The importance of stepped single-crystal surfaces as model catalysts has been well recognized [1]. We re-investigated the adsorption properties of $H_2$ and CO, most important species in platinum-based catalysts, on nearly defect-free and highly stepped surfaces of one and the same Pt(111) crystal. While both being symmetric and single-peaked from the nearly defect-free surface, temperature-programmed desorption (TPD) spectra from the highly stepped surface saturated at 90 K with H and CO were triply- and doubly-peaked, respectively. Once pre-adsorbed, CO preempted step and then terrace sites, inhibiting the dissociative $H_2$ adsorption completely. Pre-adsorbed H inhibited the CO adsorption on terrace sites only, leaving defect sites intact for CO adsorption even at the saturation H precoverage. On defect-free Pt(111), while pre-adsorbed CO inhibited the dissociative $H_2$ adsorption completely, pre-adsorbed H could not inhibit the CO adsorption completely. These intriguing, but interesting results are discussed in terms of energetics/kinetics and the role of surface step sites in the dissociative adsorption of $H_2$ on Pt(111) [2].

The purpose of this study is to compare and analyze the process of hospital visits according to the characteristics of the elderly visiting to emergency medical centers. The subject of study was 571 patients over the age of 65 who agreed to participate in the study of emergency medical centers from May 1 to 31, 2010. The frequency, percentage and ${\chi}^2$ test of collected data were conducted with SPSS WIN 12.0. As a result, the frequency of the aged with or without urgency revisiting emergency rooms due to chronic degenerative diseases was high. In addition, there were many cases that the aged living only with a spouse or remaining single. It was obscure to classify them into a urgent or non-emergent group which made it longer time to visit a hospital. It may be necessary that the care for urgent elderly patients considering the characteristics of the family environment functions to care the elderly were weakened.

This study examines the effect of managerial ownership on firm value in capital markets where outside governance mechanisms to discipline managers are weak or non-existent. We hypothesize that strong market forces in the U.S. confound the effect of managerial ownership on firm value, i.e., the convergence of interest argument. We test the hypothesis using data from 112 firms from Singapore Stock Exchange and 205 firms from the Stock Exchange of Thailand prior to the Asian financial crisis in 1997 when the market forces were weak, yet the investor protection was sufficient to prevent outright appropriation from management. For ease of comparison, we use methodologies from studies done on the U.S. sample firms during the same study period as ours. We find that, both in Singapore and Thailand, firm value is a function of managerial ownership, and the relation is of the famous inverted U-shaped. Moreover, the relation is robust under different model specifications. The results from Thai sample, with weaker market forces than in Singapore, lend support to many agency cost hypotheses advanced in the U.S. Our results provide useful implication for investors in emerging and frontier markets where outside governance mechanisms are yet to be fully developed.

조절이론은 1990년대 중반 경제지리학에서 중요한 이론틀로써 조명을 받았지만, 한국에서 미처 충분한 조명을 받기도 전에 쇠퇴하였다. 이 논문은 조절이론을 2가지 형태 (1990년대 초기 접근과 2000년대 새로운 접근)로 재고찰함으로써, 한국자본주의 분석틀로써 적용가능성에 대해 고려해 보고자 한다. 여기서 우리는 조절이론을 한국에 적용시키는데 있어서의 어려움은 이론 자체의 근본적 한계를 드러내는 한편, 한국자본주의의 특유성을 보여주는데에도 유용하다고 주장한다.

Purpose: This study was done to examine the influence of nursing service quality and medical service satisfaction on intent to revisit the hospital, and to identify mediating effects of medical service satisfaction between nursing service quality and intent to revisit the hospital. Methods: This study was a cross-sectional survey. Participants were 390 hospitalized patients at one general hospital in Gyeonggi Province. Data were collected from July 21 to September 10, 2010 and analyzed using SPSS/PC version 18.0. Results: The score for nursing service quality continuously improved but the scores for medical service satisfaction and intent to revisit the hospital did not changed significantly after estimated. Factors influencing intent to revisit the hospital were nursing service quality, medical service satisfaction, 'same religion', and 'Christian', and the explanation power of these four factors was 79.7%. Medical service satisfaction had a partial mediating effect between nursing service quality and intent to revisit the hospital. Conclusion: Findings indicate that nursing service quality is a very important factor to improve both medical service satisfaction and intent to revisit the hospital. Nursing managers should develop strategies to improve nursing service quality.

