  • The oriental medicine based on the traditional chinese medicine has developed according to the historical and racial character respectively in China, Korea and Japan etcs. Particularly, the distinctive feature of Korea & Japan is characterized by the development of constitutional medicine compared with chinese medicine; Sasang Medicine of Korea and Ikkando Medicine of Japan. The constitutional medicines were so far developed by many clinical doctors, and in recent years much interest has centered on the application of these medicines in regarding originality, easiness and effectiveness etcs in treatment. Thus far only few attempts have been made at Ikkando medicine in Korea, what seems to be lacking, however, is practical application in clinic. Thus authors intend to help the clinical application by introducing Ikkando medicine to Korea oriental medicine through this paper. The Ikkando medicine was established by Dohaku Mori(1869~1931) and was known through the "Kampo Ikkando Medincine" which was published by his disciple, Kaku Yakazu(1893~1966), classified human beings into three types; type of blood stasis, type of stroke and type of allergy. The type of blood stasis may be responsible for factors which have occurred by a state of insufficient bleed circulation and blood stasis causing lesione of endothelial cells, and Tongdosan is mainly administrated. The predisposing factor of stroke's type is known as the excessive diet, and the prevalence of cerebrovascular accident is probably higher. In this type, it is likely that patients are prevented and cured with Bangpungtongsunsan. Allergy's type have three distinct types of childhood, adolescence and adult as to the age. Allergy's type of childhood predisposes patients such as these to upper respiratory infection and tuberculosis etcs, and Sihocheonggansan is frequently administrated. Allergy's type of adolescence has a tendency to rhinitis and infection of face legion etcs, and Heunggyeyeoungyotang is mainly administrated. Allergy's type of adult is subject to urogenital infection, and is more commonly treated with Yongdamsagantang. Judging from the above, we can say with fair certainty that Ikkando Medicine has considerable validity to clinical practice, though it should not be pushed too far.

  • This study was conducted to investigate a potential of Yellow poplar (Liriodendron tulipifera L.) as a raw material for the manufacturing of particleboard (PB) and oriented strandboard (OSB). PB panels were prepared at the parameters of $0.7g/cm^3$ density, 15 mm thickness, three-layer, $E_1$ grade urea-formaldehyde (UF) resin, emulsion wax, and hardener. OSB panels were manufactured with a density of $0.65g/cm^3$, thickness of 10 mm, and $E_1$ grade of UF resin. Particle size of the face layer of PB was 20~80 mesh with 7~9% moisture content (MC), while that of core-layer was 3~20 mesh with 3~5% MC, which was similar to the production condition of commercial PB. As a result, the manufactured PB panels with 15.8 mm thickness, $0.7g/cm^3$ density, and 5.8% MC satisfied the requirement of bending strength of 15 type PB of Korean Industrial Standard (KS F 3104). Both internal bonding (IB) strength and surface screw withdrawal resistance also satisfied the requirement of 18 type PB of the standard. But, the edge screw withdrawal resistance satisfied the requirement of 15 type PB of the standard. These differences in properties could be due to the slenderness ratio of raw particles. In case of OSB panels with 10.7 mm thickness, $0.68g/cm^3$ density, and 5.8% MC satisfied all the requirements of bending strength, screw withdrawal resistance, and IB strength of 18 type PB of the standard. These results suggest that Yellow poplar wood has a good potential as a raw material for the production of PB and OSB.

  • The purpose of this research is to share the experience of reflective practice of a Home Economics teacher professional learning community(PLC) operator and to share better suggestions through reflection on PLC operation. All conversation in the 18 sessions of the PLC totally from May 31st 2013 to May 19th 2014 was recorded and transcribed. All materials of PLC activity were qualitatively analysed. Its themes were grounded on its coding and categorization scheme. Findings and conclusions of this study are as followings. The experience of learning the PLC for a year has found that it is the power to keep the PLC alive: courage and anxiety to face anxiety and anxiety about new challenges, the importance of theme selection, a teacher with a reckless challenge, shares of becoming a leader. Through reflection, I learned that concerns require attention to other teachers and the need for a 'New Round' for ongoing meetings. I, as a operator, did not fully consider participant's different interest as well as a program for a new round due to the lack of management experience. It led to the low participations in latter sessions of PLC. Suggestions are put as solutions to improve these problems; (1) grouping participants by school levels when collecting participants, (2) setting operation period and program applying participants' opinions, and (3) operating short-term PLC with certain themes to immerse reaching goal and satisfaction in short time.

