AbstractThe Korean Customer Satisfaction Index made from KMAC is an national economic indicator of customer satisfaction with the quality of goods and services avaliable to household consumers in Korea. Samsun Everland was awarded grand prize 4 times for customer satisfaction mangement contest from KMAC. This case study is the results of analysis of the Everland's customer satisfaction operation stystems, philosophy, the trend analysis of ESI & CSI. When we review this case study, we find out of the basic framework of customer satisfaction mangement of service industry.

Etofenprox저항성 복숭아혹진딧물(Myzus persicae)의 thiamethoxam과 fenpropathrin에 대한 섭식행동 관찰
조창욱,박초롱,윤규식,강민아,권혜리,석희봉,강은진,서미자,유용만,윤영남,Jo, Chang-Wook,Park, Cho-Rong,Yoon, Kyu-Sik,Kang, Min-A,Kwon, Hae-Ri,Seok, Hee-Bong,Kang, Eun-Jin,Seo, Mi-Ja,Yu, Yong-Man,Youn, Young-Nam 한국응용곤충학회 2009 한국응용곤충학회지 Vol.48 No.4
피레스로이드계에 속하는 etofenprox에 대하여 저항성과 감수성을 띄는 복숭아혹진딧물이 다른 살충제에 대한 저항성 여부를 살충제 처리 및 EPG 기술을 이용하여 비교하였다. Fenpropathrin에 대한 두 개체군간의 살충율을 비교하기 위하여 추천농도(50ppm)로 처리는 48시간 후, 저항성 개체군은 28%, 감수성 개체군은 29%의 살충 활성을 보여주었고 $LC_{50}$ 값은 저항성 개체군이 193.15 ppm 감수성 개체군이 93.46 ppm이었다. Thiamethoxam의 추천농도(100 ppm)로 처리한 결과 48시간 후, 저항성 개체군은 57%, 감수성 개체군은 79%의 살충활성을 보여주었고, $LC_{50}$ 값은 저항성 개체군이 3.17 ppm 감수성 개체군이 30.34 ppm이었다. 두 개체군의 살충제에 노출시킨 후, 섭식 행동차이를 알아보기 위하여 EPG 기술을 이용하여 살충제 처리 전과 후로 나누어 섭식행동을 관찰하였다. Thiamethoxam과 fenpropathrin 모두 복숭아혹진딧물 두 개체군간에 조사한 섭식행동패턴 모두에 있어 큰 차이를 나타내지 않았으나, etofenprox에 저항성을 나타내는 개체군이 동일한 계열의 피레스로이드계 살충제인 fenpropathrin에 대해 약제에 노출된 이후에도 섭식을 지속하는 경향을 나타내 교차저항성의 가능성을 보여주었으나, 다른 계열의 살충제인 thiamethoxam에 대한 복합저항성은 확인되지 않았다. To investigate resistance of Myzus persicae, which is resistant to etofenprox belonging to pyrethriods, to other insecticides, fenpropathrin and thiamethoxam, mortality and $LC_{50}$ values for these two insecticides against the etofenprox-resistant and -susceptible populations were obtained and EPG analysis for feeding behaviors of thiamethoxam or fenpropathrin treated and non-treated M. persicae was conducted. For fenpropathrin, mortality after 48 h treatment was 28 and 29%, respectively for the resistant and susceptible population. The $LC_{50}$ value was 193.15 and 93.46 ppm, respectively. For thiamethoxam, mortality after 48 h treatment was 87 and 57%, respectively for the resistant and susceptible population. The $LC_{50}$ value was 3.17 and 30.34 ppm, respectively. There was no significant difference in feeding behavior between fenprorpathrin treated and non-treated M. persicae. They showed a continuous feeding pattern. However, contact signal frequency increased in the thiamethoxam treated M. persicae 1 hour after treatment and significant difference was shown.

The white-rot fungus (Trametes versicolor) and brown-rot fungus (Tyromyces palustris), which cause damage to a variety of wooden cultural properties and buildings, such as drying of the wood tissue, decay and cracks, sponge, and discoloration, give rise to serious structural and aesthetic problems. Moreover, pest termites (Reticulitermes speratus kyushuensis Morimoto) can cause damages like hollowing the outdoor beams or pillars of wooden buildings and finally causing such buildings to collapse due to the termites' destruction of the inside of the beams or pillars, leaving only a thin layer on their surfaces. This study was conducted to determine the impact of the wood-decay fungus, a representative damage-causing microorganism, and of insects and termites on the termite ecology. The damage ratio was calculated as the weight of the timber, and the overall total mass was reduced from two kinds of rot fungi. The white-rot fungi reduced the total wood mass, but the brown-rot fungi were observed to have had an increasing tendency to do so. The wood mass was measured after drying to determine the destruction capacity of termites. As a result, the wood mass consumed by the brown-rot fungi was shown to be greater. 백색부후균(Trametes versicolor)과 갈색부후균(Tyromyces palustris)은 목조문화재 및 건축물 등의 목재 조직의 건조, 부패과 균열, 스펀지화, 변색 등 다양한 손상을 발생시켜 구조적, 미학적인 관점에서 심각한 문제를 나타내고 있다. 그리고 가장 피해를 많이 주는 해충인 흰개미(Reticulitermes speratus Kyushuensis Morimoto)는 목조건축물의 옥외 기둥이나 대들보 등의 표층을 얇게 남겨두고 내부를 침해함으로써, 결국은 속이 빈 기둥이 되어 건축물이 무너져버리는 피해를 줄 수 있다. 대표적 피해 미생물인 목재부후 균이 흰개미의 서식에 미치는 영향을 파악하기 위하여 부후균이 만연된 곳에 흰개미를 넣어 공존 가능성을 실험해 보았다. 목재의 중량으로 피해율을 산정한 결과, 전반적인 총질량은 두 종류의 부후균에서 모두 감소하였다. 목재의 질량은 백색부후균에서는 모두 감소하였으나, 갈색부후균에서는 오히려 증가한 경향을 볼 수 있었다. 그리고 섭식량을 측정하기 위한 목재의 건조 후 질량에서는 갈색부후균에 넣었던 목재의 질량 감소가 더 크게 나타났다.

