제대군인들은 전직준비, 사회가 요구하는 전문성, 사회적응력 부족과 그리고 오랜 군생활로 인한 유연성 부족 등으로 제대 후 새로운 일자리를 구하는데 많은 어려움을 격고 있다. 매년 7천여 명 정도의 제대군인들이 사회로 복귀하는데, 국가를 위해 헌신한 이들에 대한 예우 차원에서뿐만 아니라 우수한 인력의 활용을 위해서 국가적 수준의 제대군인 취업 및 창업지원 노력은 절실하다고 볼 수 있다. 본 논문은 제대군인이 창업의사결정을 하는데 미치는 다양한 요인들을 검토함으로써, 이들이 제대 후 창업의사결정에서 어떤 난관을 극복하여야 하는지, 그리고 정책적 지원이 이루어진다면 어떤 지점에 초점을 맞추어야하는지 알아보고자 한다. 본 논문은 일반적으로 창업의도에 미치는 요소로 알려져 있는 개인적 특성, 인적 자본, 재정 자원과 같은 선행요인들을 볼 뿐 아니라, 제대군인이 가지고 있는 군복무 경험과 특성이 창업의도에 미치는 영향을 분석한다. 본 연구의 결과가 제대군인들의 창업정책과 창업교육에 반영될 수 있을 것으로 기대한다.

Background: Umbilical cord (UC) is a promising source of mesenchymal stromal cells (MSCs). We compared the characteristics of MSCs from cryopreserved UC with those from fresh tissues, and demonstrated the possibility of UC cryopreservation for acquisition of MSCs from cryopreserved UC. Methods: Each UC was sliced into two types ($1{\sim}2mm^3$ vs. 0.5 cm), and cryopreserved in liquid nitrogen using different media (autologous cord blood plasma, aCBP vs. RPMI 1640). A fresh aliquot of $1{\sim}2mm^3$-sized UC was used as control tissue. After one week, the cryopreserved tissues were thawed and cultured. For the 0.5 cm UC, a slicing step into $1{\sim}2mm^3$ was needed. Cell count, viability, proliferative activity, and surface antigens were determined from harvested MSCs. Several growth factors (EGF, IGF-1, PDGF, TGF-${\beta}$, bFGF, and VEGF), were measured from the culture supernatant. Results: Eleven UC were enrolled in the study. Efficiencies of obtaining MSCs were higher in cryopreserved UC using RPMI 1640, compared with use of aCBP; the same result was observed for 0.5 cm sized UC, compared with $1{\sim}2mm^3$ sized UC. No difference in proliferative activity was observed between MSCs from fresh and cryopreserved UC. The amount of growth factors in culture supernatant using RPMI 1640 was larger than that of fresh tissues. Conclusion: We obtained growth factors from the supernatant as well as MSCs from cryopreserved UC. As with a cord blood bank, in the future, cryopreservation of UC for acquisition of both MSCs and growth factors would be possible in a time of need.

Purpose : It was generally accepted now a days that the pathogenesis of preeclampsia, small for gestational age (SGA), intrauterine growth retardation and fetal origin of adult diseases were related with a endothelial cell dysfunction. The purpose of this study was to know the relation of such diseases by assessing the level of endothelin-1. Methods : SGA babies, newborns of preeclampsia and normal control mother were included in this study. Isolated endothelial cells were centrifugated and mixed with media in $37^{\circ}C$, 5% $CO_2$ to obtain confluent monolayer of cultured human umbilical venous endothelial cell (HUVEC). Endothelin-1 levels were determined by Endothelin-1 colorimetric (EIA) Kits. We examined the endothelin-1 level in the HUVEC supernatants from SGA baby, and newborns from preeclampsia as well as normal mother. Also, we compared the endothelin-1 level of cultured normal HUVEC incubated with serum from cord blood of SGA, babies of preeclampsia or normal control mother. Results : The endothelin-1 levels in cultured HUVEC supernatants of three groups showed no significant difference but the endothelin-1 levels of cultured normal HUVEC incubated with serum from preeclampsia mother or SGA mother was significantly higher than those from newborns of control mothers (P<0.05). Conclusion : These findings suggest that there may be the factor which affect the endothelin-1 level in serum of cord blood from SGA and preeclampsia.

