The objectives of this study were to analyze the design elements of hairstyles, wedding headdresses, and necklines in wedding magazine pictures by using content analysis method and to investigate the differences in image perception according to hairstyle, wedding headdress, and neckline. A quasi-experimental method by questionnaire was used. The experimental design was a $2{\times}5{\times}4$(hairstyles${\times}$wedding headdresses${\times}$necklines) factorial design by 3 independent variables. The subjects consisted of 378 female college students. The results are as follow. First, the most popular among hairstyles, headdresses, and neckline forms were the updo hairstyle, dark brown hair color, the crown headdress, white flowers, and the horizontal bared top. Second, the elements determined to be most elegant and attractive were the medium-up hairstyle and the crown with a veil. However the wedding hat was perceived to be high in individuality and tenderness, while the flower and the wedding hat were perceived to be very pretty. The halter neckline was perceived to be higher in individuality and attractiveness than the other neckline types. Third, the medium-up hairstyle when wearing a crown with veil was perceived to be the most elegant. Placing a flower in the long-wave hairstyle was evaluated as looking most pretty. Fourth, the medium-up hairstyle was higher in preference than the long-wave style. Among wedding headdresses, there was greatest preference for a crown.

The purpose of this study is to compare the purchase intention on naturally dyed clothing between Korea and the US. As independent variables that affect the purchase intention, benefits that consumers seek when purchasing naturally dyed clothing, especially for fabric materials, and attitudes towards naturally dyed clothing were selected. A quantitative research method with a survey was employed. 160 data from Korea and 180 data from the US were used for the analysis. The convenience sampling method (i.e., college female students) was used. Descriptive statistics, factor analysis, t-test and regression analysis were employed to test the differences in purchase intention, fabric benefit sought, and the attitudes. The fabric benefit sought selected for this study includes eco-friendliness, uniqueness, aesthetic, comfort and quality. The attitude toward naturally dyed clothing was categorized as an emotional and a cognitive attitude. The results show the significant differences in the fabric benefit sought depending on nationality, major and experiences in natural dyeing. Significant differences were found in of the attitude toward naturally dyed clothing among the nationalities and the experience types in natural dyeing. In addition, there were significant differences in purchase intention toward naturally dyed clothing between Korean and the US participants, and countries show different fabric benefits and attitudes which influenced participants' purchase intention. The results of this study suggest an appropriate fabric planning for environment-friendly fashion products for both countries.

The beneficial effects of lactic acid bacteria (LAB) have been intensively investigated in recent decades with special focus on modulation of the host intestinal microbiota. Numerous discoveries of effective probiotics are driven by a significantly increasing demand for dietary supplements. Consequently, technological advances in the large-scale production and lyophilization are needed by probiotic-related industries for producing probiotic LAB for commercial use. Our study had a dual objective, to determine the optimum growth medium composition and to investigate appropriate cryoprotective additives (CPAs) for Lactobacillus salivarius, and compare its responses with other Lactobacillus species. The one-factor-at-a-time method and central composite design were applied to determine the optimal medium composition for L. salivarius cultivation. The following composition of the medium was established (per liter): 21.64 g maltose, 85 g yeast extract, 1.21 ml Tween 80, 6 g sodium acetate, $0.2g\;MgSO_4{\cdot}7H_2O$, $0.02g\;MnSO_4{\cdot}H_2O$, $1g\;K_2HPO_4$, $1.5g\;KH_2PO_4$, $0.01g\;FeSO_4{\cdot}7H_2O$, and 1 g sodium citrate. A cryoprotective additive combination comprising 10% (w/v) skim milk and 10% (w/v) sucrose supplemented with 2.5% (w/v) sodium glutamate was selected for L. salivarius, and its effectiveness was confirmed using culture-independent methods in the freeze-dried cells of the Lactobacillus strains. In conclusion, the optimized medium enhanced the species-specific cultivation of L. salivarius. On the other hand, the cryoprotective effects of the selected CPA mixture may also be dependent on the bacterial strain. This study highlights the necessity for precise and advanced processing techniques for large-scale production of probiotics in the food and feed industries.

