To meet the needs of societies that have been suggesting that practical competency is the key factor in the economies and societies of the 21st century, OECD developed the Program for the International Assessment of Adult Competencies (PIAAC). The purpose of this study is to critically review the contents of adult competency in PIAAC upon the premise that the validity of the contents of adult competency must be assessed before setting up any national strategies to develop adult competency. First, this study points out that the contents of adult competency in PIAAC seem insufficient to objectively measure cognitive and practical competency of adults. Second, the contents of adult competency in PIAAC assess only observable and measurable individual knowledge and functions, despite the fact that adult competency must be viewed as collective competency where various aspects of proficiencies are closely interconnected. Third, the contents of adult competency in PIAAC do not take the nature of humans into consideration: it assesses human beings based only on observable human behaviors. In conclusion, this study maintains that we need to discuss the adult competency that matches well with the societal and industrial needs of Korea and to critically review the validity of any measures assessing adult competency.

This study analyzed in nutrient contents changes of adult's favorite foods between March 2019 and July 2020 after policy implementation nutrient-poor foods based on special act on safety control of adult's dietary life in Korea. Among adult's favorite foods manufactured or sold in 2020 as well as 2019, calories and key nutrients in breads, ice creams and pizzas were improved in comparison to those in the other food groups. However, most of the changes in calories or key nutrient contents exist. The newly introduced candies, breads showed slightly greater improvements in calories and key nutrient contents than in 2019. On the other hand, some negative changes were found in newly introduced chocolates in comparison to previous ones. Overall, policy implementation on foods seemed to induce changes in nutrient contents of adult's favorite foods. In particular, nutrition education is reported to have a positive impact on adult's frequency and preference for processed foods, and more systematic and continuous nutrition education measures should be devised to help adult as consumers selectively purchase healthy foods. This research is meaningful in that it is the first study to analyze the quality changes of adult's favorite foods since the high-calorie and low-nutrient food management policy.

This paper is about adult certification on Mobile RFID Service Environments coming through the combination of RFID(Radio Frequency IDentification) technology, as the core technology of ubiquitous environments, and mobile telecommunication technology. To overcome the shortcoming of simple adult certification on current internet, we suggest a framework for content-based classification and propose an adult certification system using it. At first, we explain conventional methods for adult certification, and show a criteria of content-based classification for preventing an exposure of adult contents from minors. Additionally, we describe data structure and system for the proposed adult certification on mobile RFID environment, and finish it with concluding remarks.

현재까지 유해한 컨텐츠(Contents)를 차단하기 위한 활발한 연구가 있었으나, 사람의 음성(speech)정보를 이용한 필터링(filtering) 기법에 대한 연구는 활발히 이루어지지 않은 측면이 있다. 본 논문은 동영상 데이터를 가지고 있는 여러 데이터 중에서 음성 정보의 분석을 통하여 일반 컨텐츠와 성인 컨텐츠를 분류하기 위함이다. 본 논문은 음성 정보 중에서 음성 정보의 특징을 가장 잘 다루는 피치 검출을 통한 정보의 분석을 통한 성인 컨텐츠의 필터링에 그 목적이 있다. 현재까지 진행되고 있는 필터링(filtering)방법에 대한 수행 결과보다 개선된 성능을 보이고자 한다. 즉, 음성 정보의 특징 정보를 이용한 성인 컨텐츠(Adult Contents)분류 기법을 활용하는 것으로 성인 컨텐츠(Adult Contents)에서 두드러지는 특징을 보이는 사운드 패턴을 분석하는 것이다.

현재까지 유해한 컨텐츠(Contents)를 차단하기 위한 활발한 연구가 있었으나, 사람의 사운드(sound)와 이미지(image)를 통합한 필터링(filtering) 기법에 대한 연구는 활발히 이루어지지 않은 측면이 있다. 본 논문은 이미지(image) 데이터 중 피부색 분포 비율과 사운드(sound) 데이터 중 주파수 분석을 통한 심층적인 기법을 활용하여 현재까지 진행되고 있는 이미지 필터링(image filtering)방법에 대한 수행 결과보다 획기적으로 개선된 성능을 보이고자 한다. 즉, 사운드와 이미지의 특징 정보를 이용한 성인 컨텐츠(Adult Contents)분류 기법을 활용하는 것으로 성인 컨텐츠(Adult Contents)에서 두드러지는 특징을 보이는 사운드 패턴을 분석하여 현재까지 한정된 자원인 이미지만을 활용한 기법보다는 현저한 향상된 수행능력을 예측해 볼 수 있다.

This study was designed to investigate the effects of dietary protein and caffeine consumption levels on Ca, P, Na and K metabolism. One hundred twenty rats were divided into twelve groups according to age, protein level and caffeine consumption such as group(120-130g young rat, 250-300g adult rat) , dietary protein group (20% normal protein , 85 low protein) , caffeine consumption group(0, 3.5mg, 7.0mg). Low protein diet containing high caffeine levels caffeine levels increased calcium, phosphorus, sodium and potassium contents of urine and fecal in rats. Young rat has higher level of calcium, phosphorus , sodium and potassium than adult rat. In the serum, calcium contents were not affected by age, dietary protein levels and caffeine consumption . However, phosphorus, sodium and potassium contents of serum in adult rat were higher than young rat. In the liver, potassium decreased with decreasing dietary protein levels. In the kidney, calcium , phosphorus and potassium contents were not different by age group, dietary protein levels and caffeine consumption , but sodium content was significantly reduced in the adult rat.

The purpose of this study was to investigate differences of Ca, Mg and Zn utilization in young and adult rats fed standard diet for 3 weeks. Feed intake and body weight gain in young rats were significantly higher than in adult. There were no significant differences in serum levels of Ca and Zn across age and sex. In liver of young or male groups, Ca and Zn contents were significantly higher than in adult or female. There were no significant differences in tibia contents of Ca and Mg, but Zn content was increased when young or female groups was compared with the other groups. In mineral balances, daily intakes and retentions of Ca, Mg and Zn in young or male groups were significantly higher than those in adult or female. According to this results, it could be suggested that in growth period must be increased dietary intake of Ca, Mg and Zn to compromise the requirement for growth.

To classifying and filtering of adult images, in recent the computer vision techniques are actively investigated because rapidly increase for the amount of adult images accessible on the Internet. In this paper, we investigate and develop the tool filtering of adult images using skin color model. The tool is consisting of two steps. In the first step, we use a skin color classifier to extract skin color regions from an image. In the nest step, we use a region feature classifier to determine whether an image is an adult image or not an adult image depending on extracted skin color regions. Using histogram color model, a skin color classifier is trained for RGB color values of adult images and not adult images. Using SVM, a region feature classifier is trained for skin color ratio on 29 regions of adult images. Experimental results show that suggested classifier achieve a detection rate of 92.80% with 6.73% false positives.

The purpose of this study is to explore whether reading picturebooks portraying children's play assists adult readers to recall their childhood play memories according to the narrative model of human development. In this study, adult readers recalled their play memories before and after reading a picturebook depicting children's play. Adult readers' responses to the picturebooks were also collected. The types of play from their memories were categorized and the responses were qualitatively analyzed through open coding. The results indicated that first, before reading picturebooks portraying children's play, the type of play that adult readers mostly recalled was games with rules which happened outdoor. Second, after reading a picturebook, adult readers recalled new play memories which contained more detailed elements of narratives. Third, most adult readers responded to picturebooks either emotionally or aesthetically. This study suggests the perspective on picturebooks as a literature and art genre for readers from birth to death. In addition, as an evocative object, a picturebooks could assist adult readers to recall and rediscover their childhood.
