  • Purpose: The objective of this study is to evaluate the effect of cultivation conditions on the growth and glucosinolate content of Chinese cabbage and kale. Methods: Chinese cabbage and kale were grown in three different cultivation conditions, including a plant factory, greenhouse, and open field. Samples were collected at two harvesting times (10 d and 20 d after transplanting the seedlings). Nine growth parameters (plant height, plant width, number of leaves, petiole diameter, SPAD readout, leaf length, leaf width, stem diameter, and plant weight) were measured immediately after harvesting, and the samples were freeze-dried and stored until the glucosinolate content was analyzed. Mean values of the growth parameters and glucosinolate contents were evaluated using Duncan's multiple range tests. Results: The results indicated that the plant parameters of the Chinese cabbage and kale were greater for plants grown in the plant factory and greenhouse. The plant height, width, and weight showed significant differences in the Duncan's multiple range tests at a 5% level. The plant factory also produced greater contents of most of the glucosinolates. Conclusions: Three different cultivation conditions significantly affected the growth and glucosinolate contents of Chinese cabbage and kale. Further study is necessary to investigate other functional components and different vegetable varieties.

  • 최근 한의학에서는 인체를 8가지 체질로 나누는 8체질의학에 대한 관심이 높아지고 있다. 그런데 8체질은 맥진에 근거하여 판별되므로, 8체질의 판별 및 병증의 치료를 표준화시키기 위해서는 객관적인 8체질의 특성을 찾아내어 이것을 표준화시키는 일이 절실하다. 본 연구에서는 맥진을 통하여 8체질로 분류된 후 8체질 침법에 따라 치료 중인 남자 환자들의 신체적 특징과 증후 등을 설문을 통하여 문진하였다. 그리고 일원배치 분산분석법에서 유의한 문항들에 대하여 다중비교법을 이용하여 8체질 사이의 평균 차이를 표로 나타내었다. 이 분석에서 유의하게 나타난 문항들은 실제의 진단 및 치료에서 관찰되어온 8체질 특성과 잘 일치하고 있었다.

  • Recently, need for the development of the quantification of subjective evaluation is growing for the production of high-touch and high-tech textile products. In this study, Fuzzy theory is utilized for the evaluation of the wear comfort of the various blouses. Result of a new evaluation method and factor scores, validity of the new evalution technique adopted fuzzy theory was crosschecked with the results of fator analysis and factor scores. As results, fuzzy theory was proved to be adequate methodology to objectify the subjective evaluation of the adequacy of clothing which is worn. When DUNCAN'S multiple comparion among median of the fuzzy composite score were compared with the results of factor score, the sensitivity of the test methods tends to increase. Therefore, it is suggested that fuzzy weighted checklist is an alternative evaluation scale for the subjective comparison of the textile products. In addition, individual median of fuzzy composite score value should be treated by statistical for the sensitive analysis of subjective evalution.
