With the purpose of preventing improper development on the national land, the land development permission system which is performed from 2002 has meaning as a type of limiting the property right, but modification on the details of traditionally understood land ownership is inevitable. Also, releasing the development prohibit on the land not only stop in recovering the freedom for land development, but also can be interpretated as a cause of forming the land development right, therefore the purpose of this study is to develop this into a real right. When we look at the development activity permission as a form of limiting the property right, constitutional problems of basis for that limit and compensation demand can occur. However, that limit can be recovered or relieved through permitting the development activity, therefore the compensation problem can be solved. Due to the development activity permission system, the land development right was separated from the land ownership to be communalized, and now, the land ownership only has condition use right left and don't have the future condition change right in principle, therefore modifying the traditional concept of land ownership is inevitable. By the virtue of the land ownership authority, the land development permission system must have the property to separate the development right as the independent right to be authorized of its legitimacy. Without these properties, the land development permission system cannot satisfy the social necessity of the land development right and its discussion under the category of the land ownership limit theory can't be deviated. In the existing "Civil Law" or in the Land Regulation Law system, there are many difficulties and limits in generalizing the land development right as a real right. Therefore, it is considered that by establishing a social law idea of Framework Act on the Land to characterize the land right theory in the real right theory, the land development permission system or the development right theory should be studied and developed independently and systematically.

The development of the biomedical science and technology has extended an argument about a status in constitutional law of unborn human life and a protection of the potential human life to that of an embryo and a gamete beyond a fetus. This argument has been focused on whether we should provide unborn or potential human life with human dignity and the right to life that are guaranteed by the constitutional law altogether or separately. If the right to life is given to unborn or potential human life, on what grounds can we restrict this right. Those who argue for the unity of the right to life with human dignity and the inseparability of those two claims that the right to life in itself should be guaranteed absolutely. According to the constitutional law, however, any constitutional right of the human person within the protection of essential part of the right can be compared with each other and restricted with some valid reasons from the legal perspective. This measure is unavoidable in reality because one right can come into conflict with another right frequently. Since fetus and embryo are in a process of developing into the human person, it is difficult to think that they are the same with the human person. For that reason, it is hard to consider that the right to life of fetus or embryo is the same with that of the human person. However, since a fetus has a special status as a potential human person, and an embryo also has a special value as a potential fetus upon an implantation, the right to life of fetus or embryo should be judged differently according to the stage of their development. A study on a constitutional status and protection of a fetus and an embryo is essential because unborn or potential human life is the origin of human person. Therefore, we have to make much account of their right to life and seek the legal respect for their inherent value.

Pharmacogenomics is the study that examines how genetic variations affect the ways in which people respond to drugs. The ways people respond to drugs are complex traits that are influenced by many different genes. Pharmacogenomics intends to develop rational means of optimizing drug therapy, with respect to the patients' genotype, to maximize efficacy with minimal adverse drug reactions. Pharmacogenomics has the potential to revolutionize the practice of medicine, and promises to usher in an area of personalized medicine, in which drugs and drug combinations are optimized for each individual's unique genetic makeup. Indeed, pharmacogenomics is exploited as an essential step for target discovery and drug development in the pharmaceutical industry. The goal of the personalized medicine is to get the right dose of the right drug to the right patient at the right time. In this article, we will review the use of pharmacogenomics in drug discovery and development.

Background and Objectives: Intense exercise (IE) induced myocardial fibrosis (MF) showed contradictory findings in human studies, making the relationship between IE and the development of MF unclear. This study aims to demonstrate exercise induced MF is associated with cardiac damage, and inflammation is essential to the development of exercise induced MF. Methods: Sprague-Dawley rats were submitted to daily 60-minutes treadmill exercise sessions at vigorous or moderate intensity, with 8-, 12-, and 16-week durations; time-matched sedentary rats served as controls. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum cardiac troponin I (cTnI) concentration. After completion of the exercise protocol rats were euthanized. Biventricular morphology, ultrastructure, and collagen deposition were then examined. Protein expression of interleukin $(IL)-1{\beta}$ and monocyte chemotactic protein (MCP)-1 was evaluated in both ventricles. Results: After IE, right but not left ventricle (LV) MF occurred. Serum cTnI levels increased and right ventricular damage was observed at the ultrastructure level in rats that were subjected to long-term IE. Leukocyte infiltration into the right ventricle (RV) rather than LV was observed after long-term IE. Long-term IE also increased protein expression of proinflammation factors including $IL-1{\beta}$ and MCP-1 in the RV. Conclusions: Right ventricular damage induced by long-term IE is pathological and the following inflammatory response is essential to the development of exercise induced MF.

For the last several decades, it has been recognized that technology is a key factor in becoming an ADC and an advanced firm. So many countries and individual firms have been increasing investments on technology development. Especially LDCs including Korea choose technology transfer and transaction as an important alternative of their own technology development. To activate technology transaction and transfer, it is necessary to establish an technology transaction system, namely a Technomart that will make good connections between technology suppliers and technology buyers, and efficient functional linkages of supporting infrastructures including organizations and laws related with technology transactions. Therefore this study reviewed both the characteristics of technology transfer and transaction and a conceptual structure of a Technomart through a literature review. And then, the study analyzed the Technomart related laws including an intellectual property right, a copyright, a patent right, and electric transaction related laws. In conclusion the study proposed the development directions of the Technomart related laws.

