When channel catfish was injected with Cd and Zn chloride, the liver of the Cd-treated channel catfish was transiently activated to synthesize metallothionein(MT) mRNA and MT-like proteins. The poly(A)^+ mRNA of about 400 bases long was detected in the Cd-treated channel catfish liver with synthetic DNA probes (27 mer), which were conserved sequences in rainbow trout MT cDNA and human MT cDNA, by northern blot hybridization experiment. Amount of the mRNA from Cd treated channel catfish liver was enough to detect translation products in vitro, using the rabbit reticulocytelysate cell-free translation system. These translation products were MT-like proteins, which were about 6.5 kD in size on SDS-PAGE.

The demand for electric vehicles powered by lithium-ion batteries is continuously increasing. Recovery of valuable metals from waste lithium-ion batteries will be necessary in the future. This research investigated the effect of reaction temperature on the lithium recovery ratio from hydrogen reduction followed by water leaching from lithium-ion battery NCM-based cathode materials. As the reaction temperature increased, the weight loss ratio observed after initiation increased rapidly owing to hydrogen reduction of NiO and CoO; at the same time, the H₂O amount generated increased. Above 602 ℃, the anode materials Ni and Co were reduced and existed in the metallic phases. As the hydrogen reduction temperature was increased, the Li recovery ratio also increased; at 704 ℃ and above, the Li recovery ratio reached a maximum of approximately 92%. Therefore, it is expected that Li can be selectively recovered by hydrogen reduction as a waste lithium-ion battery pretreatment, and the residue can be reprocessed to efficiently separate and recover valuable metals.

Objective:This study was performed to investigate the prescribing patterns of antimanic agents in the treatment of acute bipolar disorder inpatients in Korea from 1990 through 2000. The results will serve as the basic data for the practice guideline for the pharmacotherapy of bipolar disorder patients in Korea. Method:Retrospective chart review of bipolar disorder inpatients of Soonchunhyang Medical Center in Seoul and Chun-An was conducted for each of the year 1990, 1995, and 2000. The following data are collected ; 1) demographic data, 2) history of bipolar disorder, 3) length of hospital stay, 4) detailed drug titration records of antimanic agents and antipsychotic agents. Results:During the last decade, the frequency of lithium monotherapy was decreased obviously. Instead, more than half of the patients in 2000 were on combination therapy of lithium and anticonvulsants. Lithiumvalproate combination was the preferred strategy and the use rate of carbamazepine has been decreased. In addition, most of the patients were given antipsychotic agents during the last 10 years. And recently, atypical antipsychotics were increasingly prescribed. These changes in the field of pharmacology of bipolar disorder have resulted neither in shorter hospital stays nor lower dosages of concurrent neuroleptics. Conclusions:The results indicate the trends in the prescribing of antimanic agents for the treatment of bipolar disorder in Korea across the past 10 years. Mostly, the change seems to correspond to the international practice guideline. More systematic research is needed to find out the clinical benefits of the anticonvulsants in the real practice of treatment of bipolar disorder.

The physical environment is one of several service characteristics that are important contributors to service quality. As far as public service buildings, public community facilities serve as arenas for education, social interaction, leisure, and health activities for community districts. The purpose of this study was to investigate the physical state of public community facilities and use of public community facilities in Seoul and Suwon and to identify expectations of users toward the physical environment and service aspects. Site visits to four public community facilities were conducted and surveys were distributed for this study, with one hundred ninety two questionnaires analyzed. Results suggest that in order to provide more equal benefits and service to the public, cities should provide several smaller instead of one large complex community facility. Additionally, facility users indicated large gaps between their expectations and the current state of facilities due to lack of storage, noise and difficulty of use. In general, physical characteristics should be improved rather than employee's attitudes and service behaviors, resulting in greater service quality.

인물화(人物畵)의 사의성(寫意性)에 관한 연구(硏究)

