The South Korean society has experienced many changes since the sinking of ROKS Cheonan. The government reviewed its defense posture and adopted the 5·24 Measure in its relations with North Korea. As a result, the people of South Korea became more conscious of security situations on the Korean peninsula while North Korea's economy suffered badly. Meanwhile, the South Korean government has taken a flexible stance toward North Korea in terms of exchange and cooperation since September 2011. The flexible stance was to manage inter-Korea relations in a stable manner and relieve the hardships of the North Korean people while preserving the spirits and purposes of the 5·24 Measure. The UN Security Council adopted twenty-six resolutions and statements on North Korea since June 25, 1950. They include thirteen U.N. Security Council resolutions including those concerning nuclear weapons or missile programs, nine Presidential statements, and four press statements. Resolution 82, the first U.N. resolution on North Korea, came when the Korean War broke out. Resolution 825, the first one related to nuclear or missile programs, was adopted in response to North Korea's withdrawal from the NPT. Apart from these U.N. resolutions, the United States has imposed separate sanctions against North Korea. North Korea's nuclear weapons program can be considered in comparison with that of Iran in terms of the consequences they create for the regional security. The Security Council has adopted six resolutions on Iran so far. One should note that the resolutions on Iran have had much stronger sanctions compared to those imposed on North Korea. That is, while the North Korea case may be viewed as a more serious threat to international security from the perspective of nuclear weapons development or proliferation, tougher sanctions have been placed on Iran. There are two approaches that South Korea should take in addressing the related issues. First, we should aim to reduce the gap between sanctions imposed on Iran and North Korea. It is difficult to understand that a country with more serious problems is rewarded with lighter sanctions. We should take measures through the Security Council Sanctions Committee to make individuals and groups in North Korea that play a central role in developing nuclear weapons and missiles subject to additional sanctions. Second, we have to change. Other countries in the international community have become tired of North Korea's nuclear issue and now they look to South Korea for initiative. We should correctly understand this current situation and play a leading role within our capacity. Knowingly and unknowingly, the notion that the North Korean nuclear issue may be left to South Korea has been spread around the international community. Although the situation is grave, we should try to open a new horizon in ushering in the unification era by taking the initiative with confidence that there is a looming hope ahead of us. For these tasks, we should stop thinking in the old way that has been ossified for the last two decades. We should not be pushed around by neighboring great powers in dealing with North Korea related issues anymore; we should take the initiative with resolution that we will play our role at the center of four great powers and with confidence that we can do it. Based on the confidence that the Republic of Korea has become a country with enough capacity to take the initiative, we should establish a 'National Grand Strategy' representing South Korea's strategic vision that the unification is the ultimate solution to the problems related to North Korea's nuclear weapons program.

North Korea's continuous threats and provocative behaviors have aggravated tension on the Korean peninsula particularly with the recent nuclear weapons test. South Korea's best way to cope with this situation is to maintain the balance among three policy directions: dialogue, sanctions, and deterrence. Among the three, I argue that deterrence should be prioritized. There are different sources of deterrence such as military power, economic power, and diplomatic clouts. States can build deterrence capability independently. Alternatively, they may do so through relations with other states including alliances, bilateral relations, or multilateral relations in the international community. What South Korea needs most urgently is to maintain deterrence against North Korea's local provocations through the enhancement of independent military capability particularly by addressing the asymmetric vulnerability between militaries of the South and the North. Most of all, the South Korean government should recognize the seriousness of the negative consequences that North Korea's 'Nuclear shadow strategy' would bring about for the inter-Korea relations and security situations in Northeast Asia. Based on this understanding, it should develop an 'assertive deterrence strategy' that emphasizes 'multi-purpose, multi-stage, and tailored deterrence whose main idea lies in punitive retaliation.' This deterrence strategy requires a flexible targeting policy and a variety of retaliatory measures capable of taking out all targets in North Korea. At the same time, the force structures of the army, the air force, and the navy should be improved in a way that maximizes their deterrence capability. For example, the army should work on expanding the guided missile command and the special forces command and reforming the reserve forces. The navy and the air force should increase striking capabilities including air-to-ground, ship-to-ground, and submarine-to-ground strikes to a great extent. The marine corps can enhance its deterrence capability by changing the force structure from the stationary defense-oriented one that would have to suffer some degree of troop attrition at the early stage of hostilities to the one that focuses on 'counteroffensive landing operations.' The government should continue efforts for defense reform in order to obtain these capabilities while building the 'Korean-style triad system' that consists of advanced air, ground, and surface/ subsurface weapon systems. Besides these measures, South Korea should start to acquire a minimum level of nuclear potential within the legal boundary that the international law defines. For this, South Korea should withdraw from the Nuclear Non-proliferation Treaty. Moreover, it should obtain the right to process and enrich uranium through changing the U.S.-South Korea nuclear cooperation treaty. Whether or not we should be armed with nuclear weapons should not be understood in terms of "all or nothing." We should consider an 'in-between' option as the Japanese case proves. With regard to the wartime OPCON transition, we need to re-consider the timing of the transition as an effort to demonstrate the costliness of North Korea's provocative behaviors. If impossible, South Korea should take measures to make the Strategic Alliance 2015 serve as a persisting deterrence system against North Korea. As the last point, all the following governments of South Korea should keep in mind that continuing reconciliatory efforts should always be pursued along with other security policies toward North Korea.

