Many enterprises have been putting importance of business administration internal management rather than the customers as having been unable to rapidly cope with the market change under the environment which we call $quot;the age of uncertainty$quot;. The wall between the hotel divisions in the traditional system has blocked the flow of information. As the system has been fatter, the greater amounts of indirect expenses have been paid. The concept of Business Process Reengineering by Michael Hammer is that $quot;the whole organization systems should be basically redesigned based on the business process for epochal increase in the key result of business administration.$quot; BPR is not the same as a renewal movement in existing systems or business methods. Hotels should consider the fundamental questions such as $quot;the reason for the existence of the system$quot;, $quot;the reason for the performance of each division$quot; and $quot;why such methods have been adopted at the time of business process$quot;. In other words, this study has been aimed to examine how BPR has been applied to hotels, human service enterprises in which the satisfaction of the customers is the good itself differ from other general enterprises of manufacture since BPR starts from $quot;Customers Value$quot;, what we call CS. Though Hotels have been realizing the importance of the thought based on the CS already, the application of BPR in general hotel business process has not yet been realized. As one of the methods of coping with such of the introduction of BPR concept should be seriously required to be applied as one of the innovation of hotel business administration.

Purpose: We retrospectively studied the outcomes of the shoulder impingement syndrome for the treatment of the ultrasound-guided subacromial bursal steroid injection. Materials and Methods: Sixty-six shoulders of sixty-two patients with shoulder impingement syndrome treated from March, 2006 to April, 2009 were involved in this study. All cases underwent standardized, nonoperative treatment protocol consisting of 5~12 MHz high resolution ultrasound-guided local steroid injection into the subacromial bursa in modified Crass position. The shoulder range of motion, VAS score and impingement signs were evaluated during the initial and 1year visits. After injection, shoulder elevation exercise was encouraged. Statistical analysis with ANOVA model and Tukey's post-hoc test with the significance level at 5% were performed using SAS program. Results: All cases showed improved range of motion without limitation of shoulder function at immediate post-injection, 6-week, 3-month and 1year visits. The average VAS score at one year follow-up decreased to 2.85 from 6.47 before injection. In all cases the impingement signs became negative immediate after injection. However, 6 cases showed positive impingement signs after 6-week, which became negative after reinjection. The range of motion and VAS score were improved at one-year follow-up compared to initial visit (p<0.0001). No complication was noted at all follow-up period. Conclusion: Ultrasound-guided subacromial steroid injection alleviated the need of surgery, because it was successful in all our cases to improve pain and function of the shoulders until one year follow-up period.

Data obtained for sensory evaluation have a wide dispersion and fuzziness since human sensory organs are used as a means of measuring sensation instead of measuring instruments. Such dispersion and fuzziness are caused by all kinds of time error and have a great influence on the sensory evaluation, but most of previous papers not consider time errors. In this study, the comparative judgement capability of the evaluator was discriminated by means of the eigen- structure analysis on the premise that evaluation values of sensory evaluators obtained by a paired-comparison become different by the order of sample presentation.

Purpose: To investigate MRI findings of the repaired anterior cruciate ligament (ACL). Materials and Methods: Seventeen of arthroscopic ACL primary repair with sutures pull-out technique were followed for 21.4 months (range: 12 to 60 months). Stability was assessed with physical examination and KT-1000 arthrometer (MED metric, San Diego, CA) and postoperative MRI checked with time. The patients were divided into 2 groups according to the location of tear which was defined with the location of remained synovial sleeve. Group I (11 patients) comprised that the tear was located within proximal 1/3 of ACL substance and group II (6 patients) comprised below proximal 1/3. MRI findings of the repaired ACL were evaluated by its course, sharpness, thickness and signal intensity using 3 grade system and correlated with its location of tear. Results: In all cases, Lachman test and flexion-rotation drawer test were negative, pivot-shift test was less than grade 1 and the mean side-to-side difference by use of KT-1000 arthrometer was 1.4 mm (range: -1.0 to 2.5 mm). The overall continuity of the repaired ACL was well maintained in all cases. However, mild sagging was observed in 10 cases(58.8%), mild obscure contour in 6 cases (35.3%), increased thickness in 8 cases (47.1%) and slight increased signal intensity in 5 cases (29.5%). There was no statistical significance in all parameters between 2 groups. And a focal defect at the femoral attachment site in sagittal image was observed in 7 cases (41.2%) of all patients which comprised 2 cases (18.2%) of group I and 5 cases (83.3%) of group II. It was observed more frequently in group II with statistical significance (p=0.035). Conclusion: Some abnormal MRI findings such as mild sagged course, obscure contour, increased thickness and signal intensity, the focal defect at femoral attachment site could be observed even though the stability was well maintained clinically. We thought that the focal defect was affected by the location of tear of ACL.

