Nepal's role in the expansion of Mahayana Buddhism beyond the Himalaya is very significant. Nepal became the center of Mahayana Buddhism after the Muslim invasion of Nalanda Mahavihara in the 1199 A.D., which she maintained almost for 300 years. During this period, Nepal had produced a large number of profound Buddhist scholars. Most of them were the teachers of eminent Tibetan Buddhists. Some of the Nepalese Gurus also has continued lineage in Tibet until now. During that time, every Tibetan had desire to go to Nepal for higher Buddhist learning. As a matter of fact, many Tibetans made arduous journey across the Himalaya to fulfill the dream. Tibetan studied various forms of tantra, precepts, logic, doctrine, Sutra, Sadhana, Doha, Charyagiti, meditation etc. under direct supervision of Nepalese teachers. Great Tibetan scholars such as Marpa, Rwa Lo, Chag Lo, Khon phu ba, Klog Lo, Gos Lo, and others were the product of Nepal's scholarly tradition. They have significant place in the history of Tibet. Nepalese scholars also frequently visited Tibet where they taught Buddhism in various monasteries. They also had major role in propagating tantra in Tibet. Tibetans firmly believe that it is not possible to attain enlightenment without practicing tantra. The contribution of Nepalese scholars was so profound that Tibet produced many eminent scholars who developed scholastic tradition in Tibet. But after 14th century, Nepal's scholarly tradition ceased to continue. Then after, Tibetans started to call them 'the dull'.
This paper describes the observed behavior in the direct shear test on decomposed granite soil having the complicate engineering properties at various different levels of factors. The objectives of this study were to investigate the characteristics of the decomposed granite soil under controlled various moisture content, dry density, strain rate and soaking which give influence to the shear strength. The results were summarized as follows; 1. The shear strength was decreased remarkably with the increasing of moisture contents of A and B soil were 5-10% and 15-20% respectively. 2. Cohesion and angle of internal friction were decreased with the increasing of moisture content and increased with the increasing of dry density. 3. The shear strength was increased with the increasing of normal stress and volume change was decreased on the whole. The shear strength was generally increased with the increasing of the strain rate. 4. As dry density increases, A-soil shows the progressive failure and the decrease of volume change while B-soil shows the initial failure and the increase of volume change. 5. The relationships between the soaked and unsoaked specimens were as follows ; ${\tau}_f=0.1009+1.026{{\tau}_f}^*$ (A-soil), ${\tau}_f=0.1586+0.8005{{\tau}_f}^*$ (B-soil) 6. Angle of internal friction of the direct shear test shows larger value than that of the triaxial compression test. All effective stress path was nearly similar.
The purposes of this study was to investigate job related attitudes of emotional labors working at call centers in Korea. The attitudinal variables were burnout, psychological capital and turnover intention with job characteristics as the independent variables. In addition, leadership behaviors of the superiors, self leadership behavior in particular, was incorporated to see if it has any bearing on these relationship as moderating variable. Data has been collected from 543 respondents for this study using questionnaire method. The survey for the actual analysis of the research was done and analyzed with the employees who work for contact centers in Seoul, Busan, and Gwangju, Korea. The survey was done for 24 days from November, 2016 through December, 2016. * The following study results were revealed: First, the job characteristics does not have direct positive effect on turnover intentions. Second, the job characteristics were related positively to job burnout. Third, the job burnout does mediate the relationship between job characteristics and turnover intentions. Lastly, results of research on the moderating effect of self leadership in relationships between emotional labor, job burnout, psychological capital and turnover intention show that super leadership has only a limited regulatory effect between job characteristics and turnover intention.
A submodule N of a module M is called ${\mathcal{S}}$-closed (in M) if M/N is nonsingular. It is well-known that the class Closed of short exact sequences determined by closed submodules is a proper class in the sense of Buchsbaum. However, the class $\mathcal{S}-Closed$ of short exact sequences determined by $\mathcal{S}$-closed submodules need not be a proper class. In the first part of the paper, we describe the smallest proper class ${\langle}\mathcal{S-Closed}{\rangle}$ containing $\mathcal{S-Closed}$ in terms of $\mathcal{S}$-closed submodules. We show that this class coincides with the proper classes projectively generated by Goldie torsion modules and coprojectively generated by nonsingular modules. Moreover, for a right nonsingular ring R, it coincides with the proper class generated by neat submodules if and only if R is a right SI-ring. In abelian groups, the elements of this class are exactly torsionsplitting. In the second part, coprojective modules of this class which we call ec-flat modules are also investigated. We prove that injective modules are ec-flat if and only if each injective hull of a Goldie torsion module is projective if and only if every Goldie torsion module embeds in a projective module. For a left Noetherian right nonsingular ring R of which the identity element is a sum of orthogonal primitive idempotents, we prove that the class ${\langle}\mathcal{S-Closed}{\rangle}$ coincides with the class of pure-exact sequences of modules if and only if R is a two-sided hereditary, two-sided $\mathcal{CS}$-ring and every singular right module is a direct sum of finitely presented modules.