Toxic gases and soot deposition as a consequence of smoke inhalation can cause direct injury to the upper and lower airways and even to the lung parenchyma. A delay in proper and prompt therapy can be detrimental to critically ill burn patients with an inhalation injury. Therefore, serial chest radiography is an important diagnostic tool for pulmonary complications during treatment. The radiographic findings of the chest include normal, consolidation, interstitial and alveolar infiltrates, peribronchial thickening, atelectasis, cardiogenic and non-cardiogenic pulmonary edema, and a pneumothorax as acute complications of smoke inhalation. In addition, bronchiectasis, bronchiolitis obliterans and pulmonary fibrosis can occur as late complications. We encountered a case of 44-year-old male who presented with acute lung injury after an inhalation injury. He required endotracheal intubation and mechanical ventilation due to respiratory failure. He was managed successfully with conservative treatment. Later, a cavitary lesion of the left upper lobe was observed on the chest radiography and computed tomography, which was complicated by massive hemoptysis during the follow-up. However, the cavitary lesion disappeared spontaneously without any clinical consequences.

FREP(Fiber Reinforced Epoxy Panel) are used for strengthening the damaged RC beams due to its good tensile strength, low weight, resistance to corrosion, and easy applicability. This study sets up structure equation for FREP bending reinforcement before and during the usage of RC beam. It finds the difference and finds the mechanical characteristics of rip-off failure that is caused by stress concentration in reinforcement material cutting part to estimate the performance of bending reinforcement. The result of this research can be summarized as two main consequences. The main failure of FREP reinforced concrete beam is rip-off failure and it evaluated rip-off failure of RC reinforcing bean based on the test and analytical conditions of this study. It found that stress was concentrated due to rapid change of bending rigidity in reinforced cutting part as a result of excessive reinforcement thickness of FREP. It resulted in rip-off failure. It means that it should evaluate the rip-off failure when designing reinforcement. It analyzed the reinforcement effect according to reinforced period for FREP. It found that reinforcement effect of P-Type that was reinforced during the usage decreased compared to I-Type that was reinforced before the usage. So when reinforcing a existing structure that is being used, it should consider the stress that is produced due to the fixed load.

The purpose of this study is to find how the mother's rearing patterns and attitudes influence on a child's social personality development. Many contemporary psychologists insist that mother's rearing attitudes and methods before age of six influence on child's social personality development a great deal. Freud divided the child's developmental stages into three : oral, anal, and phallic period. According to his assumptions the way of mother's feeding and weaning has very important relationship with the personality development through ora period and how to handle toilet training will greatly influence through anal period. In addition to this, Symonds declares that a mother's rearing attitudes will influence the establishment of social characteristics of the child. The moderate attitude-not too overprotective or rejective or submissive or dominate-is desirable. If mother's attitude declines to one aspect among these four kinds too much, the child would have chances to develop maladjusted social characteristics such as aggressiveness , submissiveness, dependency, and dominativeness. The hypotheses of this study were based on Freud and Symonds theory and tested by correlation and the difference of percentage. The results of the study were as follows : I. The relationship between rearing pattern and social characteristics 1. When the child has too strictly scheduled feeding time, he will have aggressive attitudes. 2. The longer the feeding period, the more dependency the child will have. 3. In case the toilet training was taken place too early or strictly, the child will withdraw into his shell. 4. When the child failed to perform the toilet training and was punished because of that, the child's personality will likely to be too submissive or aggressive. II. The relationship between mother's attitudes and social personality 1. When the mother's attitude is too overprotective the child showed withdrawn characteristics (r = 89) or dependency ( r = 24). 2. The child whose mother has too rejective attitude also showed withdrawn characteristics ( r = 31). As Sears insisted self-demanding schedule is recommendable and the weaning supposed to be started after age of one and a half years and finished around age of two. The toilet training which has rather severe consequences than the feeding methods should be started when the child is able to understand what is expected to him. Sears says that about two years after birth would be proper but individual difference should be considered. As a conclusion, Flexible and understanding attitudes and rearing methods is necessary for a sound establishment of social personality.

