        金賢聲 건국대학교 1967 學術誌 Vol.8 No.1

        From the view-points of the current condition of sericulture in our country, the followings are the summarized means by which the structural improvement of sericulture of our country can well be attained. 1.Making such efforts as to give each one farming household 40 acres of mulberry field whereby these farming households each can raise 16 boxes of silkworm seed annually to Produce 480 kg of cocoon. The efforts could well be a mean getting rid of the deep-seated obstacles of the poorness which stands in the way of the development of our sericulture and also promoting a proper adjustment of our farming management. 2.putting an end to the customary silkworm-raising which usually are being done one or two times during either spring or spring-autum and, by applying a method of prolific periods such as four times per a year for silkworm raising aiming at the adjustment of labor distribution and at the same time making the most of the available idle labor for the productive sericulture. Especially, during the busy farm seasons, difference in time method for fetching of silkworms could be applied in order to promote the adjustment and distribution of labor. 3.Correcting the existing farm-management from which hither-to has been centered on rice and barley, and promoting the rationalization of sericulture-farming organization by introducing an appropriate form of sericulture. Namely, by means of reclaimed mulberry field or converting the current rain-water rice fields into the mulberry ones or partly turning the current fields into the mulberry ones, aiming at over-all reorganization of the existing farming-sericulture so as to bring forth at minimum 40 acres of mulberry Held and to have at minimum annually 16 boxes of silkworm seed. 4.The scale of the sericulture management could well be summarized as the above, and during young larval period silkworm raising must be performed jointly through the box rearing and during the adult period it must be done cooperatively throughout a year with mulberry wattles with loaves.

        Brown-Séquard Syndrome Caused by Spinal Cord Infarction: A Case Report and Literature Review

        김현성,김석원,이승명,신호 대한척추신경외과학회 2010 대한척추신경외과학회지 Vol.7 No.4

        Brown-Séquard syndrome is usually observed in patients with compressive myelopathy due to trauma, cord tumors, and degenerative spinal diseases. Brown-Séquard syndrome resulting from spinal cord infarction is rare. We report the case of a 46-year-old man who presented abruptly with left hemiparesis and diminished pain and temperature sensations on his right side below the C6 dermatome. Cervical spine magnetic resonance imaging revealed abnormally high signal inten- sity in the left lateral parenchyma of the spinal cord at the level of C4 and C6 on T2 weighted images. After excluding other possible causes, a clinical diagnosis of Brown-Séquard syndrome of probable vascular onset was made, associated with spinal cord infarction. The patient was managed conservatively with intravenous fluids and corticosteroids. However, his condition remained mostly unchanged after six months. Here, we present a rare case of spinal cord infarction causing acute Brown-Séquard syndrome, with a review of the literature.

        Modified Authenticated Key Exchange Protocol for SIP using ECC

        김현성,이성운 보안공학연구지원센터 2010 보안공학연구논문지 Vol.7 No.4

        The authentication procedure in session initiation protocol (SIP), an IETF standard protocol for initiating an interactive user session, typically uses HTTP digest authentication, which is vulnerable to many known attacks. To cope with the problems, Wu et al. proposed a new authenticated key exchange (NAKE) protocol for SIP based on the Elliptic Curve Cryptosystem. However, this paper shows that the NAKE is insecure against the off-line password guessing attack and proposes a modified authenticated key exchange (MAKE) protocol for SIP. The MAKE fits neatly in the SIP protocols as described in RFC 3261.

        Robust Remote User Authentication Schemeusing Smart Cards

        김현성,이성운 보안공학연구지원센터 2010 보안공학연구논문지 Vol.7 No.5

        Two user authentication schemes were recently proposed using smart cards. They do not need to maintain a verification table in registration server, which is one of the good and necessary aspect in the password based schemes. In this paper, we show that they are not secure against some attacks. Then we propose a robust remote user authentication scheme to withstand the flaws in them but preserve the same merits of them. Our scheme could be efficiently used in wireless communication applications.

