Leptin is a small polypeptide hormone secreted primarily by adipocytes. Leptin regulates energy balance by decreasing food intake and increasing energy expenditure. This study investigated the relationships between serum leptin levels and BMI (body mass index) in 49 adults in Pohang, Korea. The subjects were 25 males and 24 females, aged 21 to 64 years attending an outpatient clinic at Handong University Sunlin Presbyterian Hospital. Values are given +/- the standard error of the mean. Our study shows that the serum leptin levels in these subjects were positively correlated with BMI. The leptin levels were higher in females (2.39+/-1.82 ng/mL) than in males (0.43+/-0.455ng/mL), although lower than previously reported. We therefore compared the serum leptin levels from the male Korean subjects (BMI 24.3+/-0.74㎏/㎡) with serum from six British males with a similar BMI (23.4+/-1.48㎏/㎡). The serum leptin concentrations (1.76+/-0.76 ng/mL) were lower than that of plasma (4.28+/-1.66 ng/mL) in the British subjects. The serum leptin in the British subjects (1.76+/-0.76ng/mL) was higher than that in the Koreans. There was no correlation between leptin levels and BMI in either male (slope 0.018 ± 0.036, p=0.624) or female (slope 0.382±0.433, p=0.417) type 2 diabetic patients in Pohang, Korea. Taken together, our study shows that the serum leptin level in Koreans varies with the BMI, but is lower than that of BMI-matched British subjects.

This study investigated the purchase intention of green fashion products based on Rogers' Diffusion of Innovation theory and compared the differences between Korean and British consumers. In order to identify the impact of personal characteristics, this study also examined the effects of fashion innovativeness and LOHAS tendency on perceived attributes of innovation and intention to purchase. With a convenience sampling method, a survey questionnaire was distributed at popular fashion streets in each country. A total of 426 data were obtained, 203 from the UK and 223 from Korea. About 52% were females, and 69% were in their twenties. A factor analysis generated two LOHAS factors (health concerns and eco concerns) and four attributes of green fashion products (image improvement, symbolic superiority, observability, and compatibility). Two types of green fashion products (organic cotton t-shirts and organic cotton t-shirts with an environmental message) were provided to measure the purchase intention, respectively. The findings were as follows. British consumers were more likely to show LOHAS tendency and to perceive positive advantages of green products compared to Koreans; in addition, British consumers presented higher mean scores on the purchase intentions of organic cotton products. Fashion innovativeness was significant to predict image improvement and symbolic superiority, while eco concerns were significant in compatibility for both nations. Compatibility was important for both countries in order to explain the intention to adopt two types of organic products. In addition, image improvement was another predictor for purchase intention of organic t-shirts with an environmental message. Managerial implications were provided.

Mitochondria play a vital role in iron uptake and metabolism in pathogenic fungi, and also influence virulence and drug tolerance. However, the regulation of iron transport within the mitochondria of Cryptococcus neoformans, a causative agent of fungal meningoencephalitis in immunocompromised individuals, remains largely uncharacterized. In this study, we identified and functionally characterized Mrs3/4, a homolog of the Saccharomyces cerevisiae mitochondrial iron transporter, in C. neoformans var. grubii. A strain expressing an Mrs3/4-GFP fusion protein was generated, and the mitochondrial localization of the fusion protein was confirmed. Moreover, a mutant lacking the MRS3/4 gene was constructed; this mutant displayed significantly reduced mitochondrial iron and cellular heme accumulation. In addition, impaired mitochondrial iron-sulfur cluster metabolism and altered expression of genes required for iron uptake at the plasma membrane were observed in the mrs3/4 mutant, suggesting that Mrs3/4 is involved in iron import and metabolism in the mitochondria of C. neoformans. Using a murine model of cryptococcosis, we demonstrated that an mrs3/4 mutant is defective in survival and virulence. Taken together, our study suggests that Mrs3/4 is responsible for iron import in mitochondria and reveals a link between mitochondrial iron metabolism and the virulence of C. neoformans.

이 글은 인도의 대표적인 식민도시인 뉴델리, 마드라스, 캘커타, 봄베이(현재의 첸나이, 콜카타, 뭄바이)가 교과서에 어떻게 서술되고 있는지 살펴보고 이를 바탕으로 인도인의 관점에서 본 식민도시에 관해 분석하고자 한다. 인도 교과서에서 식민도시들은 도시가 만들어지는 과정과 그에 따른 정치 사회 경제 문화적 변화, 영국인과 인도인 간의 분리, 도시 계획, 식민지배 기간 동안 축조된 건축물들에 대해 서술하고 있으며, 이에 관한 서술관점은 '박탈, 배척, 차별, 저항, 도전'과 '기회의 부여, 수용, 흡수'의 관점이 혼재되어 있다는 점이 특징이다. 즉 식민도시를 둘러싼 서술관점은 대립적이면서도 상호 불가분의 관계를 견지하고 있는데, 영국의 통치 이데올로기가 반영된 식민도시가 가질 수밖에 없는 태생적 특징, 그 안에서 지배자와 피지배자가 만들어가는 사회, 문화적 특징을 단순화시키지 않고 다층적 고찰이 가능하도록 하고 있다. 그러면서도 피지배자로 겪었던 불합리한 차별과 배제에 대한 저항이 있었던 점은 분명히 하고 있다.

