Purpose - This paper examines the relationship between corporate social responsibility and financial reporting quality. Corporate social responsibility is a way for firms to take responsibility for the social and environmental impacts of their business operations. Corporate social responsibility is a broad concept that can take various forms depending on the firm and industry. Through corporate social responsibility programs, firms can benefit society. At the same time, firms improve their reputations by increasing engagement in corporate social responsibility activities. However, corporate social responsibility activities are not directly related to profitability, especially for distribution firms. Research design, data, and methodology - 229 distribution & service firm-years between 2011 and 2016 are used for the main analysis. In Korea, Korean Economic Justice Institute evaluates the ethical performance of Korean firms, and the institute annually discloses the scores of top firms. This study uses the KEJI Index scores to measure firm-level corporate social responsibility activities. Discretionary accruals are used as a proxy for financial reporting quality. Discretionary accruals can be used opportunistically, and thus distort the information in earnings. We extract financial data from the KIS Value database. Results - We find that distribution & service firms' engagement in corporate social responsibilities is positively related to their financial reporting quality. First, there is a negative correlation between implementation of corporate social responsibility activities and discretionary accruals. In addition, we find that the coefficient of CSR is significantly negative, supporting our prediction. The result is significant at the 1% level. Conclusions - We examine the relationship between corporate social responsibility activities of distribution firms and their financial reporting quality while most prior studies examine the engagement in corporate social responsibility activities of manufacturing firms. The results of this study show that distribution & service firms engaging in corporate social responsibility activities are likely to maintain high-quality financial reporting.

Reexpansion pulmonary edema is not a common phenomenon after chest tube insertion but some reports from 0% to 14%. There are various resulting complications, including acute respiratory distress syndrome. We report a case of focal reexpansion pulmonary edema after chest tube insertion. A 49-year-old male came to the hospital due to ongoing dyspnea and left chest pain for 3 days. On chest X-ray, the patient had a left pneumothrax. We planned to insert a chest tube for symptom relief. To determine whether or not the chest had expanded as a result of the chest tube insertion, the patient underwent repeated chest X-rays the following day. The patient experienced brief respiratory symptoms upon initial suction; a chest PA showed patchy consolidated infiltration at the inserted site. After 5 days of conservative management, the recovered completely.

A certain number of products are transported to be sold each month and some of them are returned for repair. In this study we first assume that the transported products are the ones that have been sold, Then nonparametric approach is applied to the warranty returns data to see how the reliability decreases over time. Parametric approach such as Weibull distribution is applied to the same data and the results for both nonparametric and parametric approaches are compared. Next we assume that there is a time lag between shipment and sale. Then both nonparametric and parametric approaches are applied to the time-lag data and the results are compared.

Design-build, which is defined as single source responsibility for design and construction, has been widely used in large public works since governmental formulation of measure for encouraging use of design-build in 1996. However, civic groups and small and medium sized enterprises are highlighting over-competition and unbalanced market shares of conglomerate in domestic design-bid market and insisting on decrease in the use of design-build and absorption into the lowest-price bidding. This study collected information about cost, schedule, quality, new technology adoption from 51 civil design-build projects and measured their performance.

This study attempts to empirically investigate the excess returns of growth stocks in the Korean stock market comparing with those of value stocks. Recently, a few of IT and bio-pharmaceutical stocks with high growth potentials have accomplished dramatically high returns in the Korean stock market. Whereas, important prior studies in this line have observed negative excess returns from investment of growth stocks on average. And a few studies have reported that the distribution of excess returns from growth stocks is not normal but positively skewed. Empirical results of the present study are consistent with those of prior studies. Interestingly, the present study observed serial inverse correlation between excess returns of growth stocks and value stocks. Also, regardless of growth or value stocks, the stocks with higher PEG(=PER/ROE) showed higher excess returns.

Acute bilateral reexpansion pulmonary edema after pleurocentesis is a rare complication. In one case, bilateral reexpansion pulmonary edema after unilateral pleurocentensis in sarcoma was reported. Various hypotheses regarding the mechanism of reexpansion pulmonary edema include increased capillary permeability due to hypoxic injury, decreased surfactant production, altered pulmonary perfusion and mechanical stretching of the membranes. Ragozzino et al suggested that the mechanism leading to unilateral reexpansion pulmonary edema involves the opposite lung when there is significant contralateral lung compression. Here we report a case of bilateral reexpansion pulmonary edema and acute respiratory distress syndrome after a unilateral pleurocentesis of a large pleural effusion with contralateral lung compression and increased interstitial lung marking underlying chronic liver disease.

Churg-Strauss syndrome (CSS) or allergic granulomatous angiitis is a rare syndrome that is characterized by hypereosinophilic systemic necrotizing vasculitis affecting small- to medium-sized arteries and veins. In general, it occurs in individuals with pre-existing allergic asthma. When CSS appears in patients, it has the following characteristics: eosinophilia of more than 10% in peripheral blood, paranasal sinusitis, pulmonary infiltrates, histological proof of vasculitis with extravascular eosinophils, and mononeuritis multiplex or polyneuropathy. Therapeutic trials dedicated to Churg-Strauss syndrome have been limited due to the rarity of this disorder and the difficulty in making a histological diagnosis. Proper treatment of patients with CSS is not widely known. In this case study, we report on our experience with an unusual patient case, characterized by purpura and a perforation of the small intestine after inadequate steroid therapy.

In view of increasing environmental pollution, the organic farming in animal production is becoming increasingly urgent. The problems of veterinary medicine have not diminished through the most dangerous epidemic diseases. Organic farming attempts to function in harmony with the environment. The first criterion of the organic farm is that the animal must be self-sustaining. Their food must be produced to a large extent on the farm. The position of ruminants in biological systems is determined by the fact that this group of farm animals is provided with a digestive system which optimizes the utilization of the products of gut microfloral fermentation. The cattle do not require large amounts of concentrate feeling nor gross ugly farm building for intensive rearing. The economic profitability of a cow depends. on the first instance, on the level of milk production and the number of lactations. The length of life is an important factor since the tilde to maturing is relatively high in a cow. The result is that dairy cows in organic farming have greater length of live, and produce more milk in their life time than the shorter lived high input cow. This paper. therefore, discussed the problems of modern cattle farming and development trends of organic farming in Germany and Korea.
