This paper presents mathematical models of a preventive replacement for a product under warranty. The hybrid warranty policy and a periodic replacement policy with minimal repair at failure under warranty are considered in this paper. All repair and replacement costs in a replacement cycle are converted into the present worth using a continuous discount rate and then the pesent worth is converted into the average funds flow using the funds-flow capital-recovery factor. The purpose of this problem is to find the optimal preventive replacement time for a consumer product under warranty so as to minimize the average cost funds flow. A numerical example is presented.

孫銀一 진주여자전문대학 1995 論文集 Vol.18 No.-

This study presents mathematical models of warranty cost analysis for a product under warranty. Estimation of warranty costs is one of the most important problem facing manufacturing today. On the manufacturer's point of view, exact estimation of warranty costs helps the decisions on budgeting, product pricing, and A/S capacity planning, etc. The free warranty policy is considered in this paper. The manufacturer's warranty costs for a product with two types of failures, repairable or irreparable, are calculated under warranty policy. In this paper, it is assumed that the lifetime distribution is a Exponetial, and warranty period is renewed for replacements due to warranty contract.

The posterior fossa surgery(PFS) via lateral suboccipital craniectomy(SOCE) and partial mastoidectomy always has the potential cerebrospinal fluid(CSF) leakage and painful deformity in the suboccipital and retroauricular area. This study describes the efficacy of our mathods for dural closure and cranioplasty to prevent CSF leakage and suboccipital depression respectively after posterior fossa exploration using retrosigmoid suboccipital approaches. This techniques were performed in the consecutive 10 patients who underwent PFS in a park-bench position for different types of lesions. The SOCE and driling of the mastoid process were done minimally. Following intradural works, dura was closed in a watertight manner usually using a graft, thereafter reinforced with GelfoamR and biological human allogenic fibrin glue (GreenplastR). After augmentation of dural suture, opened mastoid air cells were bone-waxed and covered with fat graft by anchoring sutures. For the reconstructive cranioplasty, autologous bone chips and dust obtained at craniectomy were wrapped with SurgicelR. Then it was replaced to the site of suboccipital bone defect and GreenplastR was applied on and around the bone plate. The age of patients ranged from 33 to 61 years. Five cases of hemifacial spasm have been undertaken decompression of the facial nerve and four cases of cerebellopontine angle masses(meningioma, epidermoid, arachnoid cyst, and cerebellar metastasis) were treated by retrosigmoid approach. Computed tomography and plain cranial films taken a few month later showed successful and good appearance of the suboccipital and retromastoid area. All patients made a excellent recovery without any postoperative complications. Preliminary results of up to 10 months show no CSF leakage nor a persistent headache. There was no adverse reactions related to fibrin glue. We think that the present technique is a valuable method to minimize or avoid postoperative CSF leakage and to restore an autologous bone plate in a cranial defect by piecemal craniectomy.

孫銀一 진주여자전문대학 1996 論文集 Vol.19 No.-

A wrranty is a contractual obligation incurred by a manufacturer in connection with the sale of a product. Under warranty service contract, the manufacturer agrees to repair and maintain the product over warranty period for a fee payment by the consumer. Recently, many companies have increased the warranty period for their products to capture more customer. In this paper, We briefly reviewed and classified previous studies on warranty policies. Also, We give a broad introduction to the subject of warranty and a brief outline the scope of the warranty study. This study offers an effective methodology for studying the warranty study. The objective of this study is to develop a framwork for the analytical study of warranty issues related to warranty and of importance to manufacturers and consumers. Also, The importance of warranty to both manufacturer and consumer are discussed. This paper will deal with the modeling and analysis of a variety of warranty policies. This study is one of many guidlines that need to be developed to study warranty in its broadest context.

