박관수,정기훈,김효언,정정권,윤규호,전인성 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.1

Necrotizing fasciitis is defined as infectious disease showing extensive necrosis of the superficial fascia with widespread involvement of the surrounding tissues and concurrent systemic toxicity. It is found commonly in the extremities, the trunk and the perineum, but shows extremely rare occurrence in the well vascularized area such as head and neck area. Occurred in the head and neck area, it is called "cervicofacial necrotizing fasciitis" (CFNF). It is a fatal disease which carries a mortality rate up to 60%. Early diagnosis, aggressive surgical debridement of necrotic tissues and massive antibiotics therapy are essential for achieving a favorable outcome. We present a case of cervicofacial necrotizing fasciitis in 35-year-old male patient with literature review.

Rician 페이딩 채널에서 WATM 셀의 성능 개선에 관한 연구

조성언,박정현,백승선 順天大學校 1998 論文集 Vol.17 No.1

This study has analyzed theoretically the effect of fading to design effective wireless ATM system. The CNR, CLR, and CER of wireless ATM system adopting FEC coding and diversity reception techniques have been derived in fading environment. From the results, CLR in the HFEC which puts more importance on coding gain than coding rate, it show(62, 32, 5)FEC coding having higher coding gain is more adequate. And also, it has to consider CER and MaxU data together in the PFEC performance, because emphasizing the error correction ability to lessen CER cause inefficient use of channel by the added redundancy bit. (438, 384, 6) FEC coding is more appropriate in the CER and MaxU. it is showing the CER and MaxU value when dividing (438, 384, 6) FEC. The more division is the less CER value in the CER, but in the MaxU, when a wires ATM cell is divide by more then two WATM cell, it leads to increase of overhead due to more header transmission, and finally to relatively poor MaxU value in the case of going over the certain bound of CNR value. (240, 192, 6) FEC code is proper than (438, 386, 6) code when considering CER and MaxU data in the payload division. Using diversity technique to wireless ATM cell header improves MRC to about 1.7 dB of Eb/No than SC under the Rayleigh fading environment, and to 2 dB of Eb/No under Rician fading (K=5). Also using the diversity technique to wireless ATM cell Payload under Rician fading environment improves MRC to 3dB of Eb/No than SC in both case of K=5 and K=10.

In this study, we have developed the simulation tool in order to investigate driving trajectory of AGV for container transport. AGV for container transport is different from the indoor AGV in that it is a large size structure at being loaded the weight of 40 ton. And AGV for container transport is applied to front wheel steering, rear wheel steering, all wheel steering, and crap steering. Therefore, we have developed the simulation tool considering dynamic problems and a center of turning in accordance with fourth ways of steering mode. As the result of this study, we have confirmed that this tool is useful and cost-effective in the dynamic analysis or large size vehicles. Also, it is useful to calculate the minimum radius of turning for large size vehicles.

이정언 한국항공대학교 경영연구소 2000 경영연구 Vol.7 No.1

본 연구는 가치관이라는 광범위한 주제를 통하여 직무가치관이 조직 성과와 어떠한 관련성을 맺고 있는지 이론적으로 고찰하였다. 특히 직무가치관에 대한 기존의 연구들이 단순한 의식조사의 수준에 머물러 있는 한계를 고려하여 일에 대한 가치관의 재차원들을 프로테스탄트 직업윤리, 개념구성 및 영향오인 연구, 국가간 차이에 따른 연구, 가치합치성 관련 연구 등으로 세분화하여 관리차원의 합의점을 이끌어 내고자 하였다. 본 연구에서는 추후의 보다 발전된 이론적·실증적 연구를 위하여 가치관의 차원 구분, 일에 대한 가치관의 차이로 나타날 수 있는 결과, 구성원들의 다양한 가치관을 어떠한 방법으로 조직의 성과 향상에 기여할 수 있도록 할 것인지에 대한 대안을 개략적으로 제시하였다. Values axe important to understand the organizational members behavior because they lay the foundation for understanding of attitudes and motivation as well as influencing their perceptions. Organizational managers are how much more salient to the issues of work values than before. Unfortunately, however, we lack either theoretical or empirical studies on work-values which may help solving many of the human resources management problems in the contemporary Korean company. This study aims at developing and theoretically testing a comprehensive studies of work values derived from the prior theoretical studies on work values. And this study theoretically seeks to understand the relationship between work values and job-related performances. In sum, this study suggested some theoretical and managerial implications for organizational behavior and human resources management in regards to work values.

남언정,이종명,김건우,김신우,김능수 경북대학교 병원 2003 경북대학교병원의학연구소논문집 Vol.7 No.1

Objectives : This study was performed to investigate the relationship between cell counts, supernatant and lysate ECP levels in sputum, and physiologic markers in adult asthmatic. Methods : Twenty-two patients with mild to moderate persistent asthma, ten patients with acute exacerbated asthma and nine healthy subjects were enrolled. Sputum was induced by inhalation of hypertonic saline, and homogenized with 0.1% dithiothreitol. A total and differential cell was measured in supernatant fluid. Cell pellet was centrifuged, and ECP(supernatant ECP) was measured in supernatant fluid. Cell pellet was reacted with a cellular lysis buffer to release cell-associated ECP, and ECP(lysate ECP) was measured again in supernatant fluid. The ratio of supernatant to lysate ECP was calculated as an index of eosinophil degranulation. Spirometry and methacholine bronchial challenge tests were also performed as physiological markers of asthma. Results : The patients with acute exacerbated asthma showed significantly higher percentage of sputum neutrophil, eosinophil count, concentration of sputum supernatant ECP and ratio of supernatant to lysate ECP than those of normal controls and stable asthmatic patients(p<0.05, respectively). The level of sputum supernatant ECP, supernatant/lysate ECP ratio, and percentage of neutrophil showed negative correlations with pulmonary functions, but no correlations with a degree of bronchial hyperresponsiveness. There was no significant correlations between of serum ECP level and physiological parameters. Conclusion : These results suggest that both neutrophils and eosinophils play roles in the exacerbation of asthma. The sputum supernatant/lysate ECP ratio might be valuable in assessment of activation status of eosinophils in various hypereosinophilic conditions or diseases.

Inhalation of a foreign body into the respiratory passage is a frequent in children and sometimes fatal accident. It can produce different symptoms and signs, which may be confused with esophageal foreign body. On occasion, it can be not only followed by some pulmonary complications, but also it is often delayed to be removed Recently, we experienced a bronchial foreign body, which was misdiagnosed a esophageal foreign body. It was successfully removed via ventilating bronchoscope, after esophagoscopy and reevaluation of a foreign body in operating room. We report this case with review of the literacture.
