Background: Indonesia is one of the countries with the highest preterm birth rate. Preterm infants are more likely than term and normal weight infants to experience neonatal mortality and morbidity due to acute respiratory, gastrointestinal, immunologic, central nervous system, hearing, and vision problems. Kangaroo mother care (KMC) is a proven cost-effective intervention to help reduce mortality rates among preterm infants; however, it has not been fully implemented in hospitals. Purpose: Assess KMC knowledge and perceptions among health providers. Methods: This qualitative study was conducted from December 2015 to April 2016 and consisted of 21 in-depth interviews and 3 focus group discussions (FGDs). The 3 categories of health personnel in the study were clinical providers, hospital management representatives, and Indonesian Midwife Association members. Results: Most health providers know about the benefits of KMC including stabilizing temperatures, weight gain, and maternal-infant bonding and reducing human resources and labor costs. They were also aware of which newborns were eligible for KMC treatment. Their knowledge was mostly gained from observation or obtained from pediatricians and personal experience. They believed that a low birth weight infant in an incubator could not be treated with KMC and that it could only be practiced if a special gown was used when holding the baby. This perception could be caused by a lack of formal KMC training, leading to misunderstanding of its aspects. Conclusion: In conclusion, KMC knowledge of clinical providers in the 2 hospitals was sufficient, primarily due to their health-related educational background. Some perceptions could be potential barriers to or facilitate the implementation of KMC practice. These perceptions should be considered in future KMC training designs.

A significantly larger lateral load and moment are applied on a high speed railway bridge foundation than other bridge foundations. Therefore most of bridge foundations on Honam high speed railway project were designed by high strength steel pipe piles to resist lateral load and moment, which caused the increase of construction costs. In order to perform optimum design, it is important to estimate accurate lateral resistance when designing this type of structure. Lateral load tests were carried out based on the field design data with the purpose of examining the lateral behavioral characteristics of a railway bridge foundation. The standard load test method(ASTM D 3966) was used for field tests by applying twice of design load. Total four load tests were performed on high speed railway bridge foundations with strain gages installed by every 1m along piles to measure load-resistance characteristics under applied lateral loads. The back-calculated P-y curves from strain gages were compared with estimated P-y curves using theoretical methods based on geotechnical investment data. Back-calculated P-y curves from field tests for sand and clay ground conditions were presented in this paper, which are different from theoretical P-y curves. By using the research results of this study, more accurate estimations of pile design under lateral loads can be available for similar geotechnical conditions.

Customer retention is more emphasized for internet business than off-line shopping-malls. The loyals not only purchase a lot but also recommend the mall to new customers quickly using internet media, and there have been many studies on this subject. In this study, customer satisfaction and trust are suggested as preceding variables that have an influence on customer loyalty, and switching gains are suggested as a moderating variable between customer satisfaction & trust and customer loyalty. Many people think it would be easier to change business connection and customer loyalty for internet shopping-malls would be very low. This study, however, concluded that customer satisfaction and trust had a significant influence on customer loyalty even in internet shopping-mall, and that switching gains had moderating effect between satisfaction-attitudinal loyalty and trust-behavioral loyalty. These results are meaningful in that customer satisfaction or trust should be emphasized even on internet business and that switching gains can be strategic focus in building up customer loyalty and retention.

Objectives : This cross-sectional study aims to investigate the differences in general health status (GHS) and physical care burdens (PCB) of inpatient groups in long-term care hospitals (LTCH). Methods : The data of 228 patients were analyzed by integrating the electronic medical record (EMR) data of 2016, recorded by the nurses of hospitalized patients in the hospital. Results : There was a statistically significant difference in the GHS between the high-medical demand group and the other groups, but there was no difference in the GHS among other groups. The overall PCB was higher in the high-medical demand group than in the middle-medical demand, and cognitive impairment groups, but not in the problem behavioral group. Conclusions : The current classification of patient groups has shown limitations in terms of the basis of differential benefits of the groups. In particular, the PCB of the problem behavior group was not different from that of any group; hence, it should be adjusted through further study. To control the surge of medical care costs, it is necessary to improve the irrationality of the LTCH pay system in terms of the integration and continuity for elderly care.

Purpose: This study was carried out to understand the in-patients' experiences related on informed consent for examination, treatment or surgery. Method: The study was conducted with 578 patients who were admitted to the departments of internal medicine and surgery for examination, treatment or surgery requiring informed consent from November 1 to 30, 2004 at three general hospitals in Daegu, Busan and Gyeongsangbuk-do. The data was analyzed by using SPSS 11.5 for Windows. Results: Although the one who explains during the process of informed consent should be doctors, 6.6% was informed by nurses or others. In addition, the majority has been told for complications and risk while relatively fewer patients were informed for necessity, method and costs of the procedure, and no one ever heard of other alternatives or the right to terminate the procedure at any time. While 40% of patients were not the final decision-makers of examination, treatment or surgery, 11.9% of patients answered their opinions were not considered during the final decision-making process. Conclusion: The study suggest that the ethically appropriate informed consent has not been achieved in the clinical practice, and therefore it is necessary to develop the specific behavioral guidelines and nursing ethics education program for nurses in order to settle down the desirable informed consent at the dimension of nursing management.

