In this paper, we would like to share our ongoing research on global population and demographic shifts and the corresponding need for diverse responses. As population growth varies worldwide, the pressing issue is the current global housing shortage. The USA alone lacks 4 million homes, underlining the urgency for new construction and renewal of existing. Our focus is primarily on new building processes, which must also incorporate elements of renewal for future sustainability. Our research addresses several key questions: How will roles for construction professionals change? What should be the primary goal of the design process? What types of technologies are currently available, and which aspects of the process can be enhanced with AI? A significant part of our study is exploring sustainable building methods that reduce embodied carbon and increase speed of construction. Our goal is to extend the transition from smart homes to cities, analyzing the evolution towards smart communities and cities. A critical aspect of our research is the 'kit of parts concept, involving prefabrication and modular construction. This approach is essential for both rebuilding and new projects, potentially lowering costs in manufacturing and design for long term. Lastly, we present a detailed comparison of the construction industry with manufacturing.

최근 고객들은 다양한 IT 채널을 이용해 의견을 자유롭게 표현할 수 있게 되었다. 이에 따라 기업은 고객들의 의견 중 특히 부정적인 의견을 효율적으로 관리하기 위해 큰 노력을 기울이고 있다. 기존의 연구들은 주로 고객의 불만 제기 횟수나 상담시간 등의 양적 데이터를 이용하여 고객 이탈 방지에 관해 연구하였으나, 고객이 실제로 언급한 불만 내용을 분석한 연구는 한정적이다. 따라서 본 연구는 고객 불만 데이터를 중심으로 고객 이탈에 영향을 주는 요인들을 알아보기 위해 이탈-항의 이론(Exit-voice theory)을 바탕으로 보안업체의 고객센터로 접수된 46,235명 고객의 268,364건의 상담내용을 양적인 측면뿐이 아니라 질적인 측면에서도 실증 분석하였다. 감성 분석 방법을 활용하여 상담내용의 감성값을 도출하고, 도출된 감성 사전을 이용해 고객의 만족 여부를 명시적으로 알기 어려운 상담내용의 고객 만족도를 예측하였다. 마지막으로 이 감성 값이 고객의 이탈에 미치는 영향을 로지스틱 회귀분석을 통해 분석하였다. 분석 결과 고객이 만족 여부를 명확히 응답하지 않은 경우에도 감성 분석을 이용해 계산된 각 감성값이 고객 이탈에 서로 다른 영향을 준다는 것을 알 수 있었다. 향후 본 연구에서 제시한 감성 분석을 통한 만족도 예측방법으로 고객의 숨은 의도를 효과적으로 파악하여 고객 불만 관리에 실무적으로 활용될 수 있을 것으로 기대한다.

BACKGROUND/OBJECTIVES: A growing body of research has indicated that night eating could be associated with poor diet quality and negative health outcomes. This study examined the nutritional aspects of night eating, its related factors, and the association between night eating and body weight among Korean adolescents. SUBJECTS/METHODS: This study analysed the data from a one day 24-hour dietary recall as well as a demographic survey of 1,738 Korean adolescents aged 12 to 18-years-old obtained from the 2010-2012 Korea National Health and Nutrition Examination Survey. 'Night eating' was defined as consuming 25% or more of one's daily energy intake between 21:00 and 06:00. Subjects complying with the preceding condition were classified as 'night eaters', whereas the rest were considered 'non-night eaters'. Logistic regression analysis examined factors related to night eating. Multiple linear regression analyses were used to examine the relationship between night eating and BMI z-scores, whereas multinomial logistic regression analysis was used to examine the relationship between night eating and weight status. RESULTS: About 21% of Korean adolescents appeared to be night eaters. Night eaters showed increased breakfast skipping (P = 0.001), higher energy intake from snacks (P < 0.001), greater proportion of energy intake from fat (P = 0.029), and lower Dietary Diversity Scores (P = 0.008) than non-night eaters. Male adolescents presented 1.9 times higher odds of being night eaters than females. Adolescents whose both parents were night eaters were 4.4 times as likely to be night eaters as those whose neither parents were. Female adolescents showed a significant relationship between night eating and BMI z-scores (${\beta}=0.28$, P = 0.004). However, night eating did not increase odds of being overweight or obese in adolescents. CONCLUSIONS: Night eating in Korean adolescents was related to undesirable dietary behaviours and low diet quality in general as well as higher BMI z-scores in females. Male gender and parental night eating appeared to be the factors that significantly increased odds of night eating. These results suggest that night eating should be considered when designing nutrition education or intervention programs targeting adolescents.

This study was to investigate the degree of the nurses' burden and the attitude on the terminal cancer patients, as well as the relationship between two variables using questionnaire. The non-randomized convenient samples were 252 nurses with the experiences in caring the terminal cancer patients more than 1year in 5 university hospitals in Seoul and Inchon city. The cross-sectional one time survey was conduced by using the modified questionnaires on the burden and the attitude on the terminal cancer patients at October, 2000. n SPSS for Window, the demographic information and the degree of the burden and the attitude of subjects were analyzed with descriptive statistics. Pearson correlation coefficiency was used to investigate the relationship between the degree of the burden and the attitude from subjects. The additional analysis were performed to examine the differences the degree of the burden and the attitude by the general characteristics of the nurses using t-test and ANOVA. The result was as follow: 1) The degree of the nurses' burden on the terminal cancer patients was the mean of 2.91 ranged from 2.08 to 3.96. 2) The degree of the nurses' attitude on the terminal cancer patients was the mean of 3.52 ranged from 1.83 to 4.68. 3) There was no significant relationship between the degree of the burden and the attitude on the terminal cancer patients(r=.08, p=.23). However, the burden and. the nursing environment among 4 aspects of the attitude showed a significantly positive relationship each other (r=.16, p=.01). 4) The degree of the nurses' burden was different by the nursing specialties (F=2.79, p=.03) and the professional perspectives on nursing(F=3.52, p=.02). 5) The degree of the nurses' attitude was different by the age(F=5.33, p=.01), the married status(t=3.93, p=.05), nursing specialties (F=7.42, p=.00), the amount clinical experience(F=2.85, p=.04), the job satisfaction (F=10.58, p=.00) and, the professional perspectives on nursing (F=6.30, p=.01).

