漢字構形學은 한자를 구성하는 단위의 개념을 규정하고 각 단위가 맺는 공시 적, 통시적 관계를 밝혀내어 관계를 지배하는 원리를 기술하는 학문이다. 1980년대 말에 한자구형학 이론이 정립된 후 2002년에 처음 출판된 󰡔漢字構形學講座󰡕부터 10여 년이 지난 후 2015년에 출판된 󰡔漢字構形學導論󰡕까지 내용이 보완되면서 점차 늘어난 편폭 만큼 한자구형학에 대한 저자의 깊은 통찰력도 더욱 분명하게 드러난다. 이 책 서문에서 저자는 한자를 인식하는 데 필요한 두 가지 열쇠가 표의성(表意性)과 형태 구성(構形)의 체계성이라고 강조하고 있으며, 이것은 漢字構形學을 지배하는 기본 원리라고 할 수 있 다. 漢字構形學은 한자의 본체인 ‘형태(形)’에 초점을 맞추어 한자의 형태가 구성되고 변화하는 과정에서 나타나는 ‘현상’을 연구하며, 그 이론을 관통하고 있는 핵심 주제는 한자의 ‘체계성’이다. 체계성의 핵심 의미는 그 체계를 구성하는 요소 간의 유기적 관계 에 있다. 이 책은 한자의 본체인 자형(字形)을 중심으로 한자 체계의 내부적, 외부적 요 소 간의 ‘관계’를 폭넓게 다루고 있다. 그리고 한자 체계 내부에 존재하는 각종 관계와 외 부 요소와의 관계는 통시적인 형태 변화 과정에서 나타나는 현상을 근거로 증명한다. 이 책은 이론적인 문제의 해결에서 ‘관계’를 기술하여 설명하고 ‘근거’를 들어 ‘증명’하는 한 자학의 학술적 의미를 되새기게 한다.

목적 : 본 연구는 국민건강영양조사 제8기(2019-2021) 원시자료를 이용하여, 생체지표를 통한 휘발성 실내환 경요인(휘발성 유기 화합물, VOCs)과 백내장의 연관성을 파악하고자 하였다. 방법 : 백내장 의사진단 여부 및 가정 실내공기질 측정에 참여한 만 40세 이상의 성인 총 1,150명을 대상으로 하였다. 일반적 특성에 따른 휘발성 실내환경요인의 농도와 백내장의 유 ‧무에 따른 휘발성 실내환경요인의 농도를 비교하기 위해 복합표본 기술통계 분석과 로지스틱회귀분석을 하였다. p<0.050인 경우 유의한 것으로 판단하였다. 결과 : 대부분의 실내 휘발성 환경오염물질의 생체지표는 백내장을 진단받은 대상자에서 높게 나타났다. 특히 Benzene, Xylene, Acrolein, 1-Bromopropane, 1,3-Butadiene의 생체지표 평균농도(GM)가 백내장 진단받은 대상자들이 유의하게 높게 나타났다. 연령, 성별, 결혼, 알콜, 흡연, 소득을 보정한 복합표본 로지스틱회귀분석에 서, 1,3-Butadiene의 생체지표는 약 2배(OR 1.905(95% CI: 1.001, 3.625))의 위험도로 백내장에 영향을 미칠 수 있는 것으로 나타났다. 결론 : 본 연구는 기존에 밝혀지지 않은 휘발성 실내환경요인과 백내장의 연관성을 파악함으로써, 일부 휘발성 실내환경물질은 백내장의 원인물질로 작용할 수 있는 가능성을 보여주었다.

The aim of this study was to develop a body type suitable for adult men aged from their 20s to their 40s and to present a method of drafting related patterns. To this end, the somatic surface pattern data from previous studies were used. The research method involved drafting torso patterns for each type by setting and distributing the ease to the somatic surface pattern. Appearance evaluation was performed with virtual clothing. Then, the torso pattern for each body type was completed and presented as a draft method. SPSS was used for data analysis in this study. The research results are as follows. Types 1, 2, and 3 were set to 7%, 6%, 5%; 7%, 6%, 4%; and 6.5%, 7%, and 6% for chest, waist, and hip circumference measurements, respectively. The ratio of front to back was 50%:50%, 50%:50%, and 50%:50% of the spare for each body part for Type 1; 70%:30%, 50%:50%, and 60%:40% for Type 2, and 60%:40%, 70%:30%, and 60%:40% for Type 3. A tight-fit torso pattern for each body type suitable for adult males in their 20s to 40s was drafted, which was modified and supplemented through the evaluation of the first and second virtual wear. Considering the practicality of this approach, for generalization of the patterns, the items of the pattern were converted into a drafting method and presented as a draft method.

