A Systematic Observation of Youth Amateur Volleyball Coaches Behaviours
( Mesquita Isabel ),( Sobrinho Antonio ),( Rosado Antonio ),( Pereira Felismina ),( Milistetd Michel ) 한국스포츠정책과학원(구 한국스포츠개발원) 2008 International Journal of Applied Sports Sciences Vol.20 No.2
The purpose of this study was to examine the coaching behaviours of youth amateur volleyball coaches within the practice environment, through the Arizona State University Instrument (ASUOI), making a contribution to the expanding empirical database. Moreover, we intend to compare the instructional profilesbetween youth amateur coaches and earlier research that wasdone using ASUOI, particularly with top-level professional coaches. The participants for this study were eleven Portuguese male youth volleyball coaches who coach amateur teams on the club setting from under 14 until under 18. A total of 6401 recorded behaviours were observed from eleven training sessions. The results show a predominance of instructional behaviours like pre-instruction, concurrent instruction and post instruction (35.94 %). However, it seems consistent to assume from the coaches observed, that they show a lower use of instructional and praise behaviours compared with that of top-level professional coaches as verified in earlier studies. Additionally, the findings on the use of first names, questioning and modelling, important strategies to promote active learning and meaningful affective relationships, showed a reduced use. The results highlighted the contextual and specific nature of the coaching process, which emphasized the need for a deeper analysis concerning the coaching behaviours in relation to the substantive content demonstrated by the coach as in relation to the type of practice.

Morus nigra has been used to relieve pain in Brazilian folk medicine. This study was conducted to establish the antinociceptive properties of dichloromethane extract from leaves of M. nigra. The formalin, hot plate, and tail immersion tests as well as acetic acid-induced writhing were used to investigate the antinociceptive activity in mice. The extract at test doses of 100 and 300mg/kg, p.o. clearly demonstrated antinociceptive activity in all tests. The extract administered at 300mg/kg, p.o. had a stronger antinociceptive effect than indomethacin (5mg/kg, p.o.) and morphine (10mg/kg, p.o.), which supports previous claims for its traditional use.
Prospects for a New Regional Order in Northeast Asia
( Bruce Bueno De Mesquita ),( Chae Han Kim ) 한국국방연구원 1991 The Korean Journal of Defense Analysis Vol.3 No.2
An expected utility model is used to predict the likely structure of security arrangements in the Northeast Asia region and to evaluate the prospects for cross-recognition and South Korean entry into the United Nations as a full member. We find that the Soviet Union, knowing it will be difficult to form such a security and cooperation structure as the CSCE in a short period of time, will try to conclude a bilateral friendship and cooperation treaty .with each Northeast Asian nation. The United States is not expected to change its Northeast Asia policy. We found that even if the Soviets would drop their stance on multilateral negotiations in Northeast Asia and de-nuclearization of the peninsula, this would not alter the structure of the newly emerging regional order in Northeast Asia. The United States cannot afford the luxury of a unilateral withdrawal from the security negotiation process. Its position is pivotal. The Soviet Union and China are expected to support Seoul`s bid to enter the United Nations. We find that Moscow and Beijing perceive the expected cost of defecting from one of the Koreas to exceed the expected benefit of helping the other Korea. Neither is likely to veto a South Korean entry because each perceives greater benefits than costs from cooperating with the South`s entry. We also forecast Korean cross-recognition. Finally, the predicted new regional order in Northeast Asia favors a weak conference setting that includes both Koreas. The weak conference setting is not expected to have a formalized status such as the CSCE. A Soviet- supported Asian collective security system is unlikely within the current political context. We expect progress toward the expansion of bilateral relations into all pairs of countries concerned.
PWSCC and System Engineering Development of Internal Inspection and Maintenance Methodology for RCS
Abdallah, Khaled Atya Ahmed,Mesquita, Patricia Alves Franca de,Yusoff, Norashila,Nam, GungIhn,Jung, JaeCheon,Lee, YoungKwan The Korean Society of Systems Engineering 2016 시스템엔지니어링학술지 Vol.12 No.1
Due to safety of the plant, it became very clear the importance of study occurrence reactor coolant system (RCS) issues specially the primary water stress corrosion cracking (PWSCC). The Systems Engineering (SE) approach is characterized by the application of a structured engineering methodology for the design of a complex system or component. Robotic devices have been used for internal inspection, maintenance and performing remote welding and inspection in high-radiation areas. In this paper, PWSCC overview and inlay and over lay welding methodology introduced, concept of robotic device that can be inserted into the piping via Steam Generator (SG) main way to access to primary piping of pressurized water reactor (PWR) is developed based on SE methodology. A 3D model of the inspection system was developed along with the APR1400 (Advanced Power Reactor)reactor coolant systems (RCS) and internals with virtual 3D simulation of the operation for visualization to prove the validity of the concept.
