The purpose of this study is to identify the role of T-shaped skill between customer/supplier network and innovation performance of firms. To manage effectively the relationship between collaborative firms, firms need to have a prior related knowledge. The premise of absorptive capacity is that the organization needs prior related knowledge to recognize, assimilate, and apply new knowledge. In this context, T-shaped skill facilitates the learning of new related knowledge. The skill is thus a critical component of innovative capabilities. We found that T-shaped skill plays a mediating role in the relationship between networks and innovation performance. The conclusions and implications are discussed.

The DNA marker T1ex, originally developed from melon (Cucumis melo L.) for monoecy, was employed in chamoe, which is referred to as oriental melon. This marker shows size variations in monoecious melon. However, in chamoe, no such detrimental size variation was found in monoecious chamoe, and 99% association between flower phenotypes and genotypes of the T1ex marker was observed in 106 lines of chamoe. To evaluate the efficacy of the T1ex marker for marker-assisted selection (MAS), a total of 240 plants of chamoe breeding lines were screened using the T1ex marker. Among these, 98 varieties were selected. Although the T1ex marker might not be useful for MAS in melon, we found 100% concordance between genotypes and phenotypes for sex expression in chamoe. These results suggest that the T1ex marker will be a useful resource for MAS for monoecy in chamoe.

In this paper, we have developed a propagation loss prediction software with GUI (Graphic User Interface) functions, based on the geometrical ray optics model, which can predict radio parameters for the deployment of wireless indoor network. The program has two numerical modules consisted with electrical image and ray launching methods to implement UTD theory. The simulated results are compared with reported data measured in the foreign building environments for office and '一' type corridor, and measured and simulated results for the propagation loss agree with each other quite well. Simulation results for '一' type corridor and 'T' type corridor propagation environment are shown for reference.

In Korean beef market, one of the major problems is mislabeling or fraudulent distribution of Holstein dairy meat or imported beef as domestic Hanwoo meat. Therefore, there has been a great need for a development of technology to identify beef breeds in meat and meat products. This study was carried out to develop the accurate and reliable method for the identification of beef breed using PCR-RFLP marker of MC1R, MGF and TYRPl genes affecting coat colors in cattle. A single base substitution (G\longrightarrowT transition) at the codon for amino acid position 104 of MC1R gene was identified between Hanwoo and Holstein and Angus breeds. The change at this position creates Msp I restriction site in Holstein and Angus, but not in Hanwoo. When the DNA amplified products (537 bp) was digested with Msp I, Hanwoo meat showed a single band of 537bp, while two fragments of 329bp and 208 bp were observed in Holstein meat and Angus breed, respectively. Thus, breed-specific RFLP marker in the MC1R gene can be used to distinguish between Hanwoo meat and Holstein and Angus meats. In the RFLP genotype of MGF gene, the frequency of r/r type was 75％ in Manwoo, whereas the frequency of R/R was 80％ in Hereford breed. Holstein and Angus breeds showed 100％ for R/r type. Therefore, Hanwoo meat showed significant difference in the MGF genotype frequencies compared with those of Holstein meat and imported beef cattle breeds. However, TYRP1 gene showed the same genotype in all breeds examined. Thus, this TYRP1 gene can not be used as a molecular marker for breed identification. As a consequence, we suggest that RFLP markers of the MC1R and MGF coat color genes could be used as DNA marker for identification of Hanwoo meat from Holstein and imported meats.

Korea needs to create, diffuse, and exploit scientific and technological knowledge effectively through transforming its national innovation system from imitative system to creative one. For this purpose, it is necessary for Korea to nurture creative human capital (CHC), which are the main actor of generating S&T and innovation. This paper aims at discussing the strategies of nurturing creative human capital of government-sponsored research institutes (GRIs). In this paper, we argue that the management of creative human capital is particularly important for Korean GRIs because they deals directly with scientific and technological activities. For effective management of GRIs' creative human capital, we suggest a Model for Life Cycle Management of Creative Human Capital. This model is composed of four stages: inviting well-qualified researchers, strengthening mobility of researchers, providing special certificates to excellent researchers, and effectively exploiting retired researchers. We emphasize that each stage should form and reinforce a virtuous cycle. This paper argues that GRIs' creative human capital should be nurtured as 'Inverse T-Type Manpower', who have not only deep knowledge on their own special S&T areas but also broad knowledge on related areas, based on this Life Cycle Management Model.