        日本ベンチャ-の企業成長と資金調達構造

        김현성 한국외국어대학교 일본연구소 2008 日本硏究 Vol.35 No.-

        The purpose of this paper is to examine which factors affect the financing of Japanese ventures, with focusing on firm growth. On methodology, the paper collects the financial data-set of sample firms' Nikkei NEEDS provides and conducts correlation and multiple regression analysis to reveal the relationship between their growth and financing. The result can be summarized as followings: at First, Japanese ventures finance from its owners or the companies they spin off rather than institutionalized roots like debt financing. the Second, the paper find out that the higher their age become, the ratio of the debt financing to the capital market financing has come to be increased. Finally, the debt financing through commercial banks or governmental institutions concerning SME financing is also preferred by Japanese ventures, as its determination and review on the financial state of corporate on whether lenders are going to finance or not in speedy rather than additional capital financing at market

        中小企業政策とその?換に?する韓?日比較

        김현성 한국외국어대학교 일본연구소 2007 日本硏究 Vol.32 No.-

        A Comparative Analysis on SME policy and its Switch in Korea and JapanThe purpose of this paper is to research with the comparative analysis on how small and medium-sized(:SME) policy has been changing in Korea and Japan. Furthermore, the paper examines on factors to affect the fluctuation of SME policy in both countries. On Methodology used, I adapt the convergency theory and analytic description not static analysis. The result can be summarized as followings : at First, somewhat SME policy in both countries has been developing with a convergent point not only in industrializing era but after catching-up industralization, in that they have been focusing on fostering venture businesses from the protectionism before 1990s'. the Second, the post-industrialization and lowing entrepreneurship have significantly operated as the background of the policy switch. the Third, some differences, however, exist in bringing up venture businesses. It seems a good example whether locality and autonomy on the new policy are considered significantly or not in particular.

        백서(白書)에 나타난 일본의 대(対)아시아 통상정책과 해외직접투자

        김현성 한국일어일문학회 2010 日語日文學硏究 Vol.73 No.2

        本稿は、日本の通商政策においてアジアというエリアがどのように位置づけられているか、そしてその位置づけがどのように変わってきたかを、関連する白書の内容検討を通して分析を行った。なお通商政策は自国企業の海外活動の展開を反映する側面があることに着目し、日本企業の海外直接投資の展開過程に現れる特徴を明らかにし、両者の相関関係についての分析を試みた。その結果は以下のようにまとめることができる。第一に、白書に現れたエリア認識をみると、2000年代初頭を境に日本の通商政策はアジアという空間を重視しはじめた。第二に、通商政策の対象としてのアジアの位置づけは、従来の生産機能だけを念頭においた国際分業での役割に重点が置かれたのに対し、市場としてのアジアとそのエリアにおける企業間の国際ネットワーク関係を重視しはじめた。第三に、これらの変化の根底にある要因を探ってみた結果、すでに1990年代半ばからアジア向け海外直接投資が市場志向型に転換しはじめたことが明らかになった。その根拠は、海外進出の日系企業の現地法人での輸出比率の低下と円ドル為替レートとの連関関係の低下という側面から探ることができる。すなわち日本の對アジア通商政策におけるアジアというエリアを市場としての役割により注目したことは、日本企業の海外直接投資の志向型の転換を反映したものだったといえるのである。

        전후 일본의 동아시아공동체 구상의 전개와 인식의 변용

        김현성 한국일본사상사학회 2009 일본사상 Vol.0 No.17

        2009年に鳩山政権が登場した以来、アジア諸国では日本の東アジア共同体への期待が高まりつつあるものの、東アジア共同体をめぐる日本での議論はそれほど新しい概念とは言えない。そこで、本稿は戦後日本で議論されてきた東アジア共同体構想の展開とともに国家間関係と交流メカニズムに対する認識がどのように変容してきているのかを考察した。その結果は次のようにまとめることができる。 第一に、国家関係においては、1990年代半ばごろまでの日本はアジア太平洋という地域コンセプトに基づき、競争の観点からアプローチした。それ以来、アジア太平洋からアジアへの回帰が東アジア共同体にアプローチする認識の基盤となってきた。学術レベルでの議論は、その方向性の変化に論理の基礎を提供した。その認識の転換を言い換えれば、日本の東アジア共同体構想は、19世紀後半の‘脫亞入歐’から‘脫歐入亞’へと再構築される過度期の中で変容してきたといえる。 第二に、共同体での交流メカニズムに対する認識は、1960年代と1970年代は国益に焦点を当てることによって経済分野に限定した共同体論が主流であった。しかし、国益からの切り放すことによって思想や社会・文化分野での交流拡大へとその論点が広げられてきた。共同体として連帯感という課題が先決の問題であるという認識の転換が反映したものである。 以上の2点は、戦後日本の東アジア共同体の展開過程においては、国家間関係からみた地域カテゴリは限定されつつあったのに対し、交流メカニズムはソフトな分野にまで拡大してきたとの特徴の現れであるといえる。
