White blood cells (WBCs) are present in most human ejaculates, but abnormally high concentration of seminal leukocytes map reflect an underlying pathological condition. The World Health Organization (WHO) has defined leukocytospermia as status of more than 10^(6) WBC/mL of semen. The purpose of this study was firstly, to compare the outcomes between conventional IVF and ICSl in leukocytospermia, and secondly, to investigate whether ICSI may be an alternation treatment for patients with leukocytospermia. Total 346 cycles of conventional IVF and ICSI candidates underwent IVF cycles at Eulji Hospital Infertility Clinic. Semen Parameters including concentration, motility, morphology of spermatozoa and concentration of leukocytes were assessed from the raw ejaculates. There was no difference in sperm concentration, motility and morphology. The rates of fertilization and good embryo development from ICSI were significantly higher than those from conventional IVF in leukocytospermia (60.4% & 32.5% respectively for ICSI group and 44.4% & 28.5%, respectively for IVF group, P<0.001). The pregnancy rate after ICSI was also higher than that from conventional IVF (34.0% vs 29.1%. P<0.05). These results indicate that the presence of seminal leukocyes (>1×10^(6) WBC/mL of semen) is adversely related with fertilization, embryo development and pregnancy rate. Therfore the measurement of seminal leukocytes in routine semen analysis appears to be of prognostic value with regard to male fertilizing potential. In conclusion. it is suggested that ICSI is an alternative choice of treatment for patients with leukocytospermia.

Ge-doped multicomponent oxide glasses were prepared by a conventional melting method. The structural change around Ge ions was investigated by using PL(photoluminescence) and conductance(G). After UV irrdiation, the PL intensity decreased and the change were maintained at room temperature, but a photodarkened glass recovered near its original properties when it was heat-treated at 500℃ for several hours. The conductance of the irradiated sample decreased because the disorder in structure was happened by UV irradiation. These results can be explained a structural change were occurred at bonding structure between Ge ions and glass components.

Objectives : This research attempts to investigate the relationship between health risk factors and workers' behavioral changes based on individual worker's characteristics to allow the development of more effective health promotion programs in businesses places. Methods : A questionnaire survey was conducted with 282 workers employed in small to medium sized enterprises in the Kyong-in area of Korea. The questionnaire was composed of general characteristics, a health risk assessment and an evaluation of the stage of behavior change for health promotion strategy in the workplace. Results : The health risk assessment revealed that 65.7 % of male workers smoke, 70.5% of male workers do not exercise on a regular basis, 86.1 % of female workers do not exercise at all, and 78.6 % of male workers and 50 % of female workers drink alcohol. In addition, the survey identified that 29.5% of male workers are addicted to excessive drinking, as are 11.1% of female workers. Based on the four stages of behavioral changes that lead to health, the pre-contemplation stage, contemplation stage, action stage, and maintenance stage, 40.5 %, 23.7 %, 12.1 % and 23.7 % of workers are in these stages, respectively, with regards to quitting smoking. As for regular exercises, 18.4 %, 37.6 %, 17.7 %, and 26.3 % of workers belong to each stage, respectively. As for moderation in drinking, 20.9 %, 15.4 %, 10.0 %, and 53.7 % are in each stage, respectively. The rate of health managers in the active stage of quitting smoking is significantly higher than that of general workers. Among the workers who do not exercise on a regular basis, workers over 50 years-old and blue color workers are more common in the precontemplation stage than any other worker groups. Conclusions : The results of this study suggest that the stages of behavioral change vary with worker characteristics. An awareness of the effects of the high risk factors is essectial for promoting workers' attendance in health promotion programs.

It is well known that high fat diet enhances using of fatty acids during the last stage of endurance exercise. But effects of high fat diet administration on endurance exercise were not well documented. At this point of view, we ingested intralipose and a high fat diet in rats to increase fatty acids utilization during endurance exercise performance. Thirty male Sprague-Dauley rats were chosen as the subjects in this experiment. These subjects were divided into two groups on the basis of diet protocols as follows : ① normal diet(carbohydrates 58%, proteins 23.8%, lipids 8%, and others), ② high fat diet(carbohydrates 45%, proteins 25%, lipids 30%). And in high fat diet group, intralipose was ingested before exercise. Endurance exercises on the basis of Bruce protocol were applied to the groups. Serum glucose, lactic acid, FFA, TG, cholesterol concentration were analyzed. Liver, soleus and gastrocnemius white muscle glycogen contents were determined and endurance exercise time was measured. As a result of experiment, high fat diet group was decreased less than normal diet group in serum glucose concentration and in liver, soleus and gastronemius white muscle glycogen contents. On the other hand, serum FFA and TG concentration were increased more high fat diet group than nomal diet group, and serum lactic acid concentration were increased less high fat diet group than normal diet group. And endurance exercise time was increased after a single high fat diet. In conclusion, even though a single high fat diet, glycogen-sparing effect in rats was occurred.

