Objectives : The present study examines the domestic trend of Chuna treatments on lumbar spinal disorder in Korea. Methods : We investigated the studies on Chuna treatments for lumbar spinal disorder via searching 10 Korean web databases. As a result, 63 research papers were found to be analyzed according to their published year, the titles of journals, the types of study, the techniques of Chuna, the instruments for assessment, the Chuna technique and the number of the treatment trials by the cases of lumbar spinal disorder and ethical approvals. Results : The number of the research papers published tends to increase every year. The studies on Chuna treatments were mainly published in The Journal of Korea CHUNA Manual Medicine for Spine & Nerves. The most frequently adopted technique of Chuna in the examined studies was Cox flexion & distraction technique. Visual analogue scale(VAS), oswestry disability questionnaire(ODI) were used as primary means of assessments. The ethical problems of the examined studies needed to be improved. Conclusion : Reviewing the domestic trend of studies on Chuna treatments for lumbar spinal disorder and examining the strong and weak points of those treatments are essential for the future studies. It is anticipated that this review benefits the future in-depth study on the treatments for Chuna in Korean medicine.

Flexural behaviors of two typical architectural precast beam sections ; inverted tee and rectangular - were compared and investigated. The heights of web in inverted tee beams are generally less than half of beam depth in building structures to accomodate the nib of double-tee where the total building height limited considerably. The inverted-tee beams are designed for parking live load - 500kgf/$\m^2$ and market - 1,200kgf/$\m^2$ according to the currently used typical shape in the domestic market building site in Korea. The bottom dimension and area of rectangular beams are same to those of inverted tee beams to compare the flexural behaviors of two beams. These two beams are also reinforced for similar strength. Four flexural tests are performed on two beams. Following results are obtained from the tests; 1) The rectangular beam is simpler in production, transportation, and election, and more economic than the inverted tee beam for these two beams with same dimension and similar strength. 1) The estimations of flexural strength of two beams by Strength Design Method and Strain Compatibility Method is fully complied with the result of tests. However, Strain Compatibility Method is slightly ore accurate than Strength Design Method. 2) Overall deflections of two type beam under the service loads are less than those of the allowable limit in ACI Code provision. 3) The rectangular beam is failed in large deflection (average 12.56mm large) than those of inverted tee beams. 4) The rectangular and inverted tee beams with 6m span develop initial flexural crackings under the 88% of full service loading even though they designed to satisfy the ACI tensile stress limit provisions.

This paper reports the numerical investigation conducted to study the influence of Local-Distortional (L-D) interaction mode buckling on post buckling strength erosion in fixed ended lipped channel cold formed steel columns. This investigation comprises of 81 column sections with various geometries and yield stresses that are carefully chosen to cover wide range of strength related parametric ratios like (i) distortional to local critical buckling stress ratio ($0.91{\leq}F_{CRD}/F_{CRL}{\leq}4.05$) (ii) non dimensional local slenderness ratio ($0.88{\leq}{\lambda}_L{\leq}3.54$) (iii) non-dimensional distortional slenderness ratio ($0.68{\leq}{\lambda}_D{\leq}3.23$) and (iv) yield to non-critical buckling stress ratio (0.45 to 10.4). The numerical investigation is carried out by conducting linear and non-linear shell finite element analysis (SFEA) using ABAQUS software. The non-linear SFEA includes both geometry and material non-linearity. The numerical results obtained are deeply analysed to understand the post buckling mechanics, failure modes and ultimate strength that are influenced by L-D interaction with respect to strength related parametric ratios. The ultimate strength data obtained from numerical analysis are compared with (i) the experimental tests data concerning L-D interaction mode buckling reported by other researchers (ii) column strength predicted by Direct Strength Method (DSM) column strength curves for local and distortional buckling specified in AISI S-100 (iii) strength predicted by available DSM based approaches that includes L-D interaction mode failure. The role of flange width to web depth ratio on post buckling strength erosion is reported. Then the paper concludes with merits and limitations of codified DSM and available DSM based approaches on accurate failure strength prediction.

The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yi tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery or $appliqu{\acute{e}}$ pattern have a high artistic value in that its shapes are diverse, splendid and each one has its own peculiar elegance. As for the research method, I examined the Yi tribe's history, culture, traditional costumes and patterns through related books, research papers and inter web sites. As for the result, the Yi tribe's costumes consisted of a jacket, trousers or a skirt, an apron and a belt. Although the favorite color of the costume is black color, there are splendid embroidery or $appliqu{\acute{e}}$ decorations with the colors of red, yellow, green and purple on the chest or shoulder part of a jacket, the adjusting lines, cuffs or a part of a trousers and aprons. Patterns in their traditional clothing also show details that depict traditional cultural ideas that have long been formed in various fields, such as aesthetics, religion, philosophy, and customs. Moreover, most patterns displayed in their traditional clothing contain nature motifs and represent unique and beautiful designs; some patterns are even reminiscent of abstract paintings by modern artists. In conclusion, the traditional patterns of Chinese ethnic minorities reflect the values and notions of these races as well as decorative magnificence and a unique spiritual image. In other words, traditional patterns indicate the spiritual depth or symbolic stories beyond mere formative beauty.

Purpose: This qualitative study aimed to develop a substantive theory of the process of adaptation to motherhood in Central Asian-Korean immigrants to Korea. Methods: Individual, in-depth interviews were conducted from July to September 2017, with 18 women who emigrated of Korean ethnicity from Central Asia to Korea, and took care of their baby for at least a year after their first delivery in Korea. The interviews were audio-recorded and transcribed verbatim. Data from the transcriptions were analyzed through Strauss and Corbin's grounded theory method, and data analysis was conducted simultaneously with data collection. Results: As a result of categorizing the interview data through the process of open coding, 10 categories, with 31 subcategories and 102 concepts were drawn, and "growth as a Central Asian-Korean mother in an unfamiliar, historical hometown" was found to be the core category of the process of adaptation to motherhood in Central Asian-Korean immigrants to Korea. Conclusion: A characteristic of the process of adaptation to motherhood in Central Asian-Korean immigrants to Korea, drawn from this study, is that it differs according to the level of initiative to carry out interaction strategies, and the use of various supportive social resources. The findings indicate the need for Medicare eligibility adjustment for antenatal care, the extension of the visa renewal period during childbirth, the development of web- or mobile application-based educational programs in Russian language, and the establishment of integrated visiting healthcare services, community service resources, and policy support to enable these women to utilize various supportive social resources.
