The 'Green Start Movement' is a practical movement of green living to efficiently reduce the greenhouse gases originating from non-industrial fields such as household, commerce, transportation, etc. for the 'materialization of a low carbon society through green growth (Low Carbon, Green Korea)'. When the new government took office, following the Lee Myeongbak Administration that had presented 'Low Carbon, Green Growth' as a national vision, it was required to set up the direction of the practical movement of green life to respond to climate change persistently and stably as well as to evaluate the performance of the green start movement over the past 5 years. A questionnaire survey was administered to a total of 265 persons including public servants, members of environmental and non-environmental NGOs, participants of the green start movement and professionals. In the results of the questionnaire survey, many opinions have indicated that the awareness of the green start movement is increasing and the green start movement has had a positive impact on individual behavior and group behavior in terms of green living. The result shows, however, that the environmental NGOs don't cooperate sufficiently to create a 'green living' effect on a national scale. Action needs to be taken on the community level in order to generate a culture of environmental responsibility. The national administration office of the Green Start Movement Network should play the leading role between the government and environmental NGOs. The Green Start National Network should have greater autonomy and governance of the network needs to be restructured in order to work effectively. Also the Green Start Movement should identify specific local characteristics to support activities that reduce greenhouse gas emissions. Best practices can be shared to reduce greenhouse gas emissions by a substantial amount.

The purpose of this study is to examine and assess the major characteristics and changes of politics, economy, and diplomacy in Thailand in 2016. Specifically, it reviewed the New Constitution that was passed in 2016, the confrontation between different political forces and the trend of military regime around the New Constitution, and the political instability caused by the accession of the new king to the throne. This study also set out to figure out changes to the economy and foreign relations of the country, including its relations with South Korea, under the military regime and make predictions for the impact and future prospects of King Bhumibol Adulyadej's death on the politics and economy of the country. In 2016, the politics of Thailand took a step further toward the transfer of power to civil government and established a foundation for an authoritarian system. The draft of the New Constitution, which does not seem to be democratic, was approved by a referendum and enabled the military authorities to continue their political interventions, even after the general election. The New Constitution, in particular, reduces the power of political parties itself in addition to simply keeping the Thaksin's party in check; thus, anticipating ongoing conflicts between the military authorities and political parties. In this situation, the absence of King Bhumibol Adulyadej, who used to play a decisive role in promoting the political stability of the country, and the accession of the new king to the throne raise concerns about the acceleration of political instability, which has continued after the coup and influenced the diplomatic relations of the country. Today, Thailand is distancing itself from Western nations that do not recognize the current military regime including the U.S.A. and EU member states and instead maintains a rapidly friendly and close relation with China. In 2016, the economy of Thailand made a gradual recovery rather than high growth. The death of King Bhumibol Adulyadej has exerted limited direct economic impacts only on individual consumption and tourism and is not likely to cause a recession. An economic crisis will, however, be unavoidable if the political confrontations escalate before the general election to transfer power to the civil government.

Currently, Korea is changing into an ultra-aging society, and office workers retire at the age of 49.5 on average from their main jobs, and the national pension is delayed from 62 years old to 65 years old by 2034, so research is needed to prepare for the aging of office workers after retirement. The purpose of this study is to examine the factors affecting the intention to start a business after retirement and the mediating effect of another sense of success expectation on life after retirement, targeting office workers nationwide. Changes in individual attitudes and systematic institutional support are needed to prepare for a sustainable job until the age of 100 after retirement, that is, a start-up utilizing wisdom and experience in work life. As a result of the study, the ability to perform the goal as job performance, economic preparation for retirement preparation, preparation for external relations, and future anxiety have a positive effect on the entrepreneurial will, and the ability to use new technologies as job performance, and physical preparation for retirement. Preparation and preparation for internal relations were found to have no effect. In the influencing relationship between preparation for external relations and the will of start-up, and future anxiety and will of start-up, another sense of success was confirmed to have a partial mediation effect. In the relationship between economic preparation and willingness to start a business, the effect of complete mediation was confirmed. In order to increase the will to start a business after retirement, it was confirmed that another sense of expectation for success was an important variable. Introducing a government-sponsored education system in the company to reduce the government's financial burden due to super-aging and achieve corporate growth through employee training while potential founders, office workers, are employed, and entrepreneurship and goals for the three life goals of office workers By introducing a performance improvement program, we were able to get implications that would be a solution to the growth of individuals and businesses and reducing the government's financial burden.

