The dental insurance had been enforced in Korea past 20 years. The major part of the insurance was filling, and the filling was divided into two parts-the cavity preparation and cavity filling, The Cavity filling was estimated into 6 levels according to the cavity types. But the tooth cavity preparations was not evaluated by the cavity types but merely only one-the one visit filling or cavity preparation. Korean dentists tend to turn away from the amalgam to the non-insurance treatments. The purpose of this study was to relate the cavity preparations and cavity fillings to the cavity types. So I measured the real time and surveyed the relative difficulties of cavity preparations from the 31 dentists according to the cavity types, who had been trained in conservative dentistry. The conclusion of this study was below. 1. The estimations of tooth cavity preparation was divided same as the cavity filling. 2. There must be reasonable considerations about the times and difficulties in cavity preparation. 3. There was differences between the premolars and molars, upper jaw and lower one. 4. Two or more cavities in one tooth must be evaluated according to the number of cavities, not in one cavity.

Purpose: This study aimed to explore the difficulties and coping that advanced practice nurses (APNs) experience in home health nursing field. Methods: The participants were 12 APNs who had experience in home health nursing for over 5 years. Data were collected through two focus group interviews between August and September, 2017. The results were analyzed using a qualitative content analysis. Results: Out of 10 sub-categories and 29 codes, 4 categories emerged: "crushed by the responsibilities as the only healthcare professional", "worn out by family who interfere with work", "anxiety about my safety being threatened" and "using self-learned know-hows". Conclusion: APNs face difficulties due to the environmental characteristics of the homes, the characteristics of chronically critically ill (CCI) patients and their families, and legal or systematical limitations when dealing with problems based on their personal competence. In order to ensure that professional nursing care is more readily provided to CCI patients through home health nursing services in local communities, it is imperative that support systems at the organizational and institutional levels be established in a systematic way to resolve the issues faced by APNs.

Purpose: The purpose of this study was to compare the neonatal birth weight, birth height, Apgar scores, sucking power, and digestion difficulties between smoking and non-smoking women following cesarean birth. This study analyzed the effects of smoking on the neonatal health status in pregnant women to provide fundamental data for smoking prevention education for women of childbearing ages and non-smoking practice protocols for pregnant women with smoking. Methods: A comparative survey design was used. Fifty-four newborn infants of pregnant women with smoking and seventy-four newborn infants of pregnant women with non-smoking participated in this study. The scores of neonatal birth weight, birth height, Apgar scores, sucking power, and digestion difficulties were assessed. Data were analyzed using SPSS Windows 15.0 program. Results: Smoking in pregnant women leads to the decrease of birth weight (F=4.75, p=.030) and birth height (F=14.19, p<.001), negative effects on the Apgar scores (F=36.02, p<.001) and sucking power (t=-4.26~-5.60, p<.001), and digestion difficulties ($x^2$=6.72, p=.010) of neonates. Conclusions: This study demonstrated that smoking in pregnant women leads to the decrease of fetus development. These findings would be utilized for the development of not only smoking prevention programs for women of childbearing ages but also prenatal education programs for pregnant women.

The purpose of this study is to diagnose difficulties and problems that the preservice teachers experience when teaching inquiry-based classes in elementary science and to improve their professionalism through prescriptive instruction consulting utilizing PDRE (preparation, diagnosis, reflective implementation, evaluation) model. The result of this study was as follows. First, preservice teachers considered themselves to be lack of scientific knowledge, but this study confirmed that the application of instruction consulting improved their understandings in scientific concepts and principles and corrected their misconceptions. Second, preservice teachers experienced difficulties in variables that might influence the results of experiments, cautions for the experiments and unexpected results of experiments, and this consulting allowed them to gain instruction ability to cope with such circumstances and solve problems effectively. Third, preservice teachers experienced difficulties in applying instructional model into their classes and preparing lesson plans, but consulting actually made limited but positive changes in their abilities. However, from a longer-term perspective, quantitative increase in their teaching opportunities, the development and distribution of example manuals, and the utilization of various class materials provided by the assistant centers for teaching and learning should be achieved side by side.

