  • 본 연구는 우리 나라의 여러 가지 산채류 중에서 참취(학명: Aster scaber)를 이용한 스낵제품의 참취와 기름의 첨가 수준에 따른 이화학적 및 관능적 특성을 조사하여 최적수준을 알아본 것으로 요약하여 보면 다음과 같다. 참취와 기름의 첨가량에 따른 스낵의 이화학적 특성을 조사한 결과 L값(명도)은 참취의 첨가량이 증가할수록 낮아졌고, 기름의 첨가량이 증가할수록 높았다. 갈변도는 참취의 첨가량과 기름 첨가량이 증가할수록 감소하였다. 기름 흡수율은 참취의 첨가량이 증가할수록 크게 감소하였다. 팽화율은 참취의 첨가량이 증가할수록 감소하고 기름의 첨가량이 증가할수록 증가하였다. Texture analyzer로 측정한 스낵의 경도는 참취의 첨가량이 증가할수록 증가하고 기름첨가량이 증가할수록 감소하였다. 참취와 기름의 첨가량에 따른 스낵의 관능적 특성을 조사한 결과 어두운 정도와 참취향은 참취첨가량이 증가할수록 증가하였고, 기름첨가량이 증가할수록 약간 감소하였다. 경도는 참취첨가량이 증가할수록 증가하고 기름첨가량이 증가할수록 감소하였다. 바삭바삭한 정도는 참취첨가량이 증가할수록 감소하고 기름첨가량이 증가할수록 증가하여 경도와 반대 경향을 보였다. 기름진 정도는 참취가 증가할수록 감소하고 기름이 증가할수록 증가하였으며, 짠맛은 참취첨가량이 증가할수록 증가하였고, 기름첨가량이 증가할수록 감소하였다. 참취 스낵을 제조하기 위한 요인들의 최적 수준은 바람직한 특성인 바삭바삭한 정도가 5점 이상이고, 바람직하지 않은 특성인 기름진 정도가 5점 이하일 때 경제성을 고려하여 팽화율이 최대가 되는 처리 조합을 최적수준으로 결정하였다. 그 결과 최적 수준은 참취 8.6%첨가, 기름 7.6%첨가로 결정되었다. 본 연구 결과로 개발된 참취 스낵을 1일 약 70개(90g) 섭취할 경우 한국인 1일 영양권장량에서 권장하는 총 식이섬유량 20g의 1/2을 만족시키고 우리 나라 국민에게 가장 섭취량이 낮은(67%) Vitamin A의 권장량인 700 R.E.중 139 R.E.를 공급할 수 있으며, flavonoids 1.2mg도 공급할 수 있다. 따라서 참취 스낵의 이용은 노약자와 어린이 등의 섬유소를 쉽게 섭취할 수 없는 계층의 사람들이 쉽게 섭취할 수 있어 건강증진에 크게 도움이 될 것이며, 참취의 계절적 제약 및 저장기간이 짧은 단점도 보완할 수 있어 새로운 신토불이(身土不二) 식품개발로 인한 농가소득도 기대할 수 있을 것으로 생각된다.