  • Analysis of the economic impact on Korean bioindustry companies was approached after Korea access to the Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity (hereinafter 'the Protocol') enters into force. Cost analysis of the economic impact is based on the size of bioindustry market, dependency ratio on genetic resources abroad, ABS (Access and Benefit Sharing) ratio for royalty ratio. Korean bioindustry companies would have had to pay extra ABS cost around 1.3-6.0 billion won for using genetic resources abroad, if the Protocol had entered into force in 2009. And this cost is estimated to be around 13.6 - 63.9 billion won in 2015. All ABS costs account only about less than 0.01% of total Korean bioindustry volume of target years. These show us that joining the Protocol will not significantly impact the bioindustry market in Korea. If the Protocol enters into force, genetic resources users have to pay PIC (Prior Informed Consent) and MAT (Mutually Agreed Terms) cost before accessing the genetic resources outside of their country, regardless of the accession status of the country. This ABS costs and terms on provided genetic resources will be determined by compliance between genetic resources users and providers. As a genetic resources provider, Korean bioindustry companies will have advantage over technology transfer agreements, royalties, licensing agreements, and taxes on profits from patents including traditional knowledge. Also, Korean bioindustry companies are expected to get various socio-economic benefits such as patent litigation and regulatory proceedings as a genetic resources provider. Considering the advantages and disadvantages of the Protocol that Korean bioindustry companies will face together, the socio-economic impact of the Nagoya Protocol on Korean bioindustry companies is negligible regardless of the accession status of Korea to the Nagoya Protocol.

  • Using data from the Korean Labor & Income Panel Study (KLIPS), this study investigates private income transfers in Korea, where adult children have undertaken the most responsibility of supporting their elderly parents without well-established social safety net for the elderly. According to the KLIPS data, three out of five households provided some type of support for their aged parents and two out of five households of the elderly received financial support from their adult children on a regular base. However, the private income transfers in Korea are not enough to alleviate the impact of the fall in the earned income of those who retired and are approaching an age of needing financial assistance from external source. The monthly income of those at least the age of 75, even with the earning of their spouses, is below the staggering amount of 450,000 won, which indicates that the elderly in Korea are at high risk of poverty. In order to analyze microeconomic factors affecting the private income transfers to the elderly parents, the following three samples extracted from the KLIPS data are used: a sample of respondents of age 50 or older with detailed information on their financial status; a five-year household panel sample in which their unobserved family-specific and time-invariant characteristics can be controlled by the fixed-effects model; and a sample of the younger split-off household in which characteristics of both the elderly household and their adult children household can be controlled simultaneously. The results of estimating private income transfer models using these samples can be summarized as follows. First, the dominant motive lies on the children-to-parent altruistic relationship. Additionally, another is based on exchange motive, which is paid to the elderly parents who take care of their grandchildren. Second, the amount of private income transfers has negative correlation with the income of the elderly parents, while being positively correlated with the income of the adult children. However, its income elasticity is not that high. Third, the amount of private income transfers shows a pattern of reaching the highest level when the elderly parents are in the age of 75 years old, following a decreasing pattern thereafter. Fourth, public assistance, such as the National Basic Livelihood Security benefit, appears to crowd out private transfers. Private transfers have fared better than public transfers in alleviating elderly poverty, but the role of public transfers has been increasing rapidly since the welfare expansion after the financial crisis in the late 1990s, so that one of four elderly people depends on public transfers as their main income source in 2003. As of the same year, however, there existed and occupied 12% of the elderly households those who seemed eligible for the National Basic Livelihood benefit but did not receive any public assistance. To remove elderly poverty, government may need to improve welfare delivery system as well as to increase welfare budget for the poor. In the face of persistent elderly poverty and increasing demand for public support for the elderly, which will lead to increasing government debt, welfare policy needs targeting toward the neediest rather than expanding universal benefits that have less effect of income redistribution and heavier cost. Identifying every disadvantaged elderly in dire need for economic support and providing them with the basic livelihood security would be the most important and imminent responsibility that we all should assume to prepare for the growing aged population, and this also should accompany measures to utilize the elderly workforce with enough capability and strong will to work.

