  • Introduction: The first aim of this study was to isolate the dental tissue-derived stem cells from the dental follicle (DF), dental pulp (DP), and root apical papilla (RAP) of the extracted wisdom teeth. Second was to evaluate their characterization with the expressions of transcription factors and cell surface markers. Finally, their ability of the in vitro multi-lineage differentiations into osteogenic and adipogenic cells were compared, respectively. Materials and Methods: Dental tissues, including dental follicle, dental pulp, and root apical papilla, were separated in the extracted wisdom teeth. These three dental tissues were cultured in Dulbecco’s modified Eagle’s medium (DMEM) with supplements, respectively. After passage 3, the homogeneous shaped dental tissue-derived cells were analyzed the expression of transcription factors (Oct-4, Nanog and Sox-2) and cell surface markers (CD44, CD90 and CD105) with reverse transcription polymerase chain reaction (RT-PCR) and fluorescence-activated cell sorting (FACS) analysis. In order to evaluate in vitro multi-lineage differentiations, the culture media were changed to the osteogenic and adipogenic induction mediums when the dental tissue-derived cells reached to passage 3. The characteristics of these three dental tissue-derived cells were compared with immunohistochemistry. Results: During primary culture, heterogenous and colony formatted dental tissue-derived cells were observed in the culture plates. After passage 2 or 3, homogenous spindle-like cells were observed in all culture plates. Transcription factors and mesenchymal stem cell markers were positively observed in all three types of dental tissue-derived cells. However, the quantity of expressed transcription factors was most large in RAP-derived cells. In all three types of dental tissue-derived cells, osteogenic and adipogenic differentiations were observed after treatment of specific induction media. In vitro adipogenic differentiation was similar among these three types of cells. In vitro osteogenic differentiation was most strongly and frequently observed in the RAP-derived cells, whereas rarely osteogenic differentiation was observed in the DP-derived cells. Conclusion: These findings suggest that three types of human dental tissue-derived cells from extracted wisdom teeth were multipotent mesenchymal stem cells, have the properties of multi-lineage differentiations. Especially, stem cells from root apical papilla (SCAP) have much advantage in osteogenic differentiation, whereas dental follicle cells (DFCs) have a characteristic of easy adipogenic differentiation.

  • This thesis compares and analyzes the dynamics between policy, knowledge and power of Myanmar's higher education development. The papers begins by exploring the dynamics during the Socialist Military Regime(1962~1988), the Collapse of Higher Education Era(1988~2010), Thein Sein's Reform Era(2010~2015) and the current Aung San Suu Kyi's Civilian Era(2015~Now). By highlighting recent dramatic policy changes, the article argues that the policy discourse on the subject of internationalization of higher education and the technocratization of education development policy by the current Civilian Government in its new policy discourse, that resulted in the active participation as well as the contributions of international donors has directly impacted on the policy dynamics around the Comprehensive Education Sector Review and the introduction of the National Education Strategic Plan 2016~2020. Further, by examining complex interaction between the current domestic education stakeholders and international donors in education sector in Myanmar, this thesis argues that the new analytical framework on the understanding of policy dynamics in developing countries goes beyond the national level. The paper argues that there needs to be broadening of the analytical framework towards the multidimensional analysis perspective that includes global, national as well as local level policy, knowledge and power dynamics in Myanmar's dynamically changing higher education sector.

  • The construction procedures and artificial turf maintenance program on golf course definitely influence on the distortion of its environment. Soil microbial communities in soil profile were affected directly by those practises on turf areas. In Jeju island, the environmental impact assessment has been required to apply the first quality class granular activated carbon(GAC), which has a high absorbent character to agricultural chemicals, on the soil profiles of golf green system to reduce the pesticide leaching to ground water. This research was carried out to analyze the changes of microbial communities and chemical properties on soil profiles where GAC had been applied at the construction stage at two golf courses in Jeju. The changes of soil microbial population and chemical properties associated with construction methods of soil profile and agrochemical management program were analyzed by monthly at the surface and sub-soil profiles during April through October, 2007. The total numbers of bacteria and fungi, soil moisture content, soil physio-chemical properties were measured on greens and fairways of the both golf courses with different GAC treatment on the green and fairway soil profiles. The results showed that GAC had positive effects on the water holding capacity, pH and EC, however, it did not improved the holding capacity of available nutrients ${NO_3}^-,{NH_4}^+$, and phosphorus by its sorption phenomenon. In microbial count test, the total numbers of bacteria and fungi showed a great variation during sampling dates. That may directly relate to the agrochemical application, however, the ratio of total bacterial number versus total fungus number showed a constant value on a sub-soil of 15~30cm depth. Thus, the construction method of GAC in soil profile, and application of fertilizer and pesticide, both impacted on the changes of microbial population. It's means that the construction method of soil profile and turf management using agro-materials might greatly affect on the turfgrass culture and the environment of golf course.

