본 연구의 목적은 기존 사법시험이 갖는 소위 ‘고시낭인’이 되어 역기능으로서 사회가 부담하고 있는 사회적비용을 감소시키고 법조인의 다양성과 전문적 지식을 법에 도입하기 위한 제도로서 법학전문대학원(law school; 로스쿨: 이하 ‘법전원’)이 갖는 장점에도불구하고 법전원의 고비용구조가 우리 국민 모두가 진입할 수 있는 법조영역에 대한 진입장벽이 되어 특정 소득계층이 진입하지 못하는 문제가 과연 존재할 수 있는지의 여부를 분석하고자 하는데 있다. 법전원이 출범했음에도 불구하고 지금까지 구체적인 분석이 이루어지지 않고 막연한 추측과 여론에 의하여 고비용구조이기 때문에 법조인이 되는데 진입장벽이 되고, 오히려 기존의 사법시험을 존치하여 문제를 해결하여야 한다는 주장이 많이 제기되고 있는 실정이다. 현재 국회에는 김용남 의원 등이 발의한 사시 존치 관련 법안 4건이 계류되어있다. 여기에 오신환 의원이 대표발의한 사시 존치 법안이 지난 6월 제출되어 법안소위 회부를 기다리고있는 상태다. 그러나 기존의 사법시험과 비교하여 얼마나 많은 비용차이가 발생하는지 구체적인 분석은 이루어진 적이 없다. 본 분석의 목적은 기존 사법시험제도와 법전원체제에 대한 가치판단의 문제에 대한 접근은 제외하고, 순수한 비용분석에 의하여 국민소득계층에서 법조계에 진입하지 못하는 소득계층이 존재하는지 여부를 비교분석하는데 있으며, 만일 존재한다면 어떠한 계층이 진입할가능성이 적은지를 분석하였다. 이러한 분석은 국민의 교육과 직업기회에 대한 형평성과 법조분야의 발전에 매우 중요한 의미를 갖는다고 할 수 있다. 따라서 본 비용분석은 법전원 출신의 변호사시험과 기존 사법시험과의 분석에서 측정 불가능한 요인은 배제하고, 측정 가능한 범위 내에서 비용의 총액과 차액분석을 통하여 비교하고, 법조인이 되기 위한 기회비용을 이용하여 비용의 차이를 비교 분석하여 소득계층의 진입가능여부의 판단기준을 제시한다는 것은 원가(비용)분석의 사례로서 큰 의미가 있다고 생각한다. The goal of this cost analysis is to explore and analyze, despite the advantages the new ``law school`` system, which reduces the social costs of the ‘entrance exam vagabond’ problem by solving this social issue the previous judicial bar entrance exam had, and allows the for the diversification of the pool of applicants and encourages professional knowledge in the law industry, if in fact there is a possibility that the cost structure of law school serving as an entrance barrier for certain socio-economic groups to apply to be a Judicial Officer is a problem that exists. Even though the law school system was established, there has not yet been a detailed analysis, and the reality is that through vague guesswork and media spin, the system is blamed as being of high cost and therefore the cause for being a high barrier of entry to certain socioeconomic classes to become a Judicial Officer, and that it also retains the problems of the previous judicial bar examination, so there are many opinions that these problems of the new law school system need to be solved. However, there has yet to have been a detailed cost comparison analysis to explore how much the cost difference is with the old judicial bar examination system. The goal of this analysis is in the case where the previous judicial bar examination has been abolished and the law school system goes into full effect, excluding the qualitative comparison of which selection process is more practical in turning out Judicial Officers, to evaluate from a strictly cost analysis point of view whether the law school system serves as a barrier of entry to any socioeconomic group. And if in fact this barrier exists, to analyze which socioeconomic group has the least chance of being able to enter. Such analysis can be seen as having significant meaning in supporting the fairness of Korea’s education system and job opportunity system and also the advancement of the Judicial Officer selection and law industry. Therefore, this study excludes any elements in the current law school entrance exam system and the previous judicial bar examination system that cannot be accurately quantified, and compares the two systems within the bounds of quantifiable ranges, such as the analysis of the total and differential costs, and also the opportunity cost of becoming a Judicial Officer. All these factors are used for comparative analysis, and to present an official set of criterion that can be used to predict the chance of a certain socioeconomic group being successfully selected as a Judicial Officer has significant meaning as a case study of cost analysis. If the law school system continues, a phenomenon in which the entry of individuals into legal circles is determined according to their economic income quantiles will set in. Therefore, various reviews on the lawyers training system should be performed. In relation to the costs of training lawyers, critics about the national judicial examination point out the seriousness of the problem of social opportunity costs due to numerous “unemployed individuals produced after failing in the examination” because the acceptance ratio remains at 3%. The costs borne by examinees who prepare for the existing national judicial examination are explicit costs that are borne by the examinees themselves. As they are willing to pay the costs, these costs can be viewed as avoidable costs. However, the costs borne by examinees for law schools are imputed costs under a system, and therefore, are more of unavoidable costs. Operating costs borne by universities to operate law schools, and scholarships and other costs borne by universities to meet the conditions required to operate law schools are indirect costs, and thus, these may be categorized as indirect opportunity costs borne by society. In addition, we should be aware that if the bar examination following the law school system continues to be operated for a long time, opportunity costs incurred by declines in the acceptance ratio should be borne. This study conducted an analysis that is limited to the analysis of costs that will actually be incurred or are projected to be incurred while excluding overall axiological judgements on the lawyers training system or discussions on the appropriateness of the system. Therefore, it should be noted that there can be a number of variations according to circumstantial changes. However, there was a limitation in the cost analysis. For example, the operating costs of law schools borne by universities and implicit social indirect costs were excluded from the analysis because it was actually impossible to obtain data on these costs or measure them.