오은숙,강무일,이원영,오기원,임동준,이소영,이정민,고승현,김성래,안유배,손현식,윤건호,차봉연,이광우,손호영,강성구 대한당뇨병학회 2000 임상당뇨병 Vol.1 No.1

연구배경: 감염질환은 혈관질환과 함께 당뇨병의 중요한 사망원인의 하나이며, 혈당조절이 불량할수록 감염 빈도가 증가됨은 잘 알려져 있다. 간농양의 발생이 있어서도 당뇨병은 중요한 기저질환 중의 하나이다. 일반적으로 간농양의 가장 흔한 원인균은 Escherichi coli라고 알려져 있으나, 최근 당뇨병을 가진 간농양 환자에서 Klesiella pneumoniae의 검출이 증가되고 있다. 또 최근 연구에 의하면 K.pneumonie가 간농양의 가장 흔한 원인균이며, K. pneumoniae에 의한 간농양은 K.pneumoniae 이외의 균주에 의한 간농양보다 당뇨병과 밀접히 관련되어 있다고 보고된 바 있다. 이에 저자들은 간농양 환자를 대상으로 당뇨병환자의 빈도를 알아보고, 그 원인균 및 특징을 비당뇨병 환자들의 경우와 비교해 보고자 하였다. 방법: 1992년 1월부터 1999년 6월까지 방사선학적 검사 혹은 수술에 의해 간농양이 확인되거나, 경피적 천자나 수술을 통한 배농액 배양, 혹은 혈액 검사에서 원인균이 증명된 182명의 환자를 대상으로 후향적 임상고찰을 실시하였다. 결과: 화농성 농양을 가진 167명의 환자(남:94명, 여:73명)중 당뇨병을 가진 환자는 54명 (남:30명, 여:24명)으로 32.3%를 차지하였다. 환자의 평균나이는 당뇨군에서 62.1 ± 13.4세, 비당뇨군에서는 55.1 ±15.5세로 당뇨군에서 높았으며(p=0.0021), 남녀간의 평균나이 비교 시 두 군 모두 여성의 나이가 의미있게 높았다. 비당뇨군에 비하여 당뇨군의 경우 저알부민혈증의 빈도와 aspartate transaminase가 증가되어있었다. 원인균주는 K. pneumoniae (당뇨군54%, 비당뇨군 39.1%), E. coli(당뇨군 17.5%, 비당뇨군 18.8%), Pseudomonas aeruginosa, Streptococcus viridans, Enterococcus 순이었으며 두 군간의 의미는 차이는 없었으나 K. pneumoniae의 경우 다른 균종에 비해 단독감염의 빈도가 높았다(82.8%). 사망률은 당뇨군에서 16.7%, 비당뇨군에서 7.1%로 당뇨군에서 의미있게 높았으며(p=0.019), 당뇨군에서의 사망환자는 모두 패혈증이 동반되어 있었다. 당뇨환자의 사망군은 생존군에 비해 당뇨병 이환기간이 길고 혼합감염의 빈도가 높았다(p=0.046). 검사실 소견에서는 총 빌리루빈 및 알카리성 포스파타제의 증가가 관찰되어 있었다. 결론: E. coli가 간농양의 주된 원인균이라는 기존 보고와는 달리 당뇨군과 비당뇨군 모두 K. pneumoniae가 간농양의 주된 원인균이었다. 또한 당뇨 유병기간이 길고 당뇨조절이 불량한 환자에서 혼합감염이며 총 빌리루빈 및 알카리성 포스파타제의 증가등과 같은 위험인자가 존재할 경우 사망률이 증가될 수 있으므로 이들 군에서는 적극적인 치료가 필요할 것으로 사료된다. Background: Liver abscesses are commonly associated with underlying disease, particularly diabete mellitus. The number of the liver abscesses caused by Klebslella pneumoniae in diabetic patient has been increased in Korea nowadays. This study was conducted to clarify the clinical presentation and prognostic factors of pyogenic liver abscesses, especially in diabetic patients and to determine the proportion of K. pneunomiae as a pathogen in liver abscess in Korea. Methods: Medical records of 167 patients treated for pyogenic liver abscess from January, 1992 through June, 1999 were reviewed retrospectively in detail. Major Pathogenic organism, clinical manifestations, prognostic factors, the importance of diabetes mellilus as an underlying disease and its effect on clinical features and prognosis were analyzed. Results: Among 167 cases of pyogenic liver abscess, underlying diabetes mellitus was present in 32.3%. The mean age of patients was 62.7 13.4 years in diabetic liver abscess group and 55.1 15.5 years in non-diabetic liver abscess group. Most liver abscesses were cryptogenic in origin or secondary to the billary tree diseases. The clinical presentations among the two groups were not significantly different. When compared to patients without diabetes, patients with diabetes had significantly higher proportions of hypoalbuminemia and elevated aspartate transaminase level. The most common organism of the pyogenic abscess was K. pneumoniae in both groups. Percutaneous drainage of the abscess with appropriate antibiotics was the most commonly used therapeutic modality in liver abscess. The mortality rate of diabetic liver abscess is 16.1 % and 7.1% in nondiabetic liver abscess. Complications, especially septicemla, were found more frequently in patients with diabetes than in patients without diabetes (64.8% vs 28.3%, septicemia : 31.5% vs 9.7%). The factors influencing mortality in the diabetic liver abscess were disease duration, mixed infection, presence of septicemia, elevated bilirubin and alkaline phosphatase. Conclusions: In contrast to prior report that the E. coli was the most common pathogen in liver abscess, we found that K. pneumoniae was the most common organism cultured in liver abscess. Diabetic patients have more complications and higher mortality than patients without diabetes. Early detection and proper treatment are needed to improve the outcome for diabetic patient with liver abscess.

