유광의 Loughborough University of Technology 1995 해외박사

본 논문은 우리나라 국제항공 여행자의 비행선택 행동을 연구하였다. 특히 비행시간이 10간 이상되는 장거리 여행자의 비행선택 행동을 대상으로 했다. 소비자의 행동을 연구하기 위해서는 Disaggregate 데이타를 이용하는 것이 효 과적인데 전통적으로는 교통시장에서 관찰된 Revealed Preference 데이타가 교통소비자 행동 연구에 사용되었었다. 그러나 Revealed Preference(RP)데이 타의 한계성 때문에 Stated Preference(SP)데이타의 이용이 대두되었다. 그러나 SP데이타는 소비자의 진술을 토대로 얻어지므로 신뢰성에 의문을 제기 하지 않을 수 없다. 따라서 가장 이상적인 방법은 RP와 SP 데이타의 동시 이용일 것이다. 본 논문도 한국인 국제항공 여행자의 비행선택 행동을 연구함 에 있어 RP와 SP 데이타를 동시에 이용하였다. 필요 데이타는 김포공항 여객터미널에서 실시한 설문조사로 수집되었다. 먼저 RP데이타를 수집. 분석하여 현실시장에서 드러난 선택행동의 일반적 특성 을 파악하고 효용함수를 도출했다. 분석결과, 동시장에서 소비자가 장거리 국제항공여행을 위한 비행선택시 주요하게 고려하는 변수가 항공요금. 항공 여행소요시간, 운항빈도, 항공사의 국적(한국국적 또는 외국국적) 임이 밝혀 졌다. RP 데이타 분석 결과를 토대로 SP의 가상 대안이 작성 되었고, SP 설 문조사도 김포공항에서 실시되었으며 SP 효용함수가 도출 되었다. RP 데이타의 분석에서 드러난 동 시장에서의 비행선택의 일반적 특성, RP효 용함수, SP 효용함수를 상호보완 및 비교. 분석한 결과 다음과 같은 것들을 밝힐 수 있었다. .여행자의 시간가치(Value of travel time: VOT) . 한국국적 항공사에 대한 추가 부담가치 . 운항횟수의 가치 . 운항빈도와 항공여행시간의 대체율 . 국적과 여행시간의 대체율 본 연구는 RP와 SP 데이타의 동시저용을 항공교통분야에 처음 적용하여 그 효용성을 입증하였고, 비교분석시 RP모델과 SP모델이 보여준 차이점이 존재 함을 인정하여 적절한 해석을 가했다.

The component analysis of buckwheat powder and buckwheat noodles(extruded, raw, and dried noodles) which are mixtures of wheat flour and buckwheat powder, dough properties of the mixtures of wheat flour and buckwheat powder, and physical properties of buckwheat noodles were investigated. 70% ethanol extracts of buckwheat noodles were prepared and were subjected to in vitro and in vivo testing to explore their physiological activities including antioxidative, antimutagenic, anticancer, and hyperlipidemic effects. Finally, qualities of buckwheat noodles were examined in terms of various items during storage periods. These results may be the fundamental data for an improvement of the function of buckwheat noodles. All the results could lead to the following conclusions: The component analysis of buckwheat powder and buckwheat noodles(extruded, raw, and dried noodles) which are mixtures of wheat flour and buckwheat powder, dough properties of the mixtures of wheat flour and buckwheat powder, and physical properties of buckwheat noodles were investigated. 70% ethanol extracts of buckwheat noodles were prepared and were subjected to in vitro and in vivo testing to explore their physiological activities including antioxidative, antimutagenic, anticancer, and hyperlipidemic effects. Finally, qualities of buckwheat noodles were examined in terms of various items during storage periods. These results may be the fundamental data for development of functional buckwheat noodle. All the results could lead to the following conclusions: 1. The component analysis of buckwheat powder and the mixtures of wheat flour and buckwheat powder Analysis of the general composition of buckwheat powder, and the mixture of wheat flour and buckwheat powder, demonstrated that the increase of buckwheat powder in the mixture caused slight elevation of crude ash, crude fat, and crude fiber content but slight decrease of crude protein, sugar, and energy. In the analysis of fatty acids, the content of palmitic acid was independent of a buckwheat ratio in the mixture and stearic acid was the most abundantly in the mixture of 80% buckwheat powder. However, the content of linoleic, linolenic, arachidonic, and behenic acids were slightly elevated by the increase of the buckwheat ratio in the mixture. The content of linoleic and eicosapentaenoic acid were increased by the decrease of the ratio of buckwheat in the mixture. 