  • This study attempts to elucidate manifold dimensions of gendered accessibility experiences. How gender roles(household responsibilities) differentiate accessibility experiences between women and men is explored through the comparison of married dual-earner couples' parental status, using the US Portland activity-travel diary dataset with GIS-based geocomputation results of(time-geography based) space-time accessibility. First, this study shows how gender division of labor within the household still permeates current society, despite the widespread belief of the social change toward a gender-egalitarian society. Then, the study pays special attention to the way gender roles structure individual accessibility experiences of women and men differently, and, in turn, the way such accessibility experiences take a form of gendered spatiality. Gendered spatiality is examined through the analysis of accessibility space as well as activity space in order to ascertain women's home-attached and spatially entrapped characteristics. More household responsibilities throughout a day and, even more, the time constraint of picking up children at the daycare centers after work lead women's possible activity space to be more home-centered. The analysis of the spatio-temporal context of accessibility space makes gendered spatiality visible. However, the findings suggest that behavioral outcomes should be understood with an explicit awareness of constraints individuals face. It is because the revealed activity spaces can be not only an outcome of constraint but also an outcome of choice. Behavioral outcomes should not be treated as a straightforward expression of the level of constraints. It is problematic to expect that behavioral outcomes directly mirror the level of constraints. It is also problematic to suppose that the level of constraints can be straightforwardly elicited from revealed behavioral outcomes.

  • A shear strength model for the high-shear ring anchor consisting of a steel ring and a rod was developed based on the shear tests on single high-shear ring anchors. The shear strength was found to be proportional to $f_{ck}{^{0.75}}$ which is a similar characteristic to the strength of shear connectors used in composite structures. The effects of the compressive strength of concrete, edge distance, and embedment length of rod are included in the proposed model. Comparison with 22 tests shows that the average and the coefficient of variation of test-to-prediction ratios are 1.01 and 7.57%, respectively. Push tests on the specimens having four high-shear ring anchors at each face were conducted and the measured shear strengths were compared with the predictions by the proposed model. For the specimen with an edge distance of 100 mm, a splitting failure occurred and for the specimens with an edge distance of 150 mm, a failure mode mixed with splitting and bearing occurred, which were very similar to the failures of shear tests on single high-shear ring anchors. In case of a splitting failure, the overlap of failure surfaces could be prevented by providing the longitudinal spacing of 400 mm which is four times of the edge distance. In case of a bearing failure, the failure area is less than 150 mm from the center of the anchor and therefore the overlap of failure surfaces could be prevented by providing the longitudinal spacing of 200 mm. The average of the test-to-prediction ratios of Push tests is 98%, which means that the proposed mode can be applied to predict the shear strength of the multiple high-shear rings.

  • This study performed quantitative analysis of isoflavone glycoside contents on Buseoktae, Daewon, Wooram beans and cheonggukjang made of Buseoktae beans from the LC/MS/MS. Also, the experiment carried out by means of RSM(response surface methodology), which included 10 experimental points for the two independent variables addition(40, 55, 70 g) and time(2, 3, 4 min) from the beginning point to boil of cheonggukjang. These were optimized using a Face-centered central composite design. Daidzein contents were $212.16{\mu}g/mL$ in Buseoktae, $212.21{\mu}g/mL$ in daewon, $158.54{\mu}g/mL$ in wooram beans. Genistein contents were $318.84{\mu}g/mL$ in Buseoktae, $310.50{\mu}g/mL$ in daewon, $262.71{\mu}g/mL$ in wooram beans. Total isoflavone contents were $532.50{\mu}g/mL$ in Buseoktae, $524.19{\mu}g/mL$ in Daewon, $422.71{\mu}g/mL$ in Wooram beans. Isoflavone contents of Buseoktae and Daewon were quite similar, relatively contents of Wooram beans were low. Total isoflavone contents of Buseoktae cheonggukjang (for business use) was $430.10{\mu}g/mL$ in A ($32^{\circ}C$, 96 h fermentation), $460.09{\mu}g/mL$ in B ($36{\sim}40^{\circ}C$, 30 h fermentation), $417.46{\mu}g/mL$ in C cheonggukjang($36{\sim}38^{\circ}C$, 72 h fermentation), B cheonggukjang was just a bit more than A, C cheonggukjang. The estimated response surfaces confirmed that the amount and time had significant effects on taste. The optimum condition of Buseoktae cheonggukjang taste was predicted to be 55.20 g addition at 2.92 min.

