Purpose: This study examines the patient problems and nursing interventions during telephone consultations by nurses in an ophthalmology nursing unit. Methods: The data were collected during telephone consultations. A total of 13 nurses consulted 170 patients between September 29 and November 30, 2008 at a tertiary teaching hospital. Problems were raised by the patients and nursing interventions were provided to the patients by the nurses. The SPSS program was used to analyze the data. Results: There were 228 telephone inquiries by 170 patients. The problems were categorized into four groups based on a literature review and validated by 14 nurses: physical symptoms, medications, administrative matters, and follow-up care. Interventions provided by the nurses were categorized into six groups: instructing patients; providing information; providing background knowledge; assuring the patients; referring to the patients to other ancillary departments; and delivering doctor's orders. Conclusions: Nurse interventions for a specific patient problem varied depending on the nurse providing the consultation. The participating nurses expressed the need for a common protocol for telephone consultations. Thus, it would be beneficial to develop a guideline for telephone consultations to minimize practice variations among nurses.

A quantitative analysis was conduct on the economic effect of electronic commerce according to the method of constructing the internet. As a consequence, it was information retrieval cost that had the most cost retrenchment effect in connecting the internet by telephone, which saved about 353,700 won. And it was found that the dedicated line to electronic commerce saved 420,600 won of information retrieval cost and a considerable amount of 319,900 won of brokerage expenses and physical distribution expenses. In terms of value, it was found that the telephone line reduced the time of order process by 8.25%, whereas the dedicated line did so by 9.41% and therefore saved more time than the telephone line. It was found that the dedicated line convenient to use had the higher effect by about 1.2%, respectively than the telephone line in terms of the effective construction of corporate image and the increase of potential buyers. In terms of business management, the intensification of corporate competitiveness improved by 10.00% in case of less than 10 times and by 11.53% in case of 50 to less than 50 times. And it was found that the effect of profit increase as the number of inquiries was large. That is, it was found that the effect of profit increase was 10.88% when the number of inquiries was less than 10 times but it increased to 14.00% in case of 50∼1ess than 100 times. The limitation of this study is that because the size of samples through mail, interview and E-mail was not large, its results have some limitation in applying them to every firm. That is, since the improvement effect of the intrafirm business method, unnecessary repeated manual paperwork and the use effect of being able to maintain the close relationship with to the parties to trades in the process of prompt receipt and delivery of documents are long-term and indirect effects, they have some limitation in that they can not be measured as coefficients but only as scales. Thus, firms using electronic commerce have difficulty enjoying a uniformly identical effect. Therefore, to revitalize electronic commerce, it is thought that government, the academic community and the business world all need to make much research into and sustained investment in electronic commerce.

This paper describes the overall procedure of the development of a digital audio response system. It has been developed specifically as an answering system to the inquiries of telephone numbers from subscribers. The system has been realized based on the residual excited linear prediction (RELP) algorithm that incorporates a pitch predictive loop. Its major advantage over other similar systems is that it produces high quality of synthetic speech, although its memory size is relatively small. The hardware which consists of a speech synthesizer, a controller and an I/O part has been constructed using 2900 series bit-slice microprocessors and an INTEL 8085 microprocessor. The system is capable of real time processing, reliable, and adaptable to other applications.

The aim of this research is to understand the characteristics and status of existing public facilities, in order to propose the necessary basic materials for the planning and development of improved public facilities to assist communities. Objects of this research are the public facilities provided by the Government throughout the 25gu in Seoul. The methods of this research were carried out through the home page of each facility, telephone inquiries and gujung backseo. Investigations were carried out 3 times between the periods of January-June and September in 2009. Results of the research are as follows - 1) Through the investigations of classifications and distribution status of 5 public facilities over 25gu, quantity supply problems were analyzed. 2) Building distributions of 5 public facilities were classified by types and analyzed. 3) A number of compound facilities were classified and analyzed to determine the complexities of the 5 public facilities. 4) Complex types and characteristics of public facilities in 25gu in Seoul were analyzed. Based on the results of the research, the following conclusions are drawn: 1) Public facilities throughout the 25gu in Seoul have common characteristics and functions and they are spread out evenly in each gu. This means that public facilities are standardized in Seoul. Characteristic public facilities suitable to each gu should be planned accordingly. 2) Public facilities in Seoul show a single form of one facility. Therefore, initiative plans for the complexity of facilities are required. 3) Complex public facilities in Seoul need to be the center of community life in each gu. It is necessary to take into account the diverse life styles and classified needs of residents for complex facilities. Based on the research, complex types such as public administrative+cultural facilities, culture+welfare facilities, medical+welfare facilities can be presented. These complex types should not be classified according to any particular use, but they should be commonly used by diverse generations and every social class. The inquiries of users of public facilities and the programs of each public facility are not included in this research. Thus, the reseaarch limits the proposals for complex public facilities. In the future, the characteristics of each gu in Seoul should be studied and understood, so that appropriate public facilities and their complex plans can be researched continuously and necessarily.