Purpose : This study aimed to identify the range of normal facial asymmetry using three-dimensional CT and to develop a simple method of diagnosis of facial asymmetry. Materials and Methods : Twenty eight adults with normal occlusion (16 males and 12 females; mean age 24 years and I month) were selected, whose faces were assessed to be symmetric by an orthodontist. Three-dimensional reconstructions were obtained utilizing spiral CT scans and an oral and maxillofacial radiologist, evaluated nineteen anatomic landmarks in three-dimensional coordinates. Facial asymmetry index of each landmark was caluculated. Results : The range of normal facial asymmetry of each landmark was identified using mean and standard deviation of facial asymmetry index. Conclusions : The range of normal facial asymmetry identified in this study may be used as a diagnostic standard for facial asymmetry analysis. (Korean J Oral Maxillofac Radiol 2007; 37: 45-51)

다운증후군 환자의 치아우식증과 구강내 여러 요인들과의 연관성을 평가하고자 9-18세의 다운증후군 환자 25명과 정상인 63명을 대상으로 치아우식경험지수, 치태지수를 조사하고 효소면역분석법을 이용하여 타액의 면역항체 IgA와 뮤탄스 연쇄상구균-특이 IgA 농도를 측정하고, Dentocult 키트를 이용하여 뮤탄스 연쇄상구균과 유산간균의 수, 타액의 완충능을 측정하여 두 군의 각 값들을 독립 t-test와 카이제곱 검정을 시행하였다. 다운증후군 환자에서 유치우식경험은 정상인에 비해 유의하게 낮았으나(p<0.001), 영구치우식경험은 유의한 차이를 보이지 않았다. 치태지수와 타액의 IgA의 농도는 두 군 간에 차이를 보이지 않았으며, 뮤탄스 연쇄상구균 특이-IgA 농도와 타액 완충능은 다운증후군환자에서 낮았다(p<0.05), 뮤탄스 연쇄상구균 수와 유산간균 수는 두 군간에 유의한 차이는 없었다. 9-11세 군에서 뮤탄스 연쇄상구균의 수는 다운증후군 환자에서 정상인보다 낮았으며(p<0.001), 뮤탄스 연쇄상구균 특이-IgA는 다운증후군 환자에서 유의하게 낮았다(p<0.05), 유치의 치아우식경험치면지수는 완충능, 뮤탄스 연쇄상구균의 수와 유의한 상관관계를 보였다. This study investigated the relationship between dental caries and various oral factors in subjects with Down' s syndrome. We compared 25 subjects with Down's syndrome with 63 healthy control. The dental caries index and plaque index were examined, and the total salivary immunoglobulin A and S. mutans specific salivary immunoglobulin A concentration were measured using ELISA. The S. mutans counts, Lactobacillus counts and buffer capacity were measured with Dentocult test medium. The decayed and filled surface index of deciduous teeth in subjects with Down' s syndrome was lower than in controls(p<0.001). The plaque index and total salivary immunoglobulin A concentration showed no difference, S. mutans specific salivary immunoglobulin A concentration and buffer capacity in subjects with Down' s syndrome were lower than in controls(p<0.001). There was no significant difference between two groups in the S. mutans counts and Lactobacillus counts. In 9-11 year age group, S. mutans counts in subjects with Down' s syndrome was lower than in controls(p(0.001) and S. mutans specific salivary immunoglobulin A concentration was lower(p(0.05). There was a high correlation among deciduous dental caries index and buffering capacity and S. mutans counts.

1930년대 강소천의 동요,동시에 나타난 동심성(童心性)

