Purpose: The objective of our study was to figure out costs of nursing services in general nursing units based on the PCS in order to determine an appropriate nursing fee schedule. Method: The data were collected from 8 hospitals from September 9 to October 8, 2002. The costs of nursing services in general nursing units was analyzed by nursing hours based on the nursing intensity. The inpatient in the general nursing units were classified by Park's PCS tool(2000). Results: The distribution of patients by PCS ranged from class I to Class III in general nursing units. The higher PCS in general nursing units consumed more nursing hours. As a result, the higher nursing intensity, the more the daily average nursing costs in general nursing units. Conclusion: We found that the higher PCS, the more the daily average nursing costs in general nursing units. In conclusion, our study provides the evidence to refine the current nursing fee schedule that it does not differentiated from the volume of nursing services based on the nursing hours.

The prevalence of obesity and its related factors in adolescent girls in Seoul area were investigated from April, 18 to June, 29 1985 bymeans of anthropometry, dietary intakes and general environmental factors. Nine hundred and sixty junior high school girls were selected and invterviewed for 24-hour food intakes. Weight, height, a 우 skinfold thickness(triceps, abdominal) were measured and information on the general backgroun of the subjects were obtained by questinnaire. Subjects were divided into six groups according to their relative weights. It was observed that majority of the parents were under fifty years old and had high school education . In general, father was older and higher in educational levels than mother. Two thirds of subjects lived in their own houses and had three to four siblings. AVerage weight and height of subjects were 46.0kg and 154.4cm, which were higher than Korean natianl average. Average relative weight was 29.75 and average Kaup index was 1.925. Skinfold thickness was 13.4mm fo rtricepts and 16.4mm for abdominal . Prevalence of obesity was 12.9% and 4.8% by criteria of relative weight and skinfold thickness. Average intakes of most of nutrients except iron were acceptable but about one third of the subjects had less than 2/3 of RDa for calcium, iron, vitamin A, and riboflavin. As a whole, prevalence of obesity in this study was higher than those observed in the past surveys. Relationship of dietary intakes and general environmental factors that seemed to influence the obesity were integrated as such. As parents educational levels were higher, it tended to be higher in living standard and have fewer family members and siblings. These may influence more nutrient intakes so that fatness of the subjects seemed to be greater. In the meantime, parents fatness was closely related to those of children indicating an involvement of genetic factors. And also, food habits of individuals such as frequency of snack and bedtime snack were related to fatness significantly.

This study performed the quantitative distribution analysis of created voids to an insulator when applying general flame and DC short-circuit current to 2.5 $mm^2$ HIV (600 V Grade Heat-Resistant Polyvinyl Chloride Insulated Wires). The diameter of cross-section of HIV normal product and the radius of conductor were measured to be 3.3 mm and 1.8 mm. The exterior of HIV exposed to general flame showed severe carbonization and its interior exhibited voids created by dechlorination reaction. This study observed the characteristics that, when the shortcircuit current applied for 2 seconds from a DC 12 V lead battery, the conductor and neighboring insulator were melted, causing the insulator adhering to the conductor. On average, 87 voids were created on 10 mm of the HIV. The average diameter of voids was 0.25 mm. In addition, it was found that, when the short-circuit current applied for 4 seconds, the interior of insulator in contact with conductor severely carbonized and showed exfoliation phenomenon. On average, 47 voids were created, with more voids at the bottom. The average diameter of voids was 0.20 mm. When the short-circuit current for 6 seconds, most parts of upper part of conductor was carbonized, 20 voids were created. The average diameter of voids was measured to be 0.24 mm. It could be seen that the created voids received little influence by the type of energy source and the number of created voids was reduced as the energy supply time increased.

This study has attempted to collect actual spot's opinions and analyze importance-performance of indicators for the evaluation of hospital nutrition department. The results of this research were as follows: first, the average score of self-estimated performance was 3.75 based on a 5-point scale. The degrees of importance of hospital foodservice and nutrition department management were in the range of 3.71~4.85 out of 5.0 and the mean importance degree score was 4.37. Second, the average score of self-estimated performance in each category was significantly higher in the case of general special hospital compared to general hospital. Especially average performance score of nutrition management in the general special hospital was higher than that of general hospital (P<0.001). The average performance score of the hospital with more beds was significantly higher than that with less beds. Contract managed hospital's score was significantly higher than that of self-operated hospital in two categories, "facilities management" and "nutrition management" (P<0.05, P<0.01). In foodservice and nutrition management of task-separated hospitals, the average performance scores were significantly higher than those of not-separated hospitals (P<0.01, P<0.001). Third, according to the importance-performance analysis of recognition about indicators for the hospital nutrition department's operations evaluation, 'foodservice facilities management' and 'foodservice sanitation management' were in 'doing great', 'nutritional management' and 'operational management' were in 'low priority', and 'other foodservice management' was in 'overdone'. In conclusion, there's a need for institutional specific standards of sanitation for Korean hospital foodservice.

