In this two-part paper, we consider dynamic resource allocation in orthogonal frequency division multiple access(OFDMA). To reduce the reverse link overhead for channel quality information(CQI) feedback, a set of sub-carriers are tied up to a sub-channel to be used as the unit of CQI feedback, user-multiplexing and the corresponding power/rate allocation. Specifically, we focus on two sub-channel structures, either aggregated or distributed, where the SNR distribution over a sub-channel is modeled as Ricean in general, and the channel quality of a sub-channel is summarized as the mean and variance of channel gain envelop divided by noise standard deviation. Then, we develop a generalized two step channel/resource allocation algorithm, which uses the two statistical measurements, and analyze the spectral efficiency of the OFDMA system in terms of average frequency utilization. An extension to proportional fair algorithm will also be addressed. As confirmed by numerical results, the aggregated structure is preferred especially when intending aggressive link adaptation.

In Korea, the Emergency Medical Service, EMS is provided by Fire Services with 119 EMS and all the public uses the service for free. Although it appears very successful and is respected nationally, structural problem EMS exist and are worsening. First of all, the "free riding effect" becomes increasingly problematic. Some argue that 30% of the demands is not urgent or emergent. The total number of demands is increasing even without the free riding effect. The Current EMS system itself cannot meet the increasing EMS demand. The medical aspect is so poor that the EMS cannot dispatch a medical specialist to the scene. The cardiac arrest resuscitation rate is only $1.24{\sim}9.9%$, compared to 40% in Boston, MA, USA. But due to the regulations and limitations of the Fire Service organization, it is difficult to secure enough EMS resources. To work out these problems, it needs a structural innovation. To secure enough resources and achieve higher medical performance we should invite the medical sector and the private sector into EMS arena by contracting partnerships with Fire Services and charging a reasonable EMS fee. We found through statistical test that any partnership system is more effective than fire-alone system and most countries around the world have partnership system rather than fire-alone system.

During the past 5 years, domestic VoIP service has grown rapidly absorbing more than 8 million subscribers. More recently, the increase of enterprise or institutional subscribers become more dominant than individual subscribers. Supporting emergency services such as 119 in these scaled up VoIP services is very essential. In current domestic VoIP networks, the VoIP terminal's location information which are provided to the PSAP with the arriving emergency call depends on the information which are entered at the subscription time or updated by the subscribers when the terminal is moved to other place. This manual provision of location information which requires the user's intervention can result in serious failure in saving people in emergency situations, in case that users are negligent in entering the information or users enter the wrong information. In this paper, we propose an enhanced mechanism in which the terminal's location information is automatically offered by the network for emergency services in ethernet-based enterprise VoIP networks.

Purpose: This study aims to identify changes in patients' transport time and chief complaints visiting the emergency room via emergency medical services from the "pre-COVID-19 period" compared to the "COVID-19 early-stage period". Methods: This retrospective observational study analyzed the emergency medical services reports at two time periods defined by the COVID-19 virus outbreak in Korea. The study was conducted in Busan, the Republic of Korea, from January 19 through May 6, 2019. Results: The transfer time of patients transported during the "COVID-19 early-stage period" was significantly delayed compared to the "pre-COVID-19 period" (p<.05). We found a significant increase in transport time for patients complaining of respiratory infections compared to patients without symptoms (p<.05). During the "COVID-19 early-stage period", there was a significant increase in the number of patients with respiratory infections and patients complaining of general symptoms compared to the "COVID-19early-stage period" (p<.05). Conclusion: The spread of the COVID-19 virus infection delayed patient transport and increased the number of patients reporting respiratory infection symptoms. Emergency medical services will need administrative and economic support to transport the increased number of patients requiring services.

After the collapse of the Cold War, there was a shift in perception at two points in discussions on Korean unification. The real core issue of unification is first, that it is a shift in perception that the real problem of unification is not the integration of systems, but the integration of people. Second, there is a shift in perception that there are many Koreans in the four major powers related to the Korean division and their distribution is associated with the tragic history of the Korean Peninsula. The historical trauma of Korean people resulted from the oppression of the collective libido of Koreans, stemming from the pain of modern history of the Korean Peninsula. In addition, the trauma of colonization, diaspora, and division all share the structure of suppression as the '$nation{\neq}states$'. Thus, unification aims to overcome the notion that '$nation{\neq}state$' can not be separated from the process of healing the historical trauma of Koreans. First of all, this article argues that in order to achieve unification on the Korean peninsula, it requires the process of healing the traumas of colonization, diaspora, and division. Second, this paper claims that Korean unification is not only a matter of two countries, but also of making peace by healing historical trauma in Northeast Asia. Third, this paper argues that the healing of Korean's historical trauma should begin with 'sympathy' for pain and proceed to the production of a 'national commonality' through 'communication of difference', which will create a unified peninsula.

