To investigate the effects of C. E. P. A(2-chloroethyl phosphonic acid) on the ripening of tobacco leaf, the effects on the yield and quality of leaf tobacco, this experiments were carried out during the period of from 1970 to 1971 at tobacco experiment station, Sosa, Korea and 3 locations. The results are summarized as follows. 1. The higher the C. E. P. A concentration was, the more the leaf ripening was accelerated. During the period from 3 to 4 days after treatment, the differences of leaf ripening among levels were prominent. 2. Treatment with C. E. P. A only on the upper surface of the tobacco leaf, accelerated the ripening of that particular part treated, but not apparently the other parts of leaf. 3. Distinctive acceleration of leaf ripening was, obserbed in the fully develope1lower leans, however, the upper leaves were indistinctive. 4. The higher C. E. P. A concentration was, the more the effect of ripening acceleration was. But the yield was reduced over 900ppm because of the low of growth of leaves and the reduced yield was 90% at the 3, 000ppm. So the proper concentration was regarded as 900ppm. 5. In the view point of the days of C. E. P. A ripening acceleration, it was shortened one days at 100 ppm, three days at 300ppm, three days at 450ppm, four days at 900ppm, seven days at 3, 000ppm. 6. In the point of curing process, it was possible that the curing time and fuel was reduced 29% and 45% respectively in the C. E. P. A treatment than the check. 7. Therefore, if it is treated the C. E. P. A at 900ppm in the tobacco cultivation, the quality shall be increased 13.5% and the price shall be increased 12% in the 10 Are. In the point of subsidiary affect, it is possible that the C. E. P. A ripening acceleration is shortened about 7 days at 3, 00ppm and curing time is shortened about 24 hours.

With the development of blockchain technology, play-to-earn (P2E) games, one of the decentralized applications (dApps), are receiving great social attention. P2E games are positively evaluated as areas with high growth potential based on blockchain technology, and at the same time, they are negatively evaluated as speculative as people can cash P2E game items in the form of cryptocurrency. In this situation, the purpose of this study is to investigate factors affecting the intention to use P2E games. Along with the discussion of hedonic system adoption, we consider the factors with perceived enjoyment, economic incentive, and social influence. In order to verify our research model, data were collected from 350 adults with P2E game experience or recognition, and a structural equation model was carried out. The analysis results find that perceived enjoyment and subjective norm have a significant positive effect on the intention to use P2E games, and economic incentive does not have a significant effect. In addition, peer influence and external influence have a significant positive effect on subjective norm. Drawing on these findings, we present several academic and practical implications for future research.

Let E be a free product of a finite number of cyclic groups, and S a normal subgroup of E such that $$E/S{\sim_=}G$$ is finite. For a prime p, $\hat{S}=S/S^{\prime}S^p$ may be regarded as an $F_pG$-module via conjugation in E. The aim of this article is to prove that $\hat{S}$ is decomposable into two indecomposable modules for finite elementary abelian p-groups G.

This study proposes the O P E N Triad framework as a future set of tools and perspectives for individual members and institutes to further their professional and academic potential as well as prospect and vitalize the future of the Korean Clothing and Textiles discipline through a global perspective. The millennial generation desires On-demand, Personal, Engaging, and Networked (O P E N) experiences effecting cultural change for creative and influential interaction in transactions, communication, and education. O P E N Individuals offers a WebSphere model as a holistic learning system that has a synergizing value of education across academic courses, industries, and cultures. Through a digitalized and virtualized class, it complements relevant technologies already familiar to the student population. By employing environmental scanning approaches, the most influential and viable future global issues related to the clothing and textiles discipline are identified and dialogued within O P E N Institutes. For future clothing and textiles institutes, this scanning allows them to be open to new ideas, to focus on inter-engagements, to collaborate among individuals, to associate as a part of web of people, organizations, and ideas, to personalize an institutes curricula, and to dialogue generative knowledge. O P E N Industries reveals three dominant future issues that cross academia and industry, sustainability, supply chain management, and social networking. In-depth interviews with U.S. industry experts identified interdependent gaps in global consumer experience practices and suggested the following gaps as future research areas: a standardized business model to the entrepreneurial model, strategic management to a sustainable competitive advantage, standardized to differentiated products, services and operations, market segmentation to global consumer clusters, business-driven marketplaces to consumer-engaged marketspaces, and excellent services to optimal experience. This O P E N Triad framework empowers millennial students, universities, and industries to anticipate and prepare for a radically changing world.

Recently, pre-engineering building (P.E.B.) systematic frames are increasingly being used in steel factory buildings, but almost of the related techniques are dependent on the engineering program (e.g, MBS, LTI), which is usually imported from other countries. These are designed under the AISC-ASD because at present there is no Korean design code for P.E.B. frames. Also, there are few studies onbehaviour and we need to develop the element techniques by using H-shaped components.In particular, there is a tendency towards overestimated design because column-rafter connections have been designed with extended end plate type joint, which is treated asrigid joint,so structural examinations are needed. Therefore, this study represents a basic step in ascertaining the application of P.E.B. systematic frames by using H-shaped column-rafter connectionwith flush type end plate. Its structural performance is compared with that of existing extended type joint using a structural performance test. The structural behaviour of specimen was understood qualitatively and the possibility of application (e.g, design aid charts) of semi-connection (flush type) with H-shaped column-rafter was determined.

