The main objective oh this paper is to perform an empirical analysis on the relationship between various marketing activities and financial performance of Korean hospitals. A survey was conducted through structured questionnaire for 495 hospitals, and data from 218 hospitals were utilized in the final analysis. (response rate : 44%) Survey items include general characteristics of the hospitals (size, type, location), degree of competition, financial performance, marketing organization/ budget, and level of various marketing activities in service development, access improvement, promotion, and pricing. We examine descriptive statistics of the response scores on marketing activities to evaluate the current status of marketing management of Korean hospitals, compare the results across hospital size, type and location, and perform regression analysis to investigate the relationship between marketing and financial performance. Major findings are as follows : 1) About 46% of the responding hospitals gave marketing departments although they are named as 'planning' or 'PR' departments, and the marketing budget on average represents 1.74% of the total expenditures. 2) Average level of marketing activities is calculated to be about 3.32 on 5-point scale, meaning that Korean hospitals implement their marketing programs 'somewhat actively'; however, the scores on the areas of marketing planning and strategy are relatively low. 3) Large hospitals tend to be more active in marketing than small hospitals, and public hospitals' activities in marketing are not lower compared to private hospitals. 4) Level of overall marketing activities is positively related with financial performance measured by various financial indicators except for profitability, implying that marketing is successful in revenue generation but needs to be more cost-effective. Also, when the marketing variables are separately included in the regression, no significant relationship is found, which means that various marketing activities are more effective when they are collectively implemented.

As the educating activities for pre-school children are recently getting increased utilizing various language educating program sheets in child edu-cating organizations or private home, this study was conducted to investigate the language educating contents being taught in the sheets and to analyze some problems of the sheets. As a first step of the study I surveyed 30 parents of children aged 4 to 5 in order to select proper program sheets which are widely used for children. From the above survey total 3 home sheets are selected arbitrarily for this investigation. As a result, most sheets have made children read the contents separating the syllables or words in reading emphasizing part, instead of making them read the contents as a whole sentence or story. In writing educating field also, it was emphasized to dictate the syllables or words just after listening to or watching them, not to the recognition of overall sentence. Also in speaking area which was low in weight as educating contents, there was a problem of repeating the names of simply suggested pictures, not inducting children to express their own thinking or feeling regarding educating contents. Even in listening field, it was not desirable to train children listen to the contents for the dictating purpose only, not helping them to understand the global flow of story.

단순상한 및 확장된 일반상한제약을 갖는 선형배낭문제의 O(n^2log n) 해법

원중연 한국경영과학회 1997 한국경영과학회지 Vol.22 No.3

We present an extension of the well-known generalized upper bound(GUB) constraint and consider a linear knapsack problem with both the extended GUB constraints and the simple upper bound(SUB) constraints. An efficient algorithm of order O(n^2log n0 is developed by exploiting structural properties and applying binary search to ordered solution sets, where n is the total number variables. A numerical example is presented.

Object : This study was performed to increase the sensitivity and specificity for screening the examinee of second hearing test. Methods : Study subjects were 219 workers who exposed more than average 80dB. They were taken the hearing test two times, before noose exposure and at 1 hour to 4 hours after worksite noise exposure. To investigate the ambient noise workers who were taken the hearing test in the test room which ambient noise was less than 45dB were classified Group I and the others were classified Group II . To calculate the sensitivity and specificity we made it gold standard whether worker had noise induced hearing loss. Results : Difference of hearing loss between before and after noise exposure for left and right ear was 11.4 dB and 11.7 dB respectively at 500 Hz, 8.7 dB and 9.6 dB at 1,000 Hz, 6.3 dB and 6.9 dB at 2,000 Hz and 6.9 dB and 7.4 dB at 4,000 Hz In Group I. That for left ear and right ear was 5.8 dB and 4.9 dB at 500 Hz respectively, 5.4 dB and 6.4 dB at 1,000 Hz, 6.3 dB and 5.3 dB at 2,000 Hz, and 5.5 dB and 5.8 dB at 4,000 Hz in Group II. The sensitivity was 100 in both Groups and the specificity was increased to 58.3 and 71.8 in Group I and Group II respectively until 10 dB was deducted from hearing level at 1,000 Hz and 4,000 Hz. Conclusion : When the screening hearing test was performed at worksite, we might deduct 10 dB from measured hearing level to increase the specificity without reduction of sensitivity.

