[연구목적] 본 연구에서는 상대적으로 연구가 부족했던 BDI와 지역별 경제변수들(고용률, 실업률, 수출액, 수입액, 광공업생산지수, 컨테이너 물동량)간의 연관성을 실증분석 하여, 시사점을 제공하였다. [연구방법] 본 연구는 BDI와 지역별 경제변수 등에 대한 관련 논의, 기존에 수행되었던 연구들을 검토하였다. 본 연구에서는 부산과 인천지역을 대상으로 2012년 1월부터 2019년 9월까지의 기간 동안 BDI와 지역별 경제변수들 간의 관련성을 비교분석 하였다. 이를 위해, 상관관계분석과 그랜저인과관계분석 등을 이용하였다. [연구결과] BDI와 지역별 경제변수들 간의 관련성을 비교한 연구결과를 보면, 부산과 인천지역 모두 동일하게 나타났다. 상관관계분석결과, BDI와 실업률 및 수입액 간에는 음(-)의 관계, 다른 변수와는 양(+)의 관계를 보였다. 컨테이너 물동량은 실업률과는 음(-)의 관계를, 다른 변수와 양(+)의 관계를 보였다. 그랜저인과관계분석결과, BDI는 광공업생산지수와 컨테이너 물동량을 선행하고 고용률과 컨테이너 물동량은 서로 양방향으로 선행, 실업률과 수입액은 컨테이너 물동량에 대해 선행성을 가지는 것으로 나타났다. 다만, BDI는 부산에서는 지역경제변수들에 대해 선행성을 가지고 인천에서는 반대로 지역경제변수들이 BDI를 선행하는 것으로 나타났다. [연구의 시사점] 본 연구를 통해 확인한 이론적․실무적 시사점으로는, 부산지역 경제가 BDI에 의한 영향을 보다 많이 받기 때문에 지역 경제정책을 국제 해운업 상황에 따라 시의성 있게 실시해야 할 것으로 보인다. 또한, 컨테이너 물동량이 항만 지역경제에 미치는 영향이 상당하므로 이를 고려한 정책이 필요할 것으로 보인다. [Purpose] This study empirically analyzes the relationship between BDI and regional economic variables, such as employment rate, unemployment rate, exports, imports, industrial product index, and port container volumes, which were relatively lacking in research. [Methodology] This study reviews related studies on BDI and regional economic variables, and previous studies. In this study, we compared and analyzed the relationship between BDI and regional economic variables during the period from January 2012 to September 2019 in Busan and Incheon. For this purpose, correlation analysis, Granger causality analysis, and variance decomposition were used. [Findings] The results of the study comparing the relationship between BDI and regional economic variables are as follows. The same was true for both Busan and Incheon. As a result of the Granger Causality Analysis, BDI preceded the industrial product index and the port container volumes, and the employment rate and the port container volumes were bi-directional. However, BDI has precedence over regional economic variables in Busan and regional economic variables precede BDI in Incheon. [Implications] Therefore, this study provides theoretical and practical implications by empirically analyzing the relationship between BDI and regional economic variables, which have been relatively overlooked.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

This study is about women's veils from Chosun period housed in various museums and see how they reflect the escalating inequality between the two sexes based on Confucianism and its social ramifications including the strict rules that kept women from reely communicating or staying in same quarters with men from tender age. I first visited various museums to see what kind of veils they had in their collections and then looked at reproductions, museum catalogues, and other studies to get a better understanding of the designs, colors, and fabrics of the veils in each collection and came to following conclusions: 1. I looked at 26 veils of 7 different styles both in person and in museum catalogues, and they included 2 Neouls, 3 Myunsas, 12 Jahngots, 4 Chuneuis, 1 Sahkgat, 3 Junmos, and 1 Garima. Various documents attest to the existence of one more style of veil, I.e.skirt-shaped veil, but there was no specimen of the type. 2. Museums had various types of veils for women, but most of them dated from late Chosun period. 3. Female veils in Chosun period had clearly-defined characteristics depending on their wearers. Each type gad its own fabric, color, and form, so one could tell the status of the wearer just by looking at it. 4. The veils that I found at museums around the country had following characteristics:. Neoul was worn by high-class women and it covered up the face better than other types of veils. Myunsa was also called Myunsapo, and it featured brilliant gold foils to mark the exalted status of the wearer. Jahngot was originally a robe for both sexes, but it turned into a type of veil for low-class females in late Chosun period, and there were more Jangots in museum collections than any other type of veils. Chuneui has various styles and it has a cotton lining so low-class women wore it to both cover the face and to stay worm. Sahkgat was worn by low-class women for its convenience. Junmo was elaborately decorated and showy, and it was worn by courtesans. Garima was worn by courtesans or professional women in medicine, and unlike other type of veils, it showed the face of the wearer.

Objective : The aim of this study is to evaluate internal reliability and correlation among assessment instruments of knee OA. Methods : Data were obtained from 85 patients with knee OA. They were asked to answer VAS pain scale, two disease-specific questionnaires (WOMAC and LFI) and one instrument about health-related quality(KHAQ). Reliability was assessed using cronbach's alpha. Correlation was assessed by examining the pearson's correlation coefficients. Results : Cronbach's alpha of all Index except WOMAC stiffness subscale(.6679) exceeded the value of 0.70. A good correlation was obtained between WOMAC Subscale (especially Pain Subscale) and LFI (.726<cronbach's alpha<.791). Also, Correlation between KHAQ and two disease-specific questionnaires (WOMAC and LFI) was good(.612<cronbach's alpha<.662). Conclusions : All used instruments have good internal reliability. also, There are good correlation among them. The treatment of knee OA must be focused on health related quality. For this, we should use proper assessment instruments.

Microstructure and piezoelectric properties of the lead-free (1-y)wt% [99.5wt%{0.96(Bi_(0.5)(Na_(0.84)K_(0.16))_(0.5)TiO₃)+0.04(SrTiO₃)}+0.3wt%(Nb₂O_(5))+0.2wt%(La₂O₃)] ceramics (BNKTSNL) were investigated as a function of the amount of y wt% MnO2 addition. Both the density and the grain size of the BNKTSNL ceramics increased with increasing the MnO₂ addition. In other words, MnO₂ improved the sintering properties of the BNKTSNL ceramics. Both the electromechanical coupling factor (kp) and the dielectric constant decreased and showed the minimum value of 33.6% and 874 with 0.3wt% MnO₂ addition, respectively. However, the mechanical quality factor(Qm) showed the maximum value of 150 with 0.3wt% MnO₂ addition. The effects of the MnO₂ addition on the piezoelectric properties of BNKTSNL ceramics could be explained in terms of the hardener manganese element.
