This paper aims to propose the strategy making in social enterprise for ensuring organizational sustainability and governance of social enterprise from systems thinking's perspective. Based on previous reviews on organizational sustainability and theories of governance currently advocated in the social enterprise literature, we use 'Holon Dynamics' approach, which is a synthesis of System Dynamics and Soft Systems Methodology (SSM), offers the problem-solving method for dealing with social contexts and "ill-defined" situations. To do so, a researcher carried out the interpretive action research using 'Holon Dynamics' approach from September, 2009 to August, 2010. The outcomes of research are summarized as follows. Firstly, systems methodologies are useful to offer a strategic choice that makes to achieve an organizational sustainability in the case of Korean social enterprise; 'the Rediscovery of Korea'. Secondly, systems thinking offers an alternative concept of system, which is known as an 'appreciative system' that is evolved from the mental constructs amongst participants in given situations. Lastly, the paper delineates the usefulness of systems thinking and the process of inquiry, which deal with social contexts (including cultural and political factors), are contributed to making the necessary conditions for organizational legitimacy and the appropriate strategic choice for social enterprise within combined functioning of the two roles of social and commercial activities from systemic perspectives.

The compensation system for residual land in our country is largely composed of the three sub-systems, that is, the purchasing compensation, depreciated compensation and construction expenses compensation. Among those, the purchasing compensation system mainly has problems in eligibility for compensation of the land, meanwhile, there is almost no problem in construction expenses compensation system. This study aims to examine the current depreciated compensation system for the residual land and its accompanying problems, and also review and compare those systems in USA and Japan with that of our country, and thereby discover the ways for the alternative solution for the compensation system in the viewpoint of policy.

Neuromodulation was introduced for patients with poor outcomes from the existing traditional treatment approaches. It is well-established as an alternative, novel treatment option for voiding dysfunction. The current system of neuromodulation uses an open-loop system that only delivers continuous stimulation without considering the patient's state changes. Though the conventional open-loop system has shown positive clinical results, it can cause problems such as decreased efficacy over time due to neural habituation, higher risk of tissue damage, and lower battery life. Therefore, there is a need for a closed-loop system to overcome the disadvantages of existing systems. The closed-loop neuromodulation includes a system to monitor and stimulate micturition reflex pathways from the lower urinary tract, as well as the central nervous system. In this paper, we reviewed the current technological status to measure biomarker for closed-loop neuromodulation systems for voiding dysfunction.

Since the industrialization of swine production in the late 1900s, swine farms in the United States, as well as in Europe, have largely become consolidated. Pig farms became larger in size but fewer in number, with 91% of market pigs being produced by large operations with 5,000 or more pigs on-site in the US, and only 3% of the total utilized agricultural land representing organic farming. Such change in the market made it difficult for small farmers to stay competitive, forcing them to find alternative ways to reduce the cost of production and increase profit using the outdoor production system. In contrast to the indoor confinement system, outdoor production system uses pasture-based units and/or deep-bedded hoop structures that promote animal welfare and environmental sustainability with a lower capital investment. In accord with the growing concern for animal and environmental welfare and food safety by the consumers, small farmers practicing an outdoor production system are seeing increased opportunities for marketing their products in the pork niche market. Unlike the general belief that the reproductive and growth performance measures of the outdoor sows and piglets are poorer in comparison with the animals reared indoors, studies showed that there was no significant difference in the performance measures, and some traits were even better in outdoor animals. Improved reproductive and production traits can increase the sustainability of outdoor farming. Present study reviewed the recent studies comparing the performance measures, meat quality and health of indoor and outdoor animals, as well as the efforts to improve the outdoor production system through changes in management such as hut types and breed of animals.

