This article examines how consumers in online environments depend on brand in making purchase decisions by product types. Previous research explains that the characteristics of online environments decrease the dependence on brand due to inexpensive search costs and affluent information quantity. But it is likely that in online environment, the dependence on brand will be differentiated by product types. We found that in search product, the availability of information decreased consumer's uncertainty, which, in turn, increased the dependence of brand. However, in experience products, the weakness of multi-sensory increased consumer's uncertainty, which resulted in the increase of the dependence of brand.

본 연구는 초기 편마비 환자의 손목에서 표면근전도 분석을 통해 근수축 개시 및 종료의 특성들을 알아보고, 임상적인 치료방법의 기초를 제안하고자 실시하였다. 연구대상자는 원주기독병원에 뇌졸중으로 입원한 환자 중 발병 후 3개월 미만인 13명과 원주시에 거주하는 대조군 7명이었다. 근수축 개시 및 종료의 지연은 표면근전도를 이용하여 손목굽힘근과 손목펴짐근에서 손목관절의 굽힘과 폄동작 시 3초의 근전도 신호음에 따라 가장 빠르고 강하게 최대 등척성 수축과 이완을 하여 신호를 수집하였다. 그 결과 편마비 환자의 환측은 건측과 대조군에 비해 손목관절 굽힘과 폄동작에서 근수축 개시및 종료가 유의하게 지연되었으며, 개시보다 종료가 더 유의하게 지연되었다. 따라서 초기 뇌졸중 환자의 근약화는 근육의 개시 및 종료의 반응시간 지연에 영향을 준다고 볼 수 있다. 앞으로 운동조절과 연관되어 기능적인 회복을 유도할 수 있는 근수축의 민첩성 훈련과 근섬유 동원의 효율성을 증진시키기 위한 치료방법들이 연구되어야 할 것이다.

In this paper, we are designed and fabricated circular polarization microstrip patch antenna of 5［GH］z bandwidth for the wireless LAN and the ISM. We are proposed new structure that removed the section which intersected at a right angle and were composed to four separated slots. The antenna of proposed structure could solve parasitic elements from intersected in a right angle and weak coupling efficiency from asymmetry between feed line and a slot. The proposed cross slots antenna is easily impedance matching and increased impedance bandwidth. Also this is increased efficiency and a bandwidth of antenna and reduce back lobe of radiation pattern. We designed 2${\times}$2 array antenna of 5［GHz］ band. It took impedance bandwidth 280［MHz］(VSWR < 1.5) and gam 12.5［dBi］

This paper investigates an extension of the uninorm (based) logic UL, which is obtained by adding (t-weakening, $W_t$) (($\phi$ & $\psi$) ${\wedge}$ t) $\rightarrow$ $\phi$ to UL introduced by Metcalfe and Montagna in [8]. First, the t-weakening uninorm logic $UL_{Wt}$ (the UL with $W_t$) is introduced. The algebraic structures corresponding to $UL_{Wt}$ is then defined, and its algebraic completeness is established. Next standard completeness (i.e. completeness on the real unit interval [0, 1]) is established for this logic by using Jenei and Montagna-style approach for proving standard completeness in [3, 6].

A study on strength decrease due to water contents through infiltration has been conducted with 9 rocks of high frequency in Korea. It has been proved that a strength decrease through infiltration has high dependence on rock strengths ranges while the species of rock have no impact. It has been found that the weaker the rocks are, the more sensitive the strength decreases are, and that water content of 0.5% corresponds to strength decrease of almost 50%. Another finding is that most rocks have a failure when water content is about one quarter~one half of its saturation. It has been shown that the weakening of rock strength due to water content results from leaching and the weakening of bonding strength of cementation materials.

