It is necessary for inmates released from prison to recover their career capital in order to function normally in society. Failure to adapt to the society may not only make them unhappy but could also aggravate social safety nets. Therefore, it is critical to examine the recovery of career capital. For this study, we conducted in-depth interviews of 10 rehabilitation recipients who were supported by Korea Rehabilitation Agency. For qualitative analysis, several career topics were analyzed, such as obstacles in recovering career capital, efforts in overcoming these obstacles, what is helpful for them to overcome the obstacles and what is required for them to adapt to the career life and others. Analysis results found that the rehabilitation beneficiaries suffered loses to their career capital due to their incarceration, suffered from the loss of pride and became despondent in the process of recovery of career capital due to the negative social perception toward their social self, fear of social stigma and devaluation of themselves. In addition, the fear of possible negative evaluation was a critical factor in making their social activities more challenging. Conversely, it was found that social support in the recovery process of career capital has a positive effect. In particular, emotional support from spouses, employers, family members and friends are the most positive factors. Concerning efforts at adapting to careers, it was found that an active, leading and positive attitude toward the career were critical, showing that positive evaluation and recognition in family and social relations and the experience of success in the career were positive elements in enhancing a sense of pride. In summary, it was found that in the recovery process of career capital, dysfunctional beliefs had a negative effect, while social support had a positive effect, on the recovery of career capital.

Large-scale discount stores, that were in charge of leading role up to recently, reach the limit of growth because of increasing competition, saturation of domestic market, and shortened product life-cycle. As per the limit of domestic market, large-scale discount stores are trying to various global market entry strategy and global marketing strategy like new store entry, takeover of foreign distribution chain, and global sourcing strategy. In the past, global companies of advanced country have been entering to Asian market with leading position. But, as per the rapid growth of Asian economy in the late 1980's, East Asian distribution companies like Japanese company were trying to enter the Asian market. In Asian market, starting with China, that was relatively not advanced in comparison with economic development, not only western advanced countries but also East Asian countries like Japan and Korea are entering actively for overcome their limitations of domestic market. Many of distribution companies experienced success and failure for various reason already. Korean large-scale discount stores are relatively late starters in Asian market. So, this paper purposed to review global market entry strategy of Japanese large-scale discount stores, and find out strategic implications for successful global market entry strategy of Korean large-scale discount stores.

Sepsis is the life-threatening response to infection which can lead to tissue damage, organ failure, and death. In the current study, the effect of orally administered D-glucose on the mortality and the blood glucose level induced by D-Galactosamine (GaLN)/lipopolysaccharide (LPS)-induced sepsis was examined in ICR mice. After various amounts of D-glucose (from 1 to 8 g/kg) were orally fed, sepsis was induced by injecting intraperitoneally (i.p.) the mixture of GaLN /LPS. Oral pre-treatment with D-glucose dose-dependently increased the blood glucose level and caused a reduction of sepsis-induced mortality. The oral post-treatment with D-glucose (8 g/kg) up to 3 h caused an elevation of the blood glucose level and protected the mortality observed in sepsis model. However, D-glucose post-treated at 6, 9, or 12 h after sepsis induction did not affect the mortality and the blood glucose level induced by sepsis. Furthermore, the intrathecal (i.t.) pretreatment once with pertussis toxin (PTX; $0.1{\mu}g/5ml$) for 6 days caused a reduction of D-glucose-induced protection of mortality and hyperglycemia. Furthermore, once the hypoglycemic state is continued up to 6 h after sepsis initiated, sepsis-induced mortality could not be reversed by D-glucose fed orally. Based on these findings, it is assumed that the hypoglycemic duration between 3 and 6 h after the sepsis induction may be a critical time of period for the survival. D-glucose-induced protective effect against sepsis-induced mortality appears to be mediated via activating PTX-sensitive G-proteins in the spinal cord. Finally, the production of hyperglycemic state may be critical for the survival against the sepsis-induced mortality.