A review on the papers published in the Korean Journal of Air-Conditioning and Refrigerating Engineering in 1998 and 1999 has been done. Focus has been put on current status of research in the aspect of heating, cooling, ventilation, sanitation and building environment. The conclusions are as follows. 1) A review of the recent studies on fluid flow, turbomachinery and pipe-network shows that many experimental investigations are conducted in applications of impingement jets. Researches on turbulent flows, pipe flows, pipe-networks are focused on analyses of practical systems and prediction of system performance. The results of noise reduction in the turbomachinery are also reported. 2) A review of the recent studies on heat transfer analysis and heat exchanger shows that there were many papers on the channel flow with the application to the design of heat exchanger in the heat transfer analysis. Various experimental and numerical papers on heat exchanger were also published, however, there were few papers available for the analysis of whole system including heat exchanger. 3) A review of the recent studies on heat pump system have focused on the multi-type system and the heat pump cycle to utilize treated sewage as the heat source. The defrosting and the frosting behaviors in the fin-tube heat exchanger is experimentally examined by several authors. Several papers on the ice storage cooling system are presented to show the dynamic simulation program and optimal operation conditions. The study on the micro heat pipes for the cooling of high power electronic components is carried out to examine the characteristics of heat and mass transfer processed. In addition to these, new type of separate thermosyphon is studied experimentally. 4) The recent studies on refrigeration/air conditioning system have focused on the system performance and efficiency for new alternative refrigerants. New systems operating with natural refrigerants are drawing lots of attention. In addition to these, evaporation and condensation heat transfer characteristics of traditional and new refrigerants are investigated for plain tubes and also for microfin tubes. Capillary tubes and orifice are main topics of research as expansion devices and studies on thermophysical properties of new refrigerants and refrigerant/oil mixtures are widely carried out. 5) A review of the recent studies on absorption cooling system shows that numerous experimental and analytical studies on the improvement of absorber performance have been presented. Dynamic analysis of compressor have been performed to understand its vibration characteristics. However research works on tow-phase flow and heat transfer, which could be encountered in the refrigeration system and various phase-change heat exchanger, were seemed to be insufficient. 6) A review of recent studies on duct system shows that the methods for circuit analysis, and flow balancing have been presented. Researches on ventilation are focused on the measurement of ventilation efficiency, and variation of ventilation efficiency with ventilation methods by numerous experimental and numerical studies. Furthermore, many studies have been conducted in real building in order to estimate indoor thermal environments. Many research works to get some information for cooling tower design have been performed but are insufficient. 7) A review on the recent studies on architectural thermal environment and building mechanical systems design shows that thermal comfort analysis is sitting environment, thermal performance analysis of Korean traditional building structures., and evaluation of building environmental load have been performed. However research works to improve the performance of mechanical system design and construction technology were seemed to be insufficient.

The global financial crisis, the instability of the global economy since the beginning of the growing economic interests of the countries to adjust to establish a new economic system was set up on occasion. Meanwhile, standing in the international trade environment, multilateral system of international trade for the country as the cumulative fatigue of open markets and trade liberalization as an alternative to lead the free trade agreements between countries. Currently in Korea and China, in addition to the geographical proximity in all areas, including economic exchanges and mutually dependent relationship that is deepening the world's No. 1 exporter in China and overseas investors have become partners. FTA with China by promoting the growth of emerging economies in the Chinese market by securing a stable economic growth of China as a driver of economic growth in the country to utilize the plan is being promoted from. This study is currently being promoted, in a discussion of the FTA's agricultural trade measures to address the challenges and poems. Agricultural trade with other goods to be different from the specificity of the discussion of market opening and liberalization of trade has been recognized in the main essentially nothing. We promote an FTA, according to one review and discuss the background and trends of the agricultural trade in a market, through the analysis of the status and trends and present problems for future bilateral trade negotiations with Korea for agricultural markets and propose countermeasures for. Agricultural trade, during a discussion of the FTA is essentially nothing in the review is expected to expand the bilateral trade in agricultural products, while protecting its agricultural markets to be trying to policy implications.

Antibodies are powerful and versatile tools to play a critical role in the diagnosis and treatment of many diseases. Their application has been enhanced significantly with the advanced recombinant DNA and heterologonous expression technologies, allowing to produce immunotherapeutic proteins with improved biofunctional properties. However, with currently available technologies, mammalian cell-based therapeutic antibody production, as an alternative for production in humans and animals, is often not plentiful for passive immunotherapeutics in treatment of many diseases. Recently, plant expression systems for therapeutic antibodies have become well-established. Thus, plants have been considered to provide an attractive alternative production system for therapeutic antibodies, as plants have several advantages such as the lack of human pathogens, and low cost of upstream production and flexible scale-up of highly valuable recombinant glycoproteins. Recent advances in modification of posttranslational processing for human-like glycosylation in transgenic plants will make it possible that plant can become a suitable protein expression system over the animal cellbased current production system. This review will discuss recent advances in plant expression technology and issues for their application to therapeutic antibody production.

The paper analyzes GMO legal system and the problems of its management in China and their suggestions to Korea. GMO has been arising as a principal alternative of grain while grain prices continue to climb. Although there has been concerns about GMO imported from China, it is true that we have not studied on China's legal system and the problems of its management in China. The paper believes that when Chinese government does not manage GMO primarily, we have a high possibility that China's GMO food will access to Korean market at any time, and threaten our health and safety. Hence, it is highly time to analyze how legally China treats GMO and what the problems of its management are. The paper found out problems of China's GMO management in three ways. Firstly, GMO legal system of China is confused and it has limitation of effectiveness. China has no regulations like "a law" to regulate GMO and regulations which exists now are not easy to apply in substance. Secondly, China has no administrative strictness to manage GMO. For example, the regulation which ministry of agriculture in China promulgated in March of 2002 started to use partially since 2003, 7. Thirdly, China, as a nation that administration superiors to, market does not do its roll to control GMO. It relates to the low concerns and care of Chines people about GMO. The paper shows suggestions and countermeasures according to problems of China's GMO management.
