Recently introduced PLS (positive list system) policy in Korea intends to gain cost effective in drug expenditure, by allowing reasonable prices relative to products` effectiveness. Under the increasingly constrained health budget situation, it is a reasonable policy tool to be used in any country. However, it does not allow one, as contrary to one easily hopes, to control total drug expenditure. In terms of health policy tools for drug expenditure management, if controlling drug expenditure were set as an objective of health policy in one`s setting, one may need additional tools. One such tool Korea can think of under the current situation of rapidly rising drug expenditure is the fixed budget for pharmaceuticals. It would be rather a stringent policy tool from the pharmaceutical industry`s point of view, but if one extends the perspective to society level, it can be considered as a reasonable option. In particular, as in Korea where pharmaceutical policy has been mostly in the form of price control, management of drug expenditure can now be extended toward quantity control as well. Fixed drug budget(FDB), in that regard, is an option open to Korea now. If FDB is considered as a possible policy option, a carefully designed impact analysis from all different angles is strongly encouraged. This is because the same policy could have different kinds and level of impacts under different health care systems. No matter what, it is about time for Korea to consider FDB as a drug policy option.

General expectation on generics is that they will bring about substantial savings of drug expenditures by substituting their expensive branded counterparts. So far in Korea, not much empirical studies done in this area. Recent Korean policy intervention on generics is focusing on the price cut under the assumption that lowering price would directly be linked to curtailment of drug expenditures. This study aims to investigate the savings on drug spendings with the introduction of generics. NHI claims data of 6 substances - Pioglitazone, Voglibose, Metformin, Glimepiride, Tolterodine, Clopidogrel - are used to examine the expected impact of generics. Drug spendings of 2009 were compared with those of 2006. Each substance in the study is considered to have experienced strong generic adoption since 2006. The results are the followings. Generic introduction contributed to about 70%~216% increase in drug expenditures, The quantity effect was positive for all substances with increasing rate of 1.13~3.90. This implies that generic introduction created new market for survival rather than jumped into the original market to compete with, Drug mix effect of generic introduction in all substances in the range of 0.83~0.97, impling that original drugs had been slightly substituted for generics during the period under study. A salient feature of this study is that after the generic introduction, use of generics has increased along with their original counterpart. In other words, the volume of original drugs hasn``t been decreased but increased instead. The only exception was the case of Pioglitazone. In conclusion, Even when the generics were actively introduced, we could not witness the fall in drug spendings. For drug spendings to be reduced, the policy such as reference pricing system could be considered as an option for the future.

Rapidly increasing pharmaceutical expenditure has been continuously challenging the sustainability of health insurance system. A major concern is the role of newly introduced drugs into the reimbursement list. What is the impact of those drugs on drug expenditures in Korea? This study aims to investigate their impact on the growth of drug expenditures by looking at the substitutability of the new expensive drugs for lower priced existing drugs. We termed such a substitutability as ``drug mix``. Using NHI claims data of four therapeutic classes (TC); Hepatitis, Diabetes, Overactive bladder(OAB), Migraine, pharmaceutical spendings of 2009 were compared with those of 2006. Each TC is characterized by different levels of new drug adoption. Growth of drug expenditures was decomposed into three parts; price effect, quantity effect and drug mix effect. The results are the followings. Impact of new drugs on the growth of drug expenditures for each TC between 2006 and 2009 ranges 0%~32%. Since new drugs were rarely introduced into TC of Migraine, its impact was negligible. Drug mix effect of newly introduced drugs in all TCs was positive, except OAB. Positive drug mix implies that lower cost existing drugs had been substituted for higher cost new drugs during the period under study. The quantity effect was positive for all TCs with increasing rate of 1%~52%. This positive quantity effect implies that the demand induced by new drugs was greater than that of the incumbent drugs. An exception to the above results is TC of OAB, with the negative drug mix effect, however with the positive quantity effect. In this case, the quantity of consumption grew. But with the introduction of lower priced new products coupled with the substitution of new products for the existing drugs, drug mix effect of new drugs was contributed to the savings of drug expenditure for OAB during the two periods, 2006 and 2009. This study is unique in its use of drug mix effect in estimating the impact of newly introduced drugs on drug expenditure. Through it, we could observe how old drugs are substituted for newly introduced drugs, and see its effect on the growth of drug expenditure. The methodology is unique and the results are rather informative for both researchers and policy makers.

Orphan drugs to treat rare diseases constitute a unique market structure, with strong monopoly at the producer side. The various characteristics embedded with orphan drugs create an environment which often in conflict with health policy goals of a health care system. For example in Korea, conflicts between the orphan drug producers and the public insurer generated the problem of drug supply refusal in recent years. Facing this as a health policy issue, this study examines diverse aspects involved surrounding orphan drug pricing and supply in the Korean context. In particular, ultraorphan drugs, orphan drugs with higher need of patient protection from insurer perspective, are susceptible to breakdown of price negotiations. The end result of negotiation breakdown takes the form of supply refusal, due mainly to supplier`s dissatisfaction with the proposed reimbursement price by the insurer. Moreover, for the health system`s perspective, funding high priced ultraorphan drugs within a limited public insurance budget often implies a painful trade-off, that many patients with more common diseases may have to forego highly cost-beneficial treatments. Facing all kinds of social and economic issues involved, this study investigates related concerns with the pricing and supply of orphan drugs first, and then a number of health policy options are offered within the Korean public health context.