2. The component analysis of buckwheat noodles The general composition of noodles from the mixtures of 60% and 70% buckwheat powder revealed that the content of crude fat and crude protein in raw noodles was higher than that in the extruded noodle but carbohydrate content of raw noodles was low. The mineral content of noodles from the mixtures with 60% and 70% buckwheat indicated that calcium content was higher in dried noodles than that in raw and extruded noodles, but the phosphorous content was highest in an extruded noodles and then followed by dried and raw noodles. The iron content was the highest in dried noodles, and dried and extruded noodles had similar sodium content. The fatty acids content in noodles from the mixture of 60% or 70% buckwheat was analyzed that the palmitic acid content of dried and extruded noodles from the mixture of 60% buckwheat was high and linoleic acid content of raw and 60% buckwheat noodles was high. Arachidonic acid and eicosapentaenoic acid contents in noodles from the mixture of 60% buckwheat were high. 3. Thermal properties The gelatinization temperature and the viscosity were elevated with the increase of a buckwheat ratio in the mixture. The initial gelatinization temperature and highest viscosity were gradually lowered with the decrease of a buckwheat ratio. 4. Rheological properties of dough The rheological properties were analyzed and the results showed that development time of dough increased with reduction of the buckwheat ratio in the mixture. The analysis for the dough stability and weakness shows that these properties were independent of buckwheat ratios in the mixture. 5. Color evaluation of buckwheat noodles The measurement of color change showed that lightness(L) values for a raw noodle elevated with the increase of buckwheat ratio in the mixture, but redness(a) and yellowness(b) values were not changed. For an extruded noodle, L, a, and b are independent of buckwheat content. L value of a dried noodle was higher than that in extruded and raw noodles. The a value for dried noodles is similar to that for a raw noodle, and the b value for dried noodles was in the middle of the values of those for extruded and raw noodles. 6. Crushing strength of buckwheat noodle The strength of noodles was slightly increased with a decrease of buckwheat ratio in the mixture, and the total energy was decreased with the increase of buckwheat ratio in the mixture. The expanded length on the expansibility was decreased with the increase of buckwheat ratio in the mixture. Therefore, an increase of the expanded length and high tension level were caused by a decrease of buckwheat ratio in the mixture. 7. Preparation of buckwheat noodles extracts and determination of the extraction yields The extraction yields were highest in raw noodles containing 60% buckwheat powder, and dried noodles containing 60% buckwheat powder, raw noodles containing 70% buckwheat powder, and extruded noodles containing 70% buckwheat powder were subsequently followed in the order of their extraction yields. 8. Radical-scavenging activity of extract of the mixtures containing wheat flour and buckwheat powder against stable DPPH(1.1 diphenyl-2-picryl radical) was determined. The RC50 value (concentration of extract causing 50% inhibition of absorbance) for each mixture’s extracts was calculated indicated that the extract of the mixtures containing 70% buckwheat powder was higher than that of the mixtures containing 60% buckwheat powder. 