본 연구는 결혼이주 베트남 여성들의 완전모유수유 실천 기간 및 관련 요인을 파악하여 추후 이들의 모유수유실천 증진을 위한 교육프로그램 개발 시 기초자료로 활용하기 위한 목적으로 실시하였다. 서술적 조사연구로, 대전, 충남지역에 거주하고 있는 결혼이주 베트남 여성 중 생후 6개월 이상 5세 이하의 자녀를 둔 125명을 대상으로 구조화된 질문지를 이용하여 면접법에 의해 자료를 수집하였다. 수집된 자료는 빈도와 백분율, t-검정, ANOVA 및 단계별 다중회귀분석을 이용하여 분석하였고, 결과는 다음과 같다. 첫째, 결혼이주 베트남여성의 완전모유수유 실천기간은 평균 15.9주 이었다. 둘째, 생후 6개월간 아기의 월령이 증가됨에 따라 완전모유수유 실천율은 감소하고, 분유수유와 혼합수유가 증가하였다. 셋째, 완전모유수유실천 기간에 영향을 미치는 요인은 가족형태, 모유수유 교육유무였으며, 이들 변인의 설명력은 30.8% 이었다. 이상의 연구결과 모유수유 교육유무가 완전모유수유 실천에 중요한 예측요인임을 확인할 수 있었다. 그러므로 결혼이주 베트남 여성의 완전모유수유 실천기간 증진을 위한 체계적인 교육프로그램 개발과 그 효과를 검증하는 후속 연구의 필요성을 제언한다.

현재, 국내 CNC 산업분야는 제조업의 패러다임 변화에 따라 공작기계에 첨단 기술의 적용이 활발하게 추진되고 있다. 즉, 공작기계의 제어를 담당하는 CNC의 IT화는 가장 중요한 부분을 차지하고 있다. 하지만 공작기계 분야에 모션제어 전문기술 부족의 가장 큰 이유는 PC기반의 컨트롤러의 경우 비중을 많이 차지하는 윈도우즈 언어를 사용하기 보다는 G-Code를 직접 좌표에 맞춰 코딩하거나 값비싼 외산 S/W를 통해 변환 하는 경우가 대부분이기 때문이다. 본 논문에서는 다양한 형태의 CAD 데이터를 손쉽게 G-Code 데이터로 변환할 수 있는 G-Code 변환 프로그램 및 CAD&CAM과 응용 소프트웨어를 개발하고 이 변환된 데이터를 바로 로봇을 통해 원하는 동작을 시킬 수 있는 전용 모션 컨트롤러를 구현한다.

In this paper, a new fragile watermarking algorithm for digital image is presented, which makes resolving the security and forgery problem of the digital image to be possible. The most suitable watermarking method that verifies the authentication and integrity of the digital image is the Wong's method, which invokes the hash function (MD5). The algorithm is safe because this method uses the hash function of the cryptology. The operations such as modulus, complement, shift, bitwise exclusive-or, bitwise inclusive-or are necessary for calculating the value of hash function. But, in this paper, an Arithmetic encoding method that only includes the multiplication operation is adopted. This technique prints out accumulative probability interval, which is obtained by multiplying the input symbol probability interval. In this paper, the initial probability interval is determined according to the value of the key, and the input sequence of the symbols is adjusted according to the key value so that the accumulative probability interval will depend on the key value. The integrity of the algorithm has been verified by experiment. The PSNR is above the 51.13db and the verifying time is $1/3{\sim}1/4$ of the verifying time of using the hash function (MD5), so, it can be used in the real-time system.

In this paper a method to perform Exclusive-OR operation between two tabular type Boolean expressions is presented. The proposed method allows to solve the switching equations and the simultaneous equations in a rather direct manner, compared with Unger's method.

Purpose - The purpose of this study was to clarify the factors to make an exclusive importation contract between foreign fashion brands and local retailers for successful business in Korea. Even though imported fashion brand market shows stead increasing in terms of sales amount, the number of store related study was very rare in fact. Meanwhile, as long as this business is glowing a lot of brands are suffering from bad business performance or getting in ruins thus these problems result in foreign currency loss. The local marketers therefore, strongly expect to know the solution for this matter. Research design, data, and methodology - For the qualitative research, 10 experts who are operating foreign brands with an exclusive contract at a department store or at duty free shop now and who had at least over 10 years of related working experience were included. The factors for the exclusive importation contract with foreign brands were drawn up through the one-to-one in-depth interview method from September 3, 2017 to January 15, 2018. The expert group for the validity analysis includes 2 professors and 5 postgraduate students. Results - As a result of qualitative study on the factors for imported fashion brand's launching with the exclusive importation contract, it turned out that there were 5 factors - safety, profitability, reliability, speed and global retailing. Safety, profitability, and reliability have been mentioned in most related surveys but some details are added and speed and global retailing have been newly highlighted and many unknown legal issues that it was not easy to get form common academic research are included. Speed simply means quick lead time and global retailing means stores where located in other countries. Conclusions - The reason that qualitative research should be done before the quantitative research is due to the scant theoretical background for this matter. Because the market of an imported fashion brand is steadily increasing, determining the factors to make exclusive importation contract is very meaningful from the point of academic and business. After this study, many marketers may get basic conditions to apply for real business and I hope the following quantitative research will give more effective results. The next study also will have extended range concerning industry area, product and distribution channel.

