The zebrafish (Danio rerio) is now the pre-eminent vertebrate model system for clarification of the roles of specific genes and signaling pathways in development. I will talk about positional cloning of two developmental mutants in zebrafish. The first mutant is headless: The vertebrate organizer can induce a complete body axis when transplanted to the ventral side of a host embryo by virtue of its distinct head and trunk inducing properties. Wingless/Wntantagonists secreted by the organizer have been identified as head inducers. Their ectopic expression can promote head formation, whereas ectopic activation of Wnt signalling during early gastrulation blocks head formation. These observations suggest that the ability of head inducers to inhibit Wntsignalling during formation of anterior structures is what distinguishes them from trunk inducers that permit the operation of posteriorizing Wnt signals. I describe the zebrafish headless (hdl) mutant and show that its severe head defects are due to a mutation in T-cell factor-3 (Tcf3), a member of the Tcf/Lef family. Loss of Tcf3 function in the hdl mutant reveals that hdl represses Wnt target genes. I provide genetic evidence that a component of the Wntsignalling pathway is essential in vertebrate head formation and patterning. Second mutant is mind bomb: Lateral inhibition, mediated by Notch signaling, leads to the selection of cells that are permitted to become neurons within domains defined by proneuralgene expression. Reduced lateral inhibition in zebrafish mib mutant embryos permits too many neural progenitors to differentiate as neurons. Positional cloning of mib revealed that it is a gene in the Notch pathway that encodes a RING ubiquitin ligase. Mib interacts with the intracellular domain of Delta to promote its ubiquitylation and internalization. Cell transplantation studies suggest that mib function is essential in the signaling cell for efficient activation of Notch in neighboring cells. (중략)

The operation of a five day workweek seems to be increased continuously, Many city-workers will make good use of their spare time and search after a lot of devices that can seek for the maximum value of leisure utility. The demand of potential customers that want to enjoy weekend in farming villages is coming out greatly. That is, the condition of users that will travel the farming villages is getting better. But the actual states of farming villages are not ready in many parts yet. Therefore we must activate the tourist attraction in farming villages that can be satisfied the city-workers' expectation. And after making the sightseeing environment infrastructure, we must develop the programs intimate with environment, improve the sightseeing agricultural management and consolidate various systems as soon as possible. So in this study, after investigating the demand preference degree of city-workers, I tried to grope an activation plan with the base which will reach. Being more urgent what more, not the simple sightseeing agriculture that the farming experience was the focus of, but it is very important to develop the program of environment sightseeing agriculture. It will lay the stress on playing and education culture which city-workers can enjoy and experience. And with constructing the base facility like a city form, we must develop cheap and various goods and the execution of modernized weekend farms. For this, first the consciousness conversion against the customer management of farmers must precede and the change of government policy and the support polity is important. I hope that this study with the five-day workweek has the chance to contribute in the economic growth of farming villages and efficient use and management of the natural environment resources through the activation of sightseeing agriculture.

Activation Plan for International Health Care through the Resolution of Medical Disputes with Foreign Patients. The field of international health care is currently being expanded and developed into the new industrial field of medical tourism through the convergence of medicine - a public sector - and tourism - a private sector. This study examines problems with medical law regarding the prevention of medical disputes that may occur when attracting foreign patients and the resolution of these disputes. It also introduces the current most ideal resolution plan for medical disputes. Advanced measures for the prevention of medical disputes with foreign patients are as follows: First, when conducting international health care, the obligation to explain a medical treatment should be applied at higher standards for foreign patients. Second, all medical treatment procedures, including appointments, treatments, discharge, post-operation consultations, and follow-up treatments of foreign patients should be charted and recorded. A checklist regarding precautions for each procedure along with a response manual for problems should also be established. These regulations can prevent unexpected conflicts in advance when medical disputes occur. If a medical dispute with a foreign patient occurs despite thorough advance prevention, it can be resolved through reconciliation, mediation, and arbitration. The government and the medical field along with its related industries and authorities should put their efforts into developing these priori/posteriori measures for the activation of international medical health care. The laws and technological/human capabilities in medicine should also be improved in order to activate international medical health care.