Objective : This study is to evaluate the efficacy of dorsal short-segment fixation in unstable thoracolumbar junction fractures. Methods : The cases of 20 patients who underwent dorsal short-segment fixation were reviewed retrospectively. Clinical outcomes were analysed using Sonntag's pain level, work status, and neurological scale according to the modified Frankel classification. Radiological outcomes were analysed using Mumford's anterior body compression[%], canal compromise ratio, and Cobb's kyphotic angle. Results : At the latest clinical follow-up [average=14.6 months]. there were 19 [95.0%] in group I and 1 patient [5.0%] in II in pain level. The postoperative work status were 17 [85.0%] in group I, 2 patients [10.0%] in II, and 1 patient [5.0%] in V. Surgery brought to improve the neurologic status. In success group [19 cases, 95%], the average canal compromise ratio was reduced from 0.57 [${\pm}0.07$] to 0.05 [${\pm}0.08$] [P<005], the average anterior body compression [%] was reduced from 41% [${\pm}17$] to 18% [${\pm}14$] [P<0.05], and the average preoperative kyphotic angle was $20.0^{\circ}$ [${\pm}9.0$], and corrected to $5.7^{\circ}$ [${\pm}7.1$] postoperatively, and progressed to $7.8^{\circ}$ [${\pm}6.2$] at the latest follow-up. There was a case of implantation failure in an elderly osteoporotic patient. Conclusion : Although there are limitations in the patient number and follow-up period, the present study favors dorsal short-segment fixation for selective cases in unstable thoracolumbar junction fractures.

Purpose: To evaluate and analyze the incidence, clinical features, cause and surgical outcomes of iatrogenic hallux varus deformity after hallux valgus surgery. Materials and Methods: Twenty-six Hallux varus deformities after hallux valgus surgery were evaluated. Clinical tolerability, patient's satisfaction and the main causative factor for varus deformity were evaluated. Radiologically, we measured the 1st intermetatarsal angle and hallux valgus angle on pre- & postoperatively. Results: 10 cases of 26 varus deformities were clinically intolerable. The patients complaint of mainly cosmetic and shoe fitting problems rather than pain and the main cause of deformities were over-correction of 1 st intermetatarsal angle. Radiologically, the average 1st intermetatarsal angle was 2.4 degrees and the hallux valgus angle was -9.2 degrees. After varus correction surgery, the average follow up were 17 months and the average 1st intermetatarsal angle was 2.3 degrees and the hallux valgus angle was 2.7 degrees. The average score of AOFAS Hallux Metatarsophalangeal -Interphalangeal Scale was 91 points. Conclusion: The hallux varus deformity after hallux valgus surgery came from mainly overcorrection of 1 st intermetatarsal angle. The management composed of just observation, tendon transfer and fusion, and each method could get satifactory results with appropriate indication.

In this study, the state-space Newmark method based on average velocity is presented to analyse the transient dynamic response for general dynamic system. The conventional Newmark method based on average acceleration cannot he directly to the first-order state-space differential equations introducing the state-space vector. To overcome this problem, the time-step integration algorithm, based on average velocity concept, suitable for the first-order state-space differential equations is proposed In results, the proposed method has %he numerical stability and order of accuracy, which is proved analytically, equal to those of the conventional Newmark method based on average acceleration. Also, the formulation for numerical solution is very simple and the calculation time Is nearly equal to that of the conventional Newmark method based on average acceleration in spite of an increase of two times over matrix size. This method will be look forward to applying the general dynamic system to calculate the transient dynamic response.

An implicit direct-time integration method for obtaining transient responses of general dynamic systems is described. The conventional Newmark method cannot be directly applied to state-space first-order differential equations, which contain no explicit acceleration terms. The method proposed here is the state-space Newmark method that incorporates the average velocity concept, and can be applied to an analysis of general dynamic systems that are expressed by state-space first-order differential equations. It is also readily coded into a program. Stability and accuracy analyses indicate that the method is numerically unconditionally stable like the conventional Newmark method, and has a period error of 2nd-order accuracy for small damping and 4th-order for large damping and an amplitude error of 2nd-order, regardless of damping. In addition, its utility and validity are confirmed by two application examples. The results suggest that the proposed state-space Newmark method based on average velocity be generally applied to the analysis of transient responses of general dynamic systems with a high degree of reliability with respect to stability and accuracy.

The adoption of the YAR 2016 brings to an end the 12 years of uncertainty for shipowners and Marine insurers which followed the adoption of the YAR 2004, which did not have the support of shipowners, and which were very rarely used in preference to the well-established and well understood YAR 1994. The development and finalisation of the YAR 2016 is the product of an extensive review undertaken by the IWG with input from the International Group, international average adjusting community, National Maritime Law Associations, the International Chamber of Shipping, BIMCO and IUMI amongst others. The Group clubs welcome and support the adoption of the YAR 2016 and recommend its incorporation in members' future shipping contracts. The Club will be taking steps to adopt logical changes to the 2017 Rules. In the meantime, this circular serves as confirmation Club cover extends to all shipping contracts incorporating YAR 2016. This study analyse the adjustment practice of general average according to the application of YAR 2016.