This paper aims at suggesting several ways lo change financial vulnerability and to improve managerial capability of local public hospitals (LPHs) in Korea through the identification of factors affecting profitability. Several findings of the research are as follows: To begin with, LPHs exhibited a statistically significant difference in their profitability from one another, according to tile analyses of their profitable margins from tile general characteristics. It depends on the number of hospitals in the area, the population of the hospital-built area, the number of competing hospitals, the number of staff per 100 beds, the opening of special clinic, the educational function, and the capacity of rooms. However, there was no variable in the managerial characteristics, presenting a significant difference, in contrast with hospitals which have been managed by private companies and made a great amount of profits. Second, according to the analyses of profit differences in behavioral effort-characteristics, a statistically significant difference was revealed upon the basis of the efforts to improve the clinic service, invite special patients, and shorten the period of being hospitalized. Third, the result of analyses about the difference of profitability from medical care and finance is statistically significant in the rate of labor cost, the rate of management cost, bed-occupancy rate, and the period of being hospitalized. Fourth, according to the analyses of the factors influencing the net profit ratio of the entire capital, Adjusted explanatory power(Adjusted $R^2$) was shown up to 65.2%, which is high. To compare the adjusted explanatory power stage by stage, the first stage model applying only two variables such as structural and strategic characteristics exhibited 23.8%, and the second stage model adding financial characteristics showed 51.5%. The explanatory power was much improved up to 65.2% when the third stage model incorporated the outcome of medical care performance. When the return on investment(ROI) was examined by using the multi-variate linear regression analysis at the final model of third stage, it was found that ROI had a positive relationship with the increase rate of patients, labor costs per doctor, and medical care rate of socially protected inpatients. However, it revealed that ROI had a negative relationship with the ratio of labor costs, the number of patients per managerial staff, and occupancy rate of rooms, respectively. The research suggests that in order for LPHs to increase profitability, LPH, should make efforts not only to attract patients to the hospitals without any discrimination of the patients depending on their financial status, but also to develop efficient management methods to reduce labor costs.

Squid jigging fishery is very important in that there are about 1,000 jigging vessels more than 10 tonnage and about 5,000 ones less than 10 tonnage in Korea. But the cost of oil which is used to light fishing lamps, goes significantly up to almost one hundred million won for 50 tonnage vessels and forty million won in case of vessels less than 10 tonnage. This cost has almost taken 40% of total fishing costs. That is, the fishing business condition of squid jigging fishery is recently in the very difficult situation. As oil price increases, the business condition of the fishery gets worse and worse. Therefore it is very urgent to develop an economical fishing lamp, to solve this problem of fishery's business difficulty. This research aims at developing a fishing lamp for squid jigging fishery using the light emitting diode which has very excellent efficiency and durability. We made a water tank with 20 meters width which is a shape of raceway to research behavioral characteristics of Japanese flying squid to LED light, and made an experiment to investigate optimum wave of LED light to lure squid. The method is to establish LED lamps on both ends of water tank and to observe squid's behavior. Colors and wave lengths of LED lamps, used in experiment, are red(634nm), yellow(596nm), green(523nm), blue(454nm) and white(454nm+560nm). In experiment for attractive capability of LED lamp to squids, Japanese flying squid are highly attracted to blue lamp and white lamp. However, they are dispersed to red and yellow lamps. In addition, Japanese flying squid have moved and stayed in both dark ends of water tank. When compared intermittent lamp with continuous lamp, Japanese flying squid are highly attracted to intermittent lamp when intermittent interval is 0.25 second.

The aim of this study was to analyze the clinical characteristics of patients with cognitive and behavioral impairments receiving dental treatment under general anesthesia (GA-dental treatment). From August 2007 to April 2014, information was collected from 475 patients who received GA-dental treatment at the Clinic for Persons with Disabilities, Seoul National University Dental Hospital. The demographic factors (gender, age, disability, medication, GA history, residency type, caregiver, meal type, oral hygiene maintenance, and cooperation level) and dental status (operating duration, DMFT, malocclusion, periodontal disease, tooth defect, and treatment protocol) of the patients were evaluated. DMFT and malocclusion levels were compared among the patients with ANOVA and Sheffe's post-hoc test, and chi-square test, respectively. The correlation between the demographic characteristics and dental status of the patients were analyzed with the Pearson's correction test. The mean age of the patients was 27.1 (7 - 83) years and they had intellectual disabilities (55.4%), developmental disorders (17.9%), brain disorders (16.6%), neurocognitive disorders (4.6%), or others (5.5%). The mean DMFT (DT) was 8.6 (5.2) with a significant difference among the disability types (p<0.05). The incidence of malocclusion was higher in patients with intellectual disabilities and brain disorders than in the other types (p<0.05). The operation time ($191.4{\pm}91.2min$) was correlated with decayed or endodontically-treated teeth (p<0.05). Special needs patients requiring GA-dental treatment showed unfavorable oral conditions. Dental practitioners experience time restrictions and additional costs under a GA setting. Treatment planning and decision-making can be efficiently facilitated by evaluating the clinical characteristics of the patients.