  • This paper deals with a review of the structure and production techniques of the Dried-lacquer Amitabha Buddha statue enshrined in Geungnakjeon Hall of Simhyangsa Temple, located in Daeho-dong, Naju-si, Jeollanam-do, Korea. To achieve this goal, X-ray date and two rounds of field research were performed. The data collected were reviewed, and a sample peeled off from the damaged part was analyzed to investigate the structure and material of the background layer. The results revealed that the Simhyangsa Temple Buddha statue was an almost empty Dried-lacquer(Hyeopjeo) Buddha statue where wood core had not been framed and inserted in the statue. It was thus observed that considering that the clothes wrinkles clearly remained, the same one as the irregularity of the outer clothes wrinkles, the Dried-lacquer layer was lifted made in an almost complete shape in the process of forming the clay figure as the origin form. The statue was found to be diagonally incised from the top of the head to the back of the neck to remove the clay and wood core. But in other sites, no incision was confirmed. It was observed that on the site of the head where the incision was made, an adhesives(lacquer or paste) was used. In addition, the black eyes were impacted with beads and the ears, hands, bands, and knots were made of wood. These features are identically shown in the Dried-lacquer Amitabha Buddha statue from Seonguksa Temple, known as a work of the late Goryeo dynasty; the Seated Dried-lacquer Buddha statue in Okura Museum of Art in Tokyo, Japan; the Seated Dried-lacquer Amitabha Buddha statue from Jungnimsa Temple, know as a work of the early Joseon dynasty; and the Seated Vairocana Buddha statue in Bulhoesa Temple, the Seated Dried-lacquer Amitabha Buddha and the Seated Dried-lacquer Buddha statue from Silsangsa Temple. The analysis of the back layer demonstrated that the ground layer and the red lacquer were the production of the time. In particular, the bone ash used for the ground layer was also coated for the ground layer of Buddha statues as well as for the production of the lacquerware during the Goryeo dynasty. It was also found that gold mending was conducted more than twice even in modern times and that the layer of the production time was well preserved despite gold mending several times.

  • The human rights of older people have gotten more attention recently in South Korea, a country that is in transition to a super-aged society. This study aimed to systematically review studies on elder abuse and related factors among community-dwelling older adults in South Korea over twenty years (1994-2016). We searched major databases (Riss, DBpia, KISS, KMbase, and PubMed) and identified published studies relevant to the topic. Based on inclusion and exclusion criteria related to study quality, a total of 31 studies were selected for this review. We examined types, measurements, and risk factors of elder abuse as well as study designs in the selected studies, guided by Johannesen's theoretical framework on elder abuse. All of the reviewed studies on elder abuse in Korea were cross-sectional studies, most of which focused on older people living in urban areas, using a non-random sampling method. All of the studies focused on certain types of elder abuse only. Some adopted elder-abuse instruments that were not validated, and others used self-developed instruments without psychometric tests. As for the risk factors of elder abuse in South Korea, the physical and mental health of the victims and aggressors impacted the risk of elder abuse, but general sociodemographic factors such as age, sex, and education were less likely to be related to the risk. In addition, decreasing caregiver burden and building elder-friendly communities are important for the prevention of elder abuse. Needed are further empirical studies on elder abuse with a theoretical framework that gives consideration to the unique sociocultural contexts of Korea. It is also recommended to develop instruments to measure elder abuse reflecting the sociocultural contexts of Korea, and to examine the multi-dimensional risk factors of elder abuse.

  • This study was performed to identify the impact of awareness and educational experiences on cardiopulmonary resuscitation in the ability to execute of cardiopulmonary resuscitation among Korean adults. This study used original data of 2014 Community Health Data Survey. 228,712 participants in this survey were resident in South Korea who is aged 19 or older on July 2014. Participants in this survey were sampled an average of 900 residents(target error ${\pm}3percent$) per community health center of Korea. Data were analyzed by using R 3.1.3 employing chi-squared test, fisher's exact analysis, and logistic regression analysis. Ability to execute CPR was significantly higher in males(3.34 time), higher the education level (1.61 times), the white color occupation (1.14 times), the higher the income level (1.07 times), the higher the education level (0.91 times), non-hypertensive patients (1.12 times), non-diabetic patients (1.16 times), non-dyslipidemic patients (0.86 times), non-stroke patients (0.30 times), CPR education experience group (3.25 times), CPR experience group with manikin-based training (4.30 times), higher subjective health status (1.08 times, 1.16 times) respectively. This study identified that awareness, educational experience, and mannequin-based learning experience of CPR impacted on the ability to execute CPR. Responding to education-related factors could contribute to reducing the rate of out-of-hospital acute cardiac arrest by improving the ability to execute CPR of the general public.