Osteochondroma is a benign tumor that is frequently developed in axial skeleton but rare in TMJ. 61-year old female patient visited local dental clinic with left TMJ crepitus on chewing, trismus and hearing discomforts. She was referred with a tentative diagnosis of TMD. We performed clinical and radiographic examination and could observe large radiopaque lesion at left TMJ. Excisional operation was performed. It was diagnosed finally with a osteochondroma.

The purpose of this thesis is to increase the recognition of POS system, and suggest the preparation efforts of preceding conditions for efficient operations of POS system in Korea. Good information is a vital ingredient in the planning, operation, and control of logistics systems. With the rising popularity of the computer in businesse activities, it has become the caretaker and manipulator of a lage portion of an organization's operating-information system. The system generates information that is used by a wide range of organizational personnel, from top management to operative employees and is used for the purpose of planning the logistics system and for its operation and control. The system itself has three basic sections : (1) the input section, (2) the computing section, (3) the output section. The complexity of the system, whether computerized or manual, or fast or slow, depends on management's need to know various types of information for decision-making purposes, the form of the information and how quickly it mist be made available. Information systems are becoming so inportant to good logistics planning and control that management has given a special organizational place to its care and maintenance. Additionally, through Point-of Sales(POS) computerized terminals, retailers are now capable of instantaneously completing paperless financial transactions associated with retail purchases through an Electronic Funds Transfer System(EFTS), which links banking and credit institutions with retail establishments.

이전에 정중흉골절개를 통해 심장 수술을 받았던 환자중 15명이 우측 개흉술을 통해 승모판 재수술을 받았다. 저자들은 승모판 재수술시 우측 개흉술을 선택하였다. 이는 유착이 없는 흉강을 통하기 때문에 심장과 주요혈관의 손상을 피할 수 있고, 상하대정맥 삽관이 용이하고, 약간의 박리로 좌우심방으로 접근이 가능하며, 수술시야가 매우 양호하기 때문이다. 또한 대부분의 심낭막을 박리하지 않기 때문에 출혈이 있을시 곧 흉관을 통해 배출되거나 흉강내로 나가심 압전을 일으킬 소지가 없다. 동맥도관의 삽관은 13예는 상행대동맥에 2예는 대퇴동맥에 했다. 정맥도관의 삽관은 초기에는 우심방을 통해 상하대정맥에 각각하고 올가미를 하였으나 후기에는 올가미 없이 삽관하거나 90$^{\circ}$각진 도관을 우심방에 단일삽관하였다. 수술중 심근보호를 위해 심정지액을 간헐적으로 사용하였고 저체온법은 저자들이 보통의 심 장수술시 주로 사용하는 25~3$0^{\circ}C$ 보다 5$^{\circ}C$ 정도 더 낮추어 시행하였다. 심실제세동은 1예는 내부패들 (Internal Paddle)을 10예는 소독된 외부패들(External Paddle)을 사용하였으며 4예에서는 체온을 높임으로 자연적으로 심박동이 돌아왔다 수술후 호흡기는 48시간 이내에 제거할 수 있었고 폐 합병증은 없었다. 1명의 환자가 술후 10일째 갑작스런 심실빈맥으로 사망하였고 나머지 14예는 합병증 없이 퇴원하였다. A right thoracotomy was used for the reoperation or mitral valve of 15 patients who had previously undergone a cardiac operation through a median sternotomy. In our experience. this approach provided dn excellent exposure of the nlitral valve and easy cannulations of both cavie with minimal dissection, ilvoiding any damage of cardiac and major vessels during re-sternotomy Arterial cannulation was performed in the ascending aorta in 13 patients And in the femoral artery in 2 patients. In earlier cases, venous cannulation was done in the SVC And IVC through the right atrium and snared. In later cases, this could be done without snaginly of both cavae or by placing a silgle light-angled catheter into the right atrium. Crystalloid cardioplegic solution was infused for myocardial protection. Hypothermia was controlled at 20\ulcorner$25^{\circ}C$. For defibrillation, internal paddles were used In one patient while sterilized external paddles were used in 10 patients. In the remaining four patients. however. the heart beat spontaneously The respirator could be weaned within 48 hours alter the operation and no pulmonary complication was observed. One out of the 15 patients expired due to sudden attack of ventricular tarchycardid developed ten days after the operation, but the rest of the patients were discharged with good condition.
