Feed safety is needed to produce and provide safe animal feeds for consumers, animals, and the environment. Although feed safety regulations have been set for each country, there is a lack of clear feed safety regulations for each livestock. Feed safety regulations are mainly focused on heavy metals, mycotoxins, and pesticides. Each country has different safe levels of hazardous materials in diets. Safe levels of hazardous materials in diets are mostly set for mixed diets of general livestock. Although there is a difference in the metabolism of toxic materials among animals, the safe level of feed is not specific for individual animals. Therefore, standardized animal testing methods and toxicity studies for each animal are needed to determine the correct safe and toxic levels of hazardous materials in diets. If this goal is achieved, it will be possible to improve livestock productivity, health, and product safety by establishing appropriate feed safety regulations. It will also provide an opportunity to secure consumer confidence in feed and livestock products. Therefore, it is necessary to establish a scientific feed safety evaluation system suitable for each country's environment. The chance of outbreaks of new hazardous materials is increasing. Thus, to set up appropriate toxic levels or safe levels in feed, various toxicity methods have been used to determine toxic levels of hazardous materials for humans and animals. Appropriate toxic testing methods should be developed and used to accurately set up and identify toxicity and safe levels in food and feed.

Every country finds a way to respond a lot of terrors to keep her safe in many ways. Our country, before a terror outbreaks, makes various countermeasures such as strengthening international cooperative systems, strengthening informational ability to countermeasure terror, restricting for terrorists to enter or exit from our country, restricting other countries to input weapons in our country to prevent from terror in the aspect of precaution. A terror is more grave than any other one in behavior, and the criminals have to be punished so much and be discriminated from other ones, too. So, a concept of general crime and terror has to be defined. It is finished in the academic area to some extent, but, it is not sufficient in lawful area so much. Afterwards, it is necessary to establish counter-terror protection laws regulating terror crimes directly. In addition, it is necessary to define concretely and clearly the terror activity and deduce the definition of terrorism.

Elimination of dangerous points is the most effective method for safety in mechanical equipments. The next effective method is recognized as isolation and/or safe-guarding of dangerous spots from human beings. With progress of mechanical automation technique such as industrial robots, the need for safe-guard-ins is now being enlarged. It is needless to say that when a machine-guard is designed and installed, a comprechensive understanding of human movement is indispensable. But in this country, there is no scientific for those thems, and no one verifield whether it is valid to apply general guideline such as OSHA's to Korean or not. Further, basic anthropometric items for safety reach standards are neither availble nor included in nation-wide anthropometry project. In this research, human anthropometry data of Korean youngsters are analyzed for safety barrier and safety slit width, and compared with guidelines of other countries-Germany, United Kingdom, Japan, and USA. Though they are standards for safety, since they are based upon their own peoples' data, some of them especially foot reach are not not applicable in this country. It should be notified that careful application of numeric value is very important.

It is no doubt that information technology is the key factor of national safety. Information technology is positively useful for national security such as crime prevention and detection, criminal investigation, disaster management, and national defense. However, it might be a threat to the security as we saw in the examples such as '3.4 DDoS attacks' and 'Nong-hyup Computer Network Failure.' Although the effect that information technology makes upon the national security is immense, the current legal system does not reflect these changes well. National security should be kept during 'prevention-response-recovery' process regardless it is in the online on offline. In addition, public administration for national security should be based on laws. However, the current legal system is lack of legislative basis on cyber and physical disaster, and the laws on the response to disaster might cause confusing. Therefore, this study examines the limitation of the current legal system on national security, and suggests directions for the development of the system based on the new establishment of the legal concept for 'national security'.

Korea has been recognized as a safe country about the substance abuse, but now is not safe country because there are over 10 thousand drug related offenses in a year since 1999. Seventy percent of them are drug abusers, so Korea government must have stronger political strategies about the prevention and the treatment of the drug abuse. Till now Korea government has focused on the imprisonment rather than the treatment for the drug abusers. So the relapse rates are over 40% among the incarcerated drug abusers. Now we need more treatment strategies and development of treatment methods to decrease the relapse rates. Substance abuse is a brain disease with a chronic relapsing nature and has a bio-psycho-social etiology. So treatment process has three steps, motivation enhancement treatment for substance-free lifestyle, rehabilitation aimed at maximizing multiple aspects of life functioning, and relapse prevention. To improving the treatment strategies the Government must execute the national survey about the substance abuse, enforce a law to operate the drug court and to sentence a treatment order with a probation, and establish a national addiction institute for study and education about the substance abuse.

In Korea there is still no basic standard for organic agriculture and organic farmers in Korea do not follow the minimum requirements of IFOAM basic standard Most of them just practice the organic agriculture applying organic fertilizer, commercial seed without legume, rotation and green manure. But they believe this system is a absolutely environmental friendly agricultural system and it produce a safe agricultural product since they are not aware of the basic standard of organic agriculture at all. The overuse of organic fertilizer by some organic farmer have caused some severe problems risk for nitrate and phosphate leaching. In soil profile showed the potential risk for nitrate and phosphate leaching. In the paper, it is discussed on the environmental friendly function and the safe vegetable production by european organic agriculture which keeps the internationally recognized basic standards of organic agriculture. Therefore it is strongly recommended that korean organic farmer have to follow the IFOAM it is strongly in order to practice the environmental agriculture and produce the safe food. And it is also necessary to introduce to Korea the basic standard of organic agriculture which coincides with IFOAM's and Codex of FAO/WHO immediately if they really want to practice an organic agriculture in the country.

Purpose: Early diagnosis of gastric cancer is still the exception in Western countries. In the East, as in Japan and Korea, this disease is an endemic disorder. More conservative surgical procedures are frequently performed in early gastric cancer cases in these countries where sentinel lymph node navigation surgery is becoming a safe option for some patients. This study aims to evaluate preliminary outcomes of patients with early gastric cancer who underwent sentinel node navigation surgeries in Brazil, a country with non-endemic gastric cancer levels. Materials and Methods: From September 2008 to March 2014, 14 out of 205 gastric cancer patients underwent sentinel lymph node navigation surgeries, which were performed using intraoperative, endoscopic, and peritumoral injection of patent blue dye. Results: Antrectomies with Billroth I gastroduodenostomies were performed in seven patients with distal tumors. The other seven patients underwent wedge resections. Sentinel basin resections were performed in four patients, and lymphadenectomies were extended to stations 7, 8, and 9 in the other 10. Two patients received false-negative results from sentinel node biopsies, and one of those patients had micrometastasis. There was one postoperative death from liver failure in a cirrhotic patient. Another cirrhotic patient died after two years without recurrence of gastric cancer, also from liver failure. All other patients were followed-up for 13 to 79 months with no evidence of recurrence. Conclusions: Sentinel lymph node navigation surgery appears to be a safe procedure in a country with non-endemic levels of gastric cancer.