Land use types within a watershed closely are related with the water quality characteristics of receiving water bodies. Despite of a numerous studies suggesting a strong relationship between water quality and land use, there have been increasing concerns about the geographical variation and a lack of spatial integration in that relationship, which are essential to implementing these findings into land use planning and management. In the meantime, edges mediate the material flux between adjacent systems. This mediating effect of edges is strongly related to the complexity of their shapes. Land use activities within a watershed have a direct impact on the water quality of adjacent aquatic systems, and hydrological processes carry residuals from watershed into adjacent aquatic ecosystems through the edges. Therefore, the geometry of reservoirs theoretically affects the relationship between land uses in the watershed and the quality of receiving bodies of water. In this light, this study integrates the geo-spatial dimensions of land uses in the watershed using GIS and landscape indices in order to explore the relationship between land uses and water quality. Water quality characteristics, land uses and geometry of 133 randomly sampled reservoirs were correlated, based on buffer zones and types of reservoirs. The findings showed that land uses, particularly urban land uses, significantly affect water quality characteristics including BOD, COD, TN and TP, and geometry of reservoirs reduces the concentration of pollutant and nutrients in reservoirs. One of results indicates that the relationship between land use and water quality and effects of spatial dimension may vary with types of reservoirs and pollutants. These results suggest that lakeshore areas are important, particularly for TN reduction and call for a caution to land use activities nearby shoreline areas for sustaining better water quality.
Mobile map services using PDA are prevailing because of the rapid developments of techniques of the internet and handhold devices recently. While the volume of spatial data is tremendous and the spatial operations are time-intensive, the PDA has small size memory and a low performance processor. Therefore, the spatial index for PDA should be small size and efficiently filter out the candidate objects of spatial operation as well. This paper proposes a spatial index far PDA called MHF(Multilevel Hashing File). The MHF has simple structure for storage efficiency and uses a hashing technique, which is direct search method, for search efficiency. This paper also designs a compression technique for MBR. which occupies almost 80% of index data in the two dimensional case. We call it HMBR. Although the HMBR technique reduces the MB\ulcorner size to almost a third, it shows good filtering efficiency because of no information loss by quantization in case of small objects that occupy a major portion. Our experimental tests show that the proposed MHF index using HMBR technique is appropriate for PDA in terms of the size of index, the Number of MBR comparisons, the filtering efficiency and the execution time of spatial operations.
This paper aims to identify the class characteristics of tenants. To this end Patnaik's model is selected, because this model is most reasonable for sorting class structures of tenants. In his Model, "labor-exploitation criterion" is the main criterion for identifying class status. According to this criterion, there are five rural classes i.e. landlord, rich peasant, middle peasant, poor peasant, and full-time laborer. "Net labor ratio" is used for this purpose as empirical data handling. Net labor ratio is a ratio of net labor hired in to family labor, if hired in labor is more then this ratio is positive, and if hired out labor is more then the ratio is negative. Hired in and hired out labor includes not only direct labor but indirect labor such as labor employment or sales through rent. The results of this study are summarized as First, almost all tenants and owner cultivators are of the middle peasant class. Second, there are no rich peasant among the tenants, but 5% of owner cultivators are rich peasants, and 10% of tenants are poor peasants, owner cultivators are 1%. Third, the net: labor ratio of tenants is -0.211, and that of owners is 0.143. There are differences between tenants and owner cultivators even if land is much the same, and owner cultivators net labor ratio is positive except in the land size of 0.3-0.5ha, but that of the tenants' is negative. Fourth, proto-labor poor peasants earned 25% of income from labor, compared with under 10% of proto-tenant poor passant's. Rent to income ratio is almost 60% of proto-tenant, 27% of proto-labor among poor peasants.