This paper investigates the relation of invert U-shape between the M/B ratio and leverage ratio by market, firm size, and a level of technology of firm. Our sample consists of 510 manufacturing firms continually listed on the Korea Securities Market and Kosdaq Market from January 1, 2001 to December 31, 2008. The total sample consists of the Korea Securities Market(large firms, high technology industry) sample of 2,248(1,816, 1,704) observations and the Kosdaq Market(small and medium firms, high technology industry) sample of 1,632(2,264, 2,376) observations. The empirical results show that the relation of invert U shape appears on the sample of the Kosdaq Market, small and medium firms, and high technology industry. However, the relation doesn't appear on the sample of the Korea Securities Market, large firms, and low technology industry. These mutually different results may be caused by the relatively low M/B ratio of the latter.

The sperm quality is determined by the kinetic characteristics and acrosome integrity of the sperm. In the previous studies, analysis of semen quality had large errors because those experiments by using microscope had been conducted by people. In recent years, the molecular biological methods have been newly developed to complement the previous techniques. The ZAR1 gene is known to be a gene that affects early embryonic development in vertebrates, but there is no study of the association with semen. In this study, we analyzed the association between the kinetic characteristics and ZAR1 single nucleotide polymorphism (SNP) genotype. To detect the SNPs, we performed sequencing using genomic DNA from the whole bloods of Duroc pigs. We identified an SNP in the ZAR1 gene g.2540T>C. ZAR1 SNP genotypeing in 105 pigs revealed that the major and minor alleles were T and C, respectively. After we analyzed the association between the kinetic characteristics of sperm and the ZAR1 SNP genotype, we found a significant association in MOT (p<0.01), VSL (p<0.05) of the kinetic characteristics in the Duroc boars. It was confirmed that the boars with T allele were lower in MOT and VSL than C allele. Therefore, pigs with C allele are judged to be better at the MOT and VSL of semen. Based on these results, ZAR1 SNP genotyping may be a useful molecular biomarker to improve semen quality by applying molecular breeding technology.

Purpose: In Korea, the number of laparoscopy-assisted distal gastrectomies for early gastric cancer patients has been increasing lately. Although minimally invasive surgery is more beneficial, no reported case of a totally laparoscopic distal gastrectomy has been reported because of difficulty with intracorporeal anastomosis. This study attempts, through our experiences, to determine the feasibility of a totally laparoscopic distal gastrectomy using an intracorporeal gastroduodenostomy in treating early gastric carcinoma. Materials and Methods: We investigated surgical results and clinicopatholgic characteristics of eight(8) patients with an early gastric carcinoma who underwent a totally laparoscopic distal gastrectomy at the Department of Surgery, Our Lady of Mercy Hospital, The Catholic University of Korea, between June 2004 and September 2004. The intracorporeal gastroduodenostomy was performed with a delta-shaped ananstomosis by using only laparoscopic linear staplers (Endocutter 45mm; Ethicon Endosurgery, OH, USA). Results: The operative time was $369.4\pm62.5$ minutes (range $275\∼465$ minutes), and the anastomotic time was 45.1\pm14.4$ minutes (range $32\∼70$ minutes). The anastomotic time was shortened as surgical experience was gained. The number of laparoscopic linear staplers for an operation was $7.1\pm0.6$. The number of lymph nodes harvested was $31.9\pm13.1$. There was 1 case of transfusion and no case of conversion to an open procedure. The time to the first flatus was 2.8$\pm$0.5 days, and the time to the first food intake was $4.1\pm0.8$ days. There were no early postoperative complications, and the postoperative hospital stay was $10.0\pm3.9$ days. Conclusion: A totally laparoscopic distal gastrectomy using an intracorporeal gastroduodenostomy with a delta-shaped anastomosis is technically feasible and can maximize the benefit of laparoscopic surgery for early gastric cancer.
