This study aims to identify the effect of home physical therapy on patients who left the hospital after total knee arthroplasty, compared to the Daily living group, when it was applied to them, under the guidance of physical therapists. As research subjects, 20 patients that were scheduled to leave the hospital after unilateral total knee arthroplasty, were chosen, and they were randomly divided into a home physical therapy group(10 patients) and an Daily living group(10 patients) in order to conduct an experiment. During the 4-week research, home physical therapy was offered for 40 mins once for 5 days a week, and muscular strength, gait components were measured. For muscular strength, quadriceps muscle strength, hamstring muscle strength were measured, and as gait components, endurance, speed, step time, single-limb support were analysed. For this experiment, pre- and post-measurement were performed, and collected data were analyzed using SPSS ver. 18.0 statistical program. From the analysis of data, the following study results were obtained. Home physical therapy group and Daily living group both showed significant improvements in quadriceps muscle strength, hamstring muscle strength, and quadriceps muscle strength, hamstring muscle strength of home physical therapy group more significantly improved than Daily living group's. In relation to gait components, gait endurance, gait speed, step time significantly improved in both of home physical therapy group and Daily living group, whereas home physical therapy group only showed significant improvements in single-limp support. According to the comparison between two groups, gait speed, single-limp support and step time improved more significantly in the home physical therapy group than in the Daily living group. In conclusion, positive results were revealed in both home physical therapy group and Daily living group, with regard to muscular recovery of lower limbs of patients discharged from the hospital after total knee arthroplasty and walking, but considering the comparison results between two groups, it seems that applying home physical therapy is more effective than maintaining a daily life.

Yong-Suk. 1999. Syntax of Wh-Interrogatives: A Minimalist Perspective. Studies in Modern Grammar16, 39-88. This paper argues for two kinds of minimalist proposals concerning the constructions of wh-interrogatives: (i) the computational system of human language (C_(HL)) guarantees the same LF forms for wh-interrogatives of natural languages in accordance with the minimalist principle of poverty of interface interpretation, and (ii) the mechanism of unselective binding must be embodied as an LF principle for the scope-interpretation of wh-in-situ`s in multiple wh-interrogatives. The argumentation here proves that, for wh-interrogatives in English and Korean, the minimalist version of Kim`s (1988, 1990) LF uniformity hypothesis, proposed in this paper, must be adopted against such competing analyses as are suggested by Chomsky (1981, 1980, 1995), Huang (1982), Pesetsky (1982, 1984, 1987), Lasnik & Saito (1984), May (1985), Aoun (1985, 1986), Nishigauchi (1986), Choe (1987) and Watanabe (1992, 1993) among others, implying, from the perspective of minimalist assumptions, that the Q-.feature in C is virtually [-interpretable] at LF in all natural languages.

Yong-Suk Kim. 1998. Some A´-Dependencies in Korean. Studies in Modern Grammatical Theories 12, 53-82. This paper concerns some A´-dependency constructions involving null operator movement in Korean. This paper argues that the analysis of null operator movement accompanied with the strong binding condition should be adopted for topicalization of Korean, and then illustrates that this kind of analysis can be extended to some other conshructions such as relativization and null object constructions in Korean but not scrambling. In addition, I will make an attempt to explore how these constructions and the computation of null operator movement can be adapted to the recent framework of Chomsky`s (1993, 1994, 1995, 1996) minimalist program.