The disease concept of interstitial lung disease with idiopathic pulmonary fibrosis at its core has been relied on for many years depending on morphological classification. The separation of non-specific interstitial pneumonia with a relatively good prognosis from usual interstitial pneumonia is also based on the perception that morphology enables predict the prognosis. Beginning with dust-exposed lungs, initially, interstitial pneumonia is classified by anatomical pathology. Diagnostic imaging has dramatically improved the diagnostic technology for surviving patients through the introduction of high-resolution computed tomography scan. And now, with the introduction of therapeutics, the direction of diagnosis is turning. It can be broadly classified into to make known the importance of early diagnosis, and to understand the importance of predicting the speed of progression/deterioration of pathological conditions. For this reason, the insight of "early lesions" has been discussed. There are reports that the presence or absence of interstitial lung abnormalities affects the prognosis. Searching for a biomarker is another prognostic indicator search. However, as is the case with many chronic diseases, pathological conditions that progress linearly are extremely rare. Rather, it progresses while changing in response to environmental factors. In interstitial lung disease, deterioration of respiratory functions most closely reflect prognosis. Treatment is determined by combining dynamic indicators as faithful indicators of restrictive impairments. Reconsidering the history being classified under the disease concept, the need to reorganize treatment targets based on common pathological phenotype is under discussed. What is the disease concept? That aspect changes with the discussion of improving prognosis.

This paper reviews researches related with the elderly caregiving, which hale published during the 1990s. After analyzingthe 29 articles in this field, the major findings are as follows: First, the advantageous position in life chances which is consisted of socioeconomic status and resources tends to reduce th burden for the elderly care. The higher in social status, the more resources older adults have, the more advantageous in controlling their relationship with their children and caregivers. Second, values based on familism is more associated with providing caregiving services for their parents than those of filial piety. Third, the tendency that daughter-in-law takes the role of the primary caregiver suggests a possibility of diminishing her enthusiasm, and finally comes to recognize her role as an enforced one, as time goes by. Fourth, cargiving burden affects the diverse aspects of caregiver's way of life. When the lower class elderly has dementia, caregiving stress and hassle have reached at their peak level. For meeting the needs of reducing the burden for the elderly care, this study suggests community- based approach for the elderly care. This approach attempts to share the caregiving burden with local community. To share the burden means that the boundaries of caregivers does not limit family members, but to expand community. This attempt includes a plan that establishes multipurpose community center which provides comprehensive services and care for the aged. The theoretical rationale of this approach are also discussed.

An analysis of light curves and spectra of observed gamma-ray bursts in gamma-ray ranges is frequently demanded because the prompt emission contains immediate details regarding the central engine of gamma-ray bursts (GRBs). We have revisited the relationship between the collimation-corrected peak luminosity and the spectral lag, investigating the lag-luminosity relationships in great detail by focusing on spectral lags resulting from all possible combinations of channels. Firstly, we compiled the opening angle data and demonstrated that the distribution of opening angles of 205 long GRBs is represented by a double Gaussian function having maxima at ~ 0.1 and ~ 0.3 radians. We confirmed that the peak luminosity and the spectral lag are anti-correlated, both in the observer frame and in the source frame. We found that, in agreement with our previous conclusion, the correlation coefficient improves significantly in the source frame. It should be noted that spectral lags involving channel 2 (25-50 keV) yield high correlation coefficients, where Swift/Burst Alert Telescope (BAT) has four energy channels (channel 1: 15-25 keV, channel 2: 25-50 keV, channel 3: 50-100 keV, channel 4: 100-200 keV). We also found that peak luminosity is positively correlated with peak energy.

Objective: To carry out the oriental medical treatment on a patient with vitreous hemorrhage in the left eye caused by diabetic retinopathy and record the results of the treatment. Methods: 1. Diagnosis: Fundus photography, Colored paper, Dr. Hahn's standard test chart for 5M, Blood sugar measurement. 2. Treatment: Acupuncture, Electro-Acupuncture, Indirect moxibustion, Western medicines, Oryoungsan(Crude drug preparations) Results: Oriental treatment using Ohaeng-acupuncture, Electro-Acupuncture, Indirect moxibustion resulted in the Unaided visual acuity of 0.1 while it used to be the left eye visual acuity with only light sense I month ago. Looking from Fundus photography result, progress was achieved and diabetic retinopathy was found to be in progress in fluorescein fundus angiography to right eye also by revisiting the patient after treatment. Conclusions: 1. Vitrectomy has many advantages but there are instances where patients do not recover their visual acuity due to complications. Therefore it is necessary to prove the effect oriental medical treatment through more cases in future. 2 For diabetic retinopathy patients, diabetes must be treated together with visual acuity.