Cryptic species complexes are increasingly recognized in phycological research, obscuring taxonomy and raising questions about factors influencing speciation. A recent exploration of kelp genetic diversity on Haida Gwaii, British Columbia revealed the existence of a new species, Saccharina druehlii, which is cryptic with Saccharina sessilis. This suggests that molecular investigations further north may be required to elucidate the taxonomy and evolutionary history of this lineage. Although, for several decades, S. sessilis was considered a single highly variable species, its taxonomy has been far from straightforward. In particular, Hedophyllum subsessile (Areschoug) Setchell is now recognized as a synonym of S. sessilis in North America, but as a growth form of Saccharina bongardiana in Far East Russia. To resolve this taxonomic confusion, we sequenced mitochondrial (CO1-5P) and nuclear (internal transcribed spacer) markers of S. sessilis populations from the Aleutian Islands, Alaska, USA. Interestingly, none of our sequences matched S. sessilis sensu stricto. Instead, CO1-5P sequences from populations in the central and eastern Aleutians matched exactly S. druehlii with increasing sequence divergence occurring westward. Samples from Attu, the western-most island, composed a genetic group that clearly represents Kjellman's concept of Hafgygia bongardiana f. subsessilis and is distinct enough from S. druehlii and S. sessilis to potentially constitute a distinct species. Therefore, Saccharina subsessilis comb. nov. is proposed for this entity. Our results suggest the existence of a species complex at the crown node of S. sessilis and thus further investigation of Saccharina in Alaskan waters should be conducted to reconstruct the evolutionary history of this fascinating lineage.

An American ginseng(Panax quillquefolium L) industry has emerged in British Columbia, Canada over the past ten years. Interest has grown very rapidly and with this development, attention is now moving away from field production issues and emphasis is being directed to enhancements in ginseng storage, drying and processing. There is a dearth of knowledge on these aspects even though they are crucial to international competitiveness. Enhancement dicatates the application of a systems approach to optimizing the harvest and post - harvest production system(crop digging, pre - washing cold storage. washing, drying and post - drying storage). Research in British Columbia to date has focussed on drying and storage issues and has resulted in the design of an enhanced commercial drying system. The role of dryer management, loading rates, airflow rates and pre - drying cold storage on American ginseng root drying rates and root quality were examined. From the dryer management experiments, there are distinct advantages to size sorting root to yield optimum drying rates. If unsorted root is used, efficiency is increased if the trays are systematically rotated. Loading rate experiments illustrate that increasing rates above those currently used in commercial dryers are possible without any sacrifice in quality. This has significant implications for commercial drying. Pre - drying cold storage is a most significant tool for managing drying operations. Over a period of six weeks, no discernable decrease in quality was found as a consequence of cold storage. Further, the moisture loss and the associated root surface changes(loss of surface soil in storage for example) provide new challenges for root quality management. Continued research and technological innovation will be crucial in addressing the demanding challenges of the future.

This study has been done to review the historical development of the cataloging system of books with emphasis on those in England and the U. S. The findings can be summarized as follows: (1) In 1844, Sir Panizzi invented what seems to be the first of its kind in history to list the inventory systematically at the British Museum. It is believed to be a complete system consisting of 91 articles. (2) A comparatively systematic system was developed in America by Jewett. in 1852. Composed of only 39 articles, the system is considered a renovative one worked out with due regard to the infrastructure of a library. (3) In 1876, a classic system based on a lexicographical order was set up by Cutter. Rated as the best one that was designed by an individual, the theory has since exercised widespreading effects on cataloging. (4) American and British library scientists collaborated in printing several editions of numerous volumes on the principles of classification, but they are not believed fully successful in establishing a consistent and compressive system. Their efforts found significance rather in their being the first international collaboration and setting a foundation upon which the international system of today has been developed. (5) The ALA Rule, published concurrently in ALA and LC in 1949, had two parts in its classification, the list of authors and that of titles. Its scientific classification has completed the cataloging of books in its developmental stage. (6) The 1967 American-British Rules integrated the cataloging systems published under separate covers by authors and titles. The system as well as the 1961 Paris System has greatly contributed to the standardization of bibliographical description throughout the English-speaking countries. The International Standard Book Description standardized Bibliographic system has enabled the librarians in different countries to exchange their bibliographical sources easily, helped to overcome the language barrier in listing and contributed to the efficient reading of bibliographical records through machines. (7) The second edition of the Angelo-American cataloging Rules, promulgated in 1978 under the influence of the international standard bibliographical description, was the one in which all the previous Rules were revised to have their strong points. The adoption of punctuation system to employ the computerized data processing and the standardization of description are expected to improve the cataloging system not only in the English speaking countries but in the Universal Bibliographic Control as well.

