The objective of this study is to examine the effectiveness of the strategy of hospital specialization by analyzing the differences in expected and perceived services, perceived service quality, satisfaction, and intentions to revisit and recommend the hospital to others between general and specialty hospitals. Data were collected using self-administered questionnaire from patients admitted to four study hospitals: two speciality and two general hospitals. The questionnaire was developed based on SERVQUAL to measure five dimensions of service quality. Four hundreds questionnaires were distributed to inpatients or their guardians and 282 returned questionnaires were used in the analyses. The significance of the differences in study variables between specialty and general hospitals were tested by t-test and $x^2$-test. The factor analysis result confirmed the construct validity of 28 questions asked to measure service quality and resulted in four dimensions of service quality: reliability, assurance, tangible and empathy/responsiveness. Cronbach's Alpha ranged from .9013 to .9358, that confirmed the internal consistency of answers. The study results indicated that patients who used specialty hospitals had higher levels of expected and perceived service, a higher level of perceived service quality, and higher levels of service satisfaction than patients who used general hospitals. Percents of patients who had the intention to revisit the hospital and to recommend the hospital to others were higher among patients in specialty hospitals. The most frequent reason to choose the hospital was the excellence of doctors in both general(29.9%) and specialty(43.8%) hospitals, that was followed by convenient transportation(15.3%) and someone know works at the hospital(15.3%) in general hospitals and other's recommendation(14.6%), and nice amenities(13.1%) in specialty hospitals. Although there were no significant differences in clinical department, age, and sex of patients between general and specialty hospitals, patients who visited speciality hospitals had higher levels of education and income than their counter part in general hospitals. These results suggested that specialty hospitals performed better than general hospitals. Specialization could be a viable strategy to tide over recent financial difficulties experienced by hospitals, particularly small- and medium-sized hospitals.

Objective: Chronic obstructive pulmonary disease(COPD) is characterized by persistent airflow limitations associated with chronic inflammatory response due to noxious particles or gases in the lung. Iron deficiency is associated with chronic inflammation, such as COPD. The aim of this study was to evaluate the relationship among iron deficiency, iron homeostasis, and inflammation in retired miners with COPD. Methods: The serum levels of ferritin, soluble transferrin receptor(sTfR), and transferrin saturation(TSat) as biomarkers for iron deficiency and high-sensitivity C-reactive protein(hsCRP) as a biomarker for inflammation and hepcidin as a biomarker for iron homeostasis were measured in 93 male subjects. Iron deficiency was defined as any one or more of (1) sTfR>28.1 nmol/L, (2) TSat<16%, and (3) ferritin< $12{\mu}g/L$. Results: Iron deficiency was found 28% of the study subjects. Median levels of serum hsCRP was significantly increased related to airflow limitation of COPD(GOLD 1, $0.09{\mu}g/dL$ vs. GOLD 2, $0.17{\mu}g/dL$ vs. GOLD $3{\leq}$, $0.30{\mu}g/dL$, p=0.010), and was positively correlated with hepcidin(p=0.009). Mean level of serum hepcidin was lower in COPD subjects with iron deficiency(p=0.004) and serum levels of hepcidin was negatively correlated with %$FEV_1$ predicted(p=0.030). Conclusions: These results suggest that high serum levels of hepcidin are related to severe airflow limitation or inflammation and can decrease iron availability, regardless of iron status.

Quality of Service (QoS) Guarantees grant ways for service providers to establish service differentiation among subscribers. On the other hand, service subscribers are also assured the level of service they paid for. In addition, the efficient level of service quality can be selected according to the subscribers' needs thus ensuring efficient use of available bandwidth. While network utility optimization techniques assure certain QoS metrics, a number of situations exist where some QoS goals are not met. The optimality of the network parameters is not mandatory to guarantee specified QoS levels. This paper proposes a joint data rate and power control scheme that guarantees service contract QoS level to a subscriber using Goal Programming. In using goal programming, this paper focuses on finding the range of feasible solutions as opposed to solving for the optimal. In addition, in case no feasible solution is found, an acceptable compromised solution is solved.

In order to obtain and maintain competitive advantage, under rapidly changing maritime environment, liners should make efforts to reinforce their logistics service capabilities. Most of all, for this, shipping lines should accurately recognize and evaluate their logistics service attributes. In the present research, various logistics service attributes for ocean carriers were selected from previous studies and the observed data for 6 main service attributes were collected through a questionnaire survey to 31 maritime experts. Moreover, shipping lines' relative logistics service capabilities were measured by an additional survey process. The comparative gravity between core evaluation factors were measured by AHP technique and the relative capability levels of 2 Korean liners and 5 foreign shipping companies were assessed by utilizing a fuzzy model. The empirical result presents that Korean liners are superior at customer service capability but inferior at freight rate competitiveness. This research shows that Korean liners are ranked at high position for overall logistics service capabilities and focusing on the differentiation strategy but not on the cost related strategy.

The purpose of this study was to analyze the difference in bakery choice attributes according to consumers' general characteristics and purchasing behavior. Among 350 questionnaires distributed to bakery consumers, 277 complete questionnaires (79.1%) were analyzed. Bakery choice attributes were classified into five factors: "environment and image", "bakery product features", "location", "employee service", and "price and sales promotion"; the mean scores of these factors' importance levels were 3.59, 3.58, 3.49, 3.36, and 3.00, respectively. Males considered 'employee service' factor significantly more than did females. Further, the importance level of 'employee service' factor was significantly greater as consumer's age increased. The importance levels of 'bakery product features' and 'employee service' factors were considered significantly more by consumers who spent KRW10,000-15,000 than those who spent KRW5,000 or less. 'Price and sales promotion' was considered to be more important by consumers who obtained information from the Internet than from the TV and radio. 'Location' factor was considered to be more significant as purchasing frequency increased. Such differences in importance level of bakery choice attributes according to consumers' gender, age, job, and purchasing behavior should be considered and applied to the development of marketing strategies targeted at consumers.

Objective of the study represents experiences of medical utilization of Psychiatric Outpatients. This research draws on information obtained from the 2008 National-wide sampling study of the Korean Healthcare Panel(KHP) conducted. The results of our study suggest the significance of variables such as the gender(p<.001) in the social demographical characteristics, the medical security type(p<.016), medical institution utilization(p<.012) treatment type(p<.004) in the utilization factors. In the case of medical utilization cost, the financial support factor(p<.018) showed a significant relationship. Depending on the particularities of gender, medical security type, financial support, medical institution utilization, treatment type were determined through a multiple logistics regression analysis. Gender showed that, among Psychiatric outpatient age of 30-59 level was 5.358 times and 60 years and older, their the second medical examination level was 4.490 times higher than Psychiatric outpatients under the age of 29. Health insurance type showed for the others medical allowance was 6.712 times higher than job health insurance and the other treatment was 0.395 times lower than drug treatment. Psychiatric outpatients utilization are rooted in the thoughts and factor levels of the Psychiatric patients and must be understood from the Psychiatric outpatients's perspective. The point is not only to gauge the patients research during Psychiatric medical utilization. The important of social community mental healthcare services levels goes beyond the goal of enhancing healthcare.
