The elderly population in Korea is growing rapidly and their nutritional status is not acceptable. Data were collected from the self-administered questionnaire of 495 free living elderly, over 65years old, in Korea to asses the intake and consumption pattern of milk and dairy products. The questionnaire contains demographics, health related characteristics, and perception on milk, and consumption behaviors of milk and dairy products. Most of the elderly subjects understood that milk is good foods in terms of nutritive value and health. And 67% of the subjects satisfied with the sanitation status of milk on the markets. The kind of milk that majority of the subjects consumed was whole milk, and only 5.1% of them consumed low fat milk. Less than 20% of the subjects consumed milk everyday, living alone group consumed milk less frequently than living with others. It was found that the majority of the elderly subjects did not meet current recommendation for milk. Liquid and curd type yogurt were the major dairy products used among elderly, and the reasons were good taste and digestion.

Objectives: Most cohort studies used food frequency questionnaires (FFQ) to evaluate coffee consumption as it assesses habitual dietary patterns, whereas some studies have used the 24-hour recalls (24HR) as it elicits in-depth description of foods and the amount eaten. The aim of this study was to compare FFQs and 24HR to assess the consumption of various types of coffee. Methods: We included 25,904 participants aged 40 years or older from the Health Examinees (HEXA) Study of the Korean Genome and Epidemiologic Study (KoGES). Each participant completed one FFQ and one-day (n=11,280) or two-day 24HR (n=14,624). We classified coffee types into: black coffee, coffee with sugar and cream, and coffee with sugar alone or cream alone. We compared the proportions of nondrinkers, black coffee, and coffee with sugar and cream through FFQ and 24HR. Results: Among those who completed one FFQ and one-day 24HR, 39.4% of "nondrinkers" on one-day 24HR reported that they did not drink coffee on their FFQs. Whereas among those who complete two-day 24HR, 71.2% of "nondrinkers" on two-day 24HR said that they did not drink coffee on their FFQs. Among those who completed one FFQ and oneday 24HR, 58.3% marked "black coffee" on one-day 24HR said that they drank black coffee on their FFQs. Among those who complete two-day 24HR, 58.8% marked "black coffee" on two-day 24HR said that they drank black coffee on their FFQs. The kappa coefficients and percent agreements were 0.4 and 59.6%, respectively, for the comparison of coffee intake between FFQ and one-day 24HR, and 0.6 and 72.8%, respectively, for the comparison of coffee intake between FFQ and two-day 24HR. Conclusions: We found discrepancies between FFQs and 24HR in the types of coffee consumed. Such limitations should be considered when using the 24HR data to examine the effect of coffee consumption on disease development.

This study focuses on apparel production and consumption trends in major Asian economies in order to understand a paradigm change in the Asian fashion industry. A comparison of trade among ASEAN, NICs, and developed countries shows the changes that have occurred in terms of production and consumption of fashion products before and after 2000 in Korea, Hong Kong, and China. The flow of imports and exports in the apparel industry was analyzed using UN trade statistics data. The results found a change of industry structures in Asian NICs and ASEAN countries. Garment production bases have moved to lower cost regions like China and ASEAN; in addition, NICs sent a part of their export business in the fashion industry to ASEAN countries. The Asian fashion industry has transformed from a production base for developed countries into a consumption market with the emergence of newly industrializing economies.

In this paper, we propose a design of microwave motion detector using X-band doppler radar sensor to minimize the power consumption. To minimize the power consumption and implement battery operated system, pulse input with 2 KHz, 4% duty cycle is exerted on the doppler radar sensor. In order to simplify the process of working with ATmega2560 microcontroller unit, Arduino compatible board is designed and implemented. Arduino is open source hardware and many library software is published as open source tools. Smartphone app is also proposed and designed as a real-time user interface of the motion detector. The SQLite database on the Android mobile operating system is used for recording raw data of motion detection for post-processing job, such as fast Fourier transform (FFT). Bluetooth interface module is implemented on the motion detection board as a wireless communication interface to the smartphone. The speed of human movement is identified by post-processing FFT.
