This study is to investigate that population change as a result of the decline in population has a correlation with a decrease in crime, with the change in the demographic composition by comparing with two models: model with growth in population and one with the decline in population. We collected demographic data for all cities in Korea from the 2010 Census to 2020 offered by the Korean Statistical Information Service, with crime data comprising serious reported crime events from the Korean Nation Police Agency through requesting data related to the total number of crimes at the same as the period of demographic data. This study can identify the impacts of demographic changes as a result of population change on crime change through a comparative analysis between areas with population growth and ones with population decline. We can confirm that there are differences in determinants of crime between areas with population increase and one with population decrease from the analysis of the impact of demographic change as a result of population change on crime change.

본 연구에서는 전국82개 도시를 대상으로 도시쇠퇴의 정도와 쇠퇴가 진행되는 과정에 관성이 있는지 확인하고, 도시가 처해있는 상황에 따라 어떤 방식의 대응방향이 필요한지 고민하였다. 향후 도시가 계속 성장할 것인지 혹은 계속 쇠퇴 할 것인지, 성장세가 둔화되어 쇠퇴할 것인지, 쇠퇴하던 곳이 성장세로 돌아설 가능성이 있는지, 각 도시의 전개 방향에 실마리를 찾고자 했다. 분석기간은 2005년과 2010년이며, 년도 별로 산정된 복합쇠퇴지수에 나타난 도시쇠퇴의 변화, 쇠퇴의 관성에 대해 분석하였다. 그 결과 도시쇠퇴에 관성이 존재하는 것을 확인할 수 있었다. 일부 도시에서는 쇠퇴가 고착화 되는 것으로 보인다. 이러한 곳에서는 성장시대 도시계획 수단과 개념을 쇠퇴환경에 맞추어 사용할 수 있도록 변화 시켜야 한다. 도시쇠퇴를 바라보는 관점을 재정의 하고 쇠퇴로부터 발생하는 물리 환경의 변화를 적절히 관리하기 위한 방안 모색도 필요하다. 도시의 발전방향과 가능성에 대한 인식을 바꾸고, 공간정책의 틀도 이를 반영해 마련할 필요가 있다.

본 연구는 1981년부터 2019년까지 한국의 생산가능인구 1인당 실질 GDP 추세성장률을 추정하기 위해 추세성장률이 임의보행을 따르는 비관측요인모형을 사용한다. 추정 결과, 추세성장률은 외환위기를 극복하던 시기인 2000년 전후를 제외하고 1980년대 후반부터 2010년대 초반까지 지속해서 하락하였다. 추세성장회계를 통해 추세성장률 하락요인을 분석한 결과, 지속적인 추세성장률 하락은 노동생산성 둔화와 관련이 깊은 것으로 나타났다. 구체적으로 살펴보면, 1988년부터 1998년까지의 추세성장률 1차 하락기는 외환위기 이전부터 둔화되기 시작한 노동증강 총요소생산성에 가장 큰 영향을 받았다. 이러한 결과는 외환위기로 추세성장률이 하락했다는 가설과는 배치되는 것이다. 한편 부진한 투자는 2002년부터 2012년까지의 2차 하락기의 중요한 배경인 것으로 나타났다.

Korean footwear industry has experienced rapid growth and decline during last 30 years. The purpose of this paper is to analyse the main reason for the decline of Korean footwear industry by examining the process of technological learning which Korean footwear firms experienced during last 30 years of OEM. Before this analysis is done, innovation patterns of world footwear industry is sketched to compare with those of Korean footwear industry. On the basis of the analysis on the reasons for decline, I suggest some policy recommendations.

This paper investigates a link between the significant decline in the growth of domestic demand and the dampened ripple effects from the export sector in Korea since the East Asian financial crisis. The dampened ripple effects are closely linked to the changed investment behaviors of the Korean large-sized exporting firms since the crisis: they do not invest in their export earnings any more to create new industries; they tend to use more foreign value added contents for their exports and to increase outward direct investment by actively participating in global value chains. The paper also examines a link between the growth of domestic demand and the growth of household disposable income and presents reasons for the decline in the growth of household disposable income since the East Asian financial crisis.