  • This study is about the re-validation evaluation of the family Relationship Scale (FRS), developed to measure the family relationship in the social work practice. This study aims at re-validating the FRS, developed and validated in by Yang in 2001 for more general utilization. The sample was married mates and females residing in Seoul. For Face Validity, the content analysis was performed, and the FRS was re-validated in the dimensions of Love & Caring, Acceptance, and Recognition, positive affection, empathy, and autonomy and flexibility for each area. Internal reliability was .93, and internal consistency among three dimensions was 93%. For Empirical Validity, the Construct validity, the Criterion validity, and the Discriminant validity were performed. Construct Validity was validated through factor analyses. Commonalities for the factor analysis was 54%, and the factor loading for each factor was over .45. The confirmative factor analysis also confirmed the fitness of the scale. For Predictive Validity of Criterion Validity, regression analysis showed that the family stress scores became lower as the scores of the family relationship became higher; the discriminant analysis revealed that the family stress turned low ill tile group of high scores of family relationship. The Correlation analysis for Concurrent Validity was performed and the results showed the positive and significant relationship with a couple communication level (r=54) and a parent-child communication level (r=64). Life satisfaction and mental health level also revealed significantly positive correlation to prove Convergent Validity. Physical health level revealed a weak relationship with family relationship providing the evidence of Discriminant Validity. Discriminance was also proved by the analysis of variance with demographics. Thus, Cross Validation was confirmed the validation of the FRS through the various analyses with the married population. This study result improved the validity generalization of the Scale and verify the generalized usage of this sociometric scale in the field of social work practice.

  • Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous purpura, abdominal pain, arthralgia and renal involvement. The clinical features of HSP have been reasonably well documented but there are still many gaps in our understanding of HSP. The aim of this study was to present the clinical features of 125 children with HSP and compare them with previous reports, placing particular emphasis on clinical information. Methods : We collected the clinical data of 125 patients with acute HSP who visited Chungbuk National University Hospital from March 1992 to April 2002. Data were expressed as the mean or $mean{\pm}SD$ and statistical analysis was performed using Chi-square approximation. P<0.05 was considered as significant. Results : The patient population consisted of 87 boys and 38 girls ranging in age from one to 14 years. HSP occurs throughout the year, but this study shows seasonal skewing, with most patients presenting from fall through spring and a paucity of cases in summer. All patients had non-thrombocytopenic purpura concentrated on the buttocks and lower extremities. Purpuric lesions were also scattered on the arms and occaisionally on the face and ears, but the trunk was largely spared. A recurrence of purpura was defined as the reappearance of a rash or other symptoms following resolution of disease for at least two weeks. The mean number of recurrences was 0.51. Eighty eight patients(70.4%), 18 patients(14.4%) and 67 patients(53.6%) complained of abdomianl pain, gastrointestinal bleeding and arthralgia, respectively. Nephritis occurred in 48(38.4%) patients. Fifteen boys (17.2%) developed epididymitis. Neurologic features occurred in 13(10.4%) and two(15%) of these were seizures. Conclusion : HSP all showing purpura as defined is characterized by various clinical features, including abdominal pain, arthralgia, epididymitis and nephritis which could occur before the appearance of purpura. Therefore, we suggest that the possibility of HSP should be considered in children before invasive procedures, even if the above symptoms and signs present without purpura.
