  • This study investigated the crude protein and amino acid contents of local agricultural products widely and specifically grown in Korea, including 25 vegetables and 13 fruits. The crude protein content of vegetables and fruits ranged from 0.46 to 6.53% and 0.29 to 2.23%, respectively. Totally, 17 types of amino acids were found in most samples. The total amino acid content of vegetables and fruits ranged from 457.38 to 9,303.18 mg% and 368.82 to 3,118.75 mg%, respectively. The total amino acid contents of garlic and passion fruit was higher compared to other vagetables and fruits. The calibration curves of the standard components showed good linearity ($r^2$>0.99), except Met ($r^2=0.989$). The limits of LOD and LOQ were in the range 0.034 to $0.991{\mu}g/mL$ and 0.009 to $0.474{\mu}g/mL$, respectively. The results of the study can serve as a fundamental source of information regarding crude protein and amino acids contents in food, for diet planning.

  • A total of 51 vegetables and fruits, commonly consumed agriculture products in Korea, were analyzed for their α-carotene, β-carotene, and β-cryptoxanthin contents as provitamin A. The beta-carotene content (㎍/100 g) was high in a few green leaf vegetables such as coriander (5,924.07), gegeol radish leaf (5.855.72), and curried mallow (5,138.01), while α-carotene and β-cryptoxanthin contents were not detected. The β-carotene in 8 kinds of 20 general vegetables was detected in the range of 214.06~1,437.67 ㎍/100 g, while α-carotene was detected at 460.17 ㎍/100 g in only old pumpkin. The β-cryptoxanthin was detected in the range of 106.55~315.49 ㎍/100 g in Japanese elm, watermelon, white cucumber, and lettuce. However, carotenoids were not detected in 10 kinds of agricultural products including oriental melon, potato, etc. In fruits, the beta-carotene contents ranged from 165.72~3,997.39 ㎍/100 g, showing maximum value in apple mango and minimum value in persimmon. The β-cryptoxanthin was detected at 232.22 ㎍/100 g in only passion fruit, while the α-carotene was detected at 77.25 ㎍/100 g in only darae. Thus, based on the analyzed results of carotenoids of agriculture products consumed or cultivated in Korea, and it was found that green leaf vegetables comprise high beta-carotene overall.

  • 지구온난화에 따른 기후변화로 과거에는 재배되지 않았던 아열대 작물의 국내재배가 확대되고 있다. 백향과(Passiflora edulis Sims)는 브라질 남부지역이 원산지인 아열대작물로 국내에서도 전국적으로 재배가 되고 있어서, 국내 재배현황과 재배농가의 관리기술 실태를 조사하여 재배 애로사항 및 발전과제를 도출코져 하였다. 백향과의 국내 재배는 2010년부터 시작되어 2017년에는 201농가 54.7ha로 정점을 이루고, 점차 감소하여 2019년에는 156농가 36.5ha에서 재배되고 있다. 재배농가가 많았던 지역은 남원, 담양, 화순, 김천, 고창 등 이었다. 백향과의 재배체계는 대부분의 농가가 비닐하우스 시설에서 겨울철 난방에 의한 다년 재배로 1년 2회 수확하고 있으며, 극히 일부농가는 1년 재배체계로 매년 묘목을 다시 심는 형태이다. 백향과의 국내 육성품종은 없으며, 외국에서 도입한 자색종 또는 교잡종을 주로 재배하고 있다. 현재 국립종자원에 '일반종', '타이농1하오', '황금' 3품종이 생산/수입 판매 신고되어 있다. 초기에 도입한 접목묘를 재배하면서 국내에서 삽목묘를 육성하여 많은 농가가 재배하고 있다. 백향과는 덩굴성이기 때문에 지주를 설치하여 재배하는데 재식거리, 수형, 가지유인 등을 농가별로 다양한 방법으로 하고 있는 실정이다. 개화기에 인공수분 작업이 필요하고, 수확은 과일이 성숙하여 저절로 낙과하면 주어서 수확한 과일은 주로 생과로 판매하는데 전화 및 인터넷 주문에 의한 직거래가 가장 많고, 일부 마트 및 로컬푸드에 판매하고 있다. 국내재배 안전성 향상을 위하여 필요시 되는 기술개발 과제는 적응 품종육성 및 무병묘 생산 보급, 고품질 백향과 생산을 위한 재배관리 기술, 시설재배 환경관리 기술, 소비 증대를 위한 가공 이용 기술 개발 등으로 전문기관에서의 연구개발이 필요하다.