This study was designed to explore effective techniques to be used in IERW (Integrated English Reading and Writing) classes for college students. The study last for 15 weeks and included 457 students and 11 instructors at E University. The participants were freshmen who were taking a compulsory English reading and writing class, and the instructors were seven native English speakers and four Koreans. To ensure the effectiveness of IERW classes, it is important to identify what teaching activities are being used and which activities students prefer. To address these issues, the instructors were interviewed regarding their teaching activities in IERW classes. From the interview results, a survey was made that asked students which class activities they consider useful. The results show that most students responded positively to the activities that the instructors were using, with a preference of around 70 percent. Notably, pair or group activities were rated as less favorable than other activities, with a score of under 50 percent. Some implications of the findings and suggestions for teaching activities for IERW classes are provided.

This study is based on a representative body shape drawn from previous studies that classify adult male torso shapes. In this study, a design method is proposed by developing a tight-fit pattern that can be easily developed into various items and designs using the body surface development figure. This is obtained by converting the 3D body shape of the model representing the representative body shape. The specific design method was conducted as follows. Actual measurement values were used for waist back length, waist-to-hip length, shoulder length. The scye depth was determined as C/4–1.7 cm, and the front and back Interscye was set at (1/2 × actual measurements)–0.2 cm. The front-back neck breadth was set to (1/5 × base neck circumference)–1.3 cm and (1/5 × base neck circumference) cm. The front-back neck depth was set to (1/5 × base neck circumference)–1.2 cm and 3.5 cm. Front chest circumference was C/4–1 (front-back difference)cm; (1/4 × back chest circumference) was C/4 + 1 (front-back difference) + 0.3 (dart amount) cm. Front waist circumference was W/4–0.2 (front-back difference) + 2.2 (dart amount) cm; back waist circumference was W/4 + 0.2 (front-back difference) + 2.5 (dartamount) cm; front hip circumference was H/4 + 0.2 (ease) + 0.2 (front-back difference) cm; and back hip circumference was H/4 + 0.2 (ease)–0.2 (front-back difference) cm; Front droop was 1.6 cm. The newly developed tight-fit pattern is expected to be of great use as a basis for garment construction.

다수호기 부지에 위치한 원전의 해체는 인근에 위치한 운영중인 원전으로 인해 작업자에게 추가적인 방사선 피폭 위험을 야기할 수 있다. 따라서 인근의 운영중인 다수호기 원전에 의한 해체 작업자에 대한 피폭 선량 평가가 필요하다. ENDOS프로그램은 한국원자력연구원(KAERI)에서 개발된 선량평가 전산코드로, 하위 프로그램으로 대기 확산 평가 프로그램인 ENDOSATM과 기체 방사성 배출물에 의한 피폭 선량 계산을 수행하는 ENDOS-G가 있다. 이 프로그램들을 이용하여 고리 1호기 해 체작업자에 대한 다수호기 원전 운영에 의한 피폭 선량을 계산한 결과, 2.31×10-3 mSv·y-1로 일반인에 대한 피폭선량 기준치인 1 mSv·y-1에 비교해 보았을때 큰 영향이 없을 것이라는 판단에 도달할 수 있었다. 앞으로 예상되는 국내 해체 원전의 경우 모두 다수호기 부지에 위치하여 이 연구 방법과 결과가 활용될 수 있을 것이라고 기대한다.

This study optimized physicochemical factors for the sphericity of capsule type-fish roe analogs using equipment with double nozzles. The manufacturing process of fish roe analogs was optimized by response surface methodology with central composite design. For the optimum conditions of sphericity, sodium alginate concentration, calcium chloride concentration, agitation speed of calcium chloride solution in a reactor, and dropping height were investigated as independent variables. Soybean oil was put into the equipment through an internal nozzle, along with sodium alginate solution through an external nozzle into calcium chloride solution. The optimum conditions for the production of fish roe analogs were 1.66% (w/v) sodium alginate, 1.86% (w/v) calcium chloride, agitation speed of calcium chloride at 280 rpm, dropping height at 17 cm between the tip of the nozzle and the surface of calcium chloride solution. Consequently, the fish roe analogs showed a high sphericity of 99.8±0.77% at optimal conditions.

