The fruits of Schisandra chinensis and Prunus mume have been traditionally used in the Oriental countries as an astringent against diarrhea and abdominal pain, a protectant for liver disease, an antimicrobial, and a blood tonic. However, little is known about the extract of Schizandrae Fructus and Mume Fructus (SMF-Ex) on dextran-sulfate sodium (DSS)-induced colitis in mice. In this study, we investigated the protective effects of SMF-Ex on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. SMF-Ex was orally administrated the single dose (80 mg/kg, body weight/day) for 7 days with one time per day. SMF-Ex reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, increased disease activity index (DAI), and histological colon injury. SMF-Ex also inhibited significantly nitric oxide (NO) and prostaglandine $E_2$ ($PGE_2$) productions in DSS-induced colitis mice. Furthermore, SMF-Ex increased significantly an superoxide anion (SOD), catalase, and glutathione peroxidase (Gpx) activity of the colon tissue in DSS-induced colitis mice. These results suggest that SMF-Ex administration could reduce significantly the clinical signs and inflammatory mediators, and increase antioxidant activity in DSS-induced colitis model mice and is a good candidate for further evaluation as an effective anti-ulcerative agent.

Atopic dermatitis (AD) is a chronically relapsing pruritic inflammatory skin disease. To find new anti-inflammatory products for skin inflammatory disease such as AD and contact dermatitis, we produced the effective microorganism fermentation substance (EM-S) by fermentation of medicinal plants with effective microorganisms including photosynthetic bacteria, lactic acid bacteria and yeast, screened the effects of EM-S on NC/Nga model mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinae (Df) extract. Topically applied EM-S significantly reduced clinical severity score, ear thickness and histological grade in AD-like NC/Nga mouse model by Df antigen sensitization. In addition, the serum IgE and Th2 chemokine levels (TARC/CCL17, MDC/CCL22 and CTACK/CCL27) were significantly reduced by EM-S. Futhermore, skin tissue expressions of Th2 chemokines were significantly reduced by EM-S. These results demonstrate that topical application of EM-S may be improve the AD-like skin lesion by suppressing IgE and Th2 chemokines.

The purpose of this study is to suggest production planning model for women's apparel manufacturer, which are relevant to the situation of Korean clothing industry. The research was based on simulation method. The basic model for the simulation was developed based on the empirical data from six production fm. After verifying the basic model, low alternative production plans went through trial run. In order to suggest the application of these alternative production plans for various style numbers and lot sizes, the simulation results were compared in terms of product efficiency and product cost. The four alternative plans were as follows: 1. The first alternative was to spread out work loads among workers in order to resolve bottlenecks in work flow. So this was suited to manufacturers that had constant production without regard to changing seasons. 2. The second alternative was to merge the skirt and trouser production, which require less work load, in one line. In this line, a few machine was justified by production improvement. It was suited to cases which producted various style suits. The third and fourth alternative were using another subcontractor for assembling inner shell garments. These was compatible in manufacturers which had to product more styles and sizes of trousers and skirts than those of upper garments. 3. The third alternative was to reassign the same workers in production line. Thus, production was increased. 4. The fourth alternative was to except two worker in production line, so expenses of worker's wage was decreased. The four alternatives could be one of the cost effective manufacturing plans according to manufacturer situations.

This study analyzed the effects of women's SNS use on their alternative behaviors of managing health. This study paid attention to how women's behaviors of seeking information about poisonous menstrual products and alternative menstrual products would impact their intention to use alternative menstrual products. Mainly based on health belief model, 11 hypotheses were created and tested through a path analysis of survey data. Results from the path analysis indicated that SNS information about menstrual products were significantly associated with perceived advantage of alternative menstrual products and perceived sensitivity of poisonous menstrual products. In addition, four main factors-self-efficacy, perceived sensitivity, perceived advantage, and perceived disadvantage-were significantly associated with women's intention to use alternative menstrual products.