9. The cells viability was assayed by the sulphorhodamine(SRB) method after cultured human cancer cells were treated with the extract of the mixtures containing 100, 60 or 70% buckwheat powder. The extracts of the highest concentration(1 mg/mL) revealed reduction of cell viabilities of 61.2%, 67.9%, and 65.5%, respectively, when treated to the human non-small lung cancer A549 and those of 74.9%, 74.5% and 81.1% respectively when treated to the human gastric adenocarcinoma AGS cells. Especially, 70% buckwheat powder extract reduced more cells viability than other extracts. The extracts showed growth inhibition effects of 72.9%, 69.3%, and 64.6%, respectively when treated to human cervical cancer HeLa cells. The growth inhibitions of human breast cancer MCF-7 cells treated with extracts of the mixtures containing 100, 70 or 60% buckwheat powder were 67.9%, 63%, 58%, respectively and the growth inhibitions of human liver cancer Hep3B cells treated the extracts were 72.6%, 63.5%, 49.8%, respectively. However, the growth inhibitions in normal cells were lower than 40% when compared those in cancer cells. The results suggested that the extract of the mixtures containing buckwheat powder had strong cytotoxic properties in cancer cells but low cytotoxicity in normal cells. 10. Cell survival of cultured the human cancer cells after exposure to extracts of raw noodles containing 60% of buckwheat powder by using the SRB cytotoxicity assay demonstrated that the extract had high cytotoxicity in liver, lung, and gastric cancercells but low in breast cancer cells. The extracts of rawnoodles containing 70% of buckwheat powder had high cytotoxicity in uterine and human liver cancers cells. The extracts of extruded noodles containing 60% of buckwheat powder had high cytotoxicity in gastric, lung, and uterine cancer cells. The all extracts had high cytotoxicity especially in lung and gastric cancer cells, but the cytotoxicity in normal cells(293) was low. The results provided supportive data for the anticancer potentials of buckwheat noodles. 11. The antimutagenic effects of the extract of the mixtures containing 100, 70 or 60% buckwheat powder against N-methyl-N’ -nitro-N-nitro-guanidine(MNNG) and 4-nitroquinoline-N-oxide (4NQO), which is a direct mutagen on Salmonella typhimurium strains TA100 and TA98, were examined. With S. typhimurium stain TA100, the extract of the mixtures containing 100, 70 or 60% buckwheat powder showed the inhibitory effects of 45%, 37.3%, and 42% on the mutagenesis of MNNG(0.4 ㎍/plate), respectively, and of 44.3%, 36.4%, 22.1% on the mutagenic effects of 4NQO(0.15 ㎍/plate), respectively. When the mutagens of 160 ㎍/plate were treated to S. typhimurium strain A98, extracts showed the inhibition rates of 64%, 47.1%, 38.2%, respectively. 12. Extracts(0.4 ㎍/plate) of raw noodles containing 60% and 70% of buckwheat powder had great antimutagenic effects(0.4 ㎍/plate) against MNNG, whereas they had low antimutagenic(0.15 ㎍/plate) against 4NQO. The 60% raw buckwheat noodles were more effective in antimutagenic activity than that of 70% raw buckwheat noodles. In the case of extruded noodles, the extracts of 60% and 70% buckwheat powder showed antimutagenic activities of S. typhimurium strain TA100 against MNNG(0.4 ㎍/plate) and 4NQO(0.15 ㎍/plate), which were less antimutagenic than other extracts. 13. There were no significant differences in mutagenicity on the extracts of extruded and raw noodles containing 60% of buckwheat powder. 