본(本) 연구(硏究)는 국내(國內) 증시개방(證市開放)이 원화환율(貨換率)에 미친 영향(影響)에 대하여 이론적(理論的)인 모형(模型) 제시(提示)와 함께 실증분석(實證分析)을 시도하였다. 시간변동계수모형(時間變動係數模型)을 이용한 환율방정식(換率方程式) 추정결과에 의하면 1980년대 말 이후부터 증시(證市)를 통한 해외자금 유출입에 직접적인 영향을 주는 국내외(國內外) 주식수익율(株式收益率) 격차(隔差)의 환율절상효과(換率切上效果)가 지속적으로 증가(增加)한 것으로 나타났다. 반면 80년대에 걸쳐 주된 환율결정요인이었던 경상수지(經常收支)는 90년대 들어 환율변동에 미친 영향력이 현저하게 약화(弱化)된 것으로 나타났다. 이는 외환(外換)및 자본규제정책(資本規制政策)의 변화 등 구조변화(構造變化)에 기인된 현상으로 판단되며, 90년대에 들어서면서 환율(換率)이 경상수지보다는 경상수지와 자본수지를 더한 종합수지(綜合收支)에 더 큰 영향(影響)을 받고 있음을 의미한다. 위의 분석결과는 증시의 추가개방 등 자본자유화가 확대될 경우 원화절상압력(貨切上壓力)이 가중되고 이에 따른 수출경쟁력(輸出鏡爭力) 약화(弱化)로 종합수지(綜合收支)는 흑자(黑字)를 기록하면서 경상수지(經常收支) 적자(赤字)가 크게 늘어날 가능성이 있음을 시사한다. 따라서 수출경쟁력(輸出競爭力)을 유지하기 위해서는 실질실효환율(實質實效換率)기준으로 원화환율이 안정될 수 있도록 안정적(安定的)인 재정(財政) 통화운용(通貨運用)으로 대응해야 할 것이다.

This study explores the characteristics and discourse of creative work in advertising and investigates women's work experience and their problem. This will reconfirm the characteristics of advertising as creative labour. For this, it conducts in-depth interviews and analyzes them through a theoretical detour and a thick description. The study found the dominant discourse that creativity is their duty and ultimate goal. This dominant discourse makes the gendering of creative roles and representation languished. In spite of this, female creators with parenting have difficulty in reducing work ability, because conflicting identities weaken their self-regulation. This means that advertising is 'self-regulationized' labour.

For a long period, vowel reduction has been accepted as one of the most common pronunciation rules in Russian phonology. However, since the rules have been modified in many ways after the influx of loanwords, [a, e, i, o, u, ${\star}$]-including [e, o]-can now be pronounced in unstressed position, obeying the rule of vowel reduction. Especially in Modern Russian, along with the destruction of the consonant pronunciation norm due to some relatively complex changes it underwent palatalization, consonant pronunciation has been simplified, and as a response to such a phenomenon, the specialization of vowel pronunciation rule is now occurring. In other words, in the interrelation between consonants and vowels, as the pronunciation rules for consonants are simplified and thus the contrast between consonants is weakened, the degree of dependence on pronunciation of segment in the vowel pronunciation rule has been elevated. Therefore, the analysis says that the degree of vowel reduction depends on a vowel's distance from a stressed syllable is not enough; the influence of surrounding phonemes-including consonants-or the formative characteristics of words themselves should also be considered. The introduction of Max-noncorner/UnderLex, a/an Licence constraint that is related to non-declension nouns, and that of IdentC[back] and ShareCV[back], which are faithfulness constraint and share constraint respectively that are related to the nature of consonants stresses that vowel pronunciation rules should not be simply viewed as rules for vowels; The rules should be analyzed with emphasis on their correlation with surrounding phonemes.

The purpose of this paper is to review China's perception on the U.S. power after the global financial crisis. Although economic power of U.S. was declined by the global financial crisis, U.S. hegemony in the international order still maintains. Gap of national power between U.S. and China may be narrow because of decline of U.S. economic power. It can be predicted China will push a policy that secures an initiative of reform in the global monetary system and is going to take a more cooperative policy without U.S. hegemony power harming China's core interests.

This paper seeks to explore the effects of search strategies on innovation performance in the context of small and medium enterprises. The empirical results of 3,398 Korean SMEs demonstrate that there is a substitutive relationship between search depth and search width, and this substitutive relationship is weakened when a firm possesses collaboration experience. Furthermore, although these two types of search enhance innovation performance, the impact of search depth is greater than that of search width. The positive effect of search width on innovation performance is weakened when the firm adopts formal information protection mechanisms.