PURPOSES : A geo-grid pavement, e.g., a stress-absorbing membrane interlayer (SAMI), can be applied to an asphalt-overlay method on the existing surface-pavement layer for pavement maintenance related to reflection cracking. Reflection cracking can occur when a crack in the existing surface layer influences the overlay pavement. It can reduce the pavement life cycle and adversely affect traffic safety. Moreover, a failed overlay can reduce the economic value. In this regard, the objective of this study is to evaluate the bonding properties between the rigid pavement and a SAMI by using the direct shear test and the pull-off test. The predicted fractural energy functions with the shear stress were determined from a numerical analysis of the moving average method and the polynomial regression method. METHODS : In this research, the shear and pull-off tests were performed to evaluate the properties of mixtures constructed using no interlayer, a tack-coat, and SAMI with fabric and without fabric. The lower mixture parts (describing the existing pavement) were mixed using the 25-40-8 joint cement-concrete standard. The overlay layer was constructed especially using polymer-modified stone mastic asphalt (SMA) pavement. It was composed of an SMA aggregate gradation and applied as the modified agent. The sixth polynomial regression equation and the general moving average method were utilized to estimate the interlayer shear strength. These numerical analysis methods were also used to determine the predictive models for estimating the fracture energy. RESULTS : From the direct shear test and the pull-off test results, the mixture bonded using the tack-coat (applied as the interlayer between the overlay layer and the jointed cement concrete) had the strongest shear resistance and bonding strength. In contrast, the SAMI pavement without fiber has a strong need for fractural energy at failure. CONCLUSIONS : The effects of site-reflection cracking can be determined using the same tests on cored specimens. Further, an empirical-mechanical finite-element method (FEM) must be done to understand the appropriate SAMI application. In this regard, the FEM application analy pavement-design analysis using thesis and bonding property tests using cored specimens from public roads will be conducted in further research.

Purpose: The appropriate management of traumatic truncal arterial injury is often difficult to determine, particularly if the injury is associated with severe additional truncal lesions. The timing of repair is controversial when patients arrive alive at the hospital. Also, there is an argument about surgery versus stent-graft repair. This study's objective was to evaluate the appropriate method and the timing for treatment in cases of truncal abdominal injury associated with other abdominal lesions. Methods: The medical records at Ajou University Medical Center were reviewed for an 8-year period from January 1, 2001, to December 31, 2008. Twelve consecutive patients, who were diagnosed as having had a traumatic truncal arterial injury, were enrolled in our study. Patients who were dead before arriving at the hospital or were not associated with abdominal organ injury, were excluded. All patients involved were managed by using the ATLS (Advanced Trauma Life Support) guideline. Data on injury site, the timing and treatment method of repair, the overall complications, and the survival rate were collected and analyzed. Results: Every case showed a severe injury of more than 15 point on the ISS (injury severity score) scale. The male-to-female ratio was 9:3, and patients were 41 years old on the average. Sites of associated organ injury were the lung, spleen, bowel, liver, pelvic bone, kidney, heart, vertebra, pancreas, and diaphragm ordered from high frequency to lower frequency. There were 11 cases of surgery, and one case of conservative treatment. Two of the patients died after surgery for truncal organ injury: one from excessive bleeding after surgery and the other from multiple organ failure. Arterial injuries were diagnosed by using computed tomography in every case and 9 patients were treated by using an angiographic stent-graft repair. There were 3 patients whose vessels were normal on admission. Several weeks later, they were diagnosed as having a truncal arterial injury. Conclusion: In stable rupture of the truncal artery, initial conservative management is safe and allows management of the major associated lesions. Stent grafting of the truncal artery is a valuable therapeutic alternative to surgical repair, especially in patients considered to be a high risk for a conventional thoracotomy.

Classical galactosemia (OMIM# 230400) is an autosomal recessive disorder of carbohydrate metabolism, due to a complete loss in galactose-1-phosphate uridyltransferase (GALT; E.C.2.7.7.12) enzyme activity. It caused by mutations in the GALT gene (OMIM$^*$ 606999) that is located at chromosome 9p13. The GALT enzyme deficiency results in a build-up of galactose and galactose-1-phosphate, causing life threatening complications such as feeding problems, failure to thrive, hepatocellular damage, bleeding and sepsis. However, Duarte galactosemia, a variant form of GALT deficiency, has residual GALT enzyme activities in erythrocytes and do not have manifest the symptoms of classical galactosemia. Since the advent of newborn screening (NBS) for galactosemia, we rarely encounter such overwhelmingly ill newborns. The positive NBS with no symptoms indicates the possibility of Duarte galactosemia besides a simple false positive and it has to be differentiated from classical galactosemia which is a medical emergency. In Korea, detection rate of Duarte galactosemia is very low and its genetic information is restrictive, too. We report a case of monozygotic twins with D/G galactosemia compound heterozygote in proven by the mutational analysis of GALT gene, which revealed N314D polymorphism and -119 to -116 delGTCA.

