Three economic marine algae that have been used as food and carrageenan sources were collected from Korea during a survey of marine algal flora. They share the generic features of Hypnea, and three major clades supported by the sectional features were confirmed in a phylogenetic tree based on rbcL sequences. The first species, which belongs to a species group corresponding to the sect. Spinuligerae, nests in the same clade with Hypnea yamadae in a genetic distance of 0%. It is morphologically characterized by an entangled base, subcompressed or subterete to terete axes, somewhat percurrent main axis, irregularly alternately branching with wide angle, and rarely hooked spinous branchlets. The second one is also referred to the sect. Spinuligerae and formed the same clade as Hypnea cenomyce. The genetic distance between both sequences was calculated as 0.0-0.1%, which is considered to be intraspecific. This species is distinct by somewhat entangled thallus at the basal part, percurrent axis, short spine-like branchlets densely covering the axis, and medullary lenticular thickenings. The third alga, which forms a species group corresponding to the sect. Pulvinatae, nests in the same clade as Hypnea nidulans (no intraspecific divergence). It shows occasionally epiphytic habitat rather than epilithic habitat of low mat-forming growth and percurrent erect main axes with dense lateral branchlets. Based on these morphological and molecular data, the three Korean species are identified as H. yamadae, H. cenomyce, and H. nidulans. This is the first record of the Hypnea species in Korea.

We performed a taxonomic study on Korean Pacificincolidae (Bryozoa: Cheilostomata) with the materials collected from 39 localities(ports, intertidal and subtidal zones) in the coastal seas of South Korea from 1981 to 2020. Korean Mucronella perforata reported by Rho and Seo (1985) turned out to be not Pacificincola perforata, but Primavelans glabricollaris n. sp. based on morphological data. Pacificincola perforata, which was transferred from Mucronella perforata (Okada and Mawatari, 1937), is also added to the Korean fauna. This study is the first to use mitochondrial 16S rRNA gene sequences to study the family Paficincolidae. The NJ analysis also reconfirmed the validity of the genus Primavelans, established on the basis of the early astogeny by De Blauwe in 2006, with the mitochondrial 16S rRNA sequences. The inter-genetic distance among two species belong to the Pacificincolidae was in the range of 13.39±1.83 mm. Primavelans glabricollaris n. sp. is thus distinguished from Pacificincola perforata with both morphological and molecular data. A new species, Primavelans glabricollaris, and a new record, Pacificincola perforata from Korea are herein described in detail and illustrated by scanning electron microscopy.

This study was conducted to investigate nutrient and food choices in gastric cancer patients receiving Cisplatin after surgery. Ten patients were followed from the fist day of the first cycle to the last date of the 6th the cycle of the chemotherapy. The subjects kept daily self record of dietary intake and the period of nausea/vomiting during 6 cycles. Using Computer Aided Nutritional Analysis Program, the degree of Calorie, carbohydrate, protein, fat and fluid intakes according the chemotherapy period. The reseacher developed food intake rating scale, and then three dietitians analysed the oral intakes according to the type of foods. As the results of this study, during the chemotherapy cancer patients are intakes much fewer calorie, protein and fluids than recommended dietary allowance. Oral intake was worsen as treatment proceed. During the chemotherapy periods most of the patients choose fruits, vegitables, steam rice, porridge, yogurt and the beam soup to overcome nausea and vomiting. In order to promote oral intake for chemotherapy patients, the researcher strongly suggest that indiviual food preform should be considered.

The utilization of horticultural tools in Korea is historically viewed through limited materials. The garlic shown in the birth myth of the Korean nation appears to be the first record of horticultural foods. Only the fragmentary knowledge is available on the production and utilization of horticultural foods during the eras from Old Chosun to the Three States and the Unified Shilla. It seems that mutual exchange of horticultural foods between the Three States and neighbor countries was very active. Kinds of horticultural foods utilized were more variable in the era of Koryo dynasty. The situation on horticultural foods during Chosun dynasty is comparatively well known through published agricultural books and other literatures.

In this study, we developed an application that can efficiently store and manage food ingredients in refrigerators. Rather than purchasing a new smart refrigerator, a small 'pocket scanner' is inserted inside the refrigerator using an existing refrigerator to track the location of food entering and leaving the refrigerator to efficiently organize the refrigerator and save time searching for ingredients. In addition, since it can automatically record the distribution period and purchase date, it notifies users through an alarm when the distribution period expires or is shortly left. As for the research method, after discovering the needs of users through in-depth interviews, the reactions of users were investigated by adding functions that fit those needs. Users felt satisfied with managing food efficiently through the 'pocket scanner' attached to the refrigerator and answered that it was very economical because various smart functions could be used without changing to a smart refrigerator. In the next study, we will also examine the usability of the application through usability evaluation.

Food waste is an inverse measure of consumer acceptability of the food as served and hence a potential determinant of food qualify. The plate waste of patients was examined by a visual method at one hospital. Patients were asked to record after each item on their menu the amount consumed in quantitative terms: None, 1/4, l/2, 3/4, all. The survey showed that 65% of all patients surveyed left some of their food during hospitalization. Mean wastes for soups and meat side dishes were found to be larger than those for cooked meals and vegatable side dishes. At the same time, a questionnaire survey was used to determine the view of patients of key aspects of the hospital foodservice system. The majority of patients surveyed left their cooked meal because of low appetite, whereas patients indicated that Food is not tasty was the primary reason for leaving soups and other side dishes.'Satisfaction' scores were significantly correlated with the patients' age and appetite at the time.

BACKGROUND/OBJECTIVES: The Recaller app was developed to help individuals record their food intakes. This pilot study evaluated the usability of this new food picture application (app), which operates on a smartphone with an embedded camera and Internet capability. SUBJECTS/METHODS: Adults aged 19 to 28 years (23 males and 22 females) were assigned to use the Recaller app on six designated, nonconsecutive days in order to capture an image of each meal and snack before and after eating. The images were automatically time-stamped and uploaded by the app to the Recaller website. A trained nutritionist administered a 24-hour dietary recall interview 1 day after food images were taken. Participants' opinions of the Recaller app and its usability were determined by a follow-up survey. As an evaluation indicator of usability, the number of images taken was analyzed and multivariate Poisson regression used to model the factors determining the number of images sent. RESULTS: A total of 3,315 food images were uploaded throughout the study period. The median number of images taken per day was nine for males and 13 for females. The survey showed that the Recaller app was easy to use, and 50% of the participants would consider using the app daily. Predictors of a higher number of images were as follows: greater interval (hours) between the first and last food images sent, weekend, and female