High $T_{c}$ superconducting B $i_2$S $r_2$CaC $u_2$ $O_{8+d}$ (BSCCO2212) films were prepared by a metallorganic decomposition (MOD) method. The metal organic solution of BSCCO2212 was spin-coated on MgO (100) substrates at 3000 rpm for 1 min. To achieve a high critical current density, we controlled heat-treatment conditions and atmosphere. The films were annealed at temperature 75$0^{\circ}C$ ∼ 80$0^{\circ}C$ in $O_2$ or air. We obtained c-axis orientated BSCCO thin films on MgO substrates. The annealed sample at 77$0^{\circ}C$ with $O_2$ showed the critical temperature about 77 K and critical current denstity of 1.19 ${\times}$ 10$^{5}$ A/$\textrm{cm}^2$ about 13 K.

Since it was founded in Korea in 1784, Korean Catholic Church has grown rapidly even under persecution. And now, its various activities have considerable influence on Korean society. However, the Korean Catholic Church record management not much is being done in excess of general record management for administrative purposes. Therefore, this study attempted to construct records management system that could systematically manage records of the Korean Catholic Church with Diocese Archives as the central figure. In order to do this, first the special characteristics of the Catholic Church records were analyzed, and the actual status of records management of Catholic Church was investigated. Next, applied the theory of records management to the Catholic Church system.

This qualitative case study focuses on five small and medium-sized enterprises which have put family-friendly management into successful practice. Through in-depth unstructured interviews with five human resources managers and ten employees, we describe each firm's approach to work-life balance including working hour reductions, breaks, work flexibility, and parental leave to build an overall picture. We also discuss the four key factors of the CEO's role; democratic communication between all staff, the usefulness of family-friendly certification as a starting point; and governmental support for promoting work-life balance at small and medium-sized enterprises. Finally, we suggest three political implications of governmental support, namely CEO education, changing the criteria of family-friendly certification to redefine working hours and work flexibility, and incentives specifically for small to medium-sized enterprises.

This study investigated the relation between children's internal-external locus of control and social comtetency. The subjects of this study were 453 mothers and their children of third and sixth grades in the five elementary schools located in Seoul. The modified version of Nowicki and Strickland's CN-SIE(Locus of Control Scale for Children) was administered to asses the children's internal-external locus of control. To assess the children's social competency, questionaire developed by Lee Kyung Hee(1993) was used. The major findings of this study were as follows : 1) There was significant interaction between grade level and sex in children's locus of control. Significant difference was found in children's locus of control in terms of children's social status level. 2) Significant difference were found in children's social competency in terns of children's sex and social status level. 3) Children's social comtetency was positively related to the internal locus of control orientation. 4) The relation between children's internal-external locus of control and social competency for boys was greater than that for girls. The relation between children's locus of control and social competency was not influenced by children's grade level, but affected by children's social status level. Social status level was positively related to the relation of the two concerned variables.

This study attempted to explore business and workers'needs for flexible work arrangements focusing on the case of a customer center business. We conducted in-depth interview and focus group interviews with the CEO of the company as well as with workers employed at the company in order to identify their need for flexible work arrangements. The subject of this study is a customer service center business that offers a variety of flexible work arrangements. We found that there is a need for flexible work arrangements in terms of both businesses and workers. These results suggest that flexible work arrangements can be activated when they meet the needs of businesses and workers. Flexible work arrangements can be activated when they meet the businesses'goals in human resource management and workers'goals for achieving work-family balance.

This research was to investigate physicochemical properties and antioxidative activities of rapeseed meal for the development of functional cosmetic material. Seventeen kinds of amino acid at rapeseed meal were found and glutamic acid concentration was significantly the highest (28.4 mg/g), followed by glycine, proline, arginine, isoleucine, and aspartic acid. Among various vitamins, cloline content was the highest (459.1 mg/kg), followed by niacin, tocopherol, and pantothenic acid. Among various fatty acids of rapeseed meal, oleic acid was the highest (36.7%), followed by linoleic acid and linolenic acid. DPPH radical scavenging activities of methanol and acetone extract of rapeseed meal at 2.0 mg/mL were 80.4 and 78.9%, respectively. The methanol and acetone extracts of rapeseed meal were a stable at the range of pH 3-9 on DPPH radical scavenging activity. The maximum reducing powers of methanol and acetone extract of rapeseed meal at 4.0 mg/mL were 0.7 and 0.68 OD 700 nm, respectively. The maximum superoxide inhibition activities of hot water, acetone, and methanol extract of rapeseed meal were 70.2, 75.2, and 81.4%, respectively. These results showed that the methanol and acetone extract of rapeseed meal can be used as a new source of functional cosmetic material.

It has been posited that in English, native listeners use the Metrical Segmentation Strategy (MSS) for the segmentation of continuous speech. Strong syllables tend to be perceived as potential word onsets for English native speakers, which is due to the high proportion of strong syllables word-initially in the English vocabulary. This study investigates whether Koreans employ the same strategy when segmenting speech input in English. Word-spotting experiments were conducted using vowel-initial and consonant-initial bisyllabic targets embedded in nonsense trisyllables in Experiment 1 and 2, respectively. The effect of strong syllable was significant in the RT (reaction times) analysis but not in the error analysis. In both experiments, Korean listeners detected words more slowly when the word-initial syllable is strong (stressed) than when it is weak (unstressed). However, the error analysis showed that there was no effect of initial stress in Experiment 1 and in the item (F2) analysis in Experiment 2. Only the subject (F1) analysis in Experiment 2 showed that the participants made more errors when the word starts with a strong syllable. These findings suggest that Koran listeners do not use the Metrical Segmentation Strategy for segmenting English speech. They do not treat strong syllables as word beginnings, but rather have difficulties recognizing words when the word starts with a strong syllable. These results are discussed in terms of intonational properties of Korean prosodic phrases which are found to serve as lexical segmentation cues in the Korean language.