본 연구는 수 위탁거래의 전속성이 수탁 중소벤처기업의 R&D투자, R&D인력, 외부 조직과 협력 범위, 특허출원건수, 신제품에 의한 매출 및 누적 매출성장률에 미치는 영향을 분석한다. 벤처기업정밀실태조사의 원자료를 이용하여 6,029개 중소벤처기업의 병합된 횡단면 데이터를 분석한 결과 첫째, 대기업 및 1 2차 협력업체와 전속거래를 하는 중소벤처기업의 R&D투자수준은 시장판매 중소벤처기업의 투자수준보다 낮음을 실증하였다. 둘째, 전속거래를 하는 중소벤처기업의 혁신활동, 즉 R&D인력 비율 및 외부 조직과 협력 제휴 범위는 시장판매하는 중소벤처기업에 비해 낮음을 확인하였다. 셋째, 전속거래를 하는 중소벤처기업의 혁신성과, 즉 특허출원건수, 신제품에 의한 매출비중, 누적매출성장률은 시장판매하는 중소벤처기업에 비해 모두 낮음을 검증하였다. 네 번째로 수탁 중소벤처기업이 위탁 대기업의 1 2차 협력업체와 전속거래를 하는 경우가 가치사슬 상위의 대기업과 전속거래를 하는 경우에 비해 혁신 투입, 활동, 성과의 모든 측면에서 낮은 성과를 보이고 있었다. 위탁대기업 또는 1 2차 협력업체와 전속거래여부는 중소벤처기업의 혁신프로세스를 전반적이고 체계적으로 약화시켜서 혁신을 통한 성장을 기대하기 어려운 일종의 시장 실패를 가져오므로 중소벤처기업의 혁신정책은 이를 반영하여 설계될 필요가 있다.

One mid-esophageal carcinoma underwent esophagogastrectomy using an exclusive right thoracic approach entailing mobilization of the stomach through the esophageal hiatus. 62 year old male farmer was admitted with chief complaints of dysphagia and weight loss of 5 Kg. for 6 months, and regurgitation after soft meal for one week prior to this admission. Preoperative esophagogram revealed stricture with fungating mass at the level of the carina, which was diagnosed as squamous cell carcinoma at the time of esophagoscopic biopsy about 33 cm from incisor. Bronchoscopy revealed no invasive lesion or carinal fixation, and laboratory examinations were excellent for operative intervention. An exclusive right thoracic approach through right 5th rib bed was made for radical esophagectomy, mobilization of the stomach through the esophageal hiatus and primary esophagectomy. Postoperative recovery was uneventful except increased bronchial secretion due to senile emphysema, and follow up for 5 months after esophagectomy revealed good functioning esophagus with mild epigastric fullness after meal. Exclusive right thoracic approach for radical esophagectomy seems to be the procedure of choice in selected cases.

This study aimed to clarify the difference between consumers and hands-on staff in evaluation of the attributes importance of asset evaluation attributes and the relationship between difference from consumers and hands-on staff in evaluation of the attributes and the performance. Subjects for the quantitative research, quota sampling was adopted in the areas where the subject brands were in place, and 452 questionnaires (141 of hands-on staff, 311 of consumers) were analyzed. The results were as follows; 1. The factors that hands-on staff and consumers regarded as most important as to asset evaluation attributes of department store-exclusive importation brands included preference and product quality in the order, and then image, recognition, reliability, and country of origin in the case of hands-on staff, and reliability, image, recognition, and country of origin in the case of consumers in the order. 2. As a result of examining the effect of the difference between hands-on staff and consumers regarding exclusive importation brands(GAP, ZARA) of certain department stores on business achievement and consumer attitude, it turned out that the smaller the difference between the two groups with regard to evaluation, the higher the business achievement and consumer attitude.