The Fukushima Nuclear Disaster in 2011 and California Power Failure in 2001 are examples of the importance of the power plant safety management that caused huge national loss with a power-related mass casualty incident. In a situation where humans cannot live without electricity, efforts to strengthen the systematic firefighting safety management in power plants that produce electricity with large amounts of hazardous materials as fuel, such as nuclear energy, coal and gas, are essential to protect life and prevent property loss and stable economic growth from fire explosion accident or radiation leak due to the negligence of safety management and natural disasters such as earthquakes, which has recently become an issue. This study examined the operating situation of firefighting safety management in power plants with firefighting officials employed by five power generation companies including Korea Southern Power Co., Ltd. and Korea Hydro & Nuclear Power Co. Ltd., which are in charge of the domestic power supply. As a result, for the systematic firefighting safety management of power plants, improvement plans were drawn, including the development of an effective business manual and a comprehensive management system, the substantiality of firefighting safety education, and the strengthening of seismic designs to prepare for earthquakes.

This study was carried out to scrutinize possibility of manufacturing pitch pine (Pinus rigida) glued laminated timber in order to add values of pitch pine trees. Also, it was investigated to improve bending performance of pitch pine glulam. Pitch pine was imported as one of major plantation species in Korean peninsula. Machine stress rated grades of pitch pine lumber mostly ranged between E7 and E9. which grades were more or less inferior to producing high quality glulam. However, the adhesive properties between pitch pine and pitch pine, and between pitch pine and Japanese larch (Larix kaempferi Carr.), such as shear bond strength, wood failure rate and de-lamination rate of bonded layer submerged in cold and boiling water, were higher than Korean Standard criteria. These properties are essential for manufacturing glulam with single species or multiple species. The modulus of rupture (MOR) of pitch pine glulam exceeded the criterion of Korean Standard for glulam strength grade but modulus of elasticity (MOE) was lower than the criterion. On the other hand, the bending performances (MOR and MOE) were improved 20 percent by mixing with Japanese larch laminar. It is effective to arrange higher quality Japanese larch laminar at the outer layer of glulam for improving bending performances. In conclusion, it is possible to use low quality pitch pine as laminar of structural glulam for adding values of pitch pine.

Most of the materials used in various industrial fields and also in our daily life are multi-component materials or composite materials, and it is well known that there are many cases where adhesion between the constituents within the bonded systems plays an important role. There are various types of performance evaluation tests for the bonded materials, among which tests for evaluating the bond performance under various conditions may be regarded as the most interesting ones for those engaged in work related to adhesion. I have studied on the mechanism of adhesion form the rheological standpoint with my colleagues, including some students from Korea, and I am very happy to be able to have a talk on some of our research works. In Japan, the so-called "adhesives" are usually classified into two categories;adhesives and pressure sensitive adhesives (PSA). Adhesives are the materials which solidify after bonding and are after used as the structural adhesives because the adhesive strength is comparatively strong. On the other hand, the pressure sensitive adhesives never solidify and are used as PSA tapes, labels or decals. About the adhesives, we have examined the dependence of adhesive strength(shear, tensile, peel) upon both temperature and rate of deformation, and found out some empirical rules which are applicable to most of the adhesive systems. We have also developed a simplified theory of adhesion, which is deseribed in terms of mechanical equivalent mode1 and a few failure criteria. Although some of the common rules can be accounted for according to this theory, it must be pointed out that a fracture mechanical approach ms inevitable especially in the region where the meehanical relaxation time of the adhesive is extremely large [W. W. Lim and H. Mizumachi]. About the pressure sensitive adhesives, we have studied on the PSA performance (peel, tack, holding power) as a function of both the viscoelastic properties and surface chemical properties of the materials, and found out some rules, and again we have developed a theory which deseribes the mechanism. And in addition, we have studied on the miscibility between linear polymers and oligomers, because PSA is generally manufactured by blending gums and tackifier resins. Many phase diagrams have been found and some of them have been analyzed on thermodynamic basis, and it became evident that the miscibility is a very important factor in PSA [H. J. Kin and H. Mizumachi]. In this presentation, I want to emphasize the fact that the adhesion performance is closely related to the structure/property of the adhesives.adhesives.