This paper explores not only emerging scientific problems but also the difficulties communicating air quality issues into an increasingly sensitive the public and policy arena. The public understanding and trust in air pollution information and indices may be very different to the notions of validity or accuracy that are important for a scientist. We operate in a world where openness requires us to reveal both the difficulties and disagreements in our understanding of the polluted atmosphere. Yet this can be confusing and increase complexity in situations where clear political and social decisions are required. I am going to examine these issues, starting with questions of what substances we regard as pollutants and the difficulties of getting the correct balance of concern given the broadening the base of chemicals emitted to the environment. There are also questions of exposure particularly in terms of vulnerable populations, who may spend large amounts of time indoors, where air is rarely monitored. In contemporary society there are pollution problems that extend far beyond urban areas and we have to consider regional issues such as windblown dusts, smoke from forest fires along with issues of the emission of green house gases and ozone depleting substances. Finally I will discuss the issues of communicating with a concerned public and sceptical politicians and the troubling interface between technological and sociological control. Such complexity is often missed in a maze of seemingly stronger political and social needs.

Purpose: This follow up study was performed to survey the problem in performing ADLs at home after surgery. Method: Twenty elderly patients were assessed 3 times; from the time of hospitalization for surgery until 3 weeks after discharge. Measuring tools are numeric rating scales (NRS) for pain and 3 questionnaires developed by the authors to measure difficulties in ambulation, performing indoor ADLs, and emotional status. Pearson correlation, variance analysis and descriptive statistics were used to analyze the data. Result: The level of pain significantly decreased after surgery, but the difference between pain at the time of discharge and that of 3 weeks after discharge were not significant. Pain showed a positive relationship with emotional difficulties. Elderly with a higher education, family caregiver, and regular exercise showed a lower level of emotional difficulties. Conclusion: Comprehensive approaches for chronic pain including physical, psychological, and social aspects should be considered when caring for the elderly with spinal surgery. In addition, home care nursing interventions should include an exercise program to promote adaptation and rehabilitation after discharge.

The Korean textile industry the driving force of Korea's economic development, is faced with difficulties due to domestic and foreign influences. The purpose of this paper is to examine what measures are necessary for overcoming such difficulties. As the first step, We conducted a month-long survey, in August 2003, of 157 small-medium firms operating in the Korean textile industry to collect information about difficulties that they face in carrying out their business. According to the result, small firms performed badly in sales and facility investment efforts for 2003 due to worldwide economic depression. They, however, actively pursued new technology development in order to improve their competitiveness. Profits and productivity decreased with reduced sales, and their view on the next year’s perspective is also very unfavorable. Especially many firms intend to maintain or even lower the level of sales goal for 2004, reflecting the sluggish market environment. According to the survey, under such circumstances, as many as 74% of firms wanted to turn the tables through the development of highly sensuous material and improved marketing efforts. One of potential answers to this problem, which is suggested by the survey, is to establish a consulting service institution to provide promptly marketing data and information on textile and fashion market and trend in Italy. Especially, firms surveyed have shown a great deal of interest in Italian consulting service for new textile material developments. While they want the service for high value-added product development, they are reluctant to do so because of the uncertainty of its future effects and high consulting fees.

GIS 기법은 다양하게 이용되어 왔다. 본 연구는 대구시내에 위치한 은행(銀行) 점포(店鋪)들의 입지변동(立地變動)을 GIS기법에 의하여 분석한 것이다. 한 도시내에 은행(銀行) 점포(店鋪)의 입지변동(立地變動)은 도시지리학(都市地理學)과 도시계획학(都市計劃學)에 있어서 중요한 의미를 지닌다. 은행(銀行) 점포(店鋪)의 위치는 실물경제(實物經濟)에서 소비와 생산의 흐름을 대변(代辯)해 주고, 공간적으로 도시경제(都市經濟) 동심(重心)의 이동을 파악할 수가 있어, 도시연구(都市硏究)에 주요한 과제가 되고 있다. 그러나, 은행의 입지변동(立地變動)에 관한 전통적인 지동중첩(地圖重疊)으로는 연구의 한계가 있다. GIS기법은 전통적(傳統的)인 기법(技法)으로 가능한 연구의 한계를 넘어선 연구가 가능하였다.