14. The study is to investigate the in vivo antitumor activity of 100% buckwheat power, 60% buckwheat power, raw, extruded, and dried noodles containing buckwheat powder against Sarcoma-180 cells transplanted in mice. In vivo growth-inhibition of Sarcoma-180 tumor in 100% buckwheat power-treated groups was 57.7% and those in 60% buckwheat power, raw, extruded, and dried noodles containing buckwheat powder-treated groups were 60, 60, 60, and 60%, respectively. The results showed that antitumor activity was higher in all treated groups compared with the control group. 15. We measured the body weight to investigate the effect of buckwheat noodleson lipid metabolism. As a result, rats fed with high fat diet had higher body weight gains than those of rats fed with a normal diet. On the other hand, the body weight was reduced by buckwheat administration in all groups when compared with high fat control group. 16. The rats were fed with high fat diet containing extracts of buckwheat noodles for 4 weeks and then changes in heart, kidney, liver and spleen weights were measured. As a results, the weights of those were not significantly different among groups fed buckwheat noodles whereas the control group fed high fat diet had higher liver and kidney weights than those of other groups. The rats fed buckwheat with a high fat diet had lower liver and kidney weights than those of rats fed high fat diet. After 4 weeks of administration with extruded noodles containing 60% buckwheat powder, the liver weight was decreased dramatically while the liver weight resulted in similarly weight of the rats fed normal diet. This result suggested that extruded noodles containing 60% buckwheat powder might be good for prevention of fat accumulation in the liver. The kidney weight of the groups fed with the extruded noodle containing 60% buckwheat powder showed the lowest value. 17. The serum cholesterol level was reduced in rats fed the high fat diet combined with extruded noodles containing 60% buckwheat powder when compared with high fat diet group with no extruded noodles. Rats fed high fat diets had low levels of serum HDL cholesterol when compared with that in rats fed normal diets. Normal diets group had high levels of serum HDL cholesterol. HDL cholesterol level was mildly increased in rats fed the high fat diet with buckwheat noodles when compared with that in rats fed high fat diet but was not significantly increase. However, serum triglyceride level was significantly decreased in rats group fed with the high fat diet combined with buckwheat when compared with those with the high fat diet group with no buckwheat. 18. The propagation of E. coli and other germs in extruded, raw, and dried noodles containing 60% buckwheat powder was observed after storing periods at several storing temperatures. As a result, E. coli was not found in all types of noodles stored at 4, 25, and 35℃, respectively. And there was no change in the germ count at 4℃ for 20 days. Therefore, the raw noodles could be commercially circulated(or distributed) for 8 and 15 days at room and higher temperatures, respectively, thus, extruded, raw, and dried noodles containing 60% buckwheat powder may be stored or distributed at low temperature for 20 days without any hygienic problems. Other than a bad odor that was emitted from raw noodles on the 12th day after storing at 35℃, no odors and no fungus were found in all types of noodles regardless of storing temperature. These results suggest that nutritional noodle properties were significantly higher in the mixture containing 60% buckwheat powder compared to the other mixtures containing buckwheat powder, thus, we further investigated its beneficial effects. Its noodle using the mixture containing 60% buckwheat powder showed improved antioxidative, antimutagenic, anticancancer, and hyperlipidemic effects compared to the control group. Taken together, it was demonstrated that a product of noodle manufactured with the ingredient of 60% buckwheat powder is most compatible in nutritional quality and noodle texture as well as a cost.

