Before 1970, mandibular overgrowth was known as main cause of skeletal Class III malocclusion in growing children ; however, recent study reports that many skeletal Class III malocclusion patients also show maxillary deficiency. Since 1972, when Delaire re-accommodated Protraction Head Gear (P.H.G.), many researchers have reported that skeletal Class III discrepancies could be corrected through use of P.H.G., which induces anterior movement of maxilla and change in mandibular growth pattern into infero-posterior direction ; nevertheless, it is very difficult to predict resultant changes of orofacial region. The purpose of this study was to find out what treatment effect P.H.G. has on different study samples. Author divided 51 skeletal Class III malocclusion patients with maxillary deficiency who were treated with P.H.G. into different study groups depending on sex, treatment beginning age, intraoral appliance, and facial growth pattern. By doing so, following results were obtained. 1. Treatment beginning age and Sex Four age groups (5.8 to 8 year-old, 8 to 10 year-old, 10 to 12 year-old, 12 to 14 year-old) were compared, and no significant difference was observed. (p<0.05) There was no significant difference between the sex groups, either. (p<0.05). 2. Intraoral appliance Treatment effects of study groups that used R.P.E.(mean age of 10.2) and Labio-Lingual appliance(mean age of 8.9) were compared. There was no significant difference depending on the type of intraoral appliance that was used. (p<0.05) 3. Facial growth pattern 1) Amounts of SNB and ANB corrections were smaller in clockwise growth pattern group than those in normal or counterclockwise growth pattern group. (p<0.05) 2) Amounts of increase in Wits appraisal and mandibular plane angle were greater in counterclockwise growth pattern group than those in normal or clockwise growth pattern group. (p<0.05) 3)Amounts of increase in articular angle were greater in counter lockwise growth pattern group than those in clockwise growth pattern group. (p<0.05)

외교관계에 있어서 외교관의 특권ㆍ면제의 일고찰

Various fields of international law are always on the dynamic track of change. The development of international law is mainly triggered by the rapid, sometimes unexpected change of international realities. The development of international law on human rights, economic relations, democratic governance, use of force, and environmental issues is the best example for reflecting and echoing the movement of international law. Although it is reflected by new realities and challenges in international relations, international law on diplomatic relations, specifically international law on privileges and immunities of diplomats, seems to maintain its original form, contents and status in the pantheon of international law. Under the impact of globalization on international relations, the role of diplomats becomes more complicated and multifaceted. For the purpose of facilitating the activities of diplomats, privileges and immunities of diplomats should be respected by both international law and domestic law of every State. Also, privileges and immunities of diplomats should be enjoyed within scope of international law on diplomatic relations. Put it differently, the most critical thing is how to find out the middle path for striking the balance between the respecting the domestic laws and regulations of receiving State and the independence of diplomats’ activities of sending State. This article explores various aspects of international law on diplomatic relations. For example, difference between state immunity and diplomatic immunity, inviolability of the mission premises, personal inviolability, immunity from jurisdiction, immunity from execution, diplomatic bag, waiver of immunity, and duties of the mission towards the receiving State are analyzed in detail with relevant case study. Reviewing the dynamics of law on the diplomatic relations, this article foresees the desirable direction of the development of law on diplomatic relations and suggests the best way to strike the balance between the mutual interests of sending State and receiving State.