  • Contents of water soluble vitamin $B_6$ in a total of 62 agricultural products cultivated in local areas in Korea were analyzed by high performance liquid chromatography with fluorescence detector (HPLC/FLD). To verify the method of vitamin $B_6$ analysis, a quality control chart was formulated with in-house control using a mixture of broccoli and shiitake mushrooms. Among cereals, high content of vitamin $B_6$ measured $234.3{\sim}260.3{\mu}g/100g$ in dried mung bean and soybean. Vitamin $B_6$ content of non-glutinous and glutinous black rice measured $105.0{\mu}g/100g$ and $129.7{\mu}g/100g$, respectively. In vegetables, high content of vitamin $B_6$ were measured in passion fruit ($104.3{\mu}g/100g$), gat ($55.7{\sim}84.3{\mu}g/100g$), gomchwi ($31.3{\sim}88.0{\mu}g/100g$) and garlic ($72.7{\sim}98.3{\mu}g/100g$). Among fruits, gold kiwi 'Zespri' and green kiwi 'Hayward' revealed high vitamin $B_6$ content of $116.3{\mu}g/100g$ and $78.7{\mu}g/100g$, respectively. In persimmons, daebongsi had high vitamin $B_6$ content ($36.0{\sim}72.7{\mu}g/100g$) than bansi and sweet persimmon. Vitamin $B_6$ content in dried jujube and persimmon increased more than $86.7{\mu}g/100g$ compared to fresh materials. Among specialty crops, green tea powder ($64.7{\sim}251.0{\mu}g/100g$) and sansuyu ($172.3{\mu}g/100g$) revealed high content. Of mushrooms, vitamin $B_6$ content of Sparassis crispa ($139.3{\mu}g/100g$) was the highest. Vitamin $B_6$ content information of agricultural products in local areas in Korea collected from this experiment will be used as valuable preliminary data for grasp national nutritional status.

  • Lake Biwa Canal was a dream project that reminds us the passion and innovation of Kyoto Citizens more than water supply. It is a modernization project combining engineering knowledge and scientific technology, which started transportation by ship through big-scale civil construction as well as supplying electricity as the first waterpower plant in Japan, and it overcame the physiographic limit through adopting unique method of waterway transportation. Lake Biwa Canal, which has tangible and intangible culture heritage value as the traditional space of Kyoto, the Old Capital of 1200 years, conceives a cultural meaning that is connected through various mutual relation as well as scientific technologic factor. Lake Biwa Canal is not only the function for supplying water to gardens and temples of Kyoto region, but it is also a cultural fruit that is formed by complex causal relationship of various contents such as geographical and environmental background, the phases of the times, local development policy, political circumstances and religions. This study is aimed at interpreting the value of Lake Biwa Canal multilaterally by the convergence of cultural and technological aspects through the view of the world which the age tried to pursue, focusing on the construction of Lake Biwa Canal which was accomplished in the process of promoting the modernization of Kyoto.

  • This article started with 'encounter'. Both authors met around the middle of February and discussed the subject for the inhospital conference presentation scheduled at the break of June. Having conversation like "Movies similar to fairytales heard from childhood are standing out conspicuously among commercial films which are attracting audiences and receiving fervent response these days. This phenomenon is marvelous and mysterious." together, and sharing this and that, the conversation turned naturally to 'Bram Stoker's Dracula', 'Series of Twilight', and 'Warm Bodies', both authors found out the fact that we saw these movies in common with propound impression. Feeling our hearts beating high, bit of fear and hesitation followed simultaneously at the moment when both of us encountered the idea to choose subject of conference presentation related to this and expressed one in words. While preparing for the conference, presenting to others, and having discussion with the audience, our hearts have been filled with Presentation was finished after active discussion beyond fixed hour and it also brought audience (among those present) to show strong emotional response both positively and negatively. At first, we just had a thought to put aside the content of presentation, but we felt lack of something else, lingering in our minds. We finally decided to accomplish our work into an article leading to submission, based on the advice and recommendation from one of the audience. This article is a small 'creative writing' born by sharing both authors' passion and enthusiasm. In the first part of this article, we have introduced the dream of 31-year-old woman's which led to the 'creative writing' and spotlighted her personal life, before and after the dream. In the second part, we have examined the consequence (way of realization) and meaning of creative impulse shown from or experienced from personal unconsciousness (dream, fantasy) together. Creative impulse shown from the individual appeared to bring creative transformation of individual personality through the process of 'introversion'. Otherwise it also appeared to be delivered as a masterpiece through 'creative writing' or from the process of 'extroversion'. Sometimes both consequences happened at once. We tried to examine and interpret the dream of 31-year-old woman's, which was introduced in the first part of this article, that is to say, the dream of 'Stephenie Meyer's, the author of the 'love between vampire boy and ordinary human girl' themed novel 'Twilight Series', in a psychoanalytic perspective. In the third part, highlighting individual dreams and three different movies 'Bram Stoker's Dracula', 'Twilight Series', and 'Warm Bodies', we found the transformation of symbol 'Man of Darkness, vampire' seen in each individual dreams and in some specific popular arts, such as novels and movies, receiving fervent response from people. We also found love between this symbol and humane woman, bearing fruit together with very impressive change shown in the attitude of 'Man of Darkness' (vampire)'s conscious ego and mutual relationship pattern. We contemplated this phenomenon, the reason why these events happen, and what kind of association presents among these events, individual, and this era and discussed the effects on individuals and this era, at present. 'Creative impulse', originated in the deep structure of human mind is realized as a 'transformation of individual personality' or masterpiece through artistic creation. If it has a chance to make a match with this era, shared by a lot of contemporary people, it also appears to bring positive effect as healing and salvation to each individual or to each era. From this article, we mainly highlighted positive and healing aspects of individual 'creative impulse'. We hope to deal with the negative consequences and their reason coming from 'creative impulse', if the occasion arises, in the future with a new article.
