The Self-Support Program was introduced as an antipoverty policy at 2002 year in Korea. But, the Self-Support Program's negative or positive effects have been debated from diverse perspectives to the present. Thus, in this paper, we analyzed the effects of the Self-Support Program using the survey data from program participants. Even though the effects of Workfare Programs can be evaluated by various indicators(ex. income, employment status, poverty status, etc.), in our analysis the effects of the Self-Support Program are evaluated by participants' self-reliant attitudes and behaviors. Major findings are as follows. First, we found that some kinds of self-reliant attitudes(ex. work commitment, self-esteem, etc.) were build up through participation on the Self-Support program, but some kinds of self-reliant factors(job competence and skill, self-sufficiency prospect, etc.) which are more relevant to the self-sufficiency were not build up thorough it. Second, we found the positive effects of the program among people who are females, olders, less educated, more healthy, and the participants who have acquired more certificate of qualifications. Third, we also found that self-support center's job training program, adequate task matching, agency climates and intra-networks influence on the positive effects of the Self-Support Program. These findings suggest that the Self-Support Program has not been successful up to now and it's reformations are required. It means that objectives of the Self-Support Program as an anti-poverty policy must be obvious and program contents must be diverse. And also program administration systems need to be reformed in oder to raise the effectiveness of the Self-Support Program.

The purpose of this study is to investigate the middle school students' allowance managing behaviors and consumer education by the educational subject in order to explore a desirable direction of consumer education for allowance management. Questionnaire survey was conducted with 468 middle school students in Gyeongnam. The major findings are as follows: First, as for recognition of consumer education, the consumer education from home was the highest, and then the from school and mass media followed in that order. Second, the average score of the students' allowance managing behavior was low. The fulfillment ability was relatively high compared to planning and evaluative ability. Third, as for overall allowance managing behaviors, the more promoted a students' level of consumer education from school and mass media, the more cultivated his/her allowance managing behaviors. As for allowance managing behaviors in accordance with sub-factors, students' planning and fulfillment abilities were more cultivated, the more promoted his/her level of consumer education from school and mass media. Students' evaluative ability was more cultivated, the more promoted his/her level of consumer education from school and mass media. Fourth, there were differences in educational contents the students wanted in accordance with the educational subjects of consumer education. The consumer education can be more practical when it is connected with home, school, and mass media, development of an educational program with such connection is necessary.

This study is based on workplace learning, which has revealed its significant influence in the previous enterprise case studies. Why do small business owners have the opportunity to participate in workplace learning based on authenticity? It was intended to clarify whether it was necessary and to increase the growth and development potential of small business owners based on its contents. Moreover, this study is focused on identifying the influence of workplace learning on management performance through this series of processes. In order to investigate the influence of small enterprise workplace learning on management performance, research hypotheses were set based on a review of previous studies, and empirical analysis was carried out. A total of 203 questionnaires were empirically analyzed using SPSS 18.0 program. As a result, first, workplace learning had partially significant positive influence on job satisfaction. Second, workplace learning had significant positive influence on management performance. Third, job satisfaction had significant positive influence on management performance. Fourth, job satisfaction had partial mediating effect in the relationship between workplace learning and management performance. The analysis result showed that among sub-factors of workplace learning, only formal learning did not affect job satisfaction and that job satisfaction did not have mediating effect in the relationship between formal learning and management performance. According to analysis, this was because in poor small enterprise environments, opportunities to participate in formal learning like external training or in-house training were not kept. In other words, poor small enterprise environments were plainly revealed from the managerial, economic and social standpoint. Therefore, there is a need to establish the foundation of growth for them to solve problems and develop win-win development capabilities and an institutional system that can make a contribution to policy and education, and management, by helping small enterprises keep opportunities to participate in workplace learning. In spite of these significant study results, there can be a limitation. For improving this limitation, further research will need to target diverse fields focusing on samples, which can explain relations of many different variables. Also, working-level relation research connected to studies that can highly enhance management performance will be required.

This experimental study was designed to verify the anti-aging efficacy of Eukmigihwangtang (EMGHT) and Rehmannia Radix, and determine the specific role and actions of Rehmannia Radix. Normal rat (2 months old), aging rat (8 months old), and pathologically induced rat (2 months old, injected 30mg/kg of streptozotocin) are observed to study the aging eliciting factors such as peroxide contents and enzyme activities. The following results were obtained in this study: 1. For the body weight changes, normal group given Rehmannia Radix showed decrease in the body weight compared to the control group, aging group given EMGHT and Rehmannia Radix showed significant decrease in the body weight, and STZ injected group showed suppression to the body weight loss when given EMGHT and Rehmannia Radix. 2. For the content changes in serum lipid peroxide, normal group showed increasing level as the rat gets older. Aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the lipid peroxide level compared to the control group. Decrease was more prominant in the group given EMGHT. 3. For the changes in serum hydroxyl radical, normal group did not show significant changes, but aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the hydroxyl radical level compared to the control group. Decrease was more prominant in the group given EMGHT. 4. For the changes in serum superoxide dismutase (SOD) activity, normal group did not show significant changes, but aging group given EMGHT and Rehmannia Radix showed significant increase in the SOD activity compared to the control group. STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the SOD activity compared to the control group. 5. For the content changes in hepatic lipid peroxide, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the lipid peroxide level compared to the control group. 6. For the changes in hepatic cytochrome P-450 activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease compared to the control group. Cytochrome b5 activity was significantly decreased only in the STZ injected group given EMGHT and Rehmannia Radix. 7. For the changes in hepatic aminopyrine demethylase and aniline hydroxylase activity, aging group given EMGHT and Rehmannia Radix showed significant decrease compared to the control group. STZ injected group given EMGHT and Rehmannia Radix showed significant increase in the aminopyrine demethylase activity, and showed significant decrease in the aniline hydroxylase activity compared to the control group. 8. For the content changes in hepatic protein bound-SH and nonprotein bound-SH, againg group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase compared to the control group. 9. For the content changes in hepatic glutathione level, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase compared to the control group. 10. For the changes in hepatic glutathione S-transferase activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase and decrease, respectively, compared to the control group. 11. For the changes in hepatic glutathione reductase activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase compared to the control group, while $\gamma$-Glutamylcystein synthetase activity did not show significant changes. 12. For the changes in hepatic superoxide dismutase activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease compared to the control group. From the above results, the antioxidant effects of EMGHT and Rehmannia Radix were proved, as well as the role of Rehmannia Radix, a chief of EMGHT, was examined. In addition, since no change was reconized as the quantity of Rehmannia Radix and the order herbs increased, the reasonableness on EMGHT was proven with respect to its composition and quantity. Thus, the significance of EMGHT could be objectively exmined in terms of its composition and quantity. Considering animals used in the experiment, there were obvious changes in aging rats and pathologically induced rats than in normal rats. Consequently, it was noticeable that EMGHT and Rehmannia Radix were working selectively on the subjects.

This study was conducted to identify the potential of rape stalk as a raw material for biorefinery process of rape flower. At first, rape stalk (RS) was immersed in distilled water (DW), acetic acid (AA), oxalic acid (OA), sulfuric acid (SA) and sodium hydroxide (SH) solutions, and the content of reducing sugars liberated from immersed RS was analyzed. Glucose, xylose, arabinose and sucrose were detected varying with the immersion type. In particular, 1% AA-immersion of RS for 72 hr was the most effective conditions to liberate glucose from RS. Secondly, the RS residues were used for elementary analysis and fabrication of fuel pellets. In addition to the solution type, concentration of immersion solutions (0%, 1%, 2%) and immersion time (24, 72, 120 hr) were used as experimental factors. The contents of nitrogen, sulfur and chlorine reduced effectively through the immersion of RS in DW, AA and OA solutions. For properties of RS-based pellets, bulk density and higher heating value of RS-based pellets greatly increased with the immersion of RS, and the qualities were much higher than those of the A-grade pellet of the EN standards. Ash content decreased remarkably through the immersion of RS, and was satisfied with the A-grade pellet standard. Durability was negatively affected by the immersion of RS, and did not reached to B-grade of the EN standard. In conclusion, acid immersion of RS can be a pretreatment method for the production of fuel pellet and bioethanol, but use of the immersed RS for the production of high-quality pellets might be restricted due to low durability of immersed-RS pellets. Therefore, further studies, such as investigation of detailed immersion conditions, fabrication of mixed pellets with wooden materials and addition of binders, are needed to resolve the problems.

Multiparous Hanwoo cull cows have been generally regarded to have poor meat quality compared to young and primiparous Hanwoo in Korea, and there have been few studies attempting to understand various feeding programs for the multiparous Hanwoo cull cow. In this study, the effects of a feeding program consisting of two different diets for multiparous Hanwoo cull cows on meat production and quality were tested in comparison to a commercially used diet. Diets for treatment consisted of two levels of crude protein contents, 14.28% and 12.70% for early fattening and finishing, respectively. For a control, commercially used fattening feed (12.39% crude protein) was used. Feeding trials were performed at three different farms. In farm A, 29 herds of multiparous Hanwoo cull cows were used for the treatment group and 3 herds for the control. In farms B and C, the number of animal herds for treatment and control were 8 vs. 3 and 11 vs. 4 herds, respectively. Experiment diets were fed for an average of 211 days and in treatment, early fattening diet was fed for 4 months and then finishing feed was fed until slaughter. Average daily gains, thickness of back fat, area of Longissimus dorsi, carcass weight, index of carcass weight, intramuscular fat, meat color and texture were analyzed after slaughter. Random effect model [8] was employed in effect analysis. Positive effects of treatment were found in terms of average daily gain, back fat thickness, Longissimus dorsi area, carcass weight, and intramuscular fat. Carcass yield index, meat color and texture showed a negative effect. In this study, significant results were not found in all factors analyzed because the variance between experiment farms was large, however the 90% confidence interval of summary effects of ADG, back fat thickness, Longissimus dorsi area and carcass weight were significant and that of carcass yield index, intramuscular fat, meat color and texture were less so. Conclusively, a high protein diet fed early during the fattening period in multiparous Hanwoo cull cows could have positive effects on meat production.