We report a fetal therapy of two cases of type I congenital cystic adenomatoid malformation(CCAM) of the lung. The two fetuses were treated by thoracoamniotic shunting, using a basket-shaped catheter at 25 weeks' and 31 weeks' gestation, respectively. Cystic lesions of the both fetal lung were successfully decompressed after the shunt operation. Healthy babies were delivered at 41 weeks' and 38 weeks' gestation with normal Apgar score. Surgical resections of the affected lobe of the lung in the both babies were performed without complication at 1st and 7th day of birth, respectively. Shunt operation in-utero is considered as a safe and effective therapy for type I CCAM of the fetal lung.

<P>The present study examined ischemia-related changes in tyrosine kinase A (trkA) immunoreactivity and its protein content in the dentate gyrus after 5 min of transient forebrain ischemia in gerbils. One day after ischemic insult, cresyl violet-positive polymorphic cells showed ischemic degeneration. The ischemia-induced changes in trkA immunoreactivity were found in the polymorphic layer (PL) and granule cell layer (GCL) of the dentate gyrus. In the sham-operated group, trkA immunoreactivity in the dentate gyrus was very weak. From 30 min after ischemia, trkA immunoreactivity was increased in the dentate gyrus and peaked in the dentate gyrus at 12 h after ischemia-reperfusion. Thereafter, trkA immunoreactivity was decreased time-dependently after ischemia-reperfusion. Four days after ischemic insult, trkA immunoreactivity was similar to that of the sham-operated group. In addition, it was found that ischemia-related changes in trkA protein content were similar to the immunohistochemical changes. These results suggest that the chronological changes of trkA in the dentate gyrus after transient forebrain ischemia may be associated with ischemic damage in polymorphic cells of the dentate gyrus.</P>