Status survey on short-term agricultural machinery rental business was conducted to provide basic data for effective and sustainable implementation of the rental system. Selected survey samples were 34 rental management institutions such as city and county level government offices and agricultural technology development centers, and Primary Agricultural Cooperatives. Survey was conducted through mailing of questionnaire papers and direct interviews with the officers in charge of the agricultural machinery short-term rental management. Number of agricultural machinery retained by the 34 management institutions for the machinery rental business was 3,699, and numbers of the machinery were 1630 for upland crops, 929 for rice, 542 for orchard farming, 274 for animal husbandry, and 324 for common use. Regarding size of warehouse for rental agricultural machinery, 50% of the institutes were less than 660 $m^2$, 26.5% were greater than 993 $m^2$, and 23.5% were between 663 and 990 $m^2$. Institutes maintaining machinery washing facilities were only 10 (29%) among the 34 rental management institutions. Agricultural machinery rental business was advertised to farmers by 91% of the institutes, and the methods were leaflet (35.2%), village broadcasting (26.5%), call-up education (23.6%), and TV and radio (14.7%). Major contents of the advertisement were rental procedure (52.9%), rental machinery (26.5%), and rental cost (20.6%).
Objectives: The purpose of the study was to examined the demand for the change in Korean dental hygiene curriculum. This study compared the dental hygiene curriculum of domestic and overseas university and tired to provide the basic data for the development of standard curriculum that meets the education policy changes. Methods: Data were obtained from a cross-sectional survey of 1,192 participants including dental hygiene professors, dental hygienists and students. Data were collected by mail, telephone call from the professors and research assistants, email, and direct visit from June 10 to August 10, 2013. The questionnaire consisted of 4 questions of general characteristics of the subjects and 13 questions of dental hygiene curriculum. Results: The professors answered the development of integrated dental hygiene curriculum as the first priority(48.9%) and dental hygienists(51.6%) and students(42.6%) chose the development of new dental hygiene curriculum(p<0.001). In the analysis of validity of dental hygiene curriculum, the professors gave 3.29 to the validity of evaluation for basic job performance, and the clinical dental hygienists and the students gave 3.05 and 3.26 points, respectively(p<0.001). In relation to the necessity of the change of the dental hygiene curriculums, the professors gave 4.17 points which implied that curriculum change is the most important and necessary thing to do. The clinical dental hygienists and the students gave 3.90 and 3.47 points, respectively(p<0.001). Conclusions: The above-mentioned findings suggest that the revision of the current Korean dental hygiene curriculums is required. Therefore organizations related to dental hygiene including professor association and Korean Dental Hygienists Association should carefully rebuild the curriculum to improve the competency of dental hygienists. They should take the initiative in the development of a standardized curriculum.

Objectives: The aim of this study was to investigate the curriculum of Chuna manual medicine (CMM)-related subjects in oriental medicine college and to let CMM have opportunities to develope current curriculum and basic circumstance for CMM. Methods: Questionnaire was obtained from 11 oriental medicine college and 1 school of Korean medicine, Pusan National University, bye-mail. If there was any insufficient information from response, we asked more information by direct call. Results and Conclusions: The findings from our study can be summarized as follows: 1. There are three CMM-related subjects, CMM, Oriental Rehabilitation Medicine (ORM) and Neuromusculoskeletology(NMS). All curriculums of 8 colleges belonged to classification I have CMM and DRM courses. Curriculums of 4 colleges belonged to classification II, have ORM or NMS course without CMM course. 2. 10 colleges of 11 ones which have ORM course, have major compulsory courses, 1 college has a major optional course. 5 colleges of 8 ones which have CMM course, have major compulsory courses, 3 colleges have major optional courses. 2 colleges have only part-time lecturers for CMM course, other 2 college have cooperation of specialized professors and part-time lecturers, another 8 colleges have only specialized professors. 3. Most CMM-related subjects is teached at 3 or 4 grade of medical course. The units taken for CMM-related subjects is minimum 4 units to maximum 8 units in total about 160 units. 4. Total class hour for CMM-related subjects is minimum 120 hours to maximum 225 hours, and practice hours is about minimum 30 hours to maximum 75 hours. 5. The systematic regulation and financial support is needed for patients to get the best CMM treatment, because the present curriculum of CMM is insufficient for carrying out the best manual therapy for patients.