Abstract : The response characteristics of long continuous sensors are studied for damage detection in a plate structure based on strain waves that are generated by damage. That is, the response characteristics of the long continuous sensors, which are long ribbon-like sensors and can be fabricatedby piezoceramic ribbon fibers, etc. are studied by simulation of wavepropagation in a panel to improve sensing capability of the waves that arepropagating by damage. The advantage of the long continuous sensor is toimprove damage detection by having a large coverage of sensors on thestructure using a small number of channels of data acquisition. Theresponses from the long continuous sensor are similar if the damages arelocated at the same normal distance to the sensor, and these similar patternscan make it easy to estimate the damage. Keywords : long continuous sensor, damage detection, wave propagation 요지 : 이 연구에서는 손상에 의해 발생하는 변형률 웨이브 검출을 통한 판 구조물의 손상위치추정을 위하여 연속형 센서의 응답특성에 대하여 연구하였다. 즉, 균열발생 및 균열진전등과 같은 손상에 의하여 발생되는 웨이브를 보다 효과적으로 감지하기 위하여, 피에조 세라믹 섬유 등을 이용하여 리본 형으로 길게 제작할 수 있는 연속형 센서의 응답특성을 웨이브 전파 시뮬레이션을 통하여 연구하였다. 이러한 센서를 적용하는 경우, 적은 수의 데이터 취득 채널을 이용하여 구조물의 넓은 영역을 감지할 수 있는 장점이 있다. 또한 연속형 센서와 여러 손상위치들의 직각거리가 같은 경우 센서에서 감지되는 각각의 응답들은손상위치들에 대해 거의 동일한 양상을 보이며, 이러한 응답패턴을 이용하면 판 구조물의손상위치를 더욱 효과적으로 추정할 수 있을 것으로 판단된다. 핵심용어: 연속형 센서, 손상추정, 웨이브 전파

전두사골 수막뇌류 및 Saethre-Chotzen증후군에 의한 안와격리증의 치험

송중원,한기환,박성근,강진성 大韓成形外科學會 1991 Archives of Plastic Surgery Vol.18 No.2

본 교실에서는 전두사골 수막뇌류에 의한 안와격리증 2례는 두개내 접근으로 수막뇌류 절제술을 실시함과 동시에 두 개외 접근으로 안와내벽 및 외벽 절골술로써 교정하였으며 Saethre-Chotzen 후군에 의한 1례는 두개골 성형술과 U형 절골술로 교정하여 비교적 만족할 만한 결과를 얻을 수 있었기에 보고하는 바이다. The authors experienced two cases of mild hypertelorism with frontoethmoidal meningoencephalocele and one with Saethre-Chotzen syndrome. The first and second cases, which had nasofrontal and nasoethmoidal meningoencephalocele respectively, were corrected by resection of the meningoencephalocele, repair of the dura, and calvarial bone graft intracranially, and combined medial and lateral orbital wall osteotomy with augmentation rhinoplasty with calvarial bone grafts extracranially. To stabilize the orbital contents medially, a split osteotomy of the lateral orbital wall and interpositional bone graft were done in order to avoid step deformity of the lateral orbital rim. The third case, Saethre-Chotzen syndrome characterized brachycephaly, hypertelorism, ptosis of the eye lid, maxillary hypoplasia, lower set frontral hair line, and partial cutaneous syndactyly was corrected by a Modified Marchac technique for remodelling the forehead and a subcranial U-osteotomy for mild hypertelorism. Maxillary hypoplasia was corrected effectively by advancement on the medial portion of the U-shaped bony segment. Augmentaton rhinoplasty with calvarial bone graft and chip bone grafts on the anterior nasal spine was done simultaneously. A large amount of nasal bone grafts in two cases were absorbed, and then augmentation rhinoplasty using silicone implant was performed after 6 months, 12 months respectively. In mild hypertelorism with associated deformity, a extranial osteotomy with augmentation rhinoplasty and correction of associated deformities can offer good aesthetic results.

Thyroglossal duct cyst is the most common developmental anomaly of the thyroid and the second most common pathology among childhood cervical masses. They present non-tender palpable mass on midline neck, and they are usually asymptomatic. The cysts are usually benign, but one percent of cases is associated with malignancy. From the world literature, 115 cases of malignant thyroglossal duct cyst are available for review. Despite aspiration cytology and the radiologic images, malignant thyroglossal duct cysts are usually comfirmed after surgery. The authors experienced a case of papillary carcinoma arising from the thryroglossal duct cyst without evidence of local invasion.