Recently, the incidence of perinatally detected asymptomatic adrenal gland masses has increased because of widespread use of radiological diagnostic tools. However, optimal treatment of these masses has not been determined. The aim of this study is to elucidate the treatment guideline of perinatally diagnosed adrenal gland masses. The authors retrospectively reviewed the medical records of the 11 patients with asymptomatic adrenal gland mass, detected perinatally, between 1999 and 2004. Six cases were detected by prenatal ultrasound and 5 cases were incidentally detected by postnatal ultrasound. Six patients (surgery group) underwent mass excision. The pathologic diagnoses were neuroblastoma (n=4), adrenocortical adenoma (n=1) and adrenal pseudocyst (n=1). The indications for operation were suspicion of neuroblastoma (n=5) or absence of size decrease during observation (n=1). Three of the 5 suspicious cases of neuroblastoma and one case under observation were proven to be neuroblastoma. There was no surgical complication in the urgery group. All neuroblastoma patients have been well during the follow up period ($24.4{\pm}14.4$ month) without evidence of recurrence. Five cases (observation group) were closely observed because of the benign possibility or size decrease in follow up ultrasound. During the observation period ($39{\pm}21$ week), 4 cases showed complete spontaneous resolution and 1 case showed markedly decreased size of the mass but could not be followed up completely. Surgical resection of the perinatally diagnosed asymptomatic adrenal gland mass is a safe treatment method especially in case of suspicion of neuroblastoma, but closed observation can be applied.

본 연구는 색채 추천 시스템인 안드로이드 모바일 앱 디자인을 위한 머티리얼 디자인 컬러시스템(Material Design Color System)의 배색에 관한 연구로 머티리얼 디자인 컬러 시스템과 기존의 배색 방법, 색채 구성 등의 배색 시스템을 모바일앱에 적용시켜 비교해 보았다. 머티리얼 디자인 컬러시스템은 3 색 이상의 배색일 경우 일반적인 주조색, 보조색, 강조색의 배색을 위한 색상 구성과 다르며, 모바일 앱이라는 특징적인 배색 영역 또한 다른 양상을 보여 주었다. 머티리얼 디자인의 컬러 팔레트는 정해진 색상의 규칙적인 색조 단계를 자동으로 시스템화하여 색상 선택을 용이하게 하였지만, 강조색에 대한 선택 사항이 없어 강조색의 선택과 그에 따른 정확한 배색 방법에 대한 가이드라인이 필요하다.

The aim of this study was to examine the relationship between psychophysiological information (i.e., heart rate variability) and a subjective anxiety measure (i.e., CSAI-2) in athletic performance. Methods: Ten female basketball players in a professional league participated in this study, and their heart rate variability and anxiety were assessed a total of six times during five days. Results: In result, partial correlation with statistical significance were found between heart rate variability and somatic and cognitive anxiety. Somatic and cognitive anxiety were positively related to LF/HF, and the negative relationship was shown with RMSSD. Due to situations of game, the significant change in SDNN was found before and after the second game. Conclusion: These results imply applicability of heart rate variability in research and performance enhancement service on athletic performance, anxiety, and arousal.

Minimalism Design의 색채 감성에 관한 연구

황승현(Hwang, Seung-Hyun),이현진(Lee, Hyun-Jhin) 한국색채학회 2016 한국색채학회 논문집 Vol.30 No.3

Minimalism which had grafted practical attributes of Modernism onto a field of design has been used to mean the mode of visual expression in the design as a part of art movement since 1960. Especially, the minimalism design in products mostly seen in simple and neat in form through using basic, geometric elements to accentuate morphological characteristics. The object of this study is to figure out how consumers think and feel about the color of minimalism design by analyzing between the associative color sensitivity images that consumers assume and the color sensitivity images that consumer feel after seeing minimalism designed products. As the result of survey using SD(Semantic Differential) method, it is shown that customers picked grizzled colors as the most suitable color for minimalism design both when they made assumption of minimalism design based on thoughts of it as simple, chic, and casual and when they chose the color after seeing the actual image of product. Although sensitivity adjectives and colors in minimalism design scored high in same field regardless of witnessing actual product, for the associate colors, Vp(very pale) tone was chosen a lot more on the other hand, after they had seen the actual image of product Dgr(dark grayish) tone scored more, which make it possible to consider the wider range of color choice for minimalism product design. As the result of the study, we suggest novel range of color group of minimalism product according to user"s emotional decisions.