Effects of varied dietary energy densities on immune response and performance of Muzzafarnagari lambs were ascertained in a 180-d study. Animals (n = 24), in three groups, were fed diets providing 100% (100E), 80% (80E) or 70% (70E) of their metabolizable energy requirement. Mean nutrient digestibilities varied significantly among treatments. Nitrogen intake was lower (p<0.01) in the 70E. Nitrogen retention, was reduced (p<0.001) in 80E and 70E vs 100E. The average daily gain (p<0.001) was $47.01{\pm}4.23$, $13.54{\pm}1.72$ and $-16.67{\pm}8.24$ g for 100E, 80E and 70E, respectively. Hemoglobin concentration, haematocrit, total and differential leukocyte counts were lower (p<0.001) for 80E and 70E than for 100E with a similar trend (p<0.05) for serum glucose and total protein. Serum cortisol was reduced (p<0.001) with decreased energy availability. Antibody titre to Brucella abortus S19 showed an initial reduction in 80E and 70E vs 100E. Delayed-type hypersensitivity response was lower (p<0.001) in 80E and 70E vs 100E, accompanying a lower (p<0.001) nitric oxide production by the peripheral lymphocytes. It is concluded that the reduced dietary energy density significantly affects the growth performance and immune response of lambs.

Purpose : The purpose of this study was to analyze setter toss motion kinematically according to toss types. Method : Dependent variables were elapsed time, vertical displacement of the body center, the projected speed of the ball, and differences of the joint angle to the target for four setters positioning. Result : There was no significant difference in the time but the ball contact time was shorter when the toss distance of P3 was longer. There was significant difference in the vertical displacement of COM (p<.05). The vertical displacement of COM showed that the vertical movement gradually decreased when the quick distance was longer. The vertical displacement of COM was difference (p<.05), also there was difference of the ball speed (p<.001) at the Release point(E4). There was significant difference in the knee joint angle at a certain moment among the Release(E4) and Landing point(E5)(p<.05). The hip joint was significant difference among the Apex(E2), Ball Touch(E3), Release(E4), and the Landing point(E5) on the surface(E2, E3, E4 p<.05; E5 p<.005). The shoulder angle was significant difference among the Ball Touch(E3), Release(E4) and the Landing point(E5) on the surface(E3, E4 p<.05; E5 p<.001). The elbow was significant difference in the Apex(E2) (p<.05). The wrist was significant difference in the Release(E4) (p<.05). Conclusion : If we find the clue to expect the direction of the setter's ball, we have to fine the clues in the Apex(E2) that hip join and elbow, Ball Touch(E3) that hip joint and shoulder joint, Release(E4) that wrist, elbow, hip joint, and knee joint.

We have completed a study to measure the contents of glucose, BUN, creatinine. LDH, and T-protein with respect to a fatigued condition in the bloods of rats which a constant swimming is loaded and to measure the maximun swimming time of mice The test has been carried out as a part of the basic study on the efficacy of B. E. P. (Biological Energy Projector) for emitting a light energy having a specific wavelength out of far-infrared rays. As a result. We have reached the following conclusions: 1. At testing of mice's maximun swimming time, all of B.E.P.(2. 4. 8. 24hrs) treated group have been increased in comparison with the control group, but only 24hrs-B.E.P. treated group significantly increased during 4 weeks. 2. The contents of glucose, BUN. creatinine, LDH, and T-protein measured immediately after the swimming of mice have been distinctly changed but not been significantly changed at their increase and decrease in comparison with the control group. 3. At 3rd day out of the swimming loading, the contents of glucose in the blood serum of the white rat have been distinctly increased in comparison with the control group. And 24hrs-B.E.P treated group surpassed 8hrs-B.E.P. treated group. 4. At 1st and 3rd day, the contents of creatinine in the blood serum of the white rat have been distinctly increased at B.E.P. (8, 24hrs) treated groups in comparison with the control group and have been recovered to the condition of the normal group. 5. After three days, the contents of BUN in the blood serum of the white rat have been significantly decreased in B.E.P.(8, 24hrs) treated groups at 3rd day in comparison with the control group and have been recovered to the condition of the normal group. 6. The contents of LDH in the blood serum of the white rat have been decreased in B.E.P.(8, 24hrs) treated groups at 3rd day in comparison with the control group, in particular 24hrs-B.E.P. treated group has been decreased distinctly than the normal group. 7. The contents of T-protein in the blood serum of the white rat have been distinctly increased in B.E.P. (8, 24hrs) treated groups at 3rd day in comparison with the control and normal group. As the above results, it has been proved that the execise of mice and the fatigue metabolism of rats were influenced by the light energy emitted the B.E.P., and it has been also proved that the external stimulation could be used as a preferable stimulative factor for the biological metabolism. If the clinical training and study are positively achieved, the B.E.P. would be used as curative means and preventive measures for helping human body.

Let K be a number field and fix a prime number $p$. For any set S of primes of K, we here say that an elliptic curve E over K has S-reduction if E has bad reduction only at the primes of S. There exists the set $B_{K,p}$ of primes of K satisfying that any elliptic curve over K with $B_{K,p}$-reduction has no $p$-torsion points under certain conditions. The first aim of this paper is to construct elliptic curves over K with $B_{K,p}$-reduction and a $p$-torsion point. The action of the absolute Galois group on the $p$-torsion subgroup of E gives its associated Galois representation $\bar{\rho}_{E,p}$ modulo $p$. We also study the irreducibility and surjectivity of $\bar{\rho}_{E,p}$ for semistable elliptic curves with $B_{K,p}$-reduction.
