The purpose of this study is to find out the need for sex education of middle school students and their parents. For the data collection, the survey was conducted during the period from September 10 to September 20, 1989 by using prepared questionnaire. A questionnaire was given to 592 students of 1st, 2nd and 3rd grade from four middle schools and to 408 their parents in Suwon City. The major results are summarized as follow; 1. Among the 25 questions were asked about knowledge of sex, the structure of reproductive organs, physical change during puberty, menstruation, Sexually stimulation and family plan were answered correctly by over 50% of the students. The higher the grade, the more the knowledge of sex. There was no significant difference between this knowledge and with eider sister or brother. Among the 20 questions were asked about knowledge of sex, sexually stimulation, pregnancy, emission, induced abortion and sexually transmitted disease were answered correctly by over 50% of the parents. 2. 30 questions were asked about attitude of sex, 47.7% of the students and 53.4% of the parents answered 'positive'. There was no significant difference between grade and sex of students. A significant difference '.vas not also found between years and education level of parents. 3. In case of students, experience of sex education was showed the structure of reproductive organs, physical change during puberty, temper during puberty, menstruation, emission more. In the event of parents, experience of sex education was showed the structure of reproductive organs, temper during puberty, menstruation, emission, relationship with apposite sex more. Most students felt that sex education should begin from the first grade of middle school and the first grade of high school strongly. In parents was showed the need for sex education from the primary school and the first grade of middle school highly. Namely, students and parents felt that sex education should begin from puberty. To help good developments and growth of middle school students with rapid change should be educated sex eduction properly for the occasion.

최순희,승오탁,이명선,Choi, Soon-Hee,Seung, O-Tak,Lee, Myung-Sun 한국응용과학기술학회 2019 한국응용과학기술학회지 Vol.36 No.2
본 연구는 동충하초 추출물을 PC12 및 BV2 세포에서 인지능력 개선에 대한 효능을 평가하고자 하였다. 동충하초 추출물을 증류수로 추출하여 PC12 및 BV2 세포로 MTT 분석을 통해 세포 생존율을 확인하고 L-glutamate로 유도한 PC12 세포를 통해 세포 보호 효능과 아세틸콜린 함량 및 아세틸콜린에스테아제 활성을 평가하였다. 또한, LPS로 유도한 BV2 세포를 통해 nitric oxide (NO) 및 prostaglandin E2 (PGE2) 생성량 등의 항염증 효능을 측정하고 western blot 분석을 통해 $NK-{\kappa}B$, p38, JNK, caspase-3 등의 단백질 발현량을 확인하였다. 동충하초 추출물은 $200{\mu}g/m{\ell}$ 농도를 제외하고 1, 10, $100({\mu}g/m{\ell})$ 농도에서 세포 독성이 나타나지 않았다. L-glutamate로 유도한 PC12 세포에서 유의성있게 세포 보호 효능과 아세틸콜린 함량의 증가, 아세틸콜린에스테아제 활성 감소가 나타났다. 또한, 동충하초 추출물은 NO 및 PGE2 생성량과 $NK-{\kappa}B$, p38, JNK, caspase-3 등의 단백질 발현을 억제하였다. 이와 같은 결과는 동충하초 추출물이 인지능력에 대한 예방 및 개선 효능이 있음을 나타낸다. 따라서 동충하초 추출물은 인지능력 개선을 위한 새로운 천연 소재로 활용될 수 있다. The aim of this study is to evaluate the efficacy of cordyceps militaris extracts for the improvement of cognitive dysfunction in PC12 and BV2 cells. Cordyceps militaris extracts was prepared by extracting with distilled water. Cell viability was assessed by MTT assay using PC12 cells and BV2 cells. Confirmed effects of L-glutamate induced cytotoxicity test, Acetylcoline (ACh) concentration, and Acetylcolinestase (AChE) activity in PC12 cells. Anti-inflammatory activities of cordyceps militaris extracts was measured through changes in the levels of nitric oxide (NO), and prostaglandin E2 ($PGE_2$) on lipopolysaccharide(LPS)-induced BV2 cell. In addition, we measured the expression of $NF-{\kappa}B$, p38, JNK, and caspase-3 in western blot analysis. Cordyceps militaris extracts showed no cytotoxicity at the concentrations of 1, 10, and $100{\mu}g/m{\ell}$ except for the concentration of $200{\mu}g/m{\ell}$. Cordyceps militaris extracts protected the cell and exhibited significant increases in the ACh concentration and a significant decrease in the AChE activity in L-glutamate induced PC12 cells. Moreover, cordyceps militaris extracts inhibited the productions NO, and PGE2 level and the protein expression of $NF-{\kappa}B$, p38, JNK, caspase-3 in LPS-induced BV2 cells. These results indicate that cordyceps militaris extracts possible prevented and improved cognitive dysfuction symptoms. Thus, cordyceps militaris extracts may be a novel natural material option for the improvement of cognitive dysfunction.

