A power-efficient neuromodulator is needed for implantable systems. In spite of their stimulation signal's simplicity of wave shape and waiting time of MCU(micro controller unit) much longer than execution time, there is no consideration for low-power design. In this paper, we propose a novel of low-power algorithm based on the characteristics of stimulation signals. Then, we designed and implement a neuromodulation software that we call NMS(neuro modulation simulation). In order to implement low-power algorithm, first, we analyze running time of every function in existing NMS. Then, we calculate execution time and waiting time for these functions. Subsequently, we estimate the transition time between active mode (AM) and low-power mode (LPM). By using these results, we redesign the architecture of NMS in the proposed low-power algorithm: a stimulation signal divided into a number of segments by using characteristics of the signal from which AM or LPM segments are defined for determining the MCU power reduces to turn off or not. Our experimental results indicate that NMS with low-power algorithm reducing current consumption of MCU by 76.31 percent compared to NMS without low-power algorithm.

Peer-to-Peer (P2P) systems with super-peer overlay networks show combined advantages of both hybrid and pure P2P systems. Super-peer is a special peer acting as a server to a cluster of generic peers. Organizing a super-peer network is one of important issues for P2P systems with super-peer networks. Conventional P2P systems are based on two-level hierarchies of peers. One is a layer for generic peers and the other is for super-peers. And it is usual that super-peer networks have forms of random graphs. However, for accommodating a large-scale collection of generic peers, the super-peer network has also to be extended. In this paper, we propose a scheme of hierarchically constructing super-peer networks for large-scale P2P systems. At first, a two-level tree, called a simple super-peer network, is proposed, and then a scheme of generalizing and then extending the simple super-peer network to multi-level super-peer network is presented to construct a large-scale super-peer network. We call it an extended super-peer network. The simple super-peer network has several good features, but due to the fixed number of levels, it may have a scalability problem. Thus, it is extended to k-level tree of a super-peer network, called extended super-peer network. It shows good scalability and easy management of generic peers for large scale P2P system.

The purpose of this study was carried out to evaluate the satisfaction relate to health examination of National health insurance service in Busan. This paper provide basic information of conducted by the National Health Insurance service, and the perception of health examination to provide satisfaction. The sampling group was selected in Busan's health examinations tests can be conducted targeting. Distributed 300 questionnaires were used in the final paper, call 221 and survey was accomplished between March and th June in 2013. The analyzed results was as followed; 1) There was significant of have used medical examinations; have medical institutions use 1 month ago; cigarette smoking day; the number of drinking by demographic characteristics, the statistic difference was existed on.(p<0.05, p<0.01) 2) The satisfaction of health examination institutions were recorded to average $3.22{\pm}0.52$ points on 5-points scale; Opinion the health examination services average was $3.31{\pm}0.55$ points on 5-points scale; attitude to health examination average was $3.73{\pm}0.54$ points on 5-points scale.
Allozyme study for open pollinated seeds of forty nine pitch pine families in an $F_1$-hybrid seed orchard demonstrated that allozyme variants in aspartate aminotransferase(AAT), glutamate dehydrogenase(GDH) and leucine aminopeptidase(LAP) systems are encoded by at Least eight loci; five for AAT, one for GDH and two fur LAP. Allozyme variations showed polymorphisms at seven of the eight loci, except GDH. Average number of alleles examined over six loci were 2.33 and 2.67 for maternal and progeny groups, respectively. Average heterozygosity and genetic diversity computed over six loci were, respectively, 0.235 and 5.409 for maternal tree group, 0.238 and 5.569 for progeny group. The proportion of $F_1$-hybrid seeds estimated by allozyme analysis was 0.77%. The estimated proportion of $F_1$ hybrid seeds by allozyme study is in good agreement with the value 0.73% estimated by morphological study for the proportion of pitch ${\times}$ Loblolly $F_1$ hybrid seedlings at a nursery. Indications for Wahlund effect, high levels of self-fertilization and for non-random matings in the $F_1$ hybrid seed orchard call for cautions in estimating allele frequency changes and mating probabilities for the parental and progeny groups.
Personal information processing works, including resident registration number is common to be consigned by IT specialized company due to high level expertise and tremendous cost. The accident related to personal information is increasing and most of accidents are caused by the consignee's leaking information. According to the Inspection of personal information protection and the management level diagnosis of personal information protection, public Institutions need to build the consignee's accident prevention and personal information management system as soon as possible. In this paper, the efficient enhancement ways for the personal information protection is studied. We analyze the law of business consignment and select basic management items related with personal information protection, and propose a analysis scheme for management level of personal information protection and a enhancement scheme for management system of personal information protection. This paper suggests consignee's management system of personal information protection for the enhancement way and the three Strengthening ways in law. To compose the a enhancement scheme for management system of personal information protection, we conduct questionnaire survey to 30 consignees(IT maintenance, notice printing, call center, welfare center) related to typical tasks of public organizations, present reference for this scheme, and execute verification of this scheme by focus group interview of consignor and consignee.
In this paper, definitions of biyoul and value of bi in elementary mathematics in Korea are critically analysed. And identity of halpunri is reviewed. Regarding biyoul, it is suggested that the use of term 'biyoul' is restricted to such cases when the quantity to be compared and the quantity to be a base have same measuring unit, without consider ing biyoul in terms of two numbers. it is suggested to use "the number which express how many times the quantity to be compared is contained by the quantity to be a base is called biyoul." as a definition of biyoul. It is suggested to use "value of bi A : B is A/B" as a definition of value of bi. Halpunri is a variation of halbunri, which is coined by putting hal, pun, and ri together in purpose of using in school mathematics. The tem1 corresponding halpunri is 'bohap', however, in this paper it is suggested to use halpunri after defining it instead of using bohap. In that halpunri is an acclimatized term of bohap, and considered as a biyoul not as a way to indicate biyoul, it is suggested to use "biyoul when the quantity to be a base is considered 10." as a definition of halpunri. It is suggested to see hal, pun, and ri are units for halpunri, and call decimal 0.1 expressing biyoul 1 hal, decimal 0.01 expressing biyoul 1 pun, decimal 0.001 expressing biyoul 1 ri respectively.

