오늘날 국내 외의 경제발전에 서비스산업의 비중이 매우 커지고 있으며, 미래사회에도 지속적으로 증가될 것으로 예측되며, 이러한 서비스 산업의 경영방식의 하나로 프랜차이즈시스템이 확산되고 있다. 프랜차이즈 시스템(Franchise System)은 선진국에서 인기를 끌고 있는 선진국형 유통형태이며, 유통시장 개방 이후 국내에서는 외국유명브랜드를 중심으로 급속한 성장세를 보이고 있다. 이로 인해 국내 제조 및 유통업계에서는 미래유망업종으로 프랜차이즈시스템에 대한 관심이 커지고 있다. 최근 들어 외환위기와 금융위기를 계기로 다양한 연령계층이 노동시장으로 유입되면서 단기간 내에 적은 자본으로 나의 사업을 창업하고자 하는 인구가 크게 늘고 있다. 이 중 상당수는 독립적 사업을 창업하지만 사업에 대한 경험과 전문지식이 부족하면서 실패를 경험하는 경우가 크게 늘고 있다. 이에 비해 프랜차이즈 창업은 검증된 상품 및 서비스를 제공받으면서 창업한다는 점에서 성공가능성이 높아지면서 프랜차이즈에 대한 관심과 논의가 증가하고 있다. 그러나 프랜차이즈에 대한 관심이 증대하고, 프랜차이즈 산업의 규모가 커지면서 다양한 문제점 또한 부상하고 있다. 국내의 경우 비교적 늦게 프랜차이즈 산업이 도입되었지만 빠르게 성장하면서 문제점을 노정하고 있는 것이 현실이다. 이에 본 논문에서는 프랜차이즈 산업의 특성에 대하여 고찰하고, 또한 다른 나라들의 경우에 대한 사례를 고찰하면서 국내 프랜차이즈 산업의 문제점을 조명하고 이에 대한 대응방안 및 프랜차이즈 산업의 발전방안을 제시하고자 하였다.

The purpose of this research is to conserve of golden decoration(Jikgeumdan) of Chima(skirt) and Jeogori(Korean jacket) of the costumes excavated from Hangju Gi' tomb(17th Century) of Joseon dynasty$(1392{\sim}1910)$ and to focus on the development of conservation skill to prevent flakings of gold leaves in gilt paper strips. Up to the present, in case of golden decorations of costumes excavated from tombs of Joseon dynasty, some of gold leaves in gilt paper strips of costumes were flaked away by deterioration of adhesives in tombs. However, most of gold leaves were flaked away and totally lost by wet cleaning for eliminating contaminants after excavation. In order to prevent flaking, preliminary experiments for re-adhesion of gold leaves have been carried out. Firstly, simulation was performed using gold leaf which was available in the market. Adhesives used in this research were water-soluble adhesives(hide glue(cow, rabbit), glue made from air bladders of sciaenoid fish and Primal AC-3444 of acrylic emulsion) and solvent-soluble adhesives(acrylic adhesive Paraloid B-67 and B-72). Because of difficulty in wetting and spreading of adhesive solutions into the interface between gold leaf and Korean paper, water-soluble adhesives were not proper for adhesion of gold leaf and Korean paper. Solvent-soluble adhesives were easily infiltrated into interface between gold leaf and Korean paper and the adhesive force was also satisfied. From this result, the researchers chose more flexible Paraloid B-72$(Tg\;40^{\circ}C)$ 1% solution than Paraloid B-67$(Tg\;50^{\circ}C)$ for adhesion of gold leaf and Korean paper. Secondly, using Paraloid B-72 1% solution, the estimations of re-adhesions of gold leaves in gilt paper strips of Jeogori were carried out. When Paraloid B-72 1% solution was injected three times into the interface between gold leaf and Korean paper, the re-adhesion was most effective. On the basis of the results in these preliminary experiments, re-adhesions of gold leaves in gilt paper strips of Chima and Jeogori were carried out on condition of three times injections of Paraloid B-72 1% solution before wet cleaning. After wet cleaning, the most of the gold leaves were survived, which was confirmed by both the examination with the naked eye and the microscopic examination.