Background : Circulating cell-free nucleic acids are known to be a noninvasive diagnostic tool for cancer detection. Heterogeneous nuclear ribonucleoprotein (hnRNP) B1, a nuclear core complex, is overexpressed in early stage lung cancer. We intended to evaluate the usefulness of plasma hn-RNP B1 mRNA in differentiating non-small cell lung cancer (NSCLC) from other benign lung diseases, especially pulmonary tuberculosis, which is highly prevalent in Korea and often difficult to distinguish from lung cancer. Methods : Plasma RNA was extracted from 30 patients with NSCLC, 30 patients with benign lung diseases including pulmonary tuberculosis, and 10 healthy controls. Plasma hnRNP B1 mRNA was measured by TaqMan Gene Expression Assay (Applied Biosystems, USA), and pre-developed betaactin (ACTB) mRNA was used for normalization. We analyzed the relative gene expression data using the delta-delta Ct method. Results : Plasma hnRPN B1 mRNA was measurable in 93.3% (28/30) of NSCLC patients. Normalized 2-ΔΔCt of plasma hnRPN B1 mRNA was 62.2 (95%Cl, 6.4-210.1) in NSCLC patients and 2.7 (95% Cl, 0.5-13.6) in benign lung disease patients (P<0.001, Mann-Whitney U test). Conclusions : Plasma hnRNP B1 mRNA was significantly increased in patients with lung cancer compared with that in patients with other benign lung diseases. Plasma hnRNP B1 mRNA may be useful as a potential marker for the detection of NSCLC. 배경 : 혈장에서 검출되는 핵산(cell-free nucleic acids)이 최근 암의 진단에 있어 비침습적 표지자로 유용한 것으로 알려져 있다. Nuclear core complex의 하나인, heterogeneous nuclear ribonucleoprotein (hnRNP) B1은 폐암 초기에 과발 현 되는 것으로 알려져 있다. 본 연구에서는 한국에서 유병률이 높고, 종종 폐암과 구별이 어려운 폐결핵을 포함한 양성폐질환 으로부터 비소세포 폐암환자를 확인하는데 혈장 hnRNP B1 mRNA가 유용한지 알아보고자 하였다 방법 : 비소세포 폐암환자 30명, 폐결핵을 포함한 양성 폐질 환자 30명, 정상인 10명을 대상으로 혈장에서 RNA를 추출하였 다. 혈장hnRNP B1 mRNA를 측정하기 위해 predesigned, validated TaqMan Gene Expression Assay (Applied Biosystems, USA)를 이용하였고, 상대적인 정량을 위해 pre-developed beta-actin (ACTB) mRNA을 사용하였다. Delta-delta Ct 방법을 이용하여 상대적으로 정량하였다. 결과 : 비소세포 폐암환자 93.3% (28/30)에서 혈장 hnRNP B1 mRNA가 측정되었다. 정상인의 hnRNP B1 mRNA로 보정 한 상대 발현 값인 2-ΔΔCt는 비소세포 폐암환자군에서 62.2 (95% 신뢰구간; 6.4-210.1), 양성폐질환자군에서 2.7 (95% 신뢰구간; 0.5-13.6)로 통계적으로 유의하게 높게 발현되었다(P<0.001, Mann-Whitney U test). 결론 : 혈장 hnRNP B1 mRNA는 정상대조군 또는 양성폐질 환군에 비해 비소세포 폐암환자에서 유의하게 증가되어 있었다. 따라서, 혈장 hnRNP B1 mRNA는 암표지자로서 비소세포성 폐암의 검출에 유용할 수 있을 것으로 판단된다.