This study analyzed affection of foreign residents who stay for a long time on local economy growth in circumstance that lowering the international migration’s barrier and change of domestic industrial and population structure. The residents are classified, by their aims of entry, as 4 groups, those who like workforce, professionals, students, marriage migration and settler, and etc. The distribution of them shows distinctions clearly by regional characteristics. As for local economy growth, the foreign residents play a role as reducing cost of the elements of production through supplying of cheaper labor, taking leads in regional innovation as creative talented persons, through making tolerant social atmosphere, expansion of local consumer market. However, they also may come into conflict with domestic residents or replace domestic job occupation with themselves. So, When it comes to measuring affection of the foreign as for local economy growth, we ought to consider both the right function and the reverse of them. In the result of the regression analysis, entirely the professional, the workforce and positively affected the local economy growth, However, the students did not affect the local economy growth. In the case of rural area, the marriage immigrants positively affected the local economy growth. As for interpretation of the result, we can presume the cause of the professional’s higher influence, and also presume the students’s neutral affection results from that the loss of their replacement of domestic worker’s part time job as much as their consumption in their local region. Eventually, the difference of analysis result for marriage migration and settler in metropolis and rural municipality results from difference of soundness of employment opportunities in two different region and their husbands’s ability to maintain their livelihood. 본 연구는 세계화의 진전에 따른 국가 간 이동 장벽의 하향화와 국내 산업 및 인구구조의 변화에 따라 국내에 장기체류하는 외국인 주민이 지속적으로 증가하는 상황 속에서, 이들, 장기체류 외국인 주민 유입이 해당 지역총생산으로 측정되는 지역경제발달에 줄 수 있는 영향을 계층별 특성을 반영하여 분석하였다. 외국인 주민은 그들의 입국 목적에 따라 단순기능 인력, 전문 인력, 결혼이주 및 영주 목적의 외국인, 유학생, 기타로 구분될 수 있는데, 지역의 성격에 따라 각 유형의 외국인들의 분포에 차이를 보이고 있다. 외국인 주민은 지역경제에 있어, 값싼 노동력 제공을 통한 생산요소비용절감, 핵심적 창조 인재로서의 혁신의 주도, 다양하고 관용적인 사회분위기 형성을 통한 지역사회의 문화 융성, 소비를 통한 지역시장규모의 확대의 역할을 할 수 있지만, 지역 주민들과의 갈등을 야기하거나 내국인 인력의 고용을 대체하는 역기능을 할 수도 있어, 지역경제력에 대한 외국인 주민의 기여도를 측정할 때에는 그 순기능적 측면과 역기능적 측면을 모두 고려하여야 한다. 본 연구에서는 외국인 출입국 정책본부와 통계청의 각종 지역 통계자료를 바탕으로 하여, 2005년 외국인 고용허가제가 시행되고, 2007년 재외동포를 대상으로 한 방문 취업제가 시행되면서, 출입국 관련 정책의 틀이 완성된 2008년 이후 기초지자체 단위의 경제통계의 구득이 가능한 최신년도인 2010년 자료를 대상으로 하여, 특성별 외국인 주민의 수와 함께 지역경제력의 발달에 영향을 줄 수 있는 인구 특성, 생활환경과 산업기반의 사회간접자본 특성, 지역의 기존 경제력 특성, 집적 경제특성, 혁신창출 역량특성에 해당하는 변수들을 통제변수로 고려하여 다중회귀분석을 실시하였다. 분석은 매 모형마다 동일한 변수를 투입하되, 지역별 특성을 더미변수를 통해 모형에 반영하였으며, 변수 간 상관성을 고려하여, 일부 변수에 한해 별도의 모형을 구성하였다. 분석결과, 전체적으로 전문 인력과 단순 기능 인력 외국인 주민이 지역경제발달에 영향을 주는 것으로 나타났으며, 유학생의 경우 별다른 기여를 하지 못하는 것으로 나타났고, 결혼이주 및 영주 목적 외국인의 대도시에서의 지역경제 발달에 대한 영향은 유의미하지 않았지만, 농촌지역에서는 가장 큰 기여를 하는 것으로 나타났다. 유학생 외국인의 영향 유의미하지 않은 것은 그들의 소비시장 확장에 대한 기여도에 상응할 만큼 내국인의 비정규 시간제 일자리를 대체함에 따른 영향이 큰 것으로 추정할 수 있으며, 결혼이주 및 영주 목적 외국인 주민의 도시지역과 농촌지역에서의 지역경제 발달에 대한 기여도의 차이는 농촌지역에서의 결혼이주 여성의 활동영역이 도시지역에 비해 더욱 건전하며, 그들의 남편의 사회경제적 능력 또한 도시지역에 비해 농촌지역이 더 건실하기 때문인 것으로 추정할 수 있다.

