이양희,양익환 한국농화학회 1970 Applied Biological Chemistry (Appl Biol Chem) Vol.13 No.3

Studies were carried out to develope the most economical and practical methods of packaging and preservation of kimchi, so commercialization of kimchi manufacture could proceed rapidly. The results obtained may be summarized as following. (1) It is generally established that the acceptable range of lactic acid content of kimchi is between 0.4% and 0.75%. Based on sensory evaluation, kimchi having lactic acid content below 0.4% and above 0.75% was not edible, and the time of optimum taste corresponded to the vicinity of 0.5% of lactic acid content. For the refrigeration storage with or without preservatives, the packaging kimchi in plastic film must be done at the lactic acid content of 0.45%, for lactic acid fermentation will continue slowly after the packaging. However, for the heat sterilized kimchi the packaging should be done at the 0.5% of lactic acid content for the best because lactic acid fermentation is completely stopped after the packaging. (2) Polyethylene, polypropylene, and polycello were chosen as suitable packaging materials. Polyethylene is cheapest among them but kimchi packaged in this film was damaged frequently in handling process and gave off kimchi flavor. On the other hand polypropylene also gave off kimchi flavor, but its higher mechanical strength gave better protection to kimchi and it had superior display effect due to the transparancy. Therefore polypropylene made much better packaging material. Polycello proved to be the best packaging material from the standpoint of physical characteristics but its price is higher than that of other plastic films. To be effective, the thickness of plastic films for packaging kimchi must exceed 0.08㎜. (3) Keeping property of kimchi appeared to be excellent by means of freezing. However, by the time the frozen kimchi was thawed out at room temperature, moisture loss due to drip was extensive, rendering the kimchi too stringy. (4) Preservation of kimchi at refrigerated temperatures proved to be the best method and under the refrigerated condition the kimchi remained fresh as long as 3 months. The best results were obtained when kimchi was held at 0℃. (5) In general, preservatives alone were not too elective in preserving kimchi. Among them potassium sorbate appeared to be most effective with the four fold extension of self-life at 20℃ and two fold extension at 30℃. (6) In heat sterilization the thickness of packaged kimchi product had a geat effect upon the rate of heat penetration. When the thickness ranged from 1.5 to 1.8㎝, the kimchi in such package could be sterilized at 65℃ for 20 minutes. Kimchi so heat treated could be kept at room temperature as long as one month without apparent changes in quality. (7) Among combination methods, preservation at refrigerated and heat sterilization could be favorably combined. When kimchi was stored at 4℃ after being sterilized at 65℃ for 20 minutes, it was possible to preserve the kimchi for more than 4 months.

감정 표현 음성을 합성하기 위하여 본 연구에서는 감정 음성 데이터의 피치와 지속시간의 음절 유형별 및 어절 내 음절 위치에 따른 변화를 분석하였고, 스펙트럼 포락이 감정 변화에 어떤 영향을 미치는지를 분석하였다. 그 결과, 피치와 지속시간의 음절 유형별, 어절 내 음절 위치에 따른 변화와, 스펙트럼 포락 등도 감정 변화에 영향을 미치는 것으로 나타났다. 또한, 감정 음성의 음향학적 분석 결과를 적용하여 감정 음성을 합성하고, 평상 음성의 음운 및 운을 파라미터 (피치, 에너지, 지속시간, 스펙트럼 포락)를 조절함으로써 감정 음성을 생성하는 감정 편집기를 구현하였다. For synthesizing speech with emotion, in this paper, the relationship between the change of emotional and the pitch of emotional speech data, phonetic type, position in syllable duration has been researched. The effects of emotional change by spectrum forac also has been analyzed. From this study, we found the change of the pitch, phonetic type and phonetic position in syllable duration, and spectral envelope give effects to emotional change. The emotional speech has been synthesized using the result of phonetic analysis of emotional data. The emotional Editor Program that produce emotional speech are is successfully realized by controlling prosodic and phonetic parameters(pitch, energy, syllable duration, and spectral envelope).

To generate a segmental duration rule for Korean speech synthesis, duration control factors were statistically analyzed using speech data with three tempos(fast, normal, slow) from seven speakers. Using spoken sentences with three tempos, I statistically analyzed the effects of the syllable type, the phoneme category, the neighboring phonemes, the position in utterance and utterance length(in syllable) according to tempos. Through prediction experiments using a regression tree model, the multiple correlation between observed and predicted segmental durations turned out to be 0.74 for unseen data and duration residuals turned out to be less than 25ms for above 75% of all phonemes.