Purpose : The purpose of this study was to investigate relationships among family support, self-care, and quality of life of patients with arthritis through a survey. That will be basic data to plan nursing intervention for promoting quality of life for patients with arthritis. Method : The convenient sample of this study consisted of 120 patients with arthritis and data were collected using questionnaires during August 2006 from two OPDs of rheumatoid centers in C University hospitals. The study instruments were used to measure Self Care (So, 1992), Family Support (Kang, 1984), and Quality of Life (Ro, 1988). The data were analyzed using ANOVA, Duncan test, and Pearson correlation. Result : The mean scores were 3.56 for family support, 4.16 for self-care, and 3.19 for quality of life. The level of self-care was significantly higher in those men, having an occupation, higher income, and living with family members. The level of family support was significantly higher in those men, having an occupation, living with family members, and having a helper. The level of quality of life was significantly higher for those men, having a higher income, and shorter length of illness. Three relationships were found to be positively correlated: 1) between the levels of family support and self-care (r=.53), 2) between the levels of self-care and quality of life (r=.55), and 3) between the levels of family support and quality of life (r=.54). Conclusion: Therefore, a nursing intervention program needs to be developed to promote family support, and self-care for quality of life for patients with arthritis.

This study was to examine the effect of VMD factors on brand identity for SPA brands. As brand stimulus, four SPA brands(e.g., Basic House, Codes combine, Uniqlo, Zara) were selected by pretest. For collecting data, a self-administered questionnaire was developed based on the literatures and intercept survey was conducted. A total 508 usable responses were obtained from consumers who shopped at the selected brands' stores. For data analysis, descriptive statistics, factor analysis, and regression analysis were used. As perceived by consumers, VMD consisted of seven factors: lightening, scent, color, layout, music, window display, and item presentation. The VMD factor was significantly related to brand identity for the SPA brands. Specifically, brand awareness was predicted by color, layout and item presentation; brand association strength was predicted by color, layout, and widow display; favorable brand association was predicted by item presentation; salience of brand association was predicted by color and music; and brand image association was predicted by color, layout, music, and item presentation. Thus, this study discussed a managerial implication for SPA retailers to develop a visual merchandising strategy in the competitive marketplace.

The pimapty sella syndrome results from and extension of the subarachnoid space into and intrasellar position with subsequent remodeling of the sella turcica and flattening of the pituitary gland. We experienced a case of primary emty sella syndrome in a 14-year-old male patient who was hospitalized because of short stature and micropenis. The endocrinologic studies revealed growth hormone and gonadotropin hormone deficiencies. The magnetic resonance imaging showed sella turica filled with CSF and flattened pituitary glad. The patient was followed-up with growth hormone therapy and the result was favorable.