Cardiac arrest is a critical medical emergency where immediate response is essential for patient survival. This is especially true for Out-of-Hospital Cardiac Arrest (OHCA), for which the actions of emergency medical services in the early stages significantly impact outcomes. However, in Korea, a challenge arises due to a shortage of dispatcher who handle a large volume of emergency calls. In such situations, the implementation of a machine learning-based OHCA detection program can assist responders and improve patient survival rates. In this study, we address this challenge by developing a machine learning-based OHCA detection program. This program analyzes transcripts of conversations between responders and callers to identify instances of cardiac arrest. The proposed model includes an automatic transcription module for these conversations, a text-based cardiac arrest detection model, and the necessary server and client components for program deployment. Importantly, The experimental results demonstrate the model's effectiveness, achieving a performance score of 79.49% based on the F1 metric and reducing the time needed for cardiac arrest detection by 15 seconds compared to dispatcher. Despite working with a limited dataset, this research highlights the potential of a cardiac arrest detection program as a valuable tool for responders, ultimately enhancing cardiac arrest survival rates.

This study measures the efficiency of intellectual capital of Korea's banks, financial investment companies, and insurance companies using the Value Added Intellectual Coefficient (VAICTM) model, which was developed by A. Pulic and investigates into the relationship of each of VAIC's elements - efficiency of human, structural, and material capital -with business performance of the institution. we found, first, average VAIC and human capital efficiency(HCE) of Korean financial institutions during 2001 - 2012 were highest among banks, followed by insurance companies and securities firm. Secondly, in general, banks in advanced countries tend to have higher HCE and VAIC compared with the banks of developing countries. Thirdly, Korean financial institutions' HCE and VAIC are lower than those of Australia and even Taiwan and Thailand and have been on the decrease in recent years. This suggests that Korean financial institutions should enhance VAIC and HCE to build-up the international competitiveness.

This study is to suggest some developmental policies by analyzing the activities of first aid party in Kwangju and Chonnam regions for two years from Jan. 1, 1991 to the end of December, 1995. First, the residents in Kwangju and Chonnam regions have the sufficient benefits of emergency medical center, but it will be desirable that general hospital should be established and managed in Kohung peninsula which forms the wide island area far away from big cities. Second, the classification of the degree of severe case in the field by rescue members should be strengthened as the means which can reduce the number of patients transferred to the emergency room and the legal method which rescue members can select the medical agency. Third, children less than 10 are most frequent emergent patients and it is due to parent's indifference and children's in sensibility to safety. So the safely education in the course of infant and elementary education should be strengthened and the method which can keep the self safety through the legal system. Fourth, to increase the rate of emergency measure by rescue members, the reasons of fail of emergency treatment are suggested, the treatment results of each rescue member are analyzed every year and it is desirable that the system which can evaluate the personal ability should be introduced. Fifth, the medical accidents occurred in the case of medical act, by rescue members must lake the legal responsibility, but such a problem can he solved with the compensation of insurance system by government. Sixth, to reduce the time required for transfer, traveling service system for the fixed period in beach should be complemented and extended more and service system at ordinary times should be examined at mountains, the area of traffic jams and large special industrial park. Seventh, since service system with one team of two members of 119 rescue party in expressway cannot be mobilized when multiple accidents occur at the same time, it is considered that service system of two teams of four members should be extended. Eighth, first-aid service in expressway is conducted with rescue and emergency treatment by the rescue party at the same time, but the professional rescue lacks and it may result in the injury of patients. Therefore the creation of rescue party in expressway is the urgent problem.

This study is to reduce the rate of drowning accident by using of buoyancy bag. People are exposed to the high risk of drowning accident when they have water leisure activities due to the lack of safety mind-set and shortage of safety products. In case of drowning accident, the rescue action is normally depending on the other people's assistance. Therefore, rescue activities which relyn the people doesn't improve the ratio of survival in the drowning accidents. The submarine specialists should use the buoyancy products to rescue the people in the drowning accident. The citizen can carry portable buoyancy product in the automobile as well as by hands anywhere and anytime. It will be effective rescue tool to save his/her life in the emergency. In addition, it will contribute to rescue other's life because it can be used immediately. There are 3 positive characteristics on the buoyancy bag. First, it is convenience. Documents and other stuffs can be kept in the bag. Second is safety. The material of buoyancy is placed in the inner of the bag. It is possible to float the person whose weight is 90 kg. Lastly, it is durability. It can be used long-term because the outer of the bag is made of anti-water material and anti-water zipper. As a result of performance analysis, it is evident that the buoyancy bag can be used to rescue the people in the drowning accident as a indirect rescue tool compared with the current other rescue products. It is recommended that the design of outer box and performance of buoyancy are required to be improved in order to contribute more to rescue people in the accident.