The Nutritional evalution of the textured soybean protein added chopped meat product is carried out by chemical Analysis and feeding text with albino rat. The results obtained could be summarized as follow : 1) The exxential Amino acid pattern of T.S.P. added chopped meat product is variable depend upon the proportion of meat and T.S.P. ; especially T.S.P. is very limited in Methioninecystine that increase of the proportion of T.S.P. in the meat product emphasize the lack of sulphu containing amino acids. 2) In the case of body weight gain, the group of T.S.P. 20% indicated almost same rate with that of pure meat group, the groups of T.S.P. 70~90% revealed the simillar level of standard group and the groups of T.S.P. 30~40% maintained the intermediate level between the pure meat group and standard group. However, the pure T.S.P. group demonstrated very poor body weight gain. 3) In regard to the diet efficiency and the protein efficiency, the pure T.S.P. Group showed very poor effieciency however, in case of T.S.P. mixed with meat more than 10%, all groups maintained superior level to that of standard group. 4) The absorption rate is a little decreased by the addition of T.S.P. to meat products. 5) Concerning the protein retention rate, all groups in which contain the T.S.P. including pure T.S.P. group indicate superior rate to that of standard group. 6) Any significant physiological disorder effects of T.S.P. are not found.

일⋅가정양립제도가 대학생의 직장선택에 미치는 영향

이양희,오인하 한국혁신학회 2019 한국혁신학회지 Vol.14 No.2

The time spent in university is viewed as a preparation period for various job opportunities in the future. However, as employment is becoming unstable due to the flexibility in the labor market, there is an increase in unemployment of young adults such as university graduates who struggle from the lack of employment. As a result, there is a growing number of single male and female who push off marriage and having children or evade it. This result appears as an unprecedented birth rate drop. As an alternative to increase youth employment rate and birth rate at the same time, it is considered necessary to recognize work and family balance system and substantialize a system fitting to the period. This study targeted on 394 university students and conducted a survey asking about awareness of work and family balance policy and also preferences in a virtual workplace where work and family balance system is executed. For the analysis method, conjoint analysis that applied a logit model was conducted. The main results of this survey are as follows. The results indicate that the availability of salary of 0.51 million won when working hours per week are reduced by one hour. The results indicate that the availability of parental leave provides benefits equivalent to an increase of 9.01 million won in annual salary and that offering childcare center in the workplace has an effect equivalent to an increase of 5.58 million won, flexible working hours also has 5.07 million won, large company more receive a benefit of 4.34 million than small and med_sized enterprises in annual salary. In comparison of personal preferences depending on students' nature, male students preferred working for a large company, but female students appeared to be more interested in companies that provide parental leave and flexible working hours. As students' grade level was lower, they were more interested in companies that provide parental leave and flexible working hours. However, it appeared that students with higher grade and majoring in humanity, social science, and art and physical education preferred a workplace that offered parental leave. The research displayed that household income and residential area did not cause an influence on the preference of the workplace that executes work and family balance system. 대학생의 시기는 미래 직업을 준비하기 위한 다양한 취업준비를 하는 기간이라고 볼 수있다. 그러나 노동시장의 유연화로 인해 고용이 불안정해지면서 구직난에 시달리는 대학졸업자 등의 청년 실업률이 늘고, 이에 따른 결과로 결혼과 출산을 미루거나 기피하는 미혼남녀들이 늘어나고 있다. 이러한 결과는 사상초유의 출산율 저하로 나타나고 있다. 청년고용율과 출산율을 동시에 향상시킬 수 있는 대안으로 일⋅가정양립제도에 대한 인식확산 및시대에 맞는 제도의 내실화가 필요한 시점이다. 본 논문에서는 대학생 394명을 대상으로일⋅가정양립정책에 대한 인식 및 향후 직장을 선택할 때 일⋅가정양립제도가 시행되는가상의 직장에 대한 진술선호를 묻는 설문을 시행하였으며, 분석방법으로는 로짓모형을 이용한 컨조인트 분석을 실시하였다. 본 설문을 통하여 도출한 주요 결과는 다음과 같다. 주당근무시간 1시간이 줄어드는 것은 연봉 약 51만원이 증가하는 효용이 있으며, 육아휴직은약 901만원, 직장어린이집 있는 경우는 약 558만원, 유연근무제도 시행 직장은 약 507만원의연봉을 더 받는 것과 같은 효용이 있다. 대기업에 다니면 중소기업에 다니는 것보다 약 434 만원의 연간 급여를 더 받는 효용이 있는 것으로 추정되었다. 학생들의 특성에 따라 선호도를 비교하여보면 남학생은 대기업을 선호하고, 여학생은 육아휴직, 유연근무가 시행되고있는 기업에 관심이 많은 것으로 나타났다. 학년이 낮을수록 육아휴직과 유연근무제도 시행직장에 관심이 많고, 학점이 높을수록, 공학계열 외 전공 학생이 육아휴직 시행 직장을 선호하는 것으로 나타났다. 가구소득수준과 거주하는 지역은 일⋅가정양립제도 시행 직장 선호에 영향을 미치지 못하는 것으로 조사되었다.