Apgar score is most widely used evaluating indicator of newborn health, but it is very Subjective. Umbilical cord blood gas analysis is more objective and effective than Apgar score in evaluation of newborn status. Cord blood gas was changed slightly by processing of time after fetal birth. This study was undertaken to observe objectiveness and effectiveness of umbilical arterial blood gas analysis and effects of time interval of cord clamping to newborn health with 122 pregnant women and their babies. We observed following results : 1. There were poor correlation between Apgar score and umbilical cord arterial blood analysis in evaluating of newborn health (P>0.05). 2. There was no clinical significance of Apgar score or umbilical arterial blood gas analysis as single indicator in evaluating of newborn health (P>0.05). 3. Gas analysis and pH of umbilical arterial blood was more helpful in evaluating of newborn health than Apgasr score. 4. There were no significant effects of time interval of umbilical cord clamping to newborn health. 5. If there were no indications of early umbilical cord clamping, cord blood sampling at immediately after birth without cord clamping was more effective to evaluate newborn status.

For many years, there have been many researches and guidelines to improve the employment rate of discharged soldiers. However, there have not been enough effective analysis conducted about the outplacement service and improvement guidelines. That is the reason why the satisfaction level of governmental supporting programs for the discharged soldiers stays at low level. Therefore, a methodical approach is needed for the discharged soldiers who have dedicated their services for many years for the sake of the country's security. For this reason, tools which can support build an effective outplacement service for the discharged soldiers are required. In this study, psychological, structural and environmental aspect of discharged soldiers were surveyed at the cognitive level based on the soldiers waiting for the discharge from military service. As a result, it became clear that psychological advice or support and job training for the discharged soldiers who executed long-term service are urgent. In addition, an efficient system can control and maintain the system mentioned above.

Purpose : The purpose of this study was to evaluate the relationship between cord serum adiponectin (APN) and IGF-I concentrations and fetal growth. Methods : Umbilical cord serum APN and IGF-I concentrations were measured in healthy term singleton deliveries (n=72). The association of cord serum APN and IGF-I concentrations was evaluated in relation to birth weight, height, head circumference, gender, ponderal index, placental weight, feto-placental (F/P) weight ratio, maternal weight gain, and maternal body mass index (BMI). Results : The mean cord serum APN was 29.2${\pm}$10.46 $\mu$g/mL. The cord serum APN and birth weight demonstrated a bell-shape relationship. The cord serum APN concentration was higher in females than males (P=0.001). The cord serum APN was negatively correlated with maternal BMI (r=-0.301, P=0.027), but the mean cord serum APN concentration was not correlated with birth height, birth head circumference, ponderal index, placental weight, F/P ratio, or maternal weight gain. The mean cord serum concentrations of IGF-I was 51.26${\pm}$21.54 ng/mL. The cord serum IGF-I concentration was positively correlated with birth weight (r=0.312, P=0.009), but not birth height, ponderal index, placental weight, F/P weight ratio, or maternal BMI. Conclusion : APN demonstrated a bell-shaped relationship with birth weight in healthy term infants. IGF-I was highly correlated with fetal growth, especially birth weight.

Purpose: The purpose of this study was to evaluate the relationship between cord blood adiponectin and insulin-like growth factor (IGF)-I and their effect on fetal growth and insulin resistance in mothers with gestational diabetes mellitus (GDM). Methods: Cord blood adiponectin and IGF-I were compared between mothers with GDM (GDM group, N=53) and controls (non-GDM group, N=101). Neonates were classified into three groups of small for gestational age (SGA, N=26), appropriate for gestational age (AGA, N=97), and large for gestational age (LGA, N=31) by birth weight. The association between cord adiponectin and IGF-I levels was evaluated in relation to maternal and neonatal clinical data. Results: Cord adiponectin was lower in the GDM group than in the non-GDM group (P<0.001). There was no significant difference in cord adiponectin among the SGA, AGA, and LGA groups in the GDM group (P=0.228). The cord adiponectin of AGA in the GDM group was significantly lower than that in the non-GDM group (P<0.001). The most powerful predictor affecting cord adiponectin was the result of maternal 75 g oral glucose tolerance test. The cord IGF-I values between the GDM group and the non-GDM group were not different (P=0.834). Neonates with the heavier birth weight had the higher cord IGF-I levels. The most powerful predictor affecting cord IGF-I was birth weight and the next was maternal parity. Conclusion: Both cord blood adiponectin and IGF-I were associated with fetal growth, but IGF-I was a more general and direct factor affecting fetal body size, and adiponectin seemed to have more association with insulin sensitivity than growth.