이소영,Lee, So-Young 한국조형예술학회 2007 조형예술학연구 Vol.11 No.-

동양회화에서 '형사(形似)'와 '신사(神似)'는 대상을 표현하는데 중요한 화두로 인식되었으며 특히 인물화에서는 인물의 정신을 전달하는데 있어 '형사'와 '신사'는 더욱 중요하게 다루어져 왔다. 고개지(顧愷之, 약$345{\sim}406$)는 형사와 신사를 표현하는데 있어 '전신(傳神)'의 개념을 명확하게 제시함으로써 회화비평의 중요한 기준으로 삼았다. 그는 먼저 형(形)을 통해 정신을 드러낼 수 있음(이형사신(以形寫神))을 제시함으로써 창작자는 작품에 '의(意)'를 그려내고 감상자는 표현된 '의'를 체험하는 것을 중요한 예술행위로 인식하였다. 따라서 인물화는 형상의 재현이라기보다는 그려진 대상의 인격과 성품을 드러내는 것이며, 창작자 스스로 인격을 도야하여 성인의 도(道)를 표출하는 것을 예술이라 여김으로써 예술적 심미주체인 작가의 의를 중시하였는데 이른바 이것이 전신의 개념으로 발전되었다. 본고에서는 고개지의 '전신사조론(傳神寫照論)'이 소식(蘇軾)의 '사의론(寫意論)'으로 계승되고 이러한 사상이 한국에서는 이형사신(以形寫神)의 원리에 충실한 윤두서(尹斗緖)의 '화도론(畵道論)'으로 이어지는 사의론의 전개과정을 알아보고자 한다. 또한 인물화에 내재된 사의성에 대하며 논하고자 하는데 작품에서 형사와 신사의 구분이 모호하듯 '사의성(寫意性)'의 판단의 기준 또한 명확하게 정의하기는 쉽지 않으나, 역대 작품분석을 통하여 보면 작품제작 시 입의단계(立意段階)에서 작가와 대상과의 관계가 중요하며 본고에서는 그 요소를 네 가지로 제시하였다. 현대미술은 기법의 홍수라 여길 정도로 많은 기법들이 혼재하고 있으며 마치 상품 특허를 내듯 기법이 작가를 대신하는 현상이 벌어지고 있는 현실이다. 본 논문은 인물화에 내재된 '사의성을 파악함으로써 기법 보다는 작가의 구사인 의(意)가 중요함을 입증하여 무분별하게 유행에 편승하는 기법의 남용보다는 창작자의 철학적 기반과 정신적 수양이 중요함을 주장하고 사의론과 실제 인물화를 대입시켜 살펴봄으로서 동양회화의 특성인 사의성을 규명하여 살펴보는데 그 목적이 있다. The East has recognized 'similar forms' and 'similar spirits' as important topics in expressing an object. Figure painting, in particular, has attached importance to 'transmission of spirit'. Gu Kaizhi (345-406) definitely presented the transmission concept and made it the moot important criterion in painting criticism. By identifying the possibility of revealing spirit through a form, he recognized the 'expression of will' in a creator's work and the experience of such 'expressed will' by an appreciator to be the essential acts of art. Thus, he said, a figure painting revealed the character and nature of the depicted object rather than reproducing its form. Regarding art as a person creating the saintly way of life via developing own character, he attached importance to the will of an artist as the central aesthetic subject. This dissertation explores the keynote of the spirit expressing an artist's inner world and the external shape of a figure. It is carried out by investigating the process of Gu Kaizhi's theory (namely spirit transmission and revelation in painting) leading to Su Dongpo's assertion that "the nature of things" and later leading to Yun Duseo's "theory of the way of painting" as the spirit-transmission theory faithful to the principle of revealing spirit through a form in Chosun. The chronological study of the aforementioned works reveals that the relation between an artist and an object is important at the stage of setting aim in producing a work, and this dissertation analyzed it with four elements: (1) creating work based on the viewpoint of nature that heaven and man are one; (2) reflection of the creator's character (including his/her nature, temperament, spirituality, and emotion during the creation) and the artistic merit of a picture; (3) the dialectic unification between the true and the false through space which is a volitional state as creative thinking space; (4) importance of artist's will above the technique used such that a purposeless, inactive and plain work (where human will is combined with heavenly one) was pursued because the picture is regarded coming from the mind created in the unity of host/artist and guest/object. Thus, through his/her intuitive insight is the world where self is united with the cosmos symbolized. Such expression of an artist's inner world and the external shape of a thing pursues the stage of materialization and creates the new modes such as using space, a variety of brushstrokes, and accidentality and improvisation of India ink. In particular, the writer sees that such expression which enables a creator to express his/her nature or personality (and even the emotion) at the time of creation will be highly worth studying in the future, in accord with the pursuit of contemporary painting being expressed as an abstract aspect.

Objective To determine the correlation between the physical examination and the computed tomography of femoral anteversion and tibial internal torsion. Method The angle of internal and external rotation of hip for femoral anteversion and thigh-foot angle for tibial internal torsion were measured by a rehabilitation physician for 116 young children with toe in gait. Within a week after the physical examination, the angle of femoral anteversion and tibial internal torsion were measured by computed tomography for comparison. Results Two-hundred thirty-two lower limbs of 116 children (64 girls and 52 boys) included in this study whose mean age was 6.4±2.7 years for girls and 6.8±2.8 years for boys. The Pearson correlation coefficient between the angle of internal rotation of the hip and the femoral anteversion measured by computed tomography showed 0.62 in right side and 0.55 in left side, an indication of significant correlation (p<0.01). The Pearson correlation coefficient between the thigh-foot angle and the tibial internal torsion measured by computed tomography showed 0.50 in right side, 0.42 in left side, an indication of significant correlation (p<0.01). Conclusion Children with toe-in gauts showed a significant correlation between finding of physical exam (i.e. TFA and femoral internal torsion angle) and those of CT omages (i.e. tibial torsion angle and femoral torsion angle).