허혈에 대한 연구는 중추신경계통에서 대부분을 차지하고 있다. 그러나 허혈은 중추신경 뿐 아니라, 말초신경에도 많은 영향을 미칠 것으로 생각된다. 특히 머리 부분에 있는 대부분 장기들의 일반감각을 담당하는 삼차신경절은 매우 중요할 것으로 생각한다. 신경전달물질의 분비와 감각의 조절 등에 중요한 칼슘결합단백질은 세포질내 칼슘을 조절하여 감각의 전달에 매우 중요하다. 따라서 본 연구는 Mongolian gerbil의 삼차신경절에서 인위적으로 허혈-재관류를 유발하여 calbindin D-28k (CB)와 calretinin (CR)의 경시적인 변화와 그 의미를 연구해 보고자 하였다. 정상군에서 CB과 CR 면역반응은 큰 크기, 중간 크기, 작은 크기의 신경세포에서 관찰되었다. 허혈-재관류 후 12시간까 지는 면역반응세포 수의 변화에 큰 차이를 관찰할 수 없었다. 허혈-재관류 후 1일 경에는 CB과 CR을 함유한 큰 신경세 포의 수가 급격하게 증가하였으며, 그 이후부터 CB 면역반응세포는 감소하였고, CR 면역반응세포는 허혈-재관류 후 4일 경에 중간 크기 신경세포가 정상군보다 3배 가량 증가하였다. 이상의 연구 결과는 허혈-재관류 후 1일 경에 큰 신경세포에서 CB와 CR 면역반응의 증가가 있었는데, 큰 신경세포들 은 A fibers를 함유하고 있으므로, 이 시기에 CB와 CR이 기계적 자극의 전도에 영향을 줄 것으로 생각이 된다. 또한 허 혈-재관류 후 4일 이후에 중간 크기의 신경세포에서 CR 면역반응 세포의 증가는 이들이 Aδ 또는 C fiber를 함유하고 있 으므로, 이 시기에는 통증이나 온도 감각에 CR이 관여할 것으로 생각된다. Many researches have focused upon temporal changes of neurotransmitters and/or neuromodulators in the central nervous system after ischemic insult. In sensory neurons, the spatial and temporal alterations of neurotransmitters have been little studied. Calbindin D-28k (CB) and calretinin (CR) have been suggested to play a role in the transmission of neurotransmitters. Therefore, in the present study we investigated the chronological alteration of CB and CR immunoreactivity in the trigeminal ganglion cells of the Mongolian gerbil after ischemic insult. In the sham operated group, CB and CR immunoreactivities were found in small-, medium- and large-sized neurons. One and two days after ischemia-reperfusion, small and large-sized CB immunoreactive neurons increased significantly. Thereafter, number of the CB immunoreactive neurons decreased markedly. Furthermore, five days after ischemia-reperfusion, CB immunoreactivity was detected in a few neurons, and its immunoreactivity was also very weak in the cytoplasm. Number of the large-sized CR immunoreactive neurons increased significantly one day after ischemia-reperfusion. Thereafter, the number of the large-sized CR immunoreactive neurons decreased. Especially, the number of the medium-sized CR immunoreactive neurons increased dramatically 4 days after ischemia-reperfusion. These results suggest that an increase of CB and CR may play an important role in modulating the mechanoception 1 day after ischemia-reperfusion, because the immunoreactivities increased in large-sized neurons which have the myenlinated A fibers. These results also suggest that significant increase of CR expression in medium-sized neurons 4 and 5 days after ischemia-reperfusion may provoke CR in modulating the nociception or thermoception because the medium-sized neurons which have the myenlinated Aδ or C-fibers.

The purpose of this study was to investigate the biomechanical, histologic findings of distracted regenerate and TMJ response in modified distraction osteogenesis (DO) technique combined with compression force as biomechanical stimulation method which has been suggested in 2002, and developed thereafter by authors. This study was performed with two experiments. First experiment was designed to explore the optimal ratio of compression force versus distraction force for the new DO technique. Second experiment was planned to evaluate the reaction of TMJ tissue, especially condyle, disc after application of the DO technique with compression force. Total 52 New Zealand adult male-rabbits with 3.0kg body weight were used for the study. For the first study, 30 adult male-rabbits underwent osteotomy at one side of mandibular body and a external distraction device was applied on each rabbit with same manner. In the control group of 10 rabbits, final 8 mm of distraction with 1 mm rate per day was done with conventional DO technique after 5 latency days. For the experimental group of 20 rabbits, a compression force with 1 mm rate per day was added to the distracted mandible on 3-latency day after over-distraction (over-lengthening). As the amount of the rate of compression versus distraction, experimental subgroup I (10 rabbits) was set up as 2 mm compression versus 10 mm distraction (1/5) and experimental subgroup II (10 rabbits) was set up as 3 mm compression versus 11 mm distraction (about 1/3). All 30 rabbits were set up to obtain final 8 mm distraction and sacrificed on postoperative 55 day to analysis on biomechanical, and histologic findings of the bone regenerates. For second study, 22 adult male-rabbits were used to evaluate TMJ response after the DO method application with compression force. In the control group, 10 rabbits was used to be performed with conventional DO method, on the other hand, in a experimental group of 10 rabbits, 10 mm distraction with 2 mm compression (1/5 ratio) was done. The remaining 2 rabbits served as the normal control group. Histomorphologic examinations on both condyle, histological studies on condyle, disc were done at 1, 2, 3, 4, 7 weeks after distraction force application. The results were as follows: 1. On the bone density findings, the experimental group II (force ratio - 1/3) showed higher bone density than the other experimental group (force ratio - 1/5) and control group (control group - $0,2906\;g/cm^2$, experimental group I - $0.2961\;g/cm^2$, experimental group II - $0.3328\;g/cm^2$). 2. In the histologic findings, more rapid bone maturation like as wide lamellar bone site, more trabeculae formation was observed in two experimental groups compared to the conventional DO control group. 3. In morphologic findings of condyle, there were no differences of size and architecture in the condyle in the control and experimental groups. 4. In histologic findings of condyles, there were thicker fiberous and proliferative layers in experimental group than those of control group until 2 weeks after distraction with compression force. But, no differences were seen between two groups on 3, 4, 7 weeks after compression. 5. In histologic findings of disc, more collagen contents in extracellular matrix, more regular fiber bundles, and less elastin fibers were seen in experimental group than control group until 2 weeks after distraction with compression. But, no differences were seen between two groups on 3, 4, 7 weeks after distraction with compression. From this study, we could identify that the new distraction osteogenesis technique with compression stimulation might improve the quality of bone regeneration. The no remarkable differences on TMJ response between control and experimental groups were seen and TMJ tissues were recovered similarly to normal TMJ condition after 3 weeks.

