This paper analyzes the effects of allocative efficiency on productivity in the manufacturing sector of Korea following Hsieh and Klenow (2009). The results of this research indicate that the overall allocative efficiency declined from 1990 to 2012. Using the method of Oberfield (2013), which allows inter-industry resource movement as well as intra-industry reallocation, we confirm that intensified misallocation generally results from intra-industry allocative inefficiency. The potential loss from instances of worsening misallocation is estimated to be approximately 0.6% points for each year, which is considerable in terms of the overall TFP. In terms of the firm size distribution, initially large establishments are more likely to expand if distortions are removed in most countries. One notable feature in Korea is that this pattern is pronounced. This implies that subsidies to unproductive small-sized establishments are heavily implemented.

Domestic architect office from a period of high growth from the 1970s to the '80s has been established as some of the large corporations or publicly traded corporation. 1997 IMF has pointed out there is a lot of need for improvement activities in accordance with the construction recession since the 2008 global financial crisis. In order to address these causes, the company's continuous efficient operation for accurate efficiency and competitiveness analysis was required. Leverage financial ratio indicators Study Using Data Envelopment Analysis Data Envelopment Analysis (DEA) model, how to find a benchmark for the improvement of the efficiency of inefficient enterprises in various sectors being. In this study, a comparison of the conventional DEA model and the DEA-AR model is used to analyze the efficiency and domestic architect office is to improve the management efficiency.

The purpose of this study was to examine: 1) the differences in the automation level by company characteristics(i.e., product category, product type, firm size); 2) the effects of company context(i.e., environmental uncertainty, task uncertainty) on the automation level; and 3) the effect of the automation level on manufacturing performance(i.e., quality, flexibility, time, cost). Data were collected from a mail survey. Four hundred eighty two questionaries were mailed to apparel manufacturers nationwide, and 60 responses were analyzed. The results revealed that: 1) mens and womens wear manufacturers and large manufacturers(i.e., the number of employees, sales volume) showed higher automation level; 2) environmental complexity positively affected the automation level; and 3) the automation level had a positive effect only on quality performance.

A six-year old bitch pregnant with prolonged gestation over about one month was ovariohysterectomied. The bitch was proved to be normal by physical and biochemical examination and had not a purulent vaginal discharge. A large firm mass was palpated in left caudoventral abdomen. Radiography identified the mass as a fetus. The abdominal ultrasono-graphy identified the fetus was dead. Caesarian section through the median raphe over linea alba was attempted. Adhensions were found between the uterus, stomach, spleen, urinary bladder, and abdominal viscera. Two fragments of bone were found in the abdominal cavity because of rupture of left uterine horn. Radiography and ultrasonography were proved to be of use to diagnose prolonged fetal mummification. Ovario-hysterectomy was considered to be choice of treatment to remove the prolonged mummified fetus.

Primary rib tumors occur in dogs at a much lower frequency than appendicular bone neoplasms. A 3-year-old 3.5kg female maltese was referred to the Veterinary Medical Teaching Hospital because of a 2-month history of severe coughing and a 1-month history of dyspnea, gaging, and anorexia. The plain thoracic radiography revealed a huge well-defined mass in the left thoracic cavity, and a diagnosis of primary rib chondrosarcoma was established by histopathologic evaluation of the surgical biopsy specimen. At operation, a 8-x12-x4.5-cm relatively large firm mass was found filling the lumen of the thoracic, which was diffusely attached to the left 2-9th rib. This mass oppressed the heart, left lung and diaphragm.

A case of cutaneous fibroma was diagnosed in the skin of the right hindlimb of a Korean indigenous cattle in Kyungpook province, Korea. Grossly, the protruding skin nodules consisted of a solitary mass $(1.5{\times}1.5{\sim}3.0{\times}3.0cm)$ above large grapelike warty nodules $(11.0{\times}11.0cm)$ on the leg. These masses were firm and rubbery, and the cut surface was gray to white. Histopathologically, the benign neoplastic nodules consisted of spindle-type fibroblasts with collagen. Melanoma, sarcoma, and fibropapilloma were excluded because there was no sign of melanin, muscle type cells, or epidermal proliferation. To our knowledge, this is the first report of a cutaneous fibroma in a Korean indigenous cattle in Korea.

Flexibility and efficiency in producing a large number of productions in small-to-medium lot sizes are necessary to be competitive. Many firms are concerned about cellular manufacturing system(CMS) to surmount the abrupt change in management environment and to innovate their manufacturing systems. The purpose of this study 1) align BPR with CMS, 2) present the methodology for constructing a CMS and 3) apply to a firm ad verify it. The results of this paper are to present 1) the systematic methodology for constructing CMS at first in our country, 2) the methodology integrating managerial aspects, technological aspects and behavioral aspects, 3) the customer-oriented methodology based on customer value.

Hemangiopericytoma is a rare tumor of vascular origin, first described by Stout and Murray in 1942. It is characterized by a proliferation of capillaries, surrounding by a mass of spindle shaped or round cells. A 55 year-old man was admitted with a 2 years history of dull pain on the right upper posterior chest and mild dyspnea on Feb. 1978. On admission, chest PA and right lateral x-ray showed a large well defined homogenous increased density in the right upper posterior chest. Yellowish to brownish colored huge firm mass, which occupied entirely the right superior posterior mediastinum, was removed. The tumor was dense adhesive with right upper & lower lobe and Rt. upper posterior chest wall. The origin of tumor was not obvious. The tumor was confirmed as hemangiopericytoma, locating at the right posterior mediastinum by histopathologic examination. The postoperative course was uneventful, and he was made irradiation therapy after discharge.

The methodology of applying fabric stretch ratio in the grants pattern drafting was evaluated. The experimental fabrics employed in this study were 3 different knit fabrics with various stretch ratio in vertical or horizontal direction. The firm fitting pants pattern was modified by applying the fabric stretch ratio in vertical ana horizontal direction. The computer automatic drafting method was used for pants pattenl alteration. The suitability of the altered pattern was evaluated by the 7 clothing specialists, The results showed that fit of all experimental garments was improved in general. The garment which was constructed with the fabric having large difference between horizontal stretch ratio and vertical stretch ratio showed poor fit at crotch area. This result implies that computer aided pattern alteration is not appropriate when fabric stretch ratio is vary by the fabric directions.

Recently, Kim and Mauborgne [40] has introduced the concept of blue ocean strategy that provides quantum leap in value innovation, thus creating new market space. This study, based on the blue ocean strategy concept, suggests blue ocean new product development strategy (BONPDS), and attempts to examine how much this BONPDS has impact on new product peformance, compared to existing new Product development strategy Perspectives (i.e., competitive strategy-based new product development strategy and resource-based new product development strategy) in an empirical way. The research result shows that the BONPDS has greater impact on new product performance than existing new product development strategies. In addition, it is revealed that such contingency variables as firm size and environmental dynamism have moderating effect on the relationship between the BONPDS and new product performance. The BONPDS is more effective in the small-sized firms than the large-sized ones, and its effect on new product performance is different according to environmental dynamism.