본 연구는 신용장거래에서 은행의 독립지급의무 및 이 의무에 대한 예외적인 취급원칙과 방향에 대한 문제를 소재로 취급하였다. 독립원칙과 독립원칙에 대한 예외문제는 신용장의 본질에 관계되지만 국가마다 이러한 문제를 취급하는 태도에 차이가 존재한다. 본 연구에서는 영국에서의 태도를 분석하기 위해 독립원칙과 예외문제를 취급한 판례 중에서 지도적인 판례로 인정되는 사례를 중심으로 하여 독립원칙과 예외문제를 취급하는 영국의 입장을 분석하였다. 영국법원은 가능한 한 상인들 간에 형성되어 온 상관습을 존중하려는 입장을 취해 왔으며 독립원칙의 실무적인 적용에 있어서도 이러한 입장을 반영하여 독립원칙의 중요성을 강조하면서도 실질적으로는 개개의 사안마다 당사자의 형평을 고려하여 예외문제를 취급하여 왔다. 그러나 미국의 Sztejn 사건을 계기로 하여 영국에서도 독립원칙의 적용에 대한 태도의 변화를 보여 신용장거래에서의 사기뿐만이 아니라 기초계약에서의 사기도 독립지급의무에 대한 예외사유로서 인정하기 시작하였다. 그렇지만 독립원칙에 대한 예외의 운영방식에 따라 신용장제도의 존재의의가 상실될 우려가 있고 또한 발행의뢰인에 의해서 예외적용을 남용할 가능성도 있다는 문제점들을 감안하여 영국은 비록 사기적인 요소가 존재하지만 수익자 자신이 선의의 입장에 있는 경우에는 수익자를 보호하는 입장을 채택함으로써 예외인정과 예외의 남용문제 간의 조정을 도모하고 있다.

Purpose: Prior to cone-beam computed tomography (CBCT), orthodontic competence included radiological interpretation. Nevertheless, maxillary impacted canines (MICs), because of their position and adjacent complex anatomy, have been challenging to interpret, particularly with regard to root resorption. Although CBCT cross-sectional reconstructions of MICs yielded clearer insights into its diagnosis and treatment planning, the value of simultaneously using 2 different cross-sectional or multiplanar reconstructions of the CBCT datasets - orthogonal and curved/panoramic multiplanar reconstructions - has hitherto not been considered. Materials and Methods: Both orthogonal and curved/panoramic multiplanar reconstruction series of 5 screenshots were each reconstructed from the 5 cm×5 cm CBCT datasets of 15 separate MICs. Fifteen credentialled and experienced orthodontist volunteers reviewed 2 separate PowerPoints of 15 randomized series each, 1 week apart. Their review considered 6 factors that could affect treatment: the position and level of the MIC, the presence or absence of root resorption, ankylosis, cysts, and dilaceration. Results: All 15 orthodontists were statistically similar regarding overall years of experience and of CBCT use. Although either reconstruction alone allowed the orthodontists to determine whether ankylosis and, to a lesser extent, most of the other features were present or absent in the MIC, reviewing both reconstructions together was necessary to determine whether root resorption was present or absent in the adjacent tooth. Conclusion: Reviewing both orthogonal and curved/panoramic multiplanar reconstructions was necessary to evaluate the presence or absence of root resorption in the teeth adjacent to MICs and that of many other features.

The purpose of this paper is to investigate the distribution of /ju/ in British English, especially after the coronal sonorants /n, l, /r/. The sequence /ju/ is related with vowels such as /u/, /ʊ/, and /ʊ/, and has occasioned a variety of conflicting analyses or suggestions. One of those is in which context /j/ is deleted if we suppose that the underlying form is /ju/. The context differs according to the dialect we deal with. In British English, it is known that /j/ is deleted always after /r/, and usually after /l/ when it occurs in an unstressed word-medial syllable. To check this well-known fact I searched OED Online (the 2nd Edition, 1989) for those words which contain /n, l, r/ + /ju, jʊ, u, ʊ, (j)u, (j)ʊ/ in their pronunciations, using the search engine provided by OED Online. After removing some unnecessary words, I classified the collected words into several groups according to the preceding sonorant consonants, the positions, and the presence (or absence) of the stress, of the syllable where /ju/ occurs. The results are as follows: 1) the deletion of /j/ depends on the sonorant consonant which /ju/ follows, the position where it occurs, and the presence of the stress which /ju/ bears; 2) though the influence of the sonorant consonants is strong, the position and stress also have non-trivial effect on the deletion of /j/, that is, the word-initial syllable and the stressed syllable prefer the deletion of /j/, and word-medial and unstressed syllable usually retain /j/; 3) the stress and position factors play their own roles even in the context where the effect of /n, l, r/ is dominant.