Field trials evaluating selected commercially available mosquito traps variously baited with light, carbon dioxide, and/or octenol were conducted from 18-27 September 2000 in a malarious area near Paekyeon-ri (Tongil-Chon) and Camp Greaves in Paju County, Kyonggi Province, Republic of Korea. The host-seeking activity for common mosquito species, including the primary vector of Japanese encephalitis, Culex tritaeniorhynchus Giles. was determined using hourly aspirator collections from a human and propane lantern-baited Shannon trap doting hours when temperatures exceeded $15^{\circ}C$. The total number of mosquitoes and number of each species captured during the test was compared using a block design. Significant differences were observed for the total number of mosquitoes collected, such that, the Mosquito MagnetTM with octenol > Shannon trap > ABC light trap with light and dry ice > Miniature Black Light trap (manufactured by John W. Hock) $\geq$ New Jersey Trap > ABC light trap with light only. Significant differences in numbers collected among trapes were noted for several species including: Aedes vexans (Meigen), Anopheles lesteri Baisas and Hu. An. sinensis Weidemann, An. sineroides Yamada, An. yatsushiroensis Miyazaki. Culex pipiens pallets Coquillett L., Cx. orientalis Edwards and Cx. tritaeniorhynchus. Host-seeking activity for most common species showed a similar bimodal pattern. Results from these field trap evaluations can significantly enhance current vector and disease surveillance efforts especially for the primary vector of Japanese encephalitis, Cx. tritaeniorhunchus.

드론은 처음에 공군기나 미사일 연습 사격 표적용으로 개발되었으며, 일반인들에게는 무인 항공기 전체를 의미하는 것으로 사용되고 있다. 드론의 핵심 개념은 '무인'과 '항공기'로 구분될 수 있다. 그러나, 융합과학 기술혁명으로 표현되는 제 4차 산업혁명은 새로운 도시 공간형성의 개념으로 스마트시티가 제안되고 있으며 새로운 도시내 통합이동 체계 내에서 드론을 포함한 자율주행 이동체의 역할이 강조되고 있는 시점에서 기존의 드론 개념이 과연 적합한지에 대해서는 여러 의문이 제기되고 있다. 본 연구에서는 기존의 드론의 개념에 대하여 발전과정과 각국의 법률상 정의, 선행연구 결과 등을 분석하여 미래 사회에 적합한 개념과 통일적인 용어를 제시하고자 하였다. 시대적 상황에 따라 국가나 기관, 또는 운용주체의 목적에 따라 드론을 정의하는 것은 바람직하지 않다. 인간의 삶에 바탕을 두고 드론의 개념을 인간의 도시 생활에서 찾아내는 것이 기존의 방법보다는 보다 합리적이며, 앞으로 드론의 발전상황을 고려한다면 더욱 타당하다고 할 수 있다. 후속연구에는 보다 상세하고 더 많은 자료와 연구결과 등을 분석하고, 본 연구에서 다루지 못한 부분에 대해서도 논의를 진행해야 할 것이다. 이를 바탕으로 법제화, 운영규정 마련, 관련 산업 진행 및 규제 등 다양한 주제에 대해서도 연구가 되어야 할 것이다.