This study investigates the effects of social entrepreneurs' management competencies and background characteristics on public market performance. The government enacted the Social Enterprise Promotion Act in 2007 to create sustainable jobs and solve various social problems through social enterprises. However, contrary to expectations, the performance of social enterprise promotion has been criticized for being biased toward quantitative growth and not achieving the real policy goal of spreading the intrinsic competitiveness and net social functions of social enterprises. Under these circumstances, this study aims to investigate how the intrinsic competitiveness of social enterprises can be enhanced, especially in the public market supported by the government, by focusing on the mediating relationship between the public market performance of social enterprises and the management capabilities and experience characteristics of social entrepreneurs. The results showed that among the management competencies of social entrepreneurs, strategic competencies, technical and professional competencies, and marketing competencies have a positive effect on the public market performance of social enterprises, while managerial competencies have no effect on public market performance. Second, when it comes to the management capability characteristics of social entrepreneurs, we find that technical and professional capabilities, strategic capabilities, and marketing capabilities have a positive effect on experience characteristics, but managerial capabilities have no effect on public market performance. Third, in the test of the mediating effect of experience characteristics on the public market performance of social entrepreneurs' management competence characteristics, it is found that strategic competence and marketing competence have a statistically significant effect on public market performance, while technical and professional competence is not significant. In conclusion, experience characteristics have a partial mediating effect on the relationship between social entrepreneurs' strategic and marketing capabilities and public market performance, while experience characteristics have a full mediating effect on the relationship between technical and professional capabilities and public market performance. In order to create jobs and solve various social problems through fostering social enterprises as expected by the government, all kinds of policy support should be expanded to help social enterprises develop sustainable growth and development with intrinsic competitiveness, and in particular, various policy supports to facilitate social enterprises' entry into the public market should be considered, as well as various policy measures to help social entrepreneurs accumulate experience in various social economic activities and strengthen their management capabilities. In addition, it is essential to introduce policies to strengthen the capacity to enter the public market in policies for social enterprise leap forward and sustainability of social venture companies fostered by the government.

Early sexual maturation through temperature stimulation was induced in female and male of yezo scallop. Gonadosomatic index (GSI) in female showed $9.12{\pm}2.9$ in January, $14.89{\pm}2.9$ in February and $21.3{\pm}1.4$ in March in experiment I. GSI in experiment I showed a significant increase (P < 0.05) and in experiments II and III were not show significant variations (P > 0.05). It also showed significant between the control and the experiments I, II, and III in February (P < 0.05) measurements. Experiment I has showed good results in sexual maturation and spawning when compared with other experiments II and III and the control. Histological observation showed that ovary condition was in a growing stage in all the experiments I, II, and III. In February, ovary condition through histological observation was a late mature stage in all the experiments I, II, and III except the control of a growing stage. GSI and gonad weight were $4.4{\pm}0.88$ and 2.8 g, respectively in November whereas it was $15.1{\pm}2.8$, and 11.7 g, respectively in January and $21.7{\pm}5.4$, and 19.4 g, respectively in February after rearing at a water bath of $12^{\circ}C$ depending on the condition of experiment I. It was possible early releasing of eggs and sperms of yezo scallop in February instead of the middle of April to the end of May being spawning period. Fertilized eggs have become a gastrula stage through a spiral cleavage and then become a trochophore larvae after 36 hours. After 10 days, D-shaped larvae have changed into an umbo stage larvae and attached to juveniles in the post larvae after 20-23 days.

Histological and morphological development of the digestive tract of sevenband grouper were observed from after hatching to 60 days. Fishes were fed with rotifer (Brachionus rotundiformis) and chlorella (Chlorella ellipsoidea) after hatching from 2 to 20 days rotifer and brine shrimp (Artemia salina) in after 20 days rotifer, brine shrimp and semi-dry artificial diet in after 23 days. Histological and morphological development of ten larvae was observed by paraffin embedding method after fixing in 10% neutral buffered formalin. Sevenband grouper RLG showed characteristics of carnivorous fish by average 0.87. Larvae after hatching can't open the mouth and anus digestive tract was observed in a straight line following yolk sac. Larvae was observed feeding activity by opening the mouth and anus. Metamorphosis started 8 days after hatching. Esophagus divided four layer, and goblet cell was observed in esophagus, mid intestine and rectum. Larvae started cannibalism and it was caused by difference of growth. The inside of stomach was differentiated to cardiac orifice, body of stomach, pyloric stomach, and pyloric caeca. Goblet cell was observed all intestine. Gastric gland differentiated after hatching 28 days in stomach. Secretion of gastric juice was found at stomach and mucosal fold pyloric caeca. Even thought the inside of stomach expended and the number of gastric gland increased consistently and goblet cell in intestine and mucosa became longer, histochemical changes follow couldn't be found during transforming juveniles 38 days after hatching.

