Mongolia as a land-locked country, has tried to diversify its foreign trade with European and Asian countries. Recently continual price rise of mineral resources also helps Mongolia have chances to gain her trading partners. Nevertheless, regulations and barriers to exports of Mongolian mineral resources in China and Russia, which are transit countries, are complex and complicated in border crossing and transshipment procedures for transit transport. This paper discusses problems and barriers to economic and efficient logistics systems and transit transport of Mongolian mineral resources, and addresses a proposal of international intermodal transport corridors for improving transit transport, and suggests international cooperation, by applying transit rights of land-locked country. Specifically, it is necessary for Mongolia to search for other international intermodal corridors besides the corridor through the port of Tianjin. It is needed to build an international organization for discussion of affirmation of logistics equipments and improvement of transit procedure in border crossing, and to raise financial feasibility in building a new intermodal corridor.

This study is a research that investigated organization of case management practice at a mental health center. For organization research of case management practice, this study applied the research method of Institutional Ethnography, and analyzed 'work knowledge' and 'texts' data which were obtained through field work that lasted 3 months with 11 study participants. The analysis is not interpretation of the researcher, but it is work that assembles 'work knowledge' of field workers until they reach discovering institutions that organize case management practice. As a result of this study, case management practice of the mental health center was being standardized as 'a service that is biased towards symptom management without comprehensive and continual resources links' by new public management theory, bio-medicine discussion, 'standardization policy', 'treatment rate improvement policy', 'performance-based budget system', 'performance evaluation system' and 'continual linkage policy', mediating texts. This is a different outcome from usefulness of case management that is claimed to support politically.

The numerous investments have been introduced to design and assess mixing zone characteristics of wastewater discharges to the ocean. Specially It strive to meet water quality standard for persistent and bio-accumulative chemical contaminants at the point of discharge through continual improvement pollution prevention measures and other voluntary measures in the developed country. The goals that of this paper are to emphasize the regulatory mixing zone is defined as an allocated impact zone where the numeric water quality criteria may be exceeded as long as acutely toxic conditions are prevent. Furthermore, mixing zones be limited to an area or volume as small as practicable that with not interfere with the designated uses or the established community of aquatic life in the segment for which the uses are designated and the shape be a simple configuration that is easy to locate in the body of water and avoids impingement on biologically important areas and the shore hugging plumes should be avoided This results should be used with caution in evaluation the mixing zone characteristics of a discharge and only in conjunction with information from the effective marine outfall design as well as for the sound harbour design. Thus the numerical investigation using CORMIX has been performed to show the regulatory mixing zone in the near and far field of the marine outfall.

A Wireless Access for Vehicular Environment (WAVE) system based on Orthogonal Frequency Division Multiplexing (OFDM) is made for vehicle to vehicle wireless communications. The physical layer standard of the WAVE system is very similar to that of the IEEE802.11a wireless local area network (WLAN). Therefore, the performance of the WAVE system is degraded by continual channel variation in the WAVE multipath fading channels after starting initial channel estimation. In this paper, we research the performance improvement of equalization in 64 Quadrature Amplitude Modulation (QAM) transmission in WAVE environment. The proposed algorithms use the training sequence and the midamble sequence which is used for fast channel variation such as WAVE environments. Additionally, various interpolation methods are also used for the channel tracking.

The muscles relating to movement of painful low back was analyzed kinematically, by method of applying elastic tapes and putting non-elastic tapes on muscles involving those movements which cause pain and limitation of range of motion (ROM) in low back and trunk. Taping therapy which is effective for improvement of painful low back and which is supposed to facilitate the total and continual movement based on the postural reflexes will be presented in this paper. Fifty cases who had painful low back were investigated. Patients with painful low back were at first asked pain point and direction of painful movement, and then tested the muscles which are cause of those pain and limited motion. Before attaching tape, all subjects were divided into two groups, flexor pattern and extensor pattern, according to direction of increasing pain. Elastic tapes were applied from origin to insertion of objective muscles and non-elastic tapes were put on effective points of the muscles which were associated with respect to pain and limited ROM. As a result of this study, all subjects with low back pain significantly improved in pain and ROM at the low back. The longest treatment duration group for the low back pain cases was herniated lumbar disc(10.4 days) group. Low back pain have been treated by so many ways. muscles factor should be emphasized to be distinguish1y important to reduce low back pain. The muscles relating to make directly painful motion in low back and trunk should be confirmed by means of taping and painful motion should be analyzed by point of view of postural reflexes.

Tunnel sections on the expressway are different from rest of sections on the expressway in terms of velocity, the number of passing cars, and vehicle density which, in particular, affect drivers' behavior before and after drivers pass through the tunnel. However, literature review reveals that former studies are too focused on quantitative indicator to consider qualitative aspects. Thus, this study tried to find out qualitative factors affecting speed reduction in tunnel sections based on questionnaire surveys and its analysis in tunnel sections selected by taking consideration of diverse conditions. Analysis showed that factors concerning tunnel configuration (lane width, shoulder width, and tunnel length) related to very long tunnels increasingly popular recently had some effects on reduced speed inside of tunnels. It appeared that visual environment such as visibility of tunnel entrance had an impact in speed reduction and vehicle speed tended to change according to lighting illumination level inside of tunnels. It is expected that continual investment would be made in technological development related to expressway tunnel design and service improvement based on this study.

Background: Construction activity has made considerable breakthroughs in the past two decades on the back of increases in development activities, government policies, and public demand. At the same time, occupational health and safety issues have become a major concern to construction organizations. The unsatisfactory safety performance of the construction industry has always been highlighted since the safety management system is neglected area and not implemented systematically in Indian construction organizations. Due to a lack of enforcement of the applicable legislation, most of the construction organizations are forced to opt for the implementation of Occupational Health Safety Assessment Series (OHSAS) 18001 to improve safety performance. Methods: In order to better understand factors influencing the implementation of OHSAS 18001, an interpretive structural modeling approach has been applied and the factors have been classified using matrice d'impacts croises-multiplication $appliqu{\acute{e}}$ a un classement (MICMAC) analysis. The study proposes the underlying theoretical framework to identify factors and to help management of Indian construction organizations to understand the interaction among factors influencing in implementation of OHSAS 18001. Results: Safety culture, continual improvement, morale of employees, and safety training have been identified as dependent variables. Safety performance, sustainable construction, and conducive working environment have been identified as linkage variables. Management commitment and safety policy have been identified as the driver variables. Conclusion: Management commitment has the maximum driving power and the most influential factor is safety policy, which states clearly the commitment of top management towards occupational safety and health.
