  • 80% Ni-Permalloy is soft magnetic material with high initial permeability and low magnetic coercive force Hc, and is used to computer memory cores and minirelays of communication e-ngineering. In this paper 80 Permalloy thin film on copper cathode was alloy-deposited from Watts so-lution contatining FeSO4$.$7H2O. The amount of FeSO4$.$7H2O in the solution, pH, temperature of the solution and plating current density were varied as parameters and the resulting comp-osition changes of deposited film were analyzed electrochemically with respect to the parame-ters. From the above procedure electroplating conditions for deposition of 80 Permalloy were est-ablished as following: 17-21 g/$\ell$ of FeSO4$.$7H2O in Watts solution, current density 1.0-2.0 Amp/dm2, pH 2.5-3.0 and temperature range of 50-60$^{\circ}C$.

  • Since 2006, heated debates have taken place on both sides of the Pacific over the historical accuracy of Yoko Kawashima Watkins's So Far from the Bamboo Grove, the "historical novel" that depicts the author's painful escape from the just-liberated Korean peninsula to Japan. This study re-visits the controversies that fired up not only the whole Korean society but also not a few Americans and the American press. However, unlike most previous Korean studies on this novel, this study mostly focuses on both the responses of Korean feminists and those of Americans and the American press to the issue. This paper argues that the Korean feminists, who criticized their male compatriots for their feverish reaction, have the same problem as their compatriots, that is, the problem of seeing through a binary perspective that drowns or blurs individual differences. A similar framework is found operating in the Boston Globe's articles on the same issue. This study proceeds to discuss the pitfalls of liberalism underlying the American parents' and the American civil organizations' defence of Watkins and analyzes their poor historical awareness. The conclusion of this study is that So Far from the Bamboo Grove, dictated by an ideological prolepsis, erroneously inscribes the Cold War in the geographical space of the pre-Cold-War Korean peninsula and, as a result, symptomatically participates in the United States' anti-Communist world view.

A study on the analysis of Taegeuk Acupuncture focused on "Young Chu.GuChimSibYiWon" ("영추(靈樞).구침십이원편(九鍼十二原篇)"을 중심으로 한 태극침법(太極鍼法) 분석)

  • Objective : This study was conducted to underpin the theory of Taegeuk Acupuncture systematically and increase the utility of clinical trial and a range of application. Method : This study analysed ByungHaeng Lee's theory, who is the originator of Taegeuk Acupuncture, by focusing on "Young Chu GuChimSibYiWon" Result & Conclusion : 1. ByungHaeng Lee's thought about Viscera and Bowels is following medicine of Internal Classic. Even though JeMa Lee's thought about Viscera and Bowels has same name with ByungHaeng Lee's, but the functional meaning and related part is totally different. So, four constitution types in Taegeuk Acupuncture are different from four constitution types in Four-Constitution Medicine. Therefore, Taegeuk Acupuncture isn't related with Four-Constitution Medicine 2. On the authority of "Young Chu GuChimSibYiWon", we can extend 4 therapeutic acupuncture point combinations of Taegeuk Acupuncture to ten therapeutic acupuncture point combinations which tentatively named 'Five Viscera Source Point Acupuncture'. 3. To consider an example of eight constitutional acupuncture, Taegeuk Acupuncture thoroughly says constitutional acupuncture. Especially, JaeGyuKim's Taegeuk Acupuncture has specific diagnosis standard that after treating a patient with acupuncture, he checks an oppressive pain at the precordial region and a voiced sound at liver and then he makes sure constitution of patient. So we can consider JaeGyuKim's Taegeuk Acupuncture as constitutional acupuncture. However, it has to change the name of four constitution types to taegeuk greater yang person, taegeuk lesser yang person, taegeuk greater yin person, taegeuk lesser yin person so as to avoid confusion. 4. Taegeuk Acupuncture is markedly simple in comparison with other acupuncture, so it needs to extend the utility of clinics by enlarging treatment acupuncture points.

  • In this paper, we present a new hardware architecture for testing various cores embedded in SoC. The conventional solutions need much testing time since only one core is tested at single test period. To enhance this, S-TAM, a novel test architecture, and its controller which enable parallel testing of various cores are proposed. S-TAM supports bus sharing to broadcast testing and cores to be tested are selected by using it. In addition, S-TAM controller enables the effective SoC test by simultaneous controlling the various test cores which are based on the different test architectures like IEEE 1149.1 and IEEE 1500.