<P><B>Abstract</B></P><P>It is known that the hippocampus has vital functions in learning and memory, behavioral regulation, and activity-dependent synaptic plasticity, and that the hippocampus contains high levels of brain-derived neurotrophic factor (BDNF). In the present study, we followed age-dependent changes of BDNF immunoreactivity and protein level in the gerbil hippocampus to identify the correlation between BDNF and aging. BDNF immunoreactivity and its protein level significantly increased at postnatal month (PM) 12 in the hippocampus and thereafter reduced. At PM 24, BDNF immunoreactivity in the hippocampal CA1 region and dentate gyrus was similar to that in the PM 1 group, whereas BDNF immunoreactivity in the CA2/3 region at PM 24 was higher than that at PM 1. In the PM 24 group, an age-related neuronal loss and the decrease of reference and working memory were observed. In conclusion, our results suggest that observed reduction in BDNF and reference memory may be associated with age-dependent neuronal loss in the hippocampal CA1 region.</P>

Hur, Sang-Woo,Kim, Shin-Kwon,Kim, Dae-Jung,Lee, Bae-Ik,Park, Su-Jin,Hwang, Hyung-Gyu,Jun, Je-Cheon,Myeong, Jeong-In,Lee, Chi-Hoon,Lee, Young-Don The Korean Society of Developmental Biology 2016 발생과 생식 Vol.20 No.3

In this study, we investigated the characteristics of CCK-producing cells and mucus-secreting goblet cells with respect to stomach fish and stomachless fish of the Gobiidae in order to provide a basis for understanding the digestive physiology. Hairychin goby (Sagamia geneionema), which is stomachless fish, the numbers of mucus-secreting goblet cells is highest in the posterior intestine portion (P<0.05), while CCK-producing cells are scattered throughout the intestine. Gluttonous goby (Chasmichthys gulosus), which is stomach fish, mucus-secreting goblet cells are most abundant in the mid intestine portion (P<0.05), whereas CCK-producing cells are observed only in the anterior and mid intestine portion. Trident goby (Tridentiger obscurus) which is stomach fish, mucus-secreting goblet cells were most abundant in the mid intestine portion (P<0.05). CCK-producing cells are found in the anterior and mid intestine portion. Giurine goby, Rhinogobius giurinus which is also stomach fish, the largest number of mucus-secreting goblet cells showed in anterior intestine portion except for esophagus (P<0.05). CCK-producing cells are present only in the anterior and mid intestine portion. In S. geneionema, digestive action occurs in the posterior intestine portion to protect and functions to activate digestion. In contrast, in C. gulosus, T. obscurus and R. giurinus, their digestive action occurs in the anterior and mid intestine portion to protect and functions to activate digestion. Further studies of the modes of food ingestion by these fish, the contents of their digestive tracts, and the staining characteristics of the goblet cells need to be carried out.