The purpose of this study was to understand the management status of food wastes in school meal to find the effective ways that would reduce and recycle them. Data was collected using questionnaires from 223 school dietitians located in Jeonbuk area. The results were as followed : 1) Waste was managed by the dietitians(54.7%) and cook(42.2%). The waste disposal contract was made by dietitians(65.0%), executives(31.4%). Therefore, school dietitians had primary responsibilities in the waste management. 2) As disposal ways, 48.9% processed municipal solid waste and food waste together and 46.6% processed separately. 3) A half of schools(52.9%) produced food wastes weighed under 10$\sim$15kg daily and using food wastes as animal food for farms was most popular method to dispose(87.4%). 4) Reasons to have food-wastes were disliking the taste of menu(50.2%) and the inappropriate ways of dealing with remaining food(64.1%) and donating to food bank(33.6%) in order. 5) The suggested ways to reduce the food-waste was to improve on cooking method(72.2%), changing of portion size(61.0%), measuring the amount of leftover food(53.4%) and requesting cooperation to educators(52.9%). 6) The reported consequences of reducing the food waste were: lowered grocery expenses(46.2%), and inspiring students on helping environmental preservation(23.8%). Therefore, the administration should work on finding a method to reduce food-waste and a way to use these resources efficiently. It is important to induct student's attitude on recycling remaining products by using food bank via nutrition education. Dietitian also should consider to reduce the leftover of food by using a standardized recipe.

Although ionizing radiation (IR) has been used to treat the various human cancers, IR is cytotoxic not only to cancer cells but to the adjacent normal tissue. Since normal tissue complications are the limiting factor of cancer radiotherapy, one of the major concerns of IR therapy is to maximize the cancer cell killing and to minimize the toxic side effects on the adjacent normal tissue. As an attempt to develop a method to monitor the degree of radiation exposure to normal tissues during radiotherapy, we investigated the transcriptional responses of human peripheral blood lymphocytes (PBL) following IR using cDNA microarray chip containing 1,221 (1.2 K) known genes. Since conventional radiotherapy is delivered at about 24 h intervals at 180 to 300 cGy/day, we analyzed the transcriptional responses ex-vivo irradiated human PBL at 200 cGy for 24 h-period. We observed and report on 1) a group of genes transiently induced early after IR at 2 h, 2) of genes induced after IR at 6 h, 3) of genes induced after IR at 24 h and on 4) a group of genes whose expression patters were not changed after IR. Since Biological consequences of IR involve generation of various reactive oxygen species (ROS) and thus oxidative stress induced by the ROS is known to damage normal tissues during radiotherapy, we further tested the temporal expression profiles of genes involved in ROS modulation by RT-PCR. Specific changes of 6 antioxidant genes were identified in irradiated PBL among 9 genes tested. Our results suggest the potential of monitoring post-radiotherapy changes in temporal expression profiles of a specific set of genes as a measure of radiation effects on normal tissues. This type of approach should yield more useful information when validated in in vivo irradiated PBL from the cancer patients.

Supernumerary teeth are teeth added to the normal complement of teeth. They are most often found in the maxillary anterior region. Most supernumerary teeth in the maxillary anterior region have complications, such as impaction or malposition of permanent teeth, formation of diastema, cysts, and eruption into the nasal cavity or into the oral cavity. These complications have influence on deciding the treatment and its prognosis is depends on how these complications are treated. In clinical studies, it has been found that the removal of supernumerary teeth before the age of 5 years resulted in significant fewer eruption problems of the permanent tooth compared to removal at 7 years of age or later. However, such an early removal may leads to serious consequences of tooth development and behavioral management of patients. Therefore clinicians must consider complications of supernumerary tooth when deciding the time of removal. These cases report five-type of complication associated with supernumerary tooth such as diastema, delayed eruption, external root resorption, migration into nasal cavity and cyst formation.

Serious consequences can arise from lack of hygiene in mass catering. Microbiological testing is of value in determining hazards for developing a HACCP plan, and in demonstrating to food handlers the reality of the microbial risk. This studies was performed to describe the overall hygiene of cooking utensils and equipments, employees, and environment in mass catering establishments. Generally, hygienic conditions of cutting board and sanitized dish cloth were better than those of other cooking utensils such as knife, sieve, and peeler. It was found that the cross-contamination of knife might be caused by the use of contaminated sanitizing solution. It was observed that there was considerable variation (10$^1$~10$^{5}$ CFU) of the number of general bacteria for employee's hands. The number of general bacteria were influenced from establishment, employee, and the period of analysis. The number of Coliform group for employee's hands was in the range of 10$^2$~10$^4$CFU only at the first analysis. Total aerial bacteria in working area of mass catering establishments was below 7 CFU/Plate and aerial Staphylococcus sp. was not detected at all except one spot.