In a traditional customer support environment, mainly call centers or service centers are responsible for receiving inquiries from their customers via telephone calls. Due to the rapid growth of Internet with its widespread acceptance and accessibility, means of communication with customers in the traditional customer support center, such as telephones, letters, and direct-visiting, have been replaced by e-mails and bulletin board systems (BBSs) using the Internet constantly. BBSs are basically question and answer systems, they require some lead time to get answer from administrator. To reduce lead time, BBSs enable remote customers or users to log on and tap into a knowledge database that is generally formatted in the form of Frequently Asked Questions (FAQs) that provide answers and solutions to the common problems. And, many different types of the questions are mixed on the BBS. It is a burden to administrator. To build FAQs and to support BBS adminstrator, a supporting tool which is to categorize questions is helpful. In this research, we suggest an interactive question categorizing methodology which consists of steps to present question using keywords, identifying keywords' affinity, computing similarity among questions, and clustering questions. This methodology allows users to interact iteratively for clear manifestation of ambiguous questions. We also developed a prototype system, IQC (interactive question categorizer) and evaluated its performance using the comparison experiments with other systems. IQC is not a general purposed system, but it produces a good result in a given specific domain.

Fault plane solutions of the Iksan earthquake ($M_L=3.85$) and two aftershocks were obtained using the FOCMEC (FOCal MEChanism determination) program. The main event showed the characteristic of strike slip faulting with reverse component. It has the fault planes with NE-SW or NW-SE direction. This is similar to the fault characteristics of earthquake pattern in the inland area of the Korean Peninsula. In order to detect micro-earthquake events, continuous seismic waveform data of the thirteen seismic stations within a radius of 100km from epicenter were analyzed by PQLII program (PASSCAL, 2017) for the period from December 15, 2015 to January 22, 2016. The epicenters of nineteen micro-events were newly determined by Hypoinverse-2000 program. They are not concentrated along some lineaments or fault lines. The intensity of the Iksan earthquake was obtained by estimating the telephone inquiries, the degree of ground shaking or damage all around the southern peninsula. The instrumental intensity was also obtained using PGA (Peak Ground Acceleration) records. As a result, the maximum MM intensity was estimated to be V near the epicenter.

National Cancer Screening Project and Korean Society of Breast Imaging recommend that breast cancer screening should be performed on those aged 40 and above. Nevertheless, this recommendation is usually ignored by a number of medical institutions. The purpose of this study is to emphasize the necessity of an age limitation in screening mammography. Ten institutions were randomly selected and telephone inquiries about patients' age limitation and internal guidelines were set up. The 3,214 women, who underwent screening mammography through 'GE Senography 2000D' in each hospital, were classified into five groups according to age(from 20s to 40s, at intervals of 5). And then, collected data was analyzed by a radiologist in accordance with ACR-BIRADS(American College of Radiology Breast Imaging Reporting and Data System), through which breast parenchymal density and the results of analysis were categorized in order to predict the sensitivity of mammography. Information about craniocaudal-view mammograms was automatically produced by use of GE Senography 2000D, and the average glandular dose was retrospectively analyzed through the program 'Excel 2007.' Two institutions did not set the age limitation. Other seven institutions internally allowed those who wanted to receive mammography regardless of age. Approximately 99% of those aged 20 to 29 were judged as having the dense breast. In those aged 35 to 39, breast parenchymal density tended to be lower, but the fatty breast to increase. In the case of 'category-zero' that does not need additional tests, the rate of 'heterogeneously dense' and 'extremely dense' reached to 83.1% and 15.1% respectively. Regarding dense breasts, there was no sufficient information for image reading. The glandular dose, applied to 3,214, was 1.47mGy on the average. In those aged 20 to 24 who are sensitive to radiation, the average glandular dose indicated 1.59mGy. Those aged 35 and above showed the lowest value, 1.43mGy. In those aged 35 to 39, the breast tended to change from denseness to fattiness. The average glandular dose was lowest in those aged 35 and above, which suggests that screening mammography should be periodically performed on those aged 35 and above in order that breast cancer may be early detected. On the other hand, in those aged less than 35, it is difficult to analyze mammograms due to the high density of breast parenchyma, and also retakes become frequent. In particular, subjects may be exposed to excessive doses. Accordingly, it should be substituted by breast self-examination or clinical breast examination. In case of need, it is advisable to perform ultrasonography.