This is a research for thickness change of denture base according to the shape of sprue & investment position of denture base in flask when injecting polyamid base resin for flexible partial denture as a part of study for Valplast among the flexible partial denture with a nylon base. It has been introduced several kinds of flexible partial denture product with a nylon base, but Valplast is the most widely used product among them. Valplast has been the most generally used material today since developed in 1950s in the United States as a material for flexible partial denture. Valplast is much more aesthetic than general metal-acrylic partial denture due to its translucent pink color and biocompatibility in terms of material characteristic. It keeps its flexibility for a long time after production, imposes a less burden on the teeth used as abutment, and it can be easily insert and remove due to its particular suppleness. Moreover, it is felt like real teeth more than metal-acrylic partial denture when being put in and takes alveolar bone under good protection since it receives occlusal force equally under the denture base. The most outstanding feature of Valplast is flexibility. The extent of its flexibility is determined by width & thickness of denture base. Considering general working procedure of Valplast, it can be seen that the thickness of denture base formed out of wax is increasing by the pressure while injecting resin. This research is to decide and test on the thickness increasing of Valplast by injecting pressure and the hypothesis upon that and is to prepare the basis estimating the increasing extent of thickness of denture base on the basis of the test result. In this test, it is expected occlusal malposition & thickness increasing of denture base by injecting pressure according to 4 kinds of test data which are to select 3 types of sprue method settling the forefront position at which the test material of fixed standard can be invested and to position the test material at the rearmost part keeping the minimum distance to set sprue. For 4 kinds of injecting test by investment position & sprue type, 20 test materials, 5 for each test were produced and a pressure of 1,180Kg was given with automatic injector of air cylinder type. The results are as follows: 1. For the amount of thickness increasing of denture base by investment position, the thickness of front investment is less increasing than the one of rear investment. 2. For the amount of thickness increasing of denture base by sprue type, the thickness of straight decompression sprue type which can absorb the injecting pressure after injecting polyamide base resin is less increasing than the other sprue types.

High cognitive workload decreases a driver's ability of judgement and response in traffic situation and could result in a traffic accident. Electrocardiography (ECG) has been used for evaluation of drivers' cognitive workload; however, individual differences in ECG response corresponding to cognitive workload have not been fully considered. The present study developed an evaluation method of individual driver's cognitive workload based on ECG data, and evaluated its usefulness through an experiment in a driving simulator. The evaluation method developed by the present study determined the optimal ECG evaluation condition for individual participant by analysis of area under the receiver operating characteristic curve (AUC) for various conditions (total number of conditions = 144) in terms of four aspects (ECG measure, window span, update rate, and workload level). AUC analysis on the various conditions showed that the optimal ECG evaluation condition for each participant was significantly different. In addition, the optimal ECG evaluation condition could accurately detect changes in cognitive workload for 47% of the total participants (n = 15). The evaluation method proposed in the present study can be utilized in the evaluation of individual driver's cognitive workload for an intelligent vehicle.

Background: Breast cancer (BC) is the most-common malignancy of women worldwide. Though there are differences among developed and developing countries, BC remains the most common cancer type of women in Turkey. Objective: This study aimed to identify the level of knowledge, awareness, and their potential predictors towards BC in Ankara, Turkey. Materials and Methods: The present descriptive study was conducted on 376 females attending a breast health outpatient clinic. A self-administered questionnaire was designed to evaluate knowledge level about BC and predictors effecting its level. Data analysis was performed using the chi-square test. A value of p<0.05 was considered statistically significant. Results: Mean age of the participants was $46.2{\pm}9.93$ (22-75). The majority (92.6 %) were married; 41.5% were educated less than nine years. Most of the women were housewives (82.7%) and, were living in an urban region (86.4%). Predictors of effecting responses to seven knowledge and awareness questions about BC varied from demographic features including older age groups, higher educational levels, being married, living in an urban area, being employee, smoking, having greater BMI to additional attributes associated breast health such as the increased number of births, applying for the purpose of control, positive family history of breast diseases, any diagnoses of breast diseases and performing BSE practice. Conclusions: It was determined that females in Turkey have better knowledge of BC than other developing countries even though it is not at the desired level. These findings revealed that females should be more informed about BC risk factors, prognosis and treatments by primary health-care providers to counteract the ascending burden of this disease.