This study was conducted in cut rose cultivation field in Goyang to evaluate pesticide exposure of farmers and the relationship between the exposure and work environment/method for cut rose farmers. Dermal exposure was assessed with patch (thin chromatography layer paper), cotton glove by body parts during mixing and spraying works in which pyrethroid, organophosphate, carbamate pesticide were used in 4 cut rose greenhouses located in Goyang province, checking characteristics of environment/working method at the same time. Body parts assessed were as follows ; glove : hand, patch : head, neck(front/back), chest, back, shoulder(right/left), upperarm(right/left), forearm(right/left), thigh(right/left), shin(right/left). Pesticides were analyzed using gas chromatography(NPD/FID) after extracting with ethyl acetate. Exposure amount differed according to pesticide type. But after standardizing with total net weight of pesticide sprayed, there were no significant difference among pesticides. There were significant difference in exposure amount among body parts(especially exposure amount of thigh, shin were more than the others), which means exposure happen not by pesticide dispersion in air but by contact with cut rose(leaf, branch) indirectly. Walking forward during spraying made farmers more exposed than waling backward, these results means contacts with leaves/branches made exposure happen in cut rose greenhouse also. As a result, pesticide exposure in cut rose greenhouse was related with contact of leaf/branch which pesticide remained in, which made exposure pattern (especially exposure amount) differ by body parts

Although cardiac distribution of specific receptors for atrial natriuretic peptide (ANP) was mainly observed in the ventricular endocardium, the modulation of ANP receptors in relation to cardiac development is not defined. The present study was undertaken to investigate ANP receptor modulation in rat during development. In the developmental stages examined (fetus, after postnatal 3-days, 1-, 2-, 3-, 4-, and 8-week-old Sprague Dawley rats) specific ANP binding sites were localized in the right and left ventricular endo-cardia by quantitative in vitro receptor autoradiography using (equation omitted)-rat ANP as labeled ligand. The specific bindings to endocardium were much higher in the right than the left ventricle. The binding affinities of ANP were much higher in the right than the left ventricular endocardium. The difference of these binding affinities among various developmental stages was not observed in the right ventricle, whereas the binding affinity in left ventricle was gradually increased with aging and reached the peak value at 8 weeks. No significant difference in maximal binding capacities of endocardial bindings was observed in the right and left ventricular endocardia during developmental stages. Also, cGMP production via activation of particulate guanylyl cyclase-coupled receptor subtypes in the ventricular membranes was gradually decreased with close relationship to aging. Therefore, the present study show that the endocardial ANP receptor is modulated with close relationship to cardiac development in the left ventricle rather than the right ventricle, and may be involved in regulating myocardial contractility in left heart.

Using an experimental model of pulmonary hypertension, the effects of anticonstrictive drugs on the development of pulmonary vascular remodeling and right ventricular hypertrophy were studied. Male Sprague-Dawley rats weighing 200~250 gm were used. For the experimental model of pulmonary hypertension, a group of animal was given by a subcutaneous injection of monocrotaline on a dose of 20mg, 40mg, or 60mg per kg of body weight. After 4 weeks of injection, all animals were sacrificed. Another group of animal was given by a subcutaneous injection of monocrotaline in a dose of 40 mg per kg of body weight. The animals were sacrificed, in which they were kept alive for 1, 2, 3 and 4 weeks, respectively. For the effects of anticonstrictive drugs on the development of pulmonary vascular remodeling and right ventricular hypertrophy, the animals treated with monocrotaline were given daily by an intraperitoneal injection of phenoxybenzamine in a dose of 1.3mg/kg of body weight, and were given propranolol via their drinking water at a concentration of 400mg/liter. The animals were sacrificed after 4 weeks of administration. The hearts and lungs were examined histopathologically and morphometrically. The results obtained were summarized as follows: 1. The rats treated with monocrotaline showed an interstitial pneumonitis, medial thickening of the pulmonary small arteries and hypertrophy of the right ventricular wall. 2. The medial thickening of the pulmonary arteries in rats treated with monocrotaline was due to muscular hypertrophy and hyperplasia, and the right ventricular hypertrophy was due to hypertrophy of cardiac muscles. Both medial thickening of the pulmonary arteries and hypertrophy of right ventricular wall were more marked with time and with dose. 3. The daily intraperitoneal injection of phenoxybenzamine suppressed significantly the percentage medial thickness of pulmonary small arteries and the index of right ventricular hypertrophy in rats given a single subcutaneous injection of monocrotaline, but propranolol has shown no protective effect on the development of medial thickening of pulmonary arteries and right ventricular hypertrophy in treated with monocrotaline. The results described above suggested that monocrotaline is an alkaloid selectively inducing pulmonary hypertension and that a-adrenergic receptor is responsible for the pathogenesis of monocrotaline induced pulmonary hypertension in rat.
