난 발생 및 난 성숙을 위한 난소내의 제어기능의 이해는 흥미로운 연구대상이다. 그러나, 난포에 의하여 지엽적으로 분비된 어떤 스테로이드 물질도 난 발생 및 난 제어를 위해 관여하지 않는 것으로 알려져있다. 따라서, 난소내의 조절인자가 어떻게 난 발생 및 난 성숙을 위해 작용하는지를 구명하는 것은 난 발생 및 난 성숙을 위해 매우 중요한 연구과제라 할 수 있다. 본 총설에서는, 본 연구실의 최근의 업적을 중심으로 포유동물의 난 발생과 난 성숙을 위한 난소내의 조절인자에 대하여 정리하였다.

The purpose of this study was to develop and validate an imagery-focused music listening program for improving emotion regulation among infertile women. For the program development in this study, the literature on emotional issues and coping strategy of infertile women was analyzed to establish theoretical foundation; and the literature on Supportive Music and Imagery (SMI) was analyzed to identify intervention components. Based on the established theoretical framework, the program was developed and finalized after evaluation of validity by four SMI professionals. The developed program was found to systematically target changes in emotions in the step-wise process of discovery, reinforcement, and affirmation of positive emotional resources. The list of music for future use was also identified and presented after systematic analysis of musical features in relation to valence and arousal of emotions. The imagery-focused music listening program was an initial approach to infertile women with SMI, which indicates the possibility of extended application for broadened clinical population.

Mammalian eggs are ovulated arrested at meiotic metaphase II until fertilization. Generally in mammals, fertilization results in a series of intracellular calcium oscillations that are mediated by inositol triphosphate (IP$^3$) or cyclic adenosine diphosphoribose (cADPr). The high levels of maturation promotion factor (MPF) within the cell decrease, pronuclei form, the cytoskeleton is reorganized and proteins are post-translationally modified. If all is normal, the newly formed embryo initiates the developmental program specific to that species. Artificial methods of producing these effects in pig oocytes are discussed. One potential mechanism mediated via a signal transduction pathway is present in pig oocytes. Stimulation of this pathway leads to the early events following fertilization, and electrical stimulation leads to apparently normal de v velopment to day 12. Further studies are needed to determine which mechanism(s) the sperm uses to initiate development.

A combination of ultraviolet irradiation and egg rotation was applied to Korean frogs to study the mechanisms of the establishment of the dorsal-ventral polarity. Rotation of the uncleaved egg was capable of preventing the characteristic syndromes associated with UV irradiation. As well, brief rotation of the egg before cleavage relocates the site of dorsal lip to a novel location in the embryo at gastrula stage. That is, the dorsal lip appeared on the opposite side to gravity at the rotation of the egg. Above results were discussed with the informations obtained from other anuran and urodele species, and were interpreted in terms of regulating mechanisms for early embryogenesis.

대부분의 어류는 난과 자치어기를 지나 성어가 되면서 어장에 가입되므로 어란과 자치어의 분포밀도는 성어자원량을 파악하는데 중요하다. 일반적으로 물리적 환경 즉 수온과 해류는 어류 자치어의 분포, 성장 및 생존에 영향을 미치는 주된 요인으로 표층수온은 난의 발달과정을 조절하고 해류는 유영력이 미약한 자치어의 분포와 출현량에 영향을 미친다. (중략)

Purpose: The purpose of this controlled study was to determine the effectiveness of vision therapy for accommodative infacility in children. Methods: 10 children 9 to 13 years of age with symptomatic accommodative infacility were divided into a treatment group (n=6) and a contol group (n=4). The treatment group received 12 weeks of vision therapy while the control group received nothing. Results: The visual symptom assessed by COVD-QOL score for the treatment group showed both statistically and clinically significant reduction from 27.50${\pm}$5.68 to 12.00${\pm}$7.24 (p<0.01). Also, there were statistically and clinically significant improvement in the clinical measures of monocular accommodative facility of right eye (from 0.67${\pm}$1.03 cpm to 15.42${\pm}$4.85 cpm; p<0.001) and binocular accommodative facility (from 0.33${\pm}$0.82 cpm to 13.92${\pm}$3.58 cpm; p<0.001). In contrast, there were no significant improvement in symptoms and in the clinical measures of monocular and binocular accommodative facility for the control group (p>0.05). Conclusion: Vision therapy is an effective mode of treatment in eliminating symptoms and improving accommodative facility in children with accommodative infacility.

우리나라에 있어서 양액재배는 지금으로부터 40년전으로 거슬러 올라간다. 그러나 현재의 발전수준은 양액재배가 발전된 나라들에 비하면 특히 그 수준이 저조한 상태에 머물고 있다. 그러나 최근에 들어 그러한 현상은 농민을 에워싼 환경의 변화에 따라 크게 자극을 받고 있다. 시설원예의 일부가 양액재배로 전환되어 가는 일이 전국적으로 확산되어가고 있다. 이러한 현상은 마치 사람이 깊은 잠을 자고 난 후에 다시 활발한 활동을 시작하는 것처럼 지구상의 생물의 주기적인 활동현상과 유사해서 장래의 발전에 기대가 된다. (중략)

Spawning behaviors of Squalidus gracilis majimae (Cyprinidae) were observed in the laboratory whose environmental factors such as light (D/L = 16 : 8), temperature ($20\;{\sim}\;24\;＾{\circ}C$), and dissolved oxygen (>8 mg $L^{-1}$) were quite regularly controlled. The behavioral patterns were categorized into three stages ofpre-spawning, spawning, and Post-spawning behaviors. In Particular, the pre-spawning stage was specified by 11 specific behavioral patterns of aggressive mating behaviors. During the spawning stage, the male and female performed four distinct spawning behaviors including sexual temptation, stimulation, egg spawning, and the separation, and randomly laid about 200 ${\sim}$ 300 eggs on the bottom substrates through the night. After finishing spawning, two adults separated toward their refuges and showed 3 types of post-spawning behaviors such as the resting, occasional eggs protecting, and the egg eating. The fish was identified as a partial-parental care species after the spawning.

Titanium과 Ruthenium의 비율(Ru/Ti = 0.01, 0.03, 0.05, 0.07)을 조절하여 Ruthenium이 도입된 산화타이타늄($TiO_2$)를 수열합성법을 이용하여 합성하였다. TEM 이미지를 통하여 네모난 형태의 나노입자를 확인하였으며 XRD 패턴과 ICP 원소 분석을 통하여 Anatase 형태와 각각 다른 양의 Ruthenium이 도입된 것을 확인하였다. 본 연구에서는 Ruthenium이 도입된 산화타이타늄을 이종상촉매로 사용하여 Benzyl alcohol 및 Benzyl amine의 산화반응에 적용하였으며 특히, Ru/Ti = 0.03인 촉매가 가장 우수한 활성을 보였다.

생식선자극호르몬 (GTHs; FSH/LH)은 어류의 생식계를 조절하는 상위의 호르몬 이며, 난황형성 및 생식세포의 분화/발달을 촉진하는 중추적인 기능을 담당한다. 그러나, 해양의 환경오염물질이 어류 GTH의 유전자발현에 미치는 영향에 관한 연구는 매우 부족한 실정이다 (Khan et al., 2001; Yadetie and Male, 2002). 본 연구에서는 난태생 어류인 조피볼락 뇌하수체 호르몬의 유전자 발현에 미치는 내분비계 장애물질의 영향에 관하여 조사하였다. (중략)
