Purpose: The purpose of this study was to suggest new directions for public health programs in rural and remote areas. Method: For this purpose, a literature review was done including articles, research reports, and master theses and doctoral dissertations. Results: Public health programs in rural remote areas were found to be very insufficient in terms of professional personnel and program diversity. Especially, there is a lack of adequate manpower and infra-structure in the public health sub-centers at the township and sub county level. Although community health practitioners at the village level are providing public health service beyond medical care, their coverage rate is very low. Conclusion: The results suggest a need to strengthen the function of public health sub-centers to provide comprehensive public health service based on the life-cycle approach. For this new change, legal and political support must be developed.

Ten healthy wome 2-~25 years participated in a 5-week metabolic study to investigate the daily riboflavin requirement of Korean women. Three daily menu and meal patterns were used. Low riboflavin(LR) diet provided riboflavin at a level of 0.71mg / 1000Kcal based on food composition table. High riboflavin(HR) diet provided 1.14mg / 1000Kcal. The riboflavin status was assessed by erythrocyte glutathione reductase activity coefficient(EGRAC) and urinary exretion of riboflavin. Mean EGRAC of LR period and HR period were 1.17+0.08 and 1.01+0.03, repectively. There were discrepanices of riboflavin content of experimental diet between chemical analysis and calculation by Korean food composition table. Urinary riboflavin excretion of subjects was acceptable over the whole study period. It appeared that 0.71mg / 1000Kcal is requirement of riboflavin to maintain EGRAC withing normal range. Thus, it is suggested that current recommendation of 0.6mg / 1000Kcal of riboflavin intake may not be adequate as RDA level in Korea.

Spinal subarachnoid hemorrhage (SAH) due to solitary spinal aneurysm is extremely rare. A 45-year-old female patient visited the emergency department with severe headache and back pain. Imaging studies showed cerebral SAH in parietal lobe and spinal SAH in thoracolumbar level. Spinal angiography revealed a small pearl and string-like aneurysm of the Adamkiewicz artery at the T12 level. One month after onset, her back pain aggravated, and follow-up imaging study showed arachnoiditis. Two months after onset, her symptoms improved, and follow-up imaging study showed resolution of SAH. The present case of spinal SAH due to rupture of dissecting aneurysm of the Adamkiewicz artery underwent subsequent spontaneous resolution, indicating that the wait-and-see strategy may provide adequate treatment option.

This study was performed to investigate the effect of dietary magenesium on stress reactions in rats having abdominal surgery. Sixty three male rats of sprague-dawley strain were blocked into 3 groups : rats fed regular magnesium (0.05% Mg: control) rats receiving regular magnesium with surgery(Mg-adeq : S) Five weeks after feeding abdominal surgery was performed and randomly chosen 7 rats from each group were sacrificed on 1, 3 and 5 days after surgery. Te following were found ; 1) Rats fed marginal magnesium showed significantly elevated urinary urea nitrogen urinary potassium and plasma glucose compared controls only one day after abdominal surgery but not 3 days or 5 days after surgery 2) Rats fed adequate magnesium did not show any significant change in metabolic stress indicator after surgery. 3) Plasma free fatty acid and cortisol level were not different among groups. 4) Decreased plasma magnesium and potassium level were found in rats fed marginal magne-sium and sacrificed one day and three days after surgery.

Recently buildings are being constructed on the downtown area. In most building construction sites on the downtown area, the need for adequate material inventories are critical in order to avoid project delays and cost increases due to inappropriate deliveries of key materials. However immoderate material inventories cause increasing inventory cost. Therefore, we need a proper management material inventories. This research re-establishes the existing safety stock and analyzes relationship between safety stock and service level. It suggests an economical re-order point based on safety stock considering service level, various demand and delivery time.

Droplet sizes produced from a mist blower should be adequate to get highly biological effects with a reasonable level of work performance. However the droplet sizes from the conventional nozzles of the mist blower were around VMD 95 to 469$\mu$ which were relatively large as compared with the recommended droplet sizes in liquid flow rate of 17.2 m$/ell$s with air flow rate of 16660$m^3$/s on the maximum travel distance of about 4.0 m. The velocity of air stream at the point where two fluids, air and liquid, impact each other, was tried to maximize as much as possible in order to enhance the atomization performance of a newly designed twin fluid nozzles with the same or better level of performance of the conventional mist blower, The configuration of nozzle orifice should be designed to enlarge the contact area between air and liquid to enhance the atomization.

This paper aims to develop the adequate quality cost model at a company which delivers ICT(information communication technology) services. One particular business unit was in the first instance selected and quality costs were then analysed at an organization level, for a department and for specific processes. Some areas were determined for quality improvement at each level and their causes were also investigated. However, the existing PAF(prevention, appraisal and failure) models reveled some limitations because the ICT services company included the different number of large and complicated business processes. The PAF model did not sufficiently highlight the detailed causes of failure costs. It did not also stimulate the relevant department's strong responsibility to improve such problems. Both micro PAF and process cost models were proposed in order to cope with this. In final, it explains the relationship between six sigma and quality costing, suggesting how to use the quality costing results as a means of promoting either continuous improvement or innovation in a case company.

The survey on food intake in Masan and Ulsan city in Gyeong -Sang nam -Do was done by college students of nutrition major under the direction of nutrition professors on August 2nd, 3rd and 4th, 1976. The number of subjects were 260 family members from 54 households. The results are as follow : 1. Daily caloric intake for adults was 1670 kal which was 61.8% of R.D.A.2. The intake of protein appears to be adequate (80g per adult per day ) but fat intake was about 23g which was 5.8% of total calory intake. 3. The level of calcium and iron intake was close to that of R.D.A. However the level of vitamin A & vitamin $B_{2}$ was below R.D.A.

Cloud systems are popular computing environment because they can provide easy access to computing resources for users as well as efficient use of resources for companies. The resources of cloud computing are heterogeneous and jobs have various characteristics. One such issue is effective job scheduling. Scheduling in the cloud system may be defined as a multiple criteria decision model. To address this issue, this paper proposes a priority-based two-step job scheduling algorithm. On the first level, jobs are classified based on preference. Resources are dedicated to a job if a deadline failure would cause severe results or critical business losses. In case of only minor discomfort or slight functional impairment, the job is scheduled using a best effort approach. On the second level, jobs are allocated to adequate resources through their priorities that are calculated by the analytic hierarchic process model. We then analyze the proposed algorithm and make a scheduling example to confirm its efficiency.

An increasing in quantity of multimedia data brought a new problem that expected data should be retrieved fast and exactly. The adequate representation is a key element for the efficient retrieval. For this reason, MPEG-7 standard was established for description of multimedia data in 2001. In this paper, we designed a Audio/Image Retrieval System based on MPEG-7 that can retrieve multimedia data like audio, image efficiently. And we integrated high-level and low-level schemas to retrieve datas for users.