Objectives : This study is retrospective chart review research on the combined-prescription of Western and Korean medicine in Public Health Center in rural area. Methods : Researchers reviewed medical records of patients who was prescribed Korean medicine and Western medicine from 1st, Jan, 2019 to 31st, Dec, 2019 in Public Health Center. 50 patients' medical records were included. Results : Total number of treatment is 3,808 cases and 1.3% of them is prescribed Korean medicine and Western medicine simultaneously. Prescription of Korean medicine is 153 cases and Western medicine is 160. Jowiseunggi-tang and Diroba tablet were the most frequently prescribed Korean medicine and Western medicine. Furthermore, Korean Medicine Doctors of Public Health Center use muscular skeletal disease system code(M code among KCD code) for prescription and Western Medicine Doctors use diseases of the circulatory system(I code among KCD code) frequently. Conclusions : We analyze 50 patients who were prescribed both Korean medicine and Western medicine. Mostly, patients were prescribed medicine for different diseases in each clinic. In western medicine clinic, drugs about circulatory or endocrine disease were prescribed frequently and in Korean Medicine clinic, drugs about muscular skeletal disease were most frequently prescribed. This result imply the real world's combination of prescription status that was different from result of National health insurance corporation database. Senior patients in rural area take medicine long period and have various underlying disease. We call for some attention about senior and rural area patients' prescription status in interaction studies of Korean medicine and Western medicine.