The Bagan, the central part of Myanmar, is dry zone where the mean annual precipitation is less than 600 mm for the last ten years. Forest in this region has been degraded due to biotic and abiotic disturbances. While there have been various efforts to rehabilitate the degraded area, the information on growth and physiological characteristics of planting species and the impacts of planting trees in the region still lacks. Therefore, this study was conducted to determine the growth and physiological water use efficiency characteristics of five species (Azadirachta indica A. Juss., Acacia catechu Willd., Eucalyptus camaldulensis Dehn., Acacia leucophloea (Roxb.) Willd. and Albizia lebbek (L.) Willd.) which are utilized as rehabilitation species in the dry zone and to identify the impacts of tree planting on microclimate change in dry zone. The growth and the foliar carbon isotope composition of seedlings and the above mentioned five species planted in 2005 were measured. And from February 2015 to January 2016, microclimatic factors air temperature and relative humidity at 60 cm and 2 m above soil, soil temperature, soil water contents and precipitation were measured at every 30-minute interval from the two weather stations installed in the plantation located in Ngalinpoke Mt. Range. One was established in the center of A. indica plantation, and the other was in the barren land fully exposed to the sunlight. Among the five species, A. indica and A. lebbek which showed higher water use efficiency could be recommended as rehabilitation species in dry zone. Planting trees in the dry area was shown to affect the change of microclimate with shading effects, declining temperature of the land surface and aridity of the air, and to contribute to conserving more water in soil by preventing direct evaporation and containing more water with fine roots of trees.

This study was carried out to evaluate the fruit and growth characteristics of selecting Vitis amurensis through functional material analysis and sensory evaluation in V. amurensis collected in Gangwondo. For evaluation of growth characteristics in V. amurensis, experiments were carried out by compared with the two grape cultivars 'Campbell Early' and 'Kyoho'. The full bloom and verasion time in V. amurensis was investigated faster than those of examined cultivar grapes, while harvest time was investigated latter than those of examined cultivar grapes, but agronomic characteristics was not thought significantly difference between cultivar grapes and V. amurensis. For evaluation of shoot growth phase, the growth curve was very similar to cultivar grapes. The berry size in V. amurensis showed that increases rapidly between 3 and 4 days after full bloom time, and approximately doubles between the second growth period and harvest time, and the berry development phase investigated that consist of two sigmoid growth periods separated by a lag phase. The berry weight and soluble solids in V. amurensis increased with the tree age, but acidity and total sugar contents decreased, and showed a special quality and stable growth according to vine age. To investigation of functional materials, the anthocyanin content in V. amurensis ranged from 16.6 to 50.2 mg/100 g, and the resveratrol content ranged from 0.143 to $0.236{\mu}g/100\;g$ which was higher than those of cultivar grapes. These result indicated that V. amurensis tended to have the useful material larger than cultivar grapes. Therefore, other edibility factors of V. amurensis collected in Gangwondo may contribute to breeding studies in Vitis. spp.

The purpose of this study was to evaluate the effects of container types on physiological characteristics of Zelkova serrata, Fraxinus rhynchophylla and Quercus serrata in the container nursery stage. We used 16 container types [4 growing densities (100, 144, 196 and $256\;seedlings/m^2$)${\times}4$ cavity volumes (460, 380, 300 and $220cm^3/cavity$)] and performed two-way ANOVA to test the differences in photosynthesis, photochemical efficiency and chlorophyll content among container types. Also, multiple regression analysis was conducted to correlate container dimensions with photosynthetic rate. Container types had a strong influence on photosynthesis of three species seedlings. Growing densities and cavity volumes had a significant interaction effect on photosynthetic rate, water use efficiency, stomatal conductance and chlorophyll contents except stomatal conductance of Q. serrata. In all three species, however, interactions between the two factors of container type were not found with regard to photochemical efficiency. Growing density was negatively correlated with photosynthetic rate of F rhynchophylla and Q. serrata, while cavity volumes positively affected on those of three species seedlings. The range of optimal container types was determined by multiple regression analysis based on photosynthetic rate. Consequently, optimal growing density and cavity volume of container by each tree species were found to be approximately $160{\sim}210\;seedlings/m^2$ and $430{\sim}460cm^3/cavity$ for Z. serrata, $130{\sim}150\;seedlings/m^2$ and $390{\sim}440cm^3/cavity$ for F. rhynchophylla and $130{\sim}170\;seedlings/m2$ and $420{\sim}460cm^3/cavity$ for Q. serrata, respectively. Application of adequate container will induce higher quality seedling production in nursery stage, which will also increase seedling growth in plantation stage.