Purpose: This paper is a basic study done to establish a theory of health according to Korean culture. The focus is on identifying perceived concepts of health in older Korean women. Method: The Q-method, which is effective in measuring individual subjectivity, was used in this study. Results: Perception of the concept of health was found to have 4 independent types, as follows. 1. Type I : natural & couple-oriented type. Women with this type not only have a naturalistic view of health but also put weight on being couple-centered. 2. Type II: oriental & children-oriented type. These women have traditional oriental views of the world, and are strongly dependent on their children. 3. Type III: western & altruistic type. These women do not agree with oriental concepts of health. They are positive altruists, pursuing the meaning of life. 4. Type IV: modern & self-oriented type. Women with this type not only interpret the concepts of health within western medicine, but also positively accept oriental views of the world. Conclusions: Health concepts of older Korean women are complicated, not only with western-medical concepts of health, but also more strongly complicated with concepts from oriental medicine.

Vertically-aligned silicon nanostructure arrays (SNAs) have been drawing much attention due to their useful electrical properties, large surface area, and quantum confinement effect. SNAs are typically fabricated by chemical vapor deposition, reactive ion etching, or wet chemical etching. Recently, metal-assisted chemical etching process, which is relatively simple and cost-effective, in combination with nanosphere lithography was recently demonstrated for vertical SNA fabrication with controlled SNA diameters, lengths, and densities. However, this method exhibits limitations in terms of large-area preparation of unperiodic nanostructures and SNA geometry tuning independent of inter-structure separation. In this work, we introduced the layerby- layer deposition of polyelectrolytes for holding uniformly dispersed polystyrene beads as mask and demonstrated the fabrication of well-dispersed vertical SNAs with controlled geometric parameters on large substrates. Additionally, we present a new means of building in vitro neuronal networks using vertical nanowire arrays. Primary culture of rat hippocampal neurons were deposited on the bare and conducting polymer-coated SNAs and maintained for several weeks while their viability remains for several weeks. Combined with the recently-developed transfection method via nanowire internalization, the patterned vertical nanostructures will contribute to understanding how synaptic connectivity and site-specific perturbation will affect global neuronal network function in an extant in vitro neuronal circuit.

본 연구는 간호 대학생들을 대상으로 취업에 대한 생각 구조를 분석하고자 20세에서 30세 사이의 대학생 10명을 대상으로 총 5회에 걸친 인터뷰를 실시하였다. Giorgi 방법을 이용하여 분석한 결과 간호 대학생들의 취업에 대한 생각 구조는 3개의 범주로 나누었으며, 구성요소는 14개이었다. 3개의 범주는 1. 취업의 영향력, 2. 실무교육의 필요성, 3. 힘들지만 참고 견딤으로 나타났으며, 구성요소는 "보다 나은 삶" "미래" "생계유지" "가정 형성" "새로운 시작" "독립" "밀접한 관계" "깊이 있는 학습은 스스로 해야 함" "수업과 취업은 긴밀한 연관" "통합적 학습 매뉴얼이 필요함" "취업 경쟁이 덜함" "수요가 많고 다양한 분야" "과정이 까다롭고 국가고시에 대한 압박감" "한 단계 더 나은 인생이 펼쳐질 것"이었다. 결론적으로, 간호 대학생들은 취업은 인생의 새로운 시작이며, 독립을 의미하고 있었으며, 간호학과는 다른 과에 비해 취업분야가 보장된다고 생각하고 있었으나 과정이 힘들게 느끼고 있었으며, 학교 수업이 취업에 매우 밀접한 관련이 있는 만큼 실질적이고 통합적 매뉴얼의 개발을 필요로 하다고 느끼고 있었다. 이에 따라 본 연구를 통하여 간호과 학생들의 효과적인 취업을 위해서는 학생들 수준에 맞는 교육과정 연구와 타당하고 실질적인 이론 실습 매뉴얼을 개발할 것을 제안한다.
