Recently the increase of natural disaster and man-made disaster, newly emerging infectious diseases and bioterrorism attack changed the world in many aspects. So the Ministry of Health and Welfare and other related agencies are trying to solve the problems with disasters. We discussed these problems in the following eleven categories. (1) emergency medicine (2) communicable disease control, (3) food safety control, (4) public facilities safety, (5) social welfare facilities safety, (6) bioterrorism control, (7) geriatric health care, (8) insurance support, (9) overseas disaster victim support, (10) national organization protection, (11) fire fighter safety in forest fire. Through the reviews on the various kinds of disaster, we proposed the disaster control measure for the near future.

This study aims (1) to identify whether real terms of imprisonment for sexual offenders against children are different between the first trial and appeal trial in 16 cases and (2) to assess which sentencing factors such as history of sexual crime of perpetrator, forgiveness of children, regretfulness of perpetrator, power of perpetrator, and relationship of perpetrator and victim influence sentencing period of imprisonment in the first and appeal trials, respectively. This study used cases which were prosecuted for sexual crimes against children since the protection act on the children and juveniles from sexual abuse was enacted in 2000. The target cases of the study include 8 first trials and 8 appeal cases which were appealed to the Supreme Court between 2000 and 2015. Result condition is the real term of imprisonment. Cause conditions include sentencing factors such as history of sexual crime, regretfulness, and power of perpetrator, forgiveness of child, and relationship between offender and victim. We employed Qualitative Comparative Analysis (QCA) for data analysis. We found that there are sentences in the first trial with lower terms than appeal trial regarding child sexual crimes. In addition, we found that (1) power of perpetrator and forgiveness of victim significantly influenced sentencing periods of imprisonment at levels of courts; (2) cause condition considered as comparatively more important in the first trial was regretfulness of perpetrator(but not in the appeal trial); and (3) relationship of perpetrator and child was not important in sentencing for sexual crime at both levels of trials.

Theoretical modelling and computational results for frequency coordination are presented over mobile base station and fixed wireless systems in urban or sub-urban area. Computational results with key parameters needed for interference analysis are performed and discussed in terms of system characteristics, propagation model, protection ratio, frequency dependent rejection, and discrimination angle with signal-interference plane. Based upon minimum coupling loss methodology, calculated interference powers of victim receiver for assumed system parameters are compared with maximum allowable interference power derived from protection ratio as functions of discrimination angle and distance including height-gain model in urban or sub-urban area. The proposed method is applicable for technical analysis on co-existence or interoperability for the various wireless systems, mandatory for frequency coordination or reallocation process.

In the rapidly changing current society, the Korean National Police(KNP) is facing a lot of demands from the citizens like the protection of subject/victim rights, independence of investigation authority, disclosure of actual truth, and prevention & eradication of crimes. It is widely recognized among the Korean people and the police that the KNP is always standing for the rights of the people and it is high time that the KNP should be restored as the pioneer for the protection of human right. In this situation, the tremendous emphasis is given on the importance of investment in investigative training through the long-term master-plan in order to renovate its constitution, to level up its quality, and to cope with the highly sophisticated crime patterns. Korean police have already shown its outstanding investigative skills of identification of the deceased throughout large cases like Daegu subway arson and tsunami in Southeast Asia. In addition, the skills of cyber crime investigation are highly recognized by foreign law enforcement agencies. However, the investigative skills and abilities are being degraded and the morale of the investigative personnel are falling due to the insufficiently of the finite training budget. Lack of financial support results in the lack of training program and poor training environment, which subsequently leads to the inefficiency of training. Additionally, no long-term budget for fostering specialized investigative agents is allotted. Considering the fact that more than 95% of crimes in Korea are being primarily investigated by the Korean police, we have to understand the importance of the police. By the tremendous investment in investigative training which can lead to the high-quality investigations, the Korean police can ultimately contribute to the protection of safety and life of its people.

If an external attacker takes from a victim's smartphone a copy of a secret application or an application to which fingerprinting technique is applied, secret information can be leaked or the legitimate user can be misunderstood as an illegal redistributor, which results in a serious security problem. To solve this problem, this paper proposes an Android application code protection scheme using fingerprint authentication and dynamic loading. The proposed scheme divides one application into CLR(Class LoadeR) and SED(SEperated Dex). CLR is an APK file with the ability to dynamically load the SED, and the SED is a file containing the classes required to run the application. The SED is stored inside the smartphone after being encrypted, and the SED can be decrypted only if the user is successfully authenticated using his or her fingerprint. The proposed scheme can protect the application code from the attacker who physically acquired user's smartphone.

