The problem whether a given grammar G generates an LL language or not is investigated in respect of LL transformable grammars. The previous work involves a nondeterministic intricated parser construction for the characterization of LL transformable grammars. The method hence does not give the intuitive understanding of the essence of LL languages. This paper suggests a characterization of LL transformable grammars based on grammatical derivations instead of the complicated parser construction. The new characterization contributes to intuitive understanding of the essence of LL languages.

The subclasses of LR grammars, k-transformable grammars, PLR grammars, and extended PLR grammars are LL covering transformable grammar classes. On other hand, their LL covering transformations are based on different formalisms, and hence, the relationship of the transformations is not obvious. This paper gives a unified model of the LL covering transformations, in which each LL covering transformable grammar class generates its transformation as a specific instance.

Objective : In this thesis we researched ${\ll}$Huangdimingtangjing(黃帝明堂經)${\gg}$ Methods : We refered to ${\ll}$Mingtangkongxuezhenjiuzhiyao(明堂孔穴鍼灸治要)${\gg}$ in ${\ll}$Huangdijiayijing(黃帝甲乙經)${\gg}$ and ${\ll}$Huangdineijingmingtang(黃帝內徑明堂)${\gg}$ Results and Conclusions : ${\ll}$Huangdimingtangjing(黃帝明堂經)${\gg}$ was written between West-Han(西漢) dynasty and East-Han(東漢) dynasty which was a summarized book about acupuncture point before Han(漢) dynasty. 1. "MIngtang(明堂)" means originally the hall where the emperor carried out politics but became a pronoun of acupuncture point in the field of Oriental medicine. 2. ${\ll}$Huangdimingtangjing(黃帝明堂經)${\gg}$ contains Five-elements theory which is specific property of Han(漢) dynasty. A many same named acupuncture point gathered not until Wu(武) emperor. The acupuncture point named "Jimen(期門)" which is the name of a military officer in Wu(武) emperor and cannot be found in ${\ll}$Huangdineijing(黃帝內徑)${\gg}$, I contains "long(隆)" which is the name of Shang(傷) emperor. As such it was written between West Han(漢) dynasty and Esst Han(漢) dynasty. 3. ${\ll}$Huangdimingtangjing(黃帝明堂經)${\gg}$ can be assumed the original edition by ${\ll}$Migtangkongxuezhenjiuzhiyao(明堂孔穴鍼灸治要)${\gg}$ in ${\ll}$Huangdijiayijing(黃帝甲乙經)${\gg}$ and ${\ll}$Huangdineijingmingtang(黃帝內徑明堂)${\gg}$ 4. The scholarship value of ${\ll}$Huangdimingtangjing(黃帝明堂經)${\gg}$ is rich in acupuncture point which described in detail futher more made possible of wide treatment. And also it referred a subordination of five shu(兪) acupuncture point ${\ll}$Huangdineijing(黃帝內徑)${\gg}$.

For real-time systems, multiprocessor support is indispensable to handle the large number of requests. Existing real-time on-line scheduling algorithms such as Earliest Deadline First Algorithm (EDF) and Least Laxity Algorithm (LLA) may not be suitable for scheduling real-time tasks in multiprocessor systems. Although EDF has low context switching overhead, it suffers from "multiple processor anomalies." LLA has been shown as suboptimal, but has the potential for higher context switching overhead. Earliest Deadline Zero Laxity (EDZL) solved somewhat the problems of those algorithms, however is suboptimal for only two processors. Another algorithm EDA2 shows very good performance in overload phase, however, is not suboptimal for muitiprocessors. We propose two on-line scheduling algorithms, Earliest Deadline/Least Laxity (ED/LL) and ED2/LL. ED/LL is suboptimal for multiprocessors, and has low context switching overhead and low deadline miss rate in normal load phase. However, ED/LL is ineffective when the system is overloaded. To solve this problem, ED2/LL uses ED/LL or EDZL in normal load phase and uses EDA2 in overload phase. Experimental results show that ED2/LL achieves good performance in overload phase as wet] as in normal load phase.oad phase.

This study was conducted to assess the nutritional status of the elderly from low income areas and its relationship with the indices of immunity. Ninety nine(male : 28, female : 71) healthy, subjects aged over 65 years staying in homes in Seoul were assessed with regard to their dietary intake and biochemical measurements. Their mean daily energy intakes were 1256kcal and 109kcal for males and females respectively. Mean serum IgG were 2356mg/dl in men and 2161mg/dl for women, higher than the normal range. Mean serum $C_3$ were 120.9mg/dl and 130.6mg/dl for males and females respectively and mean $C_4$ were 30.6mg/dl and 31.9mg/dl. The mean $C_3$ and $C_4$ were within the normal range and the proportion of subjects whose $C_3$ and $C_4$ were at a higher level than the upper limit were 15.4$\%$ and 16.3$\%$ respectively. Complement $C_3$ showed significant correlation with serum albumin(p〈0.01), serum cholesterol(p〈0.00l, serum TG(p〈0.05), LDL-C(p$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$$\ll$q0.001), VLDL-C(p$\ll$0.05), serum copper(p$\ll$0.05) and serum Ca(p$\ll$0.01).