  • In order to establish the national standards of neutron measurements, a manganese sulphate ($MnSO_4$) bath system was developed under the IAEA technical support. This bath system was made up of a spherical s.s. 316 L bath, of 3.5 mm thick and of 125 cm internal diagmeter, filled with a manganese sulphate solution, a solution circulating system, and a $^5Mn\;{\gamma}-ray$ monitoring system. The solution pumped from the bath was introduced into a Marinelli beaker-type monitor vessel which was equipped with two seperate detectors, $3.8cm{\phi}{\times}3.8cm$ NaI(T1) crystals. The performance of the system were tested using the neutron sources, $^{241}Am-Be\;and\;^{252}Cf$, mounted at the center of the bath. From the decay curve analysis of $^{56}Mn$ activity, neutron emission rate of $^{252}Cf$ by the comparative method was obtained to be $3.71{\times}10^7\;n/s\;per\;50{mu}g$ as of November 15, 1985.

  • Present study was carried out to elucidate the effect of phorate (0,0-dietyl S-ethylthiomethyl phosphorodithioate), an organophosphorus insecticide on the acetylcholinesterase(AChE) and cholinesterase(ChE) activity in the chicken brain and plasma. The inhibitory effect of phorate and its metabolites on AChE and ChE activity was also increased in the order of phorate (p=S,S)$(p=S,SO_2)<phoratoxon$ (p=O,S)$(P=O,SO_2)$. Acute oral $LD_{50}$ of phorate was 1.02mg/kg. After oral administration of phorate, the activity of plasma ChE was inhibited more rapidly then that of brain AChE, whereas recovery of plasma ChE activity was more rapid than that of brain AChE activity.

  • The energy-absorbing characteristic of impact limiters affects the cask design so significantly that it should be evaluated as accurate as possible. The objective of this study is to find the influence of the impact limiter's steel case and gusset plates which enclose the shock absorbing cellular material on the impact energy absorption. The influence of impact limiter's steel case and gusset plate stiffeners on the impact energy absorption behavior under horizontal drop impact was evaluated for a radioactive isotope transport cask. Though the impact limiters mitigate the impact damage of the cask, the impact limiter's steel case and gusset plate stiffeners increase the impact force so significantly that should be designed as soft as possible. The impact analysis without considering impact limiter's steel case and gusset plates stiffener gives non-conservative results, so the stiffness of the steel case and gusset plates should be considered in impact analysis.

  • Excavated costumes at the women's tomb in 17C have been sustained good condition. These materials give us that Jang ui(長衣) and so chang ui(소창의) with chechori(유), skirt, trousers(袴) reflects on women's fashion style at that time. By seeing these costumes, we can get the characteristics of costumes in mid-chosun era with chechori, skirt, jang ui, so chang ui etc. The features of chechori in this area are follows : form - diagonal gil, collar - kalkit and tangkokit, length - about 50cm, materials - silk, cotton, grass-cloth, kind - single, double. clothing padded with cotton wool etc. It is the first time that chang ui, one of Po, is excavated in this area. There are three pieces of jang ui which is significant data to study deeply on the costume in 1700's. Jang ui mainly made of silk in pattern, silk, cotton and decorated stylish printing on the robes. With these material and style, we can induce the mode of mid-chosun period. Through comparative studying we have many chances to understand women's the garment for the dead(염습의) in mid-chosun period.

  • The purpose of this study is to investigate the aesthetic characteristics of check fashion of the 20th century and to analyze the formativeness for them shown in recent collections. The results of this study are as follows; 1) Before the First World War, check patterns were used for S silhouette dresses and hobble dresses. During the two wars, they were used for garçonne style dresses and military suits. Check patterns were used for mini style in the 1960s, uni-sex style in the 1970s, and power suits in the 1980s. Especially after the 1980s, check patterns have followed the fashion trend of each season and appeared in retro styles. Consequently, the aesthetic characteristics of check dresses of the 20th century are traditionality, ornamentation and eclecticism. 2) Traditionality of check fashion shown in recent collections was implied in the classic styles like suits with its grey glen check, avant-garde styles like boxy coat with its dark blue tartan check, and so forth. Ornamentation was shown in the modern styles like jackets decorated with block check colored white and black, casual styles like bomber jackets with hound tooth check colored white and black, and so forth. Eclecticism was reflected in the romantic styles like one-piece dresses with hound tooth check colored white and light blue, elegant styles like low-cut dress with its dark blue window pane check, ethnic styles like long cape with gingham check colored white and black, and so forth.