This paper analyzed interference impact between wireless headset and Wireless Fidelity which get a high possibility of simultaneously operating in the Industry Science Medical(ISM) bands. Analysis methods of Minimum Coupling Loss(MCL) and Monte Carlo(MC) were applied by using the characters and parameters referenced to Institute of Electrical and Electronic Engineers(IEEE) 802.11b. The protection distance between interferer (WiFi transmitter) and victim (Wireless headset receiver) was calculated through the MCL. The protection distance was obtained for the case of single interferer, and the maximum allowable number of multiple interferers was computed according to the cell radius of a victim system to meet 5 % below of interference probability by using a statistical analysis based on the MC method. The analysis results are expected to be used as a guideline to coexist the wireless headset and low power devices in the ISM band.

This is a study on the art style of amimal fight in Scytian ornaments which had been popular in Steppe region of Eurasia. Animals were considered to have magical power and to provide protection against evil or disaster and representations of them thus occupied an important place in life. This style reflected the mythology, the ethical and aesthetic ideals of the warrior-nomad. With a magnificent understanding of composition and the essential nature of the material, craftsmen fashioned utilitarian objects in animal form: weaponry, horse trappings, clothes, ornaments and jewellery and other everyday objects were all decorated with zoomorphic motifs. Without copying nature, they accurately conveyed the essence of every beast depicted. The highly stylized modelling uses bold accentuated planes, while distinctive features associated with particular species are emphasized and exaggerated. The purpose and meaning of the animal motifs used in Scythian ornaments appears that in some cases the work was intended to be purely ornamental, while many times the motifs had symbolic meaning (such as the successful dominance of the aggressor over the victim portrayed in the attack scenes). Magical use of symbols may have been intended to guarantee the power of the aggressor.

Exceptive clause of ambulance stated in Road Traffic Laws of ambulance car accidents is not properly applied and emergency staffs who transfer over 85% of emergency cases are to be forced to start out to the emergency field with unstable conditions which they may be punished on the criminal and civil laws. Hereby this study makes the following suggestions to activate the duties of transferring emergency cases by emergency staffs, promote their morale and diminish the victim of emergency staffs due to traffic accidents. 1) It is prescribed that ambulance car drivers should be protected legally by applying the exceptive clauses thoroughly regulated in special case clauses because ambulance cars are used for the purpose of saving the human life. 2) On the traffic accidents occurred during the transfer of emergency cases, the special insurance system is created for treating the ambulance car accidents, not to bind the emergency staff's mistake to traffic law and the victims are compensated by the nation on the basis of insurance system and emergency staffs have the systematic security. 3) On the road over six lanes, emergency lane is set on the center and ambulance car should be used as the exclusive lane. 4) Ambulance car drivers must have the habit of transferring emergency cases rapidly within the range of legal operation.

This paper proposes a systematic design for a precoding codebook for a transmit-ing space-division multiple access (TN-SDMA) sharing spectrum with existing fixed wireless service (FWS). Based on an estimated direction angle of a victim FWS system, an interfering transmitter adaptively constructs a codebook, forming a transmit in the direction angle, while satisfying orthogonal beamforming constraints. Sum throughput results indicate that the throughput loss of TN-SDMA relative to a practical SDMA, called per user unitary and rate control ($PU^2RC$), is lower at larger number of transmission antennas, lower signal-to-noise ratio, or a smaller number of users. In particular, a small loss (12% throughput loss) is provided for practical system parameters. Spectrum sharing results confirm that TNSDMA efficiently shares spectrum with FWS systems by reducing protection distance to more than 66 %. Although a TN-SDMA system always has lower throughput compared to $PU^2RC$ in non-coexistence scenarios; it offers an intriguing opportunity to re-use a spectrum already allocated to an FWS.

Theoretical modelling and computational results for frequency coordination are presented based upon minimum coupling loss regarding the same or different wireless systems. Essential parameters involved in frequency coordination are discussed in view of system characteristics, propagation model, availability and protection ratio, frequency dependent rejection or adjacent channel interference ratio, discrimination angle, and its computational results are also evaluated. To illustrate frequency coordination procedure, received interference power between fixed wireless system of victim and mobile base station of interferer are analyzed in urban or sub-urban area and also compared with maximum allowable interference power as functions of discrimination angle and distance for assumed system parameters. The proposed method will play a practical role in technical analysis on co-existence or interoperability for the various wireless systems needed for frequency coordination.