Product quality and shelf-life effect of sodium lactate (SL) in combined with chitosans with various molecular weights (MW) in low-fat sausages (LFSs) stored at $10^{\circ}C$ were evaluated. LFSs with SL and chitosans had 75-76% moisture, 1-2% fat, and 15.8-17.1% protein with a pH range of 6.3-6.6. Water holding capacity was decreased, but most textural properties were increased with the addition of chitosan with MW of 30-40 kDa. Hunter a (redness) values were also increased with the addition of sodium lactate and chitosans in combination with laccaic acid at the level of 0.05%, resulting in similar Hunter a value of 150 ppm of sodium nitrite. The combination of SL and chitosans slightly extended the shelf-life of LFSs approximately 3-6 days at $10^{\circ}C$, resulting in inhibition the growth of L. monocytogenes and E. coli O157:H7, as compared to the control. However, the inhibition of microbial growth at $10^{\circ}C$ was not as strong as that at $4^{\circ}C$. Thus, the storage temperature should be as low ($<4^{\circ}C$) as possible to have a maximum antimicrobial activity in LFS containing SL and various chitosans.

The result of cleansing hairs using the product after permanent hair dye is given as follows. We can see that contaminations are removed by using white scalp materials and hair dye, rather than by using usual detergents. The results of measuring a color degree using a color meter step in terms of scalp and hairs before and after dye using the product are given as follows. The color degree, L* value, is 43.797, and red and yellow are included very much. However, after dyeing, the color degree of the scalp, L* value, is 29.925; the color of the scalp becomes dark; red is reduced. When we measured the color degree using the scalp cleansing product, the L* value is 37.198; the same color pattern is shown. The scalp has its bright color and is clean; especially the red portion is increased to recover it to its original form. However, there are little different color, comparing with the color before the dye (L* 17.693); the scalp cleansing product increase the brightness (L* 18.144); especially the portion of red is increased. Therefore, the collected results show that after the permanent dye, coloring hair chemicals are not removed after washing, but the specialized scalp cleansing product removes effectively the coloring hair chemicals and remaining.

최순희(Soon Hee Choi) SBS 2011 미디어경제와 문화 Vol.9 No.2
인터넷의 Web2.0 서비스는 개방형 서비스 구조로 누구나 자유롭게 참여하여 핵심가치를 창출하면서 기술 분야뿐만 아니라 사회 문화 전반에 영향을 미치고 있다. 본 연구는 SBS 라디오 <두시 탈출 컬투쇼(이하 컬투쇼)>를 중심으로 개방·참여·공유의 특성을 가진 Web 2.0의 기제들이 라디오 방송 프로그램의 제작 과정에서 어떤 방식으로 활용되고 있으며, 청취집단은 어떤 특성을 갖고 있는지 규명해 보고자 하였다. Web 2.0 환경에서 라디오 프로그램(컬투쇼)은 개방성이 무한대로 높아지며 참여형태가 다양한 청취자를 확보할 수 있는 구조를 갖는다. 인터넷, 모바일과 라디오가 융합되면서 짧은 시간에 대규모로 형성된 청취자 집단(프로슈머)은 감성과 지성, 윤리적 본성을 증폭시키는 공성(sym -ity)을 갖는다. 한편, 지상파 라디오 제작주체가 양질의 콘텐츠를 만들어내기 위해서는 콘트롤 타워의 역할이 더욱 요구된다. 사용자층의 참여가 광범위하고 산포되어 있기 때문에 프로그램 제작 과정에서 청취자의 기여는 제한될 수밖에 없는 한계를 지닌다. This study is to inquire into how the qualities of Web 2.0 such as openness, participation, and sharing are used in the process of production of radio programs(especially focused on the Escape from 2 o’clock, Cultwo Show), and into what the characteristics of the user group are. The research methods are the participative observation on the making and broadcasting of the program, the program monitoring, the in-depth interviews of the audience and the production crew, and the analysis of the contents posted in the SBS Gorealra web board. Under the circumstances of Web 2.0, radio program and the Internet or mobile services can be converged interactively, by which the great number of users(prosumers) can be formed and secured momentary, in other words, syndicated in a quantitative and qualitative way, who have symity in common which amplify the sentimentality, reason, and ethical sympathy. On the other hand, the role of control tower is indispensible in order that the maker of radio program produce a qualified contents. And as the audience group’s participation in the programs in scale is extensive and scattered, the group’s structured contribution to the process of producing a program can be quite limiting.