As de-schooling students (students who leave schools) have been produced and increased in middle and high schools every year since 1990s, urban alternative schools have founded with Seoul as the center. The objects of such urban alternative schools are de-schooling teenagers, and their educational goal is to make the students to discover their own values and grow as members of the community by accomplishing their healing and growth. Most of students in alternative schools have excessive self-centered feeling than ordinary people, and since they don't have exchanges with others, they have to receive holistic healing along with education. Here, 'healing' is a method of approaching to health through environmental, psychological, social and cultural supports unlike 'treatment' used for medical means. Therefore, holistic healing for alternative schools' students has to accomplish self-knowledge, self-control, and self-healing without repulsion through spaces of healing environments instead of heavy-handed exchanges. This study has integrated a theory of Max $L{\ddot{u}}scher$ who suggested a psychological healing theory in terms of internal character and a theory of Rudolf Steiner who suggested it in terms of practical and holistic sense and analyzed Sungmisan School, one of urban alternative schools in Seoul through the integrated theory. The analysis of the integrated theory are intended to emphasize the importance of healing environments and suggest methods in creating healing environments for urban alternative schools in the future.

These days, the use of alternative energy is recognized as one of countermeasures to rising oil prices and climate-change agreements. Especially, it is regarded as a main element to realize 'Low-Carbon Green Growth', one of the key policies of MB government. However, though alternative energy, renewable energy, is a main policy issue of the present administration, there are many problems to solve: the lack of recognition of its energy, the low level of its technology, its expert's shortage, and its limited application fields. Therefore, to stimulate the use of alternative energy in Korea and to change the recognition of this energy, it is needed to utilize it to urban street furniture that many people visit and use. In particular, if alternative energy is first applied to street furniture that needs energy for its management, the effect of publicity and energy saving will be so great. In this study, for the basic research to introduce and promote various alternative energy sources such as solar power, wind power, small hydro power, and human power, we analyzed the present condition of development of Korean and foreign street furniture items. Furthermore, we evaluated the level of development of these street furniture products and the design types of them and from these evaluations suggested the design direction that can solve problems in development and improve the possibility of application of these energy sources to these street furniture items. Through these analyses, this study aims to enhance the image of future environment-friendly city and make new index for the application of alternative energy.

One fundamental issue in ad hoc networks is the alternative node election problem, which reflects how well a sensor network is monitored or tracked by sensors. In this paper, we proposed EEAP(Energy-Efficient Alternative Paths). This is a method of selecting an alternative node for path routing management. When some node disconnection on the path routing, using pre-selected backup node provides immediately recover the path recovery. When selecting an alternative node of Step-Parents head node on the path management, the node's energy level and distance information are cared in context-awareness. This is not only increased the system's capacity cost effectively, but also reduce transmission power entire nodes consume energy. As a result, each node could efficiently management and improves the life time for mobile host and extends system coverage.

Using a sample from Korea Education Employment Panel(KEEP), this study attempts to ascertain determinants of demand for alternative education in Korea. It found that children's gender and duration of computer use exert a strong effect on demand for alternative education. Also, those parents, who show more interest in government's education policy; are less content with the schools their children are attending; and exhibit the higher likelihood of migration for children's education, appear to have the stronger tendency to seek alternative education for their children. Meanwhile, there was a significant difference between male and female students in the factors that influence demand for alternative education. For male students, duration of computer use and the parents' interest in government's education policy tend to matter. For female students, however, health condition seems to be associated with demand for alternative education. For both male and female students, those parents' who are more discontent with the schools their children are attending and/or have the higher likelihood of migration for children's education seem more likely to send their children to alternative schools.

Alternative education in Korea has grown into an educational movement since the 1990s. The alternative education is affecting and growing the public education system such as innovative schools, free semester systems, and high school credit systems. In 2021, an institutional foundation was also established to be recognized and supported as an educational institution. As a result of reflecting on the alternative education movement for 20 years, it is understood as stagnant lost time in the second half of the decade. It is discussing reorganizing the meaning of future-oriented "alternatives" with the new "alternatives". The poverty of educational philosophy has also been highlighted as an issue, but no special discussions have been underway. Thus, the study discussed to propose an educational philosophy that could capture the ideologies of alternative education. Critical pedagogy aims to foster human beings who are subjective, autonomous, active and self-reliant through conscious emancipation. In recent years, critical pedagogy have discussed ecological environment and feminism. The educational philosophy of scholars such as Freire and Illich was the basis of the early alternative educational movement. Considering this, the study discusses that Korea's alternative education movement can be understood through critical education and is reasonable as an educational philosophy for new alternatives in the future.