This study aimed at figuring out the current state of 26 family-health support centers in Gyeonggi-do, in order to prepare an activation plan for the centers. These centers are the main mediators of the family health operation. This study also aimed to understand the center users' satisfaction and demands. The results were as follows. First, a total of 65,794 participants from 9,960 businesses were processed. The majority had attended various integrated family services, followed by family counseling and/or family-friendly culture-establishing businesses. Second, the main users' profiles were as follows: average age, 41; average number of persons in the family, 3.78; education above foundation-level degree; diverse jobs that included special occupations; average monthly incomes of 3,390,000 won; and a middle-class living standard (as self-described by participants). Third, the users' main concern for their families was "financial difficulties," and they had an interest in education and counseling. Although they thought education and counseling were suitable solutions, they hesitated because they did not think their problems were serious enough to merit them. Fourth, the satisfaction level of their participation in their center's program was generally high, at 3.9-4.2 points. The majority of them said they would attend again in the future.

This study suggests a plan to expand the rural experience program linked to natural disaster through the case analysis of the village of Garisan-ri, Inje-gun, Gangwon-do, Republic of Korea. This will help to establish the necessary improving and policies for Re-leap of rural villages in disaster areas and activation of rural experience villages. The local residents have created flood recovery stories, disaster response content, and disaster prevention camp sites, all of which have been hit by serious disaster damage. It has also contributed to the revitalization of the village by providing various experience programs such as disaster response training, crossing rapids, and evacuation experience. This is a way to get rid of the negative perception of disaster and utilize it. The conversion of idea through disaster experience content contributed to the activation of the area. By linking the disaster experience contents to the rural experience program in the future, it can be helpful to avoid the duplication of contents and limit the similar operation method, which is an existing problem of rural experience villages.

To explore the role of histone deactylase (HDAC) activation in an in vivo model of hypertrophy, we studied the effects of Trichostatin A (TSA). TSA subjected to thoracic aortic banding (TAB)-induced pressure stress in mice. In histological observations, TAB in treated mice showed a significant hypertrophic response, whereas the sham operation remained nearly normal structure with partially blunted hypertrophy. TSA treatment had no effect (measured as HW/BW) on sham-operated animals. TAB animals treated with vehicle manifested a robust ~50% hypertrophic response (p<0.05 vs sham). TAB mice treated with 2 mg/kg/day TSA manifested a blunted growth responses, which was significantly diminished (p<0.05) compared with vehicle-treated TAB mice. TAB mice treated with a lower dose of TSA (0.5 mg/kg/day) manifested a similar blunting of hypertrophic growth (~25% increase in heart mass). Furthermore, to determine activity duration of TSA in vitro, 1 nM TSA was added to H9c2 cells. Histone acetylation was initiated at 4 hr after treatment, and it was peak up to 18 hr, then followed by significantly reduced to 30 hr. We also analyzed the expression of p53 following TSA treatment, wherein p53 expression was elevated at 4 hr, and it was maintained to 24 hr after treatment. ERK was activated at 8 hr, and maintained till 30 hr after treatment suggesting an intracellular signaling interaction between TSA and p53 expression Taken together, it is suggested that HDAC activation is required for pressure-overload growth of the heart. Eventually, these data suggest that histone acetylation may be a novel target for therapeutic intervention in pressure-overloaded cardiac hypertrophy.

Recently, Thin film transistors (TFTs) with amorphous oxide semiconductors (AOSs) can offer an important aspect for next generation displays with high mobility. Several oxide semiconductor such as ZnO, $SnO_2$ and InGaZnO have been extensively researched. Especially, as a well-known binary metal oxide, tin oxide ($SnO_2$), usually acts as n-type semiconductor with a wide band gap of 3.6eV. Over the past several decades intensive research activities have been conducted on $SnO_2$ in the bulk, thin film and nanostructure forms due to its interesting electrical properties making it a promising material for applications in solar cells, flat panel displays, and light emitting devices. But, its application to the active channel of TFTs have been limited due to the difficulties in controlling the electron density and n-type of operation with depletion mode. In this study, we fabricated staggered bottom-gate structure $SnO_2$-TFTs and patterned channel layer used a shadow mask. Then we compare to the performance intrinsic $SnO_2$-TFTs and doping hafnium $SnO_2$-TFTs. As a result, we suggest that can be control the defect formation of $SnO_2$-TFTs by doping hafnium. The hafnium element into the $SnO_2$ thin-films maybe acts to control the carrier concentration by suppressing carrier generation via oxygen vacancy formation. Furthermore, it can be also control the mobility. And bias stability of $SnO_2$-TFTs is improvement using doping hafnium. Enhancement of device stability was attributed to the reduced defect in channel layer or interface. In order to verify this effect, we employed to measure activation energy that can be explained by the thermal activation process of the subthreshold drain current.
