대부분의 게임 디자이너들은 베타버전이 나와 제품에 대한 품질 확인 문의가 생길 때까지 제품에 대한 피드백을 받지 않는다. QA 테스터는 게임 제작의 관행을 깨기 위해 노력하고 있다. 특히 QA 테스터는 버그와 밸런스 문제를 찾고 주요 게임 플레이 문제까지도 찾아낸다. 하지만 이들이 디자인 문제에 대해 피드백을 준다고 하더라도 제품은 몇 달 이내의 빠른 시간 내에 선적되어야 하기 때문에 이 문제를 모두 해결하려면 시간이 너무 늦어진다.

1972년 7월 25일 주우고무는 당사(Fuji) 스피이드웨이에서 영던로프의 "토오탈모빌리티타이어"의 공개실험을 행했다(주:73년 8월호 본타이어 고무지33p로 개보). 그런데 그후 동타이어의 기술적 진보에 의한 더욱 안전한 타이어가 이의 피랠리이사와의 협동개발로 행해진다고 전해지고 있었다. 이것은 로오드데스트지 등의 자료에 의거 해석된 것이다.

This experiment was conducted to evaluate the effect of fruit quality, ethylene evoluoon and storage in apple 'Tsugaru' as influenced by aminoethoxyvinylglycine(AVG) and several surfactants. When treated with AVG+Silwet L-77, there were few significant differences in soluble solid and acidity as compared with control, but dichlorprop treatment significantly increased in soluble solid and decreased in acidity. Color development was decreased when treated with AVG+Silwet L-77. AVG+Silwet L-77 treatment decreased in ethylene evolution, and increased in storage. It can be concluded that fruit can be left in trees longer and still maintain storage, and more fruit is able to go to fresh market into long-term storage, which increase the market-ability of apple.

This paper describes the control of a solenoid valve of ESC(Electronic Stability Control) with hydraulic modulator in braking system. ESC ECU(Electronic Control Unit) to control the high-frequency control and slope control method was applied, the surge pressure and EMI(electromagnetic interference) reduction characteristics were studied. The stage of ECU output was added the slope shaping function to reduce electromagnetic emission at higher frequencies. Measurements show that this high frequency ECU manages to reduce the surge pressure and electromagnetic emission by the control of solenoid valve. In conclusion, by using the results of this study for the high frequency ECU control, we could expect enhancement of braking system performance.

The development of automated container terminal has been a hot issue for recent years. It's very natural because it's very important how many containers, how soon, and how precisely a container terminal can treat. A crane treats a very heavy container, maybe, no less than 20∼40 tons, thus most cranes use ropes to take up and land containers. But rope causes the sway of a container and this phenomenon is not avoided. On the ground of this, in most case how much skillful a driver is may affect the productivity of a yard or quay crane. Thus many researches have been concentrated on the development of the control algorithm for a crane which may be useful and robust enough to drive a crane without any human driver. Authors of this paper also are interested in this kind of research but we have been much more interested for years in the development of a mechanical structure which may cause much less sway than the existing cranes do. In this paper, we may introduce the basic structure of the developed anti-sway system.

"Duck Hunting" is the most psychological play with unique structure written by Aleksandr Vampilov. The play describes protagonist hero's furious behavior with psychological instability, therefore, this play tends to be recognized as serious and complicated one. After the death of Vampilov, "Duck Hunting" was reproduced as a film, titled as "Vacation in September." This study is designed to shed light on the play's psychological-dramatic factors by focusing on the structure of narrative and spatial-temporal objet. Also, this study compared the screenshots of the play with their textual meanings, then concentrated on main character's psychological features. By focusing on protagonist hero's mind, this study tries to look into the features of the play and its meanings for modern period. The film's plot is a kind of story telling structure based on main character's memory. The short stories of main character represents that Jilov(main character's name)'s losing his own life. The audience can acknowledge that Jilov's life as a duck hunter who is cynical, ideological, lazy, and self-interest oriented person. This play provokes the audience to compare their life to Jilov's one because such comparison helps the audience recognize their lives as surplus style of life with nihilism. Jilov as a character represents one of Soviet's generation with the feeling of great loss in 1960s.

The proper estimation of physical and chemical properties of Earth materials and their structures at high pressure and high temperature conditions is key to the full understanding of diverse geological processes in Earth and planetary interiors. Multi-anvil press - high-pressure generating device - provides unique information of Earth materials under compression, mainly relevant to Earth's upper mantle. The quantitative estimation of the relationship between the oil load within press and the actual pressure conditions within the sample needs to be established to infer the planetary processes. Such pressure-load calibration has often been based on the phase transitions of crystalline earth materials with known pressure conditions; however, unlike at high temperature conditions, phase transitions at low (or room) temperatures can be sluggish, making the calibration at such conditions challenging. In this study, we explored the changes in Al coordination environments of permanently densified pyrope glasses upon the cold compression using the high-resolution ²⁷Al MAS and 3QMAS NMR. The fractions of highly coordinated Al in the cold compressed pyrope glasses increase with increasing oil load and thus, the peak pressure condition. Based on known relationship between the peak pressure and the Al coordination environment in the compressed pyrope glasses at room temperature, we established a room temperature pressure-load calibration of the 14/8 HT assembly in 1,100-ton multi-anvil press. The current results highlight the first pressure-load calibration of any high pressure device using high-resolution NMR. Irreversible structural densification upon cold compression observed for the pyrope glasses provides insights into the deformation and densification mechanisms of amorphous earth materials at low temperature and high pressure conditions within the subducting slabs.

The bioequivalence study of two tiropramide products was evaluated in 16 health male volunteers following intra-muscular injection. Test product was Tiram$^{(R)}$ injection (S Pharm. Co, Ltd.) and reference product was Tiropa$^{(R)}$ injection(D Pharm. Co., Ltd.). The drug concentration in plasma was determined by GC/MS for over a period of 8 hours after injection. Analysis of variance reveal that there are no differences in AUC (area under the plasma concentration-time curve from time zero to infinity), Cmax (maximum plasma concentration) and Tmax (time to reach Cmax). The differences of mean AUC, Cmax and Tmax between two products were 0.73, -1.385 and -12.994%, respectively. Minimum detectable differences (%) at ${\alpha}=0.05$ were all less than 20% given as a guideline (10.05, 17.90 and 19.01% for AUC, Cmax and Tmax, respectively). From these results, the two formulations of tiropramide are bioequivalent and thus, may be prescribed interchangeably.
