 大韓機械學會論文集B Vol.37 No.9
소화기 내시경에 장착된 808 nm 파장의 고출력 근적외선 레이저를 장벽에 조사하여 병변을 제거할 수 있는 치료용 의료기기의 개발을 목적으로 레이저-조직 상호작용에 관한 기초 실험을 진행했다. 레이저 출력 3~12 W, 조사 시간 5~20 s 범위에서 각 변수의 증가에 따라 천공 깊이가 1~4 mm 범위에서 선형적으로 증가했다. 돼지에서 적출한 각 장기에 대한 레이저 조사 시 천공 깊이가 조직 특성에 따라 달라짐을 확인했다. 온도 측정 결과로부터 열에너지가 레이저 조사 지점에 집중되고 심부로 전달되어 주변 조직의 열손상은 방지됨을 알 수 있었다. 본 연구 결과는 위, 대장 등의 소화기 조직에서 일정한 절개 깊이를 얻기 위해 필요한 근적외선 레이저의 구동 조건을 결정하는데 활용될 수 있다. A fundamental study on laser-tissue interaction was conducted with the aim of developing a therapeutic medical device that can remove lesions on the intestinal wall by irradiating a high-power 808-nm infrared laser light incorporated in an endoscopic system. The perforation depth was linearly increased in the range of 1~4 mm in proportional to laser output (3~12 W) and irradiation time (5~20 s). We demonstrated that the perforation depth during laser irradiation was varied according to the tissue property of each extracted porcine organ. The measurement of the temperature distribution suggests that the energy is localized in the irradiation spot and transferred to deep tissue, which protects the surrounding tissue from thermal injury. These results can be used to set the driving parameters for a laser incision technique as an alternative to conventional surgical interventions.

Aesthetic preference of residents for interior finishing materials is an important factor to consider in the process of determining finishing materials, but the related research is limited. In addition, in the case of multi-family houses, designers cannot provide an alternative that meets the preference of residents because designers create an interior design by guessing the preferences of the residents. This study proposes a design support tool that collects and analyzes review data of Airbnb and provides designers with interior design cases preferred by residents. The proposed design support tool extracts user preferences and material information about Airbnbs interior design case through text mining and deep learning and recommends them to the designer. A case study was conducted on 858 rooms in Airbnb located in Seoul to verify the proposed design support tool. The results indicate that it was possible to provide similar cases preferred by a large number of users to the designer, and the designer could modify the design based on recommendations.