This paper is the study on the Medium Designator in Non-book materials. Main contents of this study were as follows; 1. The medium designator serves to indicate the class of material to which an item belongs. This is used to give an 'early warning' ;to the catalogue user. 2. This medium designator may be further divided into two elements ; a general material designation (GMD), for example video-recording, and a specific material designation (SMD), for example, videodisc. 3. GMD: In cataloging, a term indicating the broad class of material to which a bibliographic item belongs, such as 'motion picture', and SMD : In descriptive cataloging, a term indicating the special class of material (usually the class of physical object) to which a biblographic item belongs, such as videocassette. 4. Locating the medium designator after the title proper was not prescribed until ISBD(G) and AACR2. In pre-ISBD(G) codes, the ,early, warning type of medium designator was placed after all title information. But in AACR2, the medium designator is placed after the title proper, but before parellel title and other title information. 5. In Terminology, Two separate lists of designations are given in AACR2, l.1C1, one for British and one for North American use. The British list contains fewer terms, and uses generic categories to group together some of the North American list. 6. The problem of where to place the medium designator might be circumvented by using some kind of early alerting device other than a formal element of biblliographic description. Various alternatives have been suggested. A more popular device is the provision of symbols or 'media code' which are part of the call number and indicate the porticular medium type. 'Colour-coding' the use of used by some libraries but is now longly discouraged. 7. According to Frost. The medium designatorhas been generally reeognized as serving three functions; 1) as a statement of the nature or basic format of the item cataloged and thus as a meant of informing the user as to the type of material at hand; 2) as a description of the physical charaetistics of medium and as a means of alerting the user to equipment needed to make use of the item. 3) as a device to distinguish different physical formats which share the same title. 8. AACR2 raises some problems which decision makers have neet had to face preriously It provides a GMD for every item in the collection including books and it makes the application of any or all GMD's optional.
This study was a research study to find out the real picture and practice of student obesity control by primary, middle and high school school nurses. The study sampled 196 school nurses working in the Busan City and Northern Gyungsang Province, who agreed on the purpose of the study. When it comes to the study process, at the meeting of the whole school nurses, the researcher explained the purpose of the study and asked them to complete questionnaires and return on the spot. The study is designed to provide basic data for school nurses in field to systematically and efficiently control student obesity by examining perception of school obesity control and the real picture or practice of obesity control as well as its problems. The study used SPSS 10.0 to analyze data. The results are as follows: Annual plans about obesity control appeared significant at the primary school, 89.3%, higher than 77.3% of the middle and high school(p<0.05). Annual project evaluation showed a significant difference by regions, 56.0% of metro cities vs. small cities(p<0.01). The number of measuring weight of obese students was higher at the primary school than at the middle and high school(p<0.05). Also small cities conducted the weight measurement more often than metro cities(p<0.001). Among the health education methods for obesity, counseling appeared statistically significant(p<.01). The health education showed a significant difference in more experienced school nurses. Among the educational media, environment postings were used at the primary school, 24.0%, higher than 5.3% of the middle and high school. It showed a significant difference(p<.001). OHP or epidiascopes were used at the primary school, 36.4%, significantly higher than the middle and high school(p<.001). In addition, computer was used at the primary school, 21.5%, higher than the middle and high school(p<.05). Problems of obesity education data included a lack of textbooks and programs and a short of educational media. However it didnt show a significant difference in schools or in regions. Counseling activities for obesity showed a significant difference in schools(p<.01) and in regions(p<.001). When parents with obese students were in counseling, those in their 20s used home correspondence and those in their 30s and 40s used phone call(p<.01). The rate of equipment to measure obesity was higher at the middle and high school than the primary school, showing a significant difference(p<.001). Therefore, regular health education curriculums for school nurses should be systematically created to promote student health. Furthermore, it needs to make standard textbooks for health education by grades as well as by levels and to develop various educational programs and educational media.

With the use of many rivers increased nearly to the capacity, the need for information concerning daily quantities of water and the total annual or seasonal runoff has became increased. A systematic record of the flow of a river is commonly made in terms of the mean daily discharge Since. a single observation of stage is converted into discharge by means of rating curve, it is essential that the stage discharge relations shall be accurately established. All rating curves have the looping effect due chiefly to channel storage and variation in surface slope. Loop rating curves are most characteristic on streams with somewhat flatter gradients and more constricted channels. The great majority of gauge readings are taken by unskilled observers once a day without any indication of whether the stage is rising or falling. Therefore, normal rating curves shall show one discharge for one gauge height, regardless of falling or rising stage. The above reasons call for the correction of the discharge measurements taken on either side of flood waves to the theoretical steady-state condition. The correction of the discharge measurement is to consider channel storage and variation in surface slope. (1) Channel storage As the surface elevation of a river rises, water is temporarily stored in the river channel. There fore, the actual discharge at the control section can be attained by substracting the rate of change of storage from the measured discharge. (2) Variation in surface slope From the Manning equation, the steady state discharge Q in a channel of given roughness and cross-section, is given as {{{{Q PROPTO SQRT { 1} }}}} When the slope is not equal, the actual discharge will be {{{{ { Q}_{r CDOT f } PROPTO SQRT { 1 +- TRIANGLE I} CDOT TRIANGLE I }}}} may be expressed in the form of {{{{ TRIANGLE I= { dh/dt} over {c } }}}} and the celerity is approximately equal to 1.3 times the mean watrr velocity. Therefore, The steady-state discharge can be estimated from the following equation. {{{{Q= { { Q}_{r CDOT f } } over { SQRT { (1 +- { A CDOT dh/dt} over {1.3 { Q}_{r CDOT f }I } )} } }}}} If a sufficient number of observations are available, an alternative procedure can be applied. A rating curve may be drawn as a median line through the uncorrected values. The values of {{{{ { 1} over {cI } }}}} can be yielded from the measured quantities of Qr$.$f and dh/dt by use of Eq. (7) and (8). From the 1/cI v. stage relationship, new vlues of 1/cI are obtained and inserted in Eq. (7) and (8) to yield the steady-state discharge Q. The new values of Q are then plotted against stage as the corrected steadystate curve.