  • Stormwater runoff containing considerable amounts of pollutants such as particulates, organics, nutrients, and heavy metals contaminate natural bodies of water. At present, best management practices (BMP) intended to reduce the volume and treat pollutants from stormwater runoff were devised to serve as cost-effective measures of stormwater management. However, improper design and lack of proper maintenance can lead to degradation of the facility, making it unable to perform its intended function. This study evaluated an infiltration trench (IT) that went through a series of maintenance operations. 41 monitored rainfall events from 2009 to 2016 were used to evaluate the pollutant removal capabilities of the IT. Assessment of the water quality and hydrological data revealed that the inflow volume was the most relative factor affecting the unit pollutant loads (UPL) entering the facility. Seasonal variations also affected the pollutant removal capabilities of the IT. During the summer season, the increased rainfall depths and runoff volumes diminished the pollutant removal efficiency (RE) of the facility due to increased volumes that washed off larger pollutant loads and caused the IT to overflow. Moreover, the system also exhibited reduced pollutant RE for the winter season due to frozen media layers and chemical-related mechanisms impacted by the low winter temperature. Maintenance operations also posed considerable effects of the performance of the IT. During the first two years of operation, the IT exhibited a decrease in pollutant RE due to aging and lack of proper maintenance. However, some events also showed reduced pollutant RE succeeding the maintenance as a result of disturbed sediments that were not removed from the geotextile. Ultimately, the presented effects of maintenance operations in relation to the pollutant RE of the system may lead to the optimization of maintenance schedules and procedures for BMP of same structure.

  • The Five-story Stone Pagoda from the Dongsa-ri Temple Site in Buyeo, dated to early Goyeo Dynasty, is valuable in that it is the southernmost example of the capital Kaesong pagoda style. This pagoda exhibits characteristics of the central Goryeo style featured in the pagodas built in and around the capital Kaesong, such as the diagonally curved section of the support for the cover stone above the upper stereobate. It also shares stylistic affinities with eleventh-century stone pagodas. The ansangmun (elephant eye patterns) in the lower stereobate of the Dongsa-ri Five-story Stone Pagoda resemble those in the pedestal of the Stone Seated Buddha (which was likely repaired in 1028 during the reign of King Hyeonjong), at the Jeongrimsa Temple site in Buyeo. It also reflects elements found in the flagpole supports from the Cheonheungsa Temple site in Cheonan. The sculpting techniques used in these patterns are also similar. Such congruencies suggest that the Dongsa-ri Five-story Stone Pagoda was built in the eleventh century. The Dongsa-ri Temple Site in Buyeo, located near the Geumgang River, served as a principal route for transporting grain-tax during the Goryeo Dynasty. It was also situated along the way to the Goryeo royal temple, Gaetaesa Temple. The geographical significance of the site and the extensive repairs undertaken at Jeongrimsa Temple during the reign of King Hyeonjong (r. 1009-1031) of the Goryeo Dynasty appear to have impacted the production of the Dongsa-ri Five-story Stone Pagoda. The Dongsa-ri Five-story Stone Pagoda also bears stylistic resemblances to the stone pagoda and flagpole supports found at neighboring Cheonheungsa Temple, which is presumed to be related to the establishment of Honggyeongsa (or Honggyeongwon) Temple in 1021 in Cheonan. This indicates the route of the transmission of the Kaesong pagoda style. The Five-story Stone Pagoda from the Dongsa-ri Temple Site pays testimony to the cultural accomplishments of eleventh-century stone artworks in Buyeo and adjacent regions. This pagoda embodies the majestic and assertive aesthetics that define of the Goryeo Dynasty, as do early Goryeo colossal Buddhist sculptures, including the Stone Standing Maitreya Bodhisattva at Daejosa Temple in Buyeo, the Stone Standing Buddha Triad at Gaetaesa Temple in Nonsan, and the Stone Standing Maitreya Bodhisattva at Gwanchoksa Temple in Nonsan. All of these bear similarities to the massive stone lantern and pagoda at Hyeonhwasa Temple in the capital Kaesong. The production of the light, sleek, sharp, and sophisticated Dongsa-ri Five-story Stone Pagoda is presumed to reflect the maturity of the cultural competence of the people in Dongsa-ri, Buyeo under the influence of Buddhist culture from the capital Kaesong during the eleventh century, a time marked by active cultural exchanges among regions.