강정구 ( Jeong Gu Kang ),김종회 ( Jong Hoi Kim ) 한국문학연구학회 2015 현대문학의 연구 Vol.0 No.55

1930년대 강소천의 동요 · 동시에 나타난 동심성은 당대의 주요 문인집단이 지향했던 순수 관념의 아동문학적인 구체화였다. 1930년대의 주요 문인집단은 세상에 대한 판단중지를 통해 미와 예술적인 열정에 심취한 순수 관념을 지향했는데, 1930년대에 출현한 주요 동요 · 동시시인들은 그러한 순수 관념을 아동문학적인 장르적인 특성에 맞게 어떻게 전유 · 형성하는가 하는 과제를 감당했다. 그 중에서 강소천은 그의 동요 · 동시시집 『호박꽃초롱』에서 당대의 동요 · 동시시인들이 감당했던 아동문학사적인 과제의 한 응답으로써 순수=동심의 문학을 잘 보여줬다. 강소천의 동요 · 동시시집 『호박꽃초롱』은 1930년대의 순수 관념을 동심으로 전유한 대표적인 작품집이었다. 무엇보다 그의 동요 · 동시시집에서는 사회적인 관계를 벗어난 사적인 아동과 세계를 형상화했다. 다만 이러한 형상화는 1920년대에 등단한 동요 · 동시시인들과 다른 순수한 아동 화자와 그 화자가 바라보는 세계를 재현해내는 데에 성공했지만, 사회 · 국가 · 민족의 이데올로기에 대해서 암묵적으로 동조 · 추종 · 무관심했다는 점에서 비판의 대상이 되었다. 그리고 그의 동요 · 동시시집에서는 순수한 언어의 관념을 전유해서 아동이 사용하거나 사용할 법한 언어를 탐구 · 제작했다. 언어의 물질성 · 기표성 그 자체에 대한 관심이 깊어졌고, 1920년대의 전통적인 율격에 대한 발전과 파격이 엿보였다. 1920년대의 동요 · 동시시인들과 비교해 볼 때에 이러한 강소천의 문학적인 변모는 분명히 1930년대의 새로운 문학적인 흐름에 동참하는 것이 아닐 수 없다. 1930년대에 순수 관념을 지향한 문학은 문학이 문학다워야 한다는 내향적이고 자기완결적인 주장을 하면서 미 자체에 대한깊은 관심을 보여주고 언어조형과 비(非)세속적인 순수 관념에 대한 새로운 지평을 열어놓았음에도, 그것이 근대자본주의의 중산층 · 부르주아 이데올로기와 특권의식을 보여줬다는 비판에서 자유로울 수 없었다. 강소천의 아동문학 역시 이러한 공과를 함께 지니는 아동문학적인 한 현상이다. The child``s mind in Pumpkin flower lanterns written by Kang, So-cheon is relative to poetry-literature group who is Bak, Yongchel and Kim, Yeong-rang. They pursued the purity which is away desires and power and politics of world, and it is trademark of poetry-literature group. Poets of 1930’s in field of children literature seek the purity that is insisted by poetry-literature group. The purity which is searched by Kang, So-cheon is the pure child``s mind. The pure child``s mind of Kang, So-cheon in the 1930’s is distinguish from Bang, Jeong-hwan and Yun, Seok-gung’s children’s verse. Kang, So-cheon’s children’s verse is new. His children in Pumpkin flower lanterns are away desires and power and politics of world, but Bang, Jeong-hwan and Yun, Seok-gung’s children in their children’s verses are social children. His world in the text is pure human, animal, and plant. Also Kang, So-cheon’s language is new from Bang, Jeong-hwan and Yun, Seok-gung’s children’s vers in the 1920’s. His poetic language is emphasized to matter itself of language. The meaning isn’t important. And His rhythm is odd than children’s rhythm, but characteristic.

Hoi-Yun Kim,Young-Min Song,Sang-Keun Jin,Il-Suk Kim,Yang-Su Kang,Sung-Dae Lee,Rekha Chowdappa,Ji-Hee Ha,Seoc-Mo Kang 아세아·태평양축산학회 2006 Animal Bioscience Vol.19 No.2

The objective of the present study was to investigate the effects of growth performance, chemical composition and meat quality parameters by the addition of fermented persimmon shell diets (FPSD). The experimental animals were ninety-six Berkshires. The pigs were allotted at 8 per pen in front-open building with three replicate pens per treatment. Until 61짹1 kg live weight at 140 days, the animals were fed growing diet, after which, experimental samples were fixed at 0, 3, 5 and 7% FPSD as C, T1, T2 and T3 in the finishing diets. Pigs of 103짹1 kg live weight were slaughtered by electrical stunning. In growth performance, ADG increased more (p<0.05) in T2 than C and T1. ADFI (kg/day) was higher (p<0.05) in T2 than in other groups. Feed conversion ratio was lower (p<0.05) in T2 than in other groups. On longissimus dorsi muscle (LM), the content of moisture was lower (p<0.05) in T3 than in other treatments. Crude fat increased (p<0.05) by addition of FPSD. pH at 24 h (pH24) decreased more (p<0.05) in T2 and T3 than C and T1 by addition of FPSD. WHC decreased (p<0.05) by addition of FPSD. In meat, Hunter L* and a* were lower (p<0.05) in C than in other treatments. Hunter b* was higher (p<0.05) in T3 than in other treatments. In back-fat, Hunter L* was higher (p<0.05) in C than in other treatments. Hunter a* was not different in C and T1 but increased (p<0.05) in treatments by addition of FPSD. Hunter b* increased (p<0.05) by addition of FPSD. In sensory evaluation scores, for fresh meat, the value of meat color was higher (p<0.05) in T2 and T3 than in C and T1. The value of marbling was lower (p<0.05) in C than in other treatments. The value of drip loss was higher (p<0.05) in C than in other treatments and was lower (p<0.05) in T2 and T3 than in other treatments. The results of cooked meat, the value of tenderness was not different in C and T1 but increased (p<0.05) in other treatments. The value of flavor was significantly higher (p<0.05) in T2 and T3 than in C and T1. The value of overall acceptability was increased (p<0.05) by addition of FPSD. Hence we can conclude that addition of FPSD affected growth performance and meat quality parameters, in particular, it improved crude fat, hunter L* and b*, and sensory evaluation on pork and was also seen to affect pH24 and WHC. FPSD can be used for improvement of meat quality parameters.