  • 서로 다른 한국 전통 견직물의 촉감에 대한 주관적 감각의 한$\cdot$미 양국의 차이를 고찰하고 전통 견직물의 주관적 촉감에 영향을 미치는 역학적 성질을 규명하고자, 한국인과 미국인 각 20명을 대상으로 의미분별척도에 의하여 서로 다른 6개의 한국 전통 견직물의 촉감(딱딱함, 매끄러움, 성김, 시원함, 유연함, 까실거림, 무게, 두께)을 평가하였다. '매끄러움'과 '성금', '까실거림', '두꺼움'은 한$\cdot$미 양국인의 평가가 유사한 경향을 나타내어, 공단과 뉴똥은 매끄럽고 치밀하며 흐믈거리고 두껍다고 평가받은 반면, 갑사와 숙고사, 항라는 거칠고 성글며 까실 거리고 얇다고 평가되었다. '시원함'과 '유연함'에 대해서는 한$\cdot$미 양국인의 주관적 평가에 차이가 있어 '시원함'의 평가에서 한국인의 점수는 미국인에 비하여 직물별로 큰 차이를 나타내어 한국인은 전통 견직물 촉감의 '시원함'에 보다 민감한 것으로 나타났으며, '유연함'에 대해서는 한국인보다 미국인이 공단과 갑사, 숙고사의 촉감을 더 유연한 것으로 평가하였다. 견직물의 주관적 촉감을 예측하는 회귀식에서 한국인의 촉감은 표면특성과 굽힘 특성에 의해, 미국인의 촉감은 표면특성과 인장특성, 압축특성에 의해 주로 예측되었는데, 특히 미국인의 '시원함'은 압축회복성에 의해, '유연함'은 인장 회복성에 의해 예측되는 것으로 나타나, 미국시장을 위한 전통 견직물의 감성적 설계에 활용할 수 있을 것으로 기대된다.

  • Synthetic fabrics, such as nylon and polyester, were dyed with persimmon juice by using a padding mangle repeatedly. The mechanical properties of these synthetic fabrics were analyzed using the Kawabata evaluation system. The following findings were obtained from this investigation. As the number of repetitions of padding dyeing increased, the tensile energy per unit area and the tensile resilience of synthetic fabric remained almost unchanged, whereas the linearity of the load-extension curve of the synthetic fabrics increased. As the number of padding repetitions increased, the synthetic fabrics dyed with persimmon juice exhibited increases in thickness and weight. As the number of repetitions of padding treatment with persimmon juice increased, the values of stiffness, anti-drape stiffness, fullness, and softness also increased, whereas the flexibility with soft feeling, crispness, and scrooping sensation significantly decreased. The amount of coated persimmon juice on the surface of the fabrics increased after three repetitions of padding treatment with persimmon juice. Nylon and polyester fabrics were dyed evenly with persimmon juice treated using a padding mangle.

  • This study investigates the kimchi from Jangsu area (JSK) and its comparison with commercial kimchi (CMK). We conducted a sensory evaluation for the pH, titratable acidity, salinity, hunter's color values and mechanical characteristics of kimchi. The pH of JSK is significantly higher than CMK throughout the fermentation (p<0.001). At 15 days, JSK reached the stage of optimal maturity for pH 4.23~4.55 and CMK showed pH 3.96~4.00 as conditions after the optimal maturity (p<0.001). From the results of acidity analyses, CMK also showed higher acidity values than JSK (p<0.001), indicating that the rate of fermentation progress was faster in CMK. Salinity of JSK was a litter higher than CMK1 and CMK2 (p<0.001) and JSK indicated significantly higher L, a, b values during fermentation (p<0.001). Moreover, the textural values were significantly higher in JSK2 and JSK3 retaining hardness of the tissues. In the sensory assessment, the color, flavor, crispness, taste, and overall preferences were higher in JSK3 at 15 days and 30 days than CMK. Therefore, it seems necessary for recipe developments of kimchi with local characteristics in order to industrialize kimchi by using alpine crops at Jangsu area.

  • In this study, a change of hand of fabrics dyed with persimmon juice was measured using Kawabata Evaluation System. Using various cotton fabrics, linen fabric and silk fabric used frequently for persimmon juice dyeing, we examined the changes of physical properties and hand according to persimmon juice dyeing and washing. The dynamic characteristics of hand were measured tensile, shear, bending, compression, surface properties, thickness and weight. Linearity of load-extention and tensile resilience were increased in all kinds of fabrics after dyeing. Tensile energy decreased in cotton fabric 2(gauze), cotton fabric 3(muslin) and linen fabric. Shear stiffness and hysteresis of shear increased in most of fabrics. Bending rigidity of the bending property and hysteresis of bending, linearity of compression of the compression property, compression energy and compression resilience increased in all kinds of fabrics after dyeing. Thickness and weight increased much in all kinds of fabrics after dyeing. In the primary hand value, stiffness and anti-drape stiffness increased in all kind of fabrics after dyeing. The fullness and softness, crispness, scrooping feeling and flexibility with soft feeling decreased. As the stiffness after persimmons dyeing increased, it was suitable for clothes material of summer.