Tourist map design에 있어서의 픽토그램(Pictogram)에 관한 연구

유광 建國大學校 大學院 2002 국내석사

현대 사회에서 정보전달의 개념은 급속도로 변해가는 시대상의 과정으로 볼 때 매우 중요하다. 이렇듯 하루가 다르게 변해가는 시대에서 언어의 차이로 인한 국제교류의 장벽은 시급히 해결되어야 할 문제로 남아있다. 또한 각 분야의 개념이 확장되고 추상화됨에 따라, 문화와 역사가 서로 다른 나라는 물론, 서로 같은 민족끼리의 상호 커뮤니케이션 역시 점점 힘들어지고 있는 상황이다. 그것은 인간이 만들어 내는 역사적·문화적 환경속에서 경험이 고정된 것이 아니라 변하기 때문이다. 또한 그 변화된 경험을 지각하는 것보다 경험하려는 시간이 더 빠르게 지나가고 있기에 인지면에서 그 만큼 늦어질 수밖에 없는 것이다. 시각디자인중의 하나인 픽토그램은 문자와 말이 지닌 한계를 극복하는 국제적 시각언어로서 교류의 장벽을 허무는데 커다란 역할을 하고 있다. 그러므로 국내·외간의 커뮤니케이션을 용이하게 하고 경제적 혹은 시각적으로 전달기능을 강화하고 있는 픽토그램은 그 사용범위가 날로 광범위해지는 이유가 바로 여기에 있는 것이다. 이러한 폭 넓은 범위속에서의 픽토그램은 관광산업의 급속한 발달로 인한 자국의 관광지에 대한 효과적인 정보를 시각적으로 전달할 수 있는 관광지도에서도 볼 수 있다. 낯선 도시를 방문했을 때 그 도시 전체를 한눈에 일목 요연하게 알아볼 수 있도록 도와주는 관광지도야말로 그곳의 문화를 알려주는 그래픽 심볼인 것이다. 지도는 그 나라의 얼굴이자 사람이 직접 볼 수 없는 어떤 장소에 대한 정보를 자세히 알려주는 그래픽 커뮤니케이션의 수단으로서 디자이너의 표현기법에 따라 정보 전달의 효과가 달라진다. 현채 우리나라에서 제작되고 있는 관장지도는 국가 기본도를 기준으로 하여 제작되고 있기 때문에 그래픽 디자인의 개념으로 이해하기 어려울 정도로 미적인 그래픽 요소는 거의 배제되어 있다고 생각해도 좋을 것이다. 다시말해 GIS(지리정보시스템)에 최해 지도를 제작하기 때문에 효과적인 그래픽 요소에 대한 미적 특성은 전혀 고려되지 않고 했다. 관장지도는 그 기능상 일반지도와는 달리 이러한 그래픽요소들이 미적으로 표현되고 또한 보기 쉽게 단일화된 픽토그램이 구성되지 않으면 외국 및 자국 관광객에게 매력적이고 시각적으로 즐거움을 주는 관광지도가 될 수 없다. 이러한 상황에서 본 논문은 다음과 같은 취지를 두고 연구하고자 한다. 1) 관광지도用 픽토그램을 개발함으로서 생기는 통일성추구 2) 누구나 이해할 수 있는 자국적 픽토그램 개발 위 두가지의 목적을 가해고 최종적인 활용방안(관광치도)을 제시함으로서 픽토그램이 가지고 있는 보편적 통일성과 Visual Communication측면에서 그동안 보조수단으로만 인식했던 픽토그램이 하나의 학문적분야로 발전할 수 있음을 보여주고자 한다. It is very important to give information in current society on the faces of the times when change rapidly. So, language barrier in international relations is settled without a moment's delay with the change of the times. According as concept of every division is extended and abstracted, mutual communication in our country as well as different country in culture and history is hard gradually. This is because experience in historic and cultural environment by humans is not permanent but is changed. And because experience more than perception of changed experience is passed rapidly, it is lated as much in human knowledge. Pictogram of visual design is international visual language overpassing the limits of letter and speech. Therefore, it plays an important part in breaking up of international barrier. The reson why pictogram being plained international communication and consolidating economical, visual communication is just here. Pictogram can show in tourist map of sights which can communicate effective information in mother country visually within wide ranging the limits. Tourist map looking out at first sight clearly when we visits strange town is graphic symbol showing the culture, The map is honour of the country and a means of graphic communication informing of anything places that can not see directly. Such map become different effect of information. Because various maps made in the present our country is fixed on the basis of basic map of country, graphic elements are removed almost in graphic design. That is to say, because the map is made by GIS , esthetic sense of effective graphic elements is not considerated. Tourist map make difference general map. And it can be showed attraction and visual pleasure if graphic elements were not expressed and pictogram is not symbolized. Therefore this paper may be studied in purpose a s follows: ⅰ) Pursuit of unity due to development of pictogram in tourist map ⅱ) Development of pictogram can be understood everyone in mother country As mention purpose above and present the final plan(Tourist Map), development of pictogram in mother country should be showed in tourist map on the faces general unity of pictogram and visual communication.