We have investigated the influence of system composition and preparation conditions on the particle size of vitamin E acetate (VE)-loaded nanoemulsions prepared by PIC(phase inversion composition) emulsification. This method relies on the formation of very fine oil droplets when water is added to oil/surfactant mixture. The oil-to-emulsion ratio content was kept constant (5 wt.%) while the surfactant-to-oil ratio (%SOR) was varied from 50 to 200 %. Oil phase composition (vitamin E to medium chain ester ratio, %VOR) had an effect on particle size, with the smallest droplets being formed below 60 % of VOR. Food-grade non-ionic surfactants (Tween 80 and Span 80) were used as an emulsifier. The effect of f on the droplet size distribution has been studied. In our system, the droplet volume fraction, given by the oil volume fraction plus the surfactant volume fraction, was varied from 0.1 to 0.3. The droplet diameter remains less than 350 nm when O/S is fixed at 1:1. The droplet size increases gradually as the increasing the volume fraction. Particle size could also be reduced by increasing the temperature when water was added to oil/ surfactant mixture. By optimizing system composition and homogenization conditions we were able to form VE-loaded nanoemulsions with small mean droplet diameters (d < 50 nm). The PIC emulsification method therefore has great potential for forming nanoemulsion-based delivery systems for food, personal care, and pharmaceutical applications.

This study purposed to examine how the window display of flower shops affects consumers' buying desire, and for this purpose, we surveyed flower buying customers' interest in window display according to their gender, age, and occupation. The survey was conducted using a questionnaire with flower shop customers in Seoul, Daegu, and Gyeongju. Interest in window display was over 1.5 times higher in women than in men. Among criteria for choosing a flower shop, window display was more important than other factors. With regard to experience of being stopped by unique window display, many of the respondents replied that they had such an experience, and the frequency was higher among women than among men. Among different types of window display, theme-type window display was most effective in stimulating customers' curiosity and buying desire. According to occupation, housewives showed particularly high interest in window display. The results of this study show that the window display of flower shops has a significant effect on consumers' buying desire.

The toxicity of perilla-chinese Basil, Perilla frutescens whole plant-derived materials to third-instar of larva Plutella xylostella was examined using that of four insecticides and 5 constituents of P. frutescens from other research materials. The active principle of P. frutescens was identified as the sesquiterpenoids α-farnesene by spectroscopic analysis. In leaf-dipping bioassay, α-farnesene (LD50, 36.9) was 3.9 times more toxic than β-farnesene (LD50, 145.2) against P. xylostella larva, based on 48h LD50 values. This compound was less toxic than insecticides. Naturally occurring α-farnesene merit further study as potential diamond back moth control agent.

As a major component of cuticle wax, cuticular hydrocarbon plays key roles as a chemical cue among inter- and intra-species in some beetles like as pheromone and alleolochemicals in addition to the physical function. In this study, cuticular hydrocarbon was analyzed and compared with three species of beetles adult, Monochamus alternatus, M. saltuarius belong to the Monochamus sp., and belong to the same class, Moechophyta diphysis, a typical vector of pine wilt disease. The composition of cuticular hydrocarbon of three species of beetles adult did not show the difference between male and female in intra-species, however, showed the difference in inter-species. They also differed from carbon numbers in inter species as 25-32 in M. saltuarius, 25-35 in M. alternatus, and 23-31 in M. diphysis. Major constituent of M. saltuarius was analyzed as n-C25, 2 or 4 MeC26, 9-C25:1, n-C27, 4-MeC28, n-C29, (9,x)-,and/or (11,x)-diMeC29; those of M. alternatus were n-C25, n-C27, 4-MeC28, n-C29, (9,x)-, and/or (11,x)-diMeC29, 9-C29:1, n-C29, (9,x)-,and/or (11,x)-diMeC29; and those of M. diphysis were n-C25, n-C26, n-C27, 3-MeC27,9-C29:1, 11-MeC29. The contents of n-alkanes were as follows: M. saltuarius ≒ M. alternatus > M. diphysis. The contents of monomethylalkanes were as follows: M. diphysis > M. saltuarius ≒ M. alternatus. The contents of dimethylalkanes were as follows: M. saltuarius ≒ M. alternatus > M. diphysis. And the content of olefine in female were analyzed as follows: M. saltuarius > M. alternatus ≒ M. diphysis, and the male's contents were similar in three kinds of beetles.
