Tuberculous cervical lymphadenitis is one of the most common causes of neck mass in Korea. But the diagnostic confirmation is difficult and it's effective treatment modalities are still in controversy. Through a retrospective study of 32 cases of tuberculous cervical lymphadenitis treated with surgical treatment during recent 4 years, we have analyzed 5 subtypes of CT finding and surgical treatment modalities and received following results 1. The locations of lymphadenitis were posterior triangle(12 cases), submandibular area(9 cases), supraclavicular area(8 cases), submental area(2 cases), and parotid area(1 case). 2. Five subtypes of CT findings were observed : Homogeneous enhancement type(3 cases), peripheral rim enhancement type(6 cases), peripheral rim enhancement with perinodal fat obliteration type(12 cases), coalescent cold abscess type(8 cases), and mixed type(3 cases). 3. Surgical treatment modalities : Excision (13 cases), incision and drainage(9 cases), selective neck dissection(8 cases), and curettage(2 cases).

Purpose: This study was to investigate the nationwide operational status of the professional medical support staffs (PMSS) who practice the expanded roles in the hospital setting. Methods: The data were obtained through survey from 36 hospitals with over 500 beds from 25th May to 12th July 2016. Data from 1,666 PMSS were analyzed. Results: Since the job titles varied, we classified them into 5 groups according to their roles; advanced practice nurse, clinical nurse expert, PA (physician assistant), coordinator, and others. There were differences in the operation status of PMSSs depending on the region, nurse staffing grade and number of hospital beds. Qualification criteria varied from hospital to hospital, and almost half of the hospitals didn't have any qualification standards for them. There were differences in age, educational level, clinical careers, rewards, and job satisfaction in 5 groups. Especially PA group had low salary, poorer working conditions, more difficulties in performing their work, and lower job satisfaction than other groups. Most PMSS (99.5%) were using a delegated prescription authority, however only 68.3% had job description and 19.9% had documented delegated role. Conclusion: Adequate training curriculum, documented delegated roles, and the protocols for legal protection and efficient medical services are needed.

This study was carried out to investigate the job performance, perception of job importance, and job satisfaction in dietitians working in geriatric hospitals in Busan. A survey was conducted from April 28 to June 30, 2011, and the data were analyzed using the SPSS program. The age of over 41 group showed higher job performance in terms of sanitation and safety management than the age of under 25 group but showed lower job performance in terms of nutrition management than the age of 31~40 group. The subjects who worked for shorter than 2 years at their present jobs showed the lower job performance in terms of menu management and accounting management than the other groups, whereas those who worked in 'over 200 bed' hospitals showed the higher job performance in terms of sanitation and safety management than the others. The subjects who worked for longer than 6 years showed the higher job satisfaction in terms of communication and working environment than the others. Job performance showed a significant positive correlation with perception of job importance, whereas it showed no significant correlation with job satisfaction. More work experience correlated with a higher monthly income, and younger workers showed higher job performance. Younger age and more work experience at a present job correlated with a higher perception of job importance. More work experience at a present job, higher monthly income, and shorter work experience were correlated with higher job satisfaction. These results suggest that it would be effective to adopt training programs for appropriate nutrition service and provide continuous education programs for professional development.

This study reviews equipped with enhanced capability of medical care, quality service, accessibility, and consumer awareness to be a competitive and representative local healthcare service provider with improved administrative efficiency. The method of analysis are ANOVA and Structural Equation Modeling. The results which revealed the significant difference among demographic factors in determining the preference or degree of satisfaction at medical service to select local healthcare institutions suggest that the close review on the needs of groups of major customers of local healthcare institutions are necessary when preparing the strategy of specialized medical service of local healthcare institutions. this suggests that both images would be important factors to secure the competitive advantage of local healthcare institution and therefore the strategy maximized the enhancement of medical service with embossed image of hospital to attract customers of medical service is needed.

The previous researches on customer participation(CP) have examined the influences of CP on customer satisfaction and service quality focusing on the role of CP in the service encounters. However, this paper identifies the path relationships between CP and relationship commitment focusing on the impact of CP on the relational outcomes. By expanding the role of CP in the service encounter, this paper shows what relational variables can be influenced by CP in detail, which identifies that CP plays an important role in service encounter empirically. As results, CP has significant influences on the relationship commitment such as normative commitment, continuance commitment, and affective commitment respectively. Additionally, considering the characteristics of CP, CP is more impactful on normative commitment than affective commitment.