Berberry Extract Reduces Neuronal Damage and <i>N</i>-Methyl-<small>D</small>-aspartate Receptor 1 Immunoreactivity in the Gerbil Hippocampus after Transient Forebrain Ischemia

Yoo, Ki-Yeon,Hwang, In Koo,Lim, Beong Ou,Kang, Tae-Cheon,Kim, Dong-Woo,Kim, Sang Moo,Lee, Hyeon Yong,Kim, Jong Dai,Won, Moo Ho Pharmaceutical Society of Japan 2006 BIOLOGICAL & PHARMACEUTICAL BULLETIN Vol.29 No.4

<P>In the present study, we studied the neuroprotective effects of berberry extract (BE) against ischemic damage and the temporal and spatial alterations of <I>N</I>-methyl-<SMALL>D</SMALL>-aspartate receptor type 1 (NR1) and NR2A/2B immunoreactivities in the gerbil hippocampal CA1 region after transient ischemia to examine anti-ischemic effects and its role in transient forebrain ischemia. In the vehicle-treated group, the percentage of cresyl violet positive pyramidal cells in the CA1 region was about 11.4% compared to the sham-operated group 4 d after ischemic insult. BE showed neuroprotective effects against ischemic damage after ischemia-reperfusion. In the BE-treated groups, about 60—75% of CA1 pyramidal cells were stained with cresyl violet 4 d after ischemic insult. We observed the percentage of berberine (7.45+0.85 mg/g in BE) by HPLC, which is active ingredient of BE. NR1 immunoreactivity in the stratum pyramidale of the CA1 region in the vehicle-treated group was significantly increased at 30 min after transient forebrain ischemia, while at this time the NR1 immunoreactivity in the BE-treated groups was significantly low compared to the vehicle-treated group. The pattern of NR2A/B immunoreactivity in the stratum pyramidale of the BE-treated group and its protein levels were similar to that in the vehicle-treated group after ischemic insult. These results suggest that BE has potent neuroprotective effects against ischemic damage <I>via</I> the reduction of NR1 activity.</P>

High-temperature in situ crystallographic observation of reversible gas sorption in impermeable organic cages

<P><B>Significance</B></P><P>Crystallographic observation of adsorbed gas molecules at high temperatures is a highly challenging task due to their rapid motion. We provide evidence of restrained motions in a self-assembled organic crystal with small isolated cages, inside which the confined CO<SUB>2</SUB> molecules can be identified with in situ X-ray diffraction technique at the high temperature. Although the crystal is nonporous, the CO<SUB>2</SUB> molecules can permeate into the crystal because of thermally activated transient pathways between the cages. We show that the flexible nature of the transient pathways leads to the temperature-driven reversible CO<SUB>2</SUB> sorption, understanding of which can contribute to the design of a system with controlled capture/release of gas molecules.</P><P>Crystallographic observation of adsorbed gas molecules is a highly difficult task due to their rapid motion. Here, we report the in situ single-crystal and synchrotron powder X-ray observations of reversible CO<SUB>2</SUB> sorption processes in an apparently nonporous organic crystal under varying pressures at high temperatures. The host material is formed by hydrogen bond network between 1,3,5-tris-(4-carboxyphenyl)benzene (H<SUB>3</SUB>BTB) and <I>N,N</I>-dimethylformamide (DMF) and by π–π stacking between the H<SUB>3</SUB>BTB moieties. The material can be viewed as a well-ordered array of cages, which are tight packed with each other so that the cages are inaccessible from outside. Thus, the host is practically nonporous. Despite the absence of permanent pathways connecting the empty cages, they are permeable to CO<SUB>2</SUB> at high temperatures due to thermally activated molecular gating, and the weakly confined CO<SUB>2</SUB> molecules in the cages allow direct detection by in situ single-crystal X-ray diffraction at 323 K. Variable-temperature in situ synchrotron powder X-ray diffraction studies also show that the CO<SUB>2</SUB> sorption is reversible and driven by temperature increase. Solid-state magic angle spinning NMR defines the interactions of CO<SUB>2</SUB> with the organic framework and dynamic motion of CO<SUB>2</SUB> in cages. The reversible sorption is attributed to the dynamic motion of the DMF molecules combined with the axial motions/angular fluctuations of CO<SUB>2</SUB> (a series of transient opening/closing of compartments enabling CO<SUB>2</SUB> molecule passage), as revealed from NMR and simulations. This temperature-driven transient molecular gating can store gaseous molecules in ordered arrays toward unique collective properties and release them for ready use.</P>