The increased concern for the security of the oil supply and the negative impact of fossil fuels on the environment, particularly greenhouse gas emissions, has put pressure on society to find renewable fuel alternatives. Compared to the traditional biofuel, ethanol, higher alcohols offer advantage as gasoline substitutes because of their higher energy density and lower hygroscopicity. For this reason, microbial fermentation is known as potential producers for sustainable energy carriers. In this study, bacterial responses including cellular and molecular toxicity were studied in three different microorganisms, such as Escherichia coli, Clostridium acetobutylicum, and Saccharomyces cerevisiae. In this study, it was analyzed specific stress responses caused by ethanol and buthanol using four different stress responsive genes, i.e. fabA, grpE, katG and recA. The expression levels of these genes were quantified by semi-quantitative reverse transcription-PCR. It was found that four genes have shown different responsive patterns when E. coli cultures were under stressful conditions caused by ethanol and buthanol, respectively. Therefore, in this study, the stress responsive effects caused by these alcohols and the extent of each stress response can be analyzed using the expression levels and patterns of different stress responsive genes.

Bulla is an air-filled space within the lung parenchyma resulting from deterioration of the alveolar tissue. Molecular mechanism of the formation of the bulla is not well described. Fibroblast growth factor(FGF)-7, bone morphogenetic protein(BMP) receptor, and transforming growth factor(TGF)-$\beta$ receptor are known to have a stimulatory or inhibitory role in the lung formation. We investigated to see if these growth factor or cytokine receptors are involved in the bulla formation by immunohistochemical staining of bullous lung tissues from patients with primary spontaneous pneumothorax. Material and Method: Bullous lung tissues were obtained from 31 patients with primary spontaneous pneumothorax, including 30 males and 1 female from 15 to 39 years old. The bullous tissues were obtained by video-thoracoscopic surgery and/or mini-thoracotomy and fixed in formalin. Blocks of the specimens were embedded with paraffin and cut into 5-6 ${\mu}{\textrm}{m}$ thick slices. The sections were deparaffinized and hydrated and then incubated with primary antibodies against FGF-7, BMP-RII, or TGF-RII. Result: Of the 31 patients, 24 were TGF-RII positive including 18 strong and 6 weak positives. Observation with high magnification showed that strong immunostaining was detected in the boundary region between bullous and normal lung tissues. In contrast, all of the sections were negative with FGF-7 or BMP-RII antibodies. Conclusion: These results suggest that overexpression of TGF- P RII may be involved in the formation of bulla, although further molecular studies are needed to find out more detailed molecular mechanisms.

Small intestinal submucosa (SIS) is consisted with collagen and glycosaminoglycan as well as some growth factors which can stimulate cell activity. Recently, it has been recognized that SIS has been successfully examined in the bio-medical application as biomaterials without xenograft immune-rejection response. We prepared native SIS sheets and acid treated SIS sheets by acetic acid with 1 or 5-layered sheets, respectively. The water uptake ability of native and acid treated SIS sheets was examined to evaluate the possibility as wound dressings. Morphologies of SIS sheets were characterized by SEM and the effects of various buffer solutions and different pH solutions on the water uptake ability were observed for 16 days. We observed that the acid treated SIS sheets had higher water uptake ability than native SIS sheets. Also, the water uptake ability of these was slightly higher in various buffers than distilled water. In conclusion, this study suggests that native and acid treated SIS sheets could be useful for the applications of wound dressing and biodegradable injectable materials.

Over the last 3 years, the global food 3D printing market has grown at an average annual rate of 31.5% and has shown an industry size that reached about U$ 9.46 billion. Food 3D printing technology has the advantage of being utilizable in diverse ranges because it enables free design of existing foods so that foods can be produced according to individuals' tastes and purposes. Many countries around the world are producing food 3D printers to release trial products such as foods employing the advantages of food 3D printing. They are also attempting to apply food 3D printing in various fields such as combat rations, space rations, restaurants, liquid foods, foods for the elderly, diets for patients, and baby foods. Whereas the 3D printing market, which has a high growth potential and is expected to continue to expand in size, is highly likely to become a blue ocean, not only is food 3D printing technology small in South Korea, but also the overall ratio of 3D printing utilization and the scale of the relevant industry are small. This is attributable to the fact that South Korea has problems such as insufficient institutionalization compared to developed countries and delays in the development of standardized domestic materials. Therefore, this paper is intended to inform the necessity of food 3D printing and describe food 3D printing technology and food 3D materials in order to obtain the additional effect of vitalizing the South Korean food 3D printing market.