Korean citizens enjoy not only the freedom of communication but also the secrecy of electronic communication. Article 18 of the Constitution of the Republic of Korea prescribes that the secrecy of correspondence should not be infringed. Namely, all citizens enjoy guaranteed privacy of correspondence. But many people have been experiencing the infringement of those rights. The purpose of this paper is to evaluate whether Paragraph 2, Article 13 of the Act on Protection of the Secrecy of Correspondence infringes on the constitutional rights of privacy of electronic communication. The results of this study indicate that the law violates the Constitution. Paragraph 3, Article 12 (Personal Liberty, Personal Integrity) of the constitution stipulates that "Warrants issued by a judge through due process (upon the request of a prosecutor) have to be presented in case of arrest, detention, seizure, or search." However, prosecutors, the police, and National Intelligence Service have made numerous inquiries calling for the journalists' telephone records without warrants issued by a judge. So, this study suggests that the paragraph should be amended to be compatible with the Constitution. Meanwhile, journalists should make a more concerted effort to protect their news sources in exercising constitutionally protected freedom of the press.

Test turnaround time (TAT) is the lead time from reception to reporting. In the complete blood cell count (CBC), 4 units of the XE-2100 (Sysmex Corp., Japan) processed around 80% of quantity, 1 unit of the LH-780 (Beckman-Coulter Incorp., USA) processed around 10% and 1 unit of ADVIA-2120 (Siemens AG, Munich, Germany) processed around 10%. We analyzed the change in the TAT for the CBC for over 7 years, from January of 2005 to December of 2011. The delta check made alterations of delta to WBC, hemoglobin, hematocrit, platelet and metamyelocyte, however, did not made them to band neutrophil, eosinophil, basophil and monocyte. The panic value check made alterations of panic value to hemoglobin, hematocrit, platelet and monocyte. In the criteria of currently slide review, LH-780 and ADVI-2120 analyzers prepared suspect flags of "Blast, Imm NE2, Immature granulocyte, Imm NE1, Left shift, Variant lymphocyte, Atypical lymphocyte, Platelet clumps and NRBC". The New slide review in the XE-2100 analyzer altered the preparations of a smear slide more than a "Platelet clumps flag(${\geq}200unit$), a single flag excluding the "Platelet clumps flag (${\geq}250unit$) and a multiple flag (${\geq}200unit$)". Also, below the 240 unit, medical technologists prepared manual slides selectively according to their evaluations. The automatic reporting rate was 33.4% without alterations, whereas it was 41.0% without alterations, and was thus improved by 7.6%. The slide review rate was 15.2% before using the Q-flag limit, whereas it was 12.1% for a reduce 3.1%. TAT was 45 minutes without the creation alterations of the delta and panic value checks, whereas it was 35 minutes after making alterations of the delta and panic value checks and thus was shortened by 10 minutes. We came to the conclusion that the establishment and operation of delta and panic value checks and slide review criteria suitable for laboratory environment can reduce unnecessary smear slides, re-checking, re-sampling, re-testing, telephone inquiries and concentrated workloads during specific times of the day.

Background: This study focuses on the establishment and operation of a stroke patient hotline program to help patients and their caregivers determine when acute neurological changes require emergency attention. Method: The stroke hotline was established at the Gyeonggi Regional Cerebrovascular Center, Seoul National University Bundang Hospital, in June 2016. Patients diagnosed with stroke during admission or in outpatient clinics were registered and provided with stroke education. Consulting nurses managed hotline calls and made decisions about outpatient schedules or emergency room referrals, consulting physicians when necessary. The study analyzed consultation records from June 2016 to December 2020, assessing consultation volumes and types. Outcomes and hotline satisfaction were also evaluated. Results: Over this period, 6,851 patients were registered, with 1,173 patients (18%) undergoing 3,356 hotline consultations. The average monthly consultation volume increased from 29.2 cases in 2016 to 92.3 cases in 2020. Common consultation types included stroke symptoms (22.3%), blood pressure/glucose inquiries (12.8%), and surgery/procedure questions (12.6%). Unexpected outpatient visits decreased from 103 cases before the hotline to 81 cases after. Among the 2,244 consultations between January 2019 and December 2020, 9.6% were recommended hospital visits, with two cases requiring intra-arterial thrombectomy. Patient satisfaction ratings of 9-10 points increased from 64% in 2019 to 69% in 2020. Conclusion: The stroke hotline program effectively reduced unexpected outpatient visits and achieved high patient satisfaction. Expanding the program could enhance the management of stroke-related neurological symptoms and minimize unnecessary healthcare resource utilization.