The skincare market has grown rapidly to such an extent that an esthetician is viewed as one of the most promising occupations for women, and it`s urgently required to make research on skincare service preference to provide more professional, tailored and satisfying services in response to diverse customer needs. The purpose of this study was to examine the use of skincare shops by customers needs and preference for skincare services in a bid to help improve the quality of skincare services. The purpose of this study is to offer basic data necessary for qualitatively reinforcing the service level in the skin-care filed by grasping the needs and preferences for service on skin-care salon in customers of using skin care. The subjects in this study were women who were selected from among female residents in Seoul and Gyeonggi province who were in their 20s to 40s. Out of 391 collected answer sheets, 371 ones were analyzed except for 20 incomplete ones. Statistical data on frequency and percentage were obtained, and x2(Chi-square) test and frequency were utilized. The findings of the study were as follows: First, concerning their needs skincare services, they preferred an appointment service to other additional services provided by skincare shops they currently used, and they were most dissatisfied with the environments of the shops. They valued auditory service the most while they were at the shops, and they wanted to receive nail-art service the most during waiting time. Second, concerning their preference for skincare services, the color green was most preferred as the interior color of skincare shops, and psychotherapy music was most favored as the type of music they listened to. They had the biggest liking for herb wellbeing tea as drink to eat at skincare shops, and lavender was the flavor they was most fond of at skincare shops. They needed hairdrying service the most after skincare, and considered the Internet-connection service most unnecessary. The largest group wanted skincare shops to be furnished with up-to-date facilities for self-body care. Given seeing through the above results, the skin-care businesses will need to proceed with developing the high-level service strategy by specifically grasping needs for services on customer satisfaction. And prolonged research efforts should be directed into offering specialized skincare services, promoting scientific and systematic marketing and bolstering customer management in order to let skincare shops take root in modern society.

미국과 영국 등 가족상담이 일찍 발달한 나라에서 전문 학회 및 상담 관련 연구자들의 적극적인 동참으로 가족상담사 핵심역량 연구가 진행된 것과 달리, 한국에서는 사회문화적 특성을 고려한 가족상담사의 핵심역량에 대한 논의나 연구가 이루어지지 못했다. 이 같은 배경에서 본 연구는 슈퍼비전에서 활용 가능한 한국 가족상담사의 핵심역량 문항을 전문가 델파이 연구를 통해 구성하고자 하였다. 이를 위해 가족상담사 핵심역량 관련 국외 선행연구를 참고하여 핵심역량의 기초적 문항들을 추출하였으며, 이후 한국 가족상담 슈퍼바이저 20명을 대상으로 2회에 걸친 델파이 설문조사를 실시하였다. 초기 설문지 문항은 4개 영역, 20개 하위영역, 74문항으로 구성되었다. 1차 조사 결과 나타난 전문가 패널의 정성적 피드백과 항목의 중요도에 대한 평균, 표준편차, 내용타당도 비율(CVR)에 따라 문항이 선정되고, 단어 및 개념 수정, 일부 항목 삭제 또는 2개 이상 항목의 통합이 이루어진 후 2차 조사가 진행되었다. 최종적으로 4개 영역(‘가족 사정’, ‘치료계획 및 사례관리’, ‘치료적 개입’, ‘전문 윤리’), 10개의 하위영역, 44개의 문항으로 슈퍼비전을 위한 가족상담사 핵심역량(KFC-CC) 문항이 재구성되어 제시되었다. 본 연구 결과에 기초하여 연구자는 한국 가족상담 슈퍼바이저들을 대상으로 한 델파이조사 결과의 독특한 측면을 논의하였으며, 가족상담 교육, 훈련 및 평가에서 핵심역량 문항의 활용 방안들을 제시하였다. Objectives: Unlike the United States and the United Kingdom, in Korea, there has been no discussion or research on the core competencies of family counselors considering socio-cultural characteristics. This study attempted to construct core competency items of Korean family counselors that can be used in supervision through expert Delphi research. Methods: To this end, basic questions of core competencies were extracted by referring to previous overseas studies related to core competencies of family counselors, and then a Delphi survey was conducted twice with 20 Korean family counseling supervisors. Results: The initial questionnaire consisted of four categories, 20 sub-domains, and 74 questions through extraction of common categories from previous studies. After investigating twice, the questionnaire was reorganized into four categories, 10 sub-domains, and 44 questions as its final form. Conclusions: The authors discussed some unique aspects of Delphi survey results of Korean supervisors and suggested several prospective uses of the core competencies.