Purpose: In this study, we performed a comparative analysis on the quality of life (QoL) in male and female chronic obstructive pulmonary disease (COPD) patients based on the 4th Korea National Health and Nutrition Examination Survey (KNHANES IV) from 2007 to 2010. Methods: We extracted the socio-demographic and clinical data of 1,218 COPD patients including 874 men and 344 women from the KNHANES IV database. Descriptive statistics and correlation test were used to analyze the data. In order to find factors associated with QoL of COPD patients, we conducted multivariate linear regression analysis. Results: Infrequency analysis, the educational level and income were lower in the female COPD patients than in the male ones. The QoL indexes including mobility, self-care, activities of daily living, discomfort, anxiety, and depression were significantly worse in the female of COPD patients than in the male ones (p<.01).Conclusion: Our study indicates that QoL of female COPD patients should be improved on the educational, economic, and healthcare aspects.

Background: Pain is one of the most important consequences of spinal cord injury (SCI). It may affect several aspects of life, especially the quality of life (QoL). Hence, this study was conducted to establish an understanding of pain and its correlates and effects on patients with SCI in our community. Methods: In a cross-sectional study, 58 male veterans suffering from SCI were admitted to our center for a regular follow-up. Demographic and SCI-related descriptive information were gathered using a self-reported questionnaire. To evaluate the patients' pain quality and the effect of pain on daily life, a questionnaire in 3 parts of lumbar, cervical and shoulder pain was administered. EuroQoL questionnaire and General Health Questionnaire (GHQ) 12 were also used to assess the patients' QoL. Results: The mean age of the participants was $45.91{\pm}6.69$ with mean injury time of $25.54{\pm}5.91$. forty-four patients (75.9%) reported pain, including lumbar pain (63%), cervical pain (39%) and shoulder pain (51%). The presence of pain was associated with lower QoL. Patients with lumbar pain reported a significant amount of pain affecting their daily life and this effect was higher in patients with lower GHQ score or anxiety/depressive disorder. Conclusions: Musculoskeletal pain, is a common complaint in veterans with SCI and is inversely associated with functioning and general health status. Lumbar and shoulder pain affects patient's daily living more than cervical pain.

The purpose of this study is to offer basic data to adolescents' cosmetic culture by investigating and analysing the choices made by female students who have been becoming principle consumers of cosmetics these days. Firstly, social and cultural backgrounds and concepts of N generation, and then characteristics and influencing powers of female students were reviewed. And this study also included questionnaire surveys of 500 female students in middle and high schools located in Seoul. Data were processed using a SPSS$^+$ program and analyzed by using frequency, percentage and the $X^2$-test. The major findings run as follows: Female students have the effects of spreading their words quickly and abilities of making a decision what to buy. And they accept consuming behaviors itself as a part of cultural lives. Therefore, industries have acknowledged them as new principal consumers with a powerful influence in the market. They also play an important role in active consumer as emotional generation who has distinct personalities and prefer fashion trends, changes and innovations. They show conformities with their peer groups and they also want to identify themselves with characters or stars. The cosmetic behaviors of female students relating to demographic characteristics showed a significant relation to grades, majors, school groups and places of residence. Female students have a lot of interest and knowledge about cosmetics. And they use various cosmetic products. This study demonstrated the age for using make-up for the first time has been becoming younger more and more. Recently, female adolescents tend to use face powder, lip gloss, mascara and eye shadow. It is assumed that cosmetic purchases of female students can be considered as an impulsive aspects. However, before purchases, the proportion of students having any particular cosmetic brand in mind previously has been increasing. They take into consideration skin safety, the quality of product and color, when purchasing cosmetic products.

Bioelectric impedance measurements have been reported to show significant variation between individuals. Different physiological conditions like thickened skin, obesity, and fluid retention can affect the impedance measurement. Therefore, it is important to learn what other factors can affect the measurements of impedance even in healthy individuals. Such information is a prerequisite for understanding the changes in impedance associated with acupuncture treatment. This study investigated the bio-impedance properties of tissue segments in the arms of a number of healthy subjects, so as to define the factors that might influence the variation of the bio-impedance data in acupuncture meridians studies. 51 healthy subjects were recruited through Liverpool Hospital, Sydney. Demographic data was collected from each subject including the age, sex, BMI, and time since most recent meal. Electrodes were applied to the forearms of each test subject. Measurements were done by a purpose-built Bio-Impedance Research Device (BIRD-I) which allowed the determination of core resistance (Rc) and core reactance (Xc) of each of the three meridian tissue segments on the anterior surface of the forearm. No significant difference was found in the core resistance attributable to age group, gender, BMI or meal intake. However, a statistically significant trend in increasing resistance from the radial to ulnar aspect of the forearm (p < 0.001) was found. No significant difference was found in the core resistance of test tissue segments among the 51 healthy subjects measured in this study. However, the trend of increasing core resistance from the radial to ulnar aspects of the arm deserves further investigation.