Purpose: To analyze the clinical outcome after ultrasound guided multiple dry needlings and local steroid injection for acute calcific tendinitis of shoulder. Materials and Methods: Twenty patients with acute episode of pain by calcific tendinitis of shoulder with average age 58.2 (50~70 years) and follow-up of 18 months in average (range, 12~24) were included in study. There were 18 patients with right and 2 with left sided involvement. All patients had calcific deposits in the supraspinatus tendon. All patients underwent standardized nonoperative treatment protocol, consisting of 5~12 MHz high resolution ultrasound guided multiple dry needlings with 18 guage needle, followed by 2% lidocaine 1cc and 40 mg/ml depomedrol 1cc injection at site of calcific tendinitis. The outcome was assessed by UCLA shoulder score, range of motion and VAS score. A statistical analysis with ANOVA and Tukey's post-hoc test with the significance level at 5% was performed using SAS 9.1 software (SAS Institute, Cary, NC). Results: All patients got continuous relief of pain right after the procedures until final follow-up. Before the procedures, the UCLA scores were fair in 15 patients and poor in 5. After the procedures, the UCLA scores were excellent in 16 patients and good in 4. All cases revealed no limitation of shoulder function. The average VAS score decreased from 8.9 before the procedures to 0.5 at final follow-up (p<0.0001). No complication was encountered. Conclusion: An ultrasound guided local steroid injections following multiple dry needlings would be one of the useful treatment modality for the acute calcific tendinitis of shoulder.

전방십자인대의 일차수복술이나 재건술후에 장기간의 비체중부하가 필요한지를 결정하기 위해서 일차수복술을 시행한 96례와 재건술을 시행한 82례등 총 178례를 대상으로 술후 체중부하시기에따라 두군으로 나누어 비교분석 하였다. 모든 례에서 술후 보조기를 착용하였고 120례에서는 술후 첫6주간 점차적으로 관절운동범위를 증가를 시키고 다음 6주간은 완전운동범위 회복상태에서 유지후 술후 12주에 체중부하를 허용하였으며 나머지 58례에서 술후 완전신전상태에서 즉시 체중부하를 시켜서 정기적으로 Lachman검사, KT 2000을 이용하여 불안정성여부를 관찰하였다. 평균 추시기간은 4.2년(2년$\~$6년)이었고 불안정성에 대한 평가는 AMA 분류에 따랐다. 최종추시상 모든환자에서 1+이상의 불안정성은 발견되지 않았으며 술후 12주에 체중부하를 한군에서 1a+가 104례$(86.7\%)$, 1b+군이 16례$(13.3\%)$로 관찰되고 즉시 체중부하를 한 군에서 1a+가 51례$(87.9\%)$, 1b+가 7례$(12.1\%)$에서 보였으나 통계적으로 의미있는 차이는 없었다(P>0.05). 본연구의 결과로 전방십자인대 일차수복술이나 재건술후 신전보조기를 착용시키고 즉시 보행을 시키는 것이 술후 슬관절의 불안정성에 영향을 주지 않으며 안전한 재활방법으로 생각된다.

호텔 종사원의 직무만족요인에 관한 실증 연구 -서울지역 특1급 호텔을 중심으로-

김정만 한국관광식음료학회 1998 관광식음료경영연구 Vol.9 No.1

In the 21st century the service industry, particularly the hospitality industry, has the potential to develop into its golden age. In preparation for this hotels must maximize management proficiency by introducing reasonable and scientific systems into their current operations. The hotel industry takes it for granted that it can meet the final business goal by way of effective management of human resources. However, comprehensive papers on the subject of employee satisfaction have not appeared or been presented in Korean business studies. And although papers from abroad have touched on the subject they are not focused on the specialized domain of human resources as it applies to the comprehensive matters relating to job satisfaction as a corelationship to business success. This study focuses on some problems that must be overcome in achieving business objectives while striving at the same time to maintain satisfaction. The purpose of this study is to find the factors that measure employee job satisfaction in the hotel industry. To establish the purpose I reviewed the definition of the job satisfaction. An antecedent study of job satisfaction and Questionnaires were used to acquire data, specifically, hotel employees were selected randomly from the six super-deluxe hotels in Seoul to respond to thorough questionnaires. As a result of the study on the variables of Sex, Position, Length of Service, Opportunity for Promotion, Working Conditions, Wages and Hotel Situation. As a whole, promotional opportunity, wages and working conditions were frequently cited as negative factors in the responses. A comprehensive approach that includes improving wages and that reflects management's sincere concern with the working conditions of the employees is urgently needed. Hotel management that is willing to examine employee satisfaction periodically and provide proper solutions can prevent dissatisfied employees from separating from their jobs. This study has some limitation in that it is restricted geographically and in research method. That is, only six super-deluxe hotels in Seoul were selected as the subject of study and only the questionnaire method of obtaining data was used out of various available research methods.