$\ll$Yongchu(靈樞)$\gg$ is completed as a result of gathering several treatises about oriental medicine in B.C. 3c ~ A.D. 1c, and esteemed as a bible of oriental medicine, especially very much quoted in acupuncture fields. But the name of $\ll$Yongchu(靈樞)$\gg$ wasn't in existence at that time. Until A.D. 3c, it had been named after $\ll$Guguen(九券)$\gg$, given it's number of volumes, and since then mainly named after $\ll$Chimgueng(針經)$\gg$, given a word of the first volume. After A.D. 6c, under the influence of Taoism(道家), it was titled $\ll$Yongchu(靈樞)$\gg$, $\ll$Guhe(九墟)$\gg$, $\ll$Gureong(九靈)$\gg$ etc. Yongchu(靈樞), guhe(九墟), gureong(九靈) are words which is connected with Taoism(道家). In 1155, Sung Sa(史崧) published $\ll$Yongchu(靈樞)$\gg$, whim became a textbook of oriental medicine, so other titles disappeared since then. $\ll$Yongchu(靈樞)$\gg$, $\ll$Guhe(九墟)$\gg$, $\ll$Gureong(九靈)$\gg$, $\ll$Guguen(九卷)$\gg$, $\ll$Chimgueng(針經)$\gg$ are not the same book, but the contents are almost similar, and some letters are different. Especially the textbook, pubished by Sasung(史崧), had been related to the $\ll$Chimgyeng(針經)$\gg$, delivered to North-Song(北宋) dynasty by Jong-Gag Haung(黃宗慤), an envoy of an ancient Korean state(918-1392). So I expect to progress the study of medical exchange about it in the future.

Jang Sang-Hoon(장상훈) concluded that Dongyeo(東輿) seemed to be made between 1859 and 1866 but it was ahead of Cheonggudo(靑邱圖) in terms of the content and format. Accordingly he insisted that Cheonggudo was compiled based on the original version of Dongyeo which was supposed to be drawn between 1790 and 1834. This paper reappraised critically the previous researches and got several findings. Firstly, the changes of place names-4 places names were selected for the Jang Sang-Hoon's research and 2 were added in this paper-are reflected in the Yeodobiji(輿圖備志) and Dongyeo compiled by Choi Seonghwan(최성환) and Kim Jeongho(金正浩) between 1853 and 1856. Secondly, the sectioning format of Dongye shows some transitional character from the book style such as Cheonggudo to the folding style that was shown in Dongyeodo(東輿圖) and Daedongyeojido(大東輿地圖). Thirdly, the expression of the mountains in Dongyeo shares the same style which is shown in Dongyeodo and Daedongyejido. Fourth, Dongyeo contains the same information about old military bases and the castle locations in small local town centers that appear in Dongyeodo and Daedongyeojido but not in Cheonggudo and similar kinds of maps. In conclusion, Dongyeo and the original version of it are likely to be drawn by Kim Jeongho between 1853 and 1856 after Cheonggudo was made.

Objective : The purpose of this study is to investigate tinnitus of Plain Questions $\ll$素問$\gg$ and Miraculous Pivot $\ll$靈樞$\gg$. Methods : We conducted a study on the original text paragraphs of Internal Classic $\ll$內經$\gg$ containing the tinnitus and analysis of Yang, Ma, Zhang, Wang etc. We drew a parallel between tinnitus from Internal Classic $\ll$內經$\gg$ and matching diagnoses from western medicine. Results : The results were as follows. 1. Tinnitus in Plain Questions $\ll$素問$\gg$Tong Pyeong Heo Sil Ron <通評虛實論> was similar to the symptoms of diabetes mellitus complication and schizophreniform disorder in western medicine. 2. Liver fire tinnitus in Plain Questions $\ll$素問$\gg$ Yuk Won Jeong Gi Dae Ron <六元正紀大論> was similar to the symptoms of psychological distress in western medicine. 3. Phlegm fire tinnitus in Plain Questions $\ll$素問$\gg$ Ji Jin Yo Dae Ron <至眞要大論> was similar to the symptoms of meniere's disease and malfunction of autonomic nervous system in western medicine. 4. Blood deficiency tinnitus in Miraculous Pivot $\ll$靈樞$\gg$ Sa Gi Jang Bu Byeong Hyeong <邪氣藏府病形> was similar to the symptoms of anemia in western medicine. 5. Tinnitus in Miraculous Pivot $\ll$靈樞$\gg$ Gyeong Geun <經筋> was similar to the myofacial pain syndrome of the sternocleidomastoid muscle and the masseter muscle in western medicine. 6. Gallbladder deficiency tinnitus in Miraculous Pivot $\ll$靈樞$\gg$ Gwol Hyeong <厥病> was similar to the symptoms of otitis media and labyrinthitis in western medicine. 7. Kidney deficiency tinnitus in Miraculous Pivot $\ll$靈樞$\gg$ Gyeol Gi <決氣> and Hai Ron <海論> was similar to the symptoms of degenerative auditory organ in western medicine. 8. Tinnitus in Internal Classic $\ll$內經$\gg$ showed close relations with the symptoms of the wind character. Conclusion : We analyzed the original text paragraphs of Internal Classic $\ll$內經$\gg$ and explanations about tinnitus. Further studies are needed to compare oriental medicine and western medicine diagnoses to develop better treatments for tinnitus.