  • The effects of the water extracts from thyme(TM) and tarragon(TG) on shelf-life and quality of kimchi were investigated by measuring the changes in pH, acidity, number of total microorganisms, number of Lactobacillii and Leuconostoc during fermentation at 1$0^{\circ}C$, and were tested for antimicrobial activities against Lactobacillus plantarum and Leuconostoc mesenteroides. TM and TG were extracted with water, ethyl ether, ethyl acetate and ethanol. Water, ethyl ether, ethyl acetate and ethanol extracts of TM showed antimicrobial activities against Lactobacillus plantarum and did not observed against Leuconostoc mesenteroides. On the other hand, water, ethyl acetate and ethanol extracts of TG showed antimicrobial activities against Leuconostoc mesenteroides and did not observed against Lactobacillus plantarum. The decrease of pH and the increase of acidity showed lower in kimchi prepared by adding water extracts from TM than in products from TG. The number of total microorganisms were also detected less in the kimchi prepared by adding water extracts from TM. And, the properties of barkless of kimchi measured instrumentally were higher for kimchi prepared by adding water extracts from TM, also maintaining good crispness. The optimal addition amounts of both TM and TG for good overall and spicy taste of kimchi were 0.03%. The results suggested the possible use of the extracts of TM and TG can be successfully used for the quality and extension of shelf-life of kimchi.

  • This study was investigated to find effects of soaking-water salt concentration and submaterial on Kimchi taste and fermentation period. several parameters such as pH, acidity, reducing sugar, amino acid and sensory evaluation during fermentation at 2$0^{\circ}C$ were experimented. The results are as follows : As fermentation period increases, pH and content of reducing sugar of Kimchi have decreased. But acidity has increased. Especially, the pH of all samples rapidly decreased to a extent of pH 4.2. During fermentation the acidity and content of reducing sugar in 12% soaking-water were higher than those in 16% and 20%. Content of reducing sugar I Kimchi was observed to play an important role for the overall taste. As a result of sensory evaluation during fermentation, Kimchi in 16%, 2.6% and in 20%, 3.7%. Sensory evaluation revealed that leek-added Kimchi was highly evaluated in crispness, sour taste, flavor and overall acceptability. These results suggested that Kimchi fermented for 4days at 2$0^{\circ}C$ with 16% salt concentration of soaking water and leek as submaterials should taste most desirable.

  • In order to investigate the relationship between subjective sensation for fabric sound and touch and the objective measurements, eight different apparel fabrics were selected as specimens. Sound parameters of fabrics including level pressure of total sound (LPT), level range (ΔL), and frequency differences (Δf) and mechanical properties by Kawabata Evaluation System (KES) were obtained. For subjective evaluation, seven aspects of the sound (softness, loudness, pleasantness, sharpness, clearness, roughness, and highness) and eight of the tough (hardness, smoothness, fineness, coolness, pliability, crispness, heaviness, and thickness) were rated using semantic differential scale. Polyester ultrasuede was evaluated to sound softer and more pleasant while polyester taffeta to sound louder and rougher than any other fabrics. Wool fabric such as worsted and woolen showed similar sensation for sound but differed in some touch sensation in that woolen was coarseast, heaviest, and thickest in touch. In the prediction model for sound sensation, LPT affected positively subjective roughness and highness as well as loudness, while ΔL was found as a parameter related positively with softness and pleasantness. Touch sensation was explained by some of mechanical properties such as surface, compressional, shear, and bending properties implying that a touch sensation could be expressed by a variety of properties.