Gindai (Pristipomoides zonatus) is one of six snappers in a management complex called the Deep 7 of the Hawaiian Islands. Little is known about its life history and a preliminary analysis of otolith thin sections indicated the species may exhibit moderate growth with a lifespan approaching 40 years. Preliminary age estimates from the previous study were reinvestigated using the same otolith sections in an attempt to validate those ages with bomb radiocarbon (¹⁴C) dating. From the misalignment of birth years for the otolith ¹⁴C measurements with regional references - the post-peak bomb ¹⁴C decline period - it was concluded that previous ages were inflated from overcounting of the earliest growth zone structure in otolith sections. The oldest gindai was re-aged to 26 years once the age reading was adjusted for early overcounting, 13 years younger than the original estimate of 39 years for this fish. In general, the earliest otolith growth of gindai was massive and complicated by numerous subannual checks. The approach of lumping the early growth structures was supported by the alignment of ¹⁴C measurements from otolith core material (first year of growth). The result was greater consistency of calculated birthdates with the ¹⁴C decline reference, along with minor offsets that may indicate age estimation was imprecise by a few years for some individuals. The revised von Bertalanffy growth function applied to the validated age-at-length estimates revealed more rapid growth (k = 0.378 cf. 0.113) and a lifespan of approximately 30 years. The findings presented here are a case study of how the bomb ¹⁴C decline period can be used as a tool in the refinement of age reading protocols.

수도권에서 보고된 리기다소나무 생장감소의 원인을 밝히기 위하여 33장소의 리기다소나무 숲에서 교목의 밀도, 수령 및 토양의 물리화학적 특성을 조사하였다. 토성을 제외하고 토양의 물리적 특성들은 도심지와 전원지에서 차가 없었다. 그러나 토양의 pH값, 염기포화도 및 염기성 양이온 함량은 전원지에 비해 도심지에서 낮았지만, 수용성 Al 함량과 S함량은 그 반대였다. 도심지의 토양산성화는 산성강하물에 의한 영향으로 해석된다. 다중회귀분석 결과, 수도권에서 리기다소나무 생장은 토양의 가비중<토양의 Al 함량<교목의 밀도<토양의 Mg 함량<수령의 순으로 영향이 컸다. 결론적으로 수도권에서 리기다소나무 생장의 감소는 1차적으로 토양산성화가 주요한 요인이었을 것으로 판단된다.

The LCD monitor market enjoyed rapid growth in 1999 but only experienced modest growth in 2000. It is now poised for rapid growth from 2001 to 2005 as prices and costs decline. Price reductions will enable LCD monitors to move beyond limited vertical markets and extend into the broader consumer markets. This article will examine the future outlook for LCD monitors and provide a growth forecast.

Purpose - There have been not enough studies on the ways customer Moment of Truth(MOT) activities are structured along with consumption chain and their influences as well as the relative influences of service quality at Moment of Truth on customer performance. Therefore, customer service needs needed at Moment of Truth may differ depending on whether these distribution services are at introduction-growth stages or maturity-decline stage already, but there is no study which illustrates this. Research design, data, and methodology - This study selects VoIP and IPTV as the household telecommunication and distribution services at introduction-growth stages as well as high speed internet and wire telephone as those at maturity-decline stages. Then it identifies which experiences that customers have at Moment of Truth by each service as well as the influences related to what the customers consider as important. Results - As the result of demonstration with the target of 858 respondents, customers' experiences and requests differ at Moment of Truth. For service quality, what takes the positive roles in customer performance includes corporeality and certainty for the services at introduction-growth stages as well as reliability, sympathy, and mutuality for those at maturity-decline stages. Conclusions - Implications of these results as well as further directions for study are suggested.

Purpose: The purpose of this study is to examine the growth and change process of Korean cosmetic market that has grown more than three times since 2000. It also examined how the growth and decline of the cosmetics brands are related to the change of the cosmetic distribution structure. Research methodology: This study tried to classify the change of the Korean cosmetics market into four stages based on the market sales information. It analyzed the sales information of Korean cosmetic companies and the relationship with the sales of the brands by distribution channel. Results: One-brand store channel had played a leading role in the market growth, and multi-brand stores have grown and a number of brands also grew through that channel since 2013. Since 2016, multi-brand stores have continued to grow and have dominated the market beyond one-brand store channel. Conclusions: The changes in sales of domestic cosmetics companies have been classified based on the distribution channel type in four stages: the emergence of one-brand store, the growth of one-brand store channel, the growth of multi-brand store channel, and the decline of one-brand store channel. In conclusion, multi-brand store channels have recently grown in the Korean cosmetics market, and this trend is expected to continue.