Although multilayer perceptrons (MLPs) present several advantages against other pattern recognition methods, MLP-based speaker verification systems suffer from slow enrollment speed caused by many background speakers to achieve a low verification error. To solve this problem, the quantitative discriminative cohort speakers (QnDCS) method, by introducing the cohort speakers method into the systems, reduced the number of background speakers required to enroll speakers. Although the QnDCS achieved the goal to some extent, the improvement rate for the enrolling speed was still unsatisfactory. To improve the enrolling speed, this paper proposes the qualitative DCS (QlDCS) by introducing a qualitative criterion to select less background speakers. An experiment for both methods is conducted to use the speaker verification system based on MLPs and continuants, and speech database. The results of the experiment show that the proposed QlDCS method enrolls speakers in two times shorter time than the QnDCS does over the online error backpropagation(EBP) method.

Elderly with dementia in geriatric hospitals (EDGH) are highly dependent on hospital meals. This study evaluated the foodservices satisfaction and food preference of the EDGH. The survey was conducted on 104 elderly with dementia (21 males and 83 females) in 4 geriatric hospitals in Seoul and Incheon in November, 2016. Data were collected from interviews using a questionnaire that consisted of 6 questions for foodservice satisfaction and 24 questions (10 categories) for food preference. The data were analyzed using SPSS ver. 20.0. The satisfaction with taste, saltiness, texture, and variety in foodservices was good, but the satisfaction with the amount was not, and the reason for leaving food was its large serving size. The subjects preferred soft boiled rice, noodles, porridges, meats, fish, seafood, vegetables, and fruits. Among them, they preferred more janchiguksu, red bean porridge, beef, croaker, oyster, spinach, and banana. Regarding the cooking methods, they preferred soup, grill, and boiling, but not frying. The also preferred Chinese cabbage kimchi, but they did not prefer hard kkakdugi. They did not prefer milk because of diarrhea, but they preferred yogurt. Therefore, to provide a satisfying meal for EDGH, it is necessary to develop a friendly diet considering their food preferences.

Objectives : The SERVQUAL scale is based on gap theory, which suggests the difference between consumers' expectations and the quality of the medical service actually received. However, problems in the implementation of the SERVQUAL scale have been identified by several researchers. Some researchers have proposed a simple performance-based measure (SERVPERF) or au exportation-controlled performance-based measure(Non-Diff) as alternatives to the SERVQUAL scale. On the basis of the theoretical concerns discussed, we examined the capability of each of the three scales(SERVQUAL, Non-Diff, SERVPERF) to explain variations in consumer satisfaction. Methods : Data was gathered from a self-administered questionnaire in a 430 bed hospital. Questionnaires evaluating medical services were distributed to 180 ambulatory patients. A total of 167 usable questionnaires were gathered. The questionnaire was composed of 10 expectation, performance and expectation-controlled performance items. In addition, overall satisfaction and purchase intention were measured. Results : Compared with the SERVQUAL scale, the Non-Diff and SERVPERF scales better explained the observed variations in consumer satisfaction(SERVOQUAL, $R^2=0.29;\;Non-Diff,\;R^2=0.51;\;SERVPERF,\;R^2=0.48$) and purchase intention(SERVQUAL, $R^2=0.22;\;Non-Diff,\;R^2=0.33;\;SERVPERF,\;R^2=0.34$). Conclusion : The maier conclusion from our study is that the Non-Diff and SERVPERF scales are more efficient in assessing consumer satisfaction than the SERVQUAL scale. Therefore we suggest that consumer satisfaction he measured by the Non-Diff or SEVPERF scales.

This paper discusses system for real-time monitoring of patient waiting time in hospitals based on open-source platform. It is necessary to make use of open-source projects to develop a high-performance stream processing system, which analyzes and processes stream data in real time, with less cost. The Hadoop ecosystem is a well-known big data processing platform consisting of numerous open-source subprojects. This paper first defines several requirements for the monitoring system, and selects a few projects from the Hadoop ecosystem that are suited to meet the requirements. Then, the paper proposes system architecture and a detailed module design using Apache Spark, Apache Kafka, and so on. The proposed system can reduce development costs by using open-source projects and by acquiring data from legacy hospital information system. High-performance and fault-tolerance of the system can also be achieved through distributed processing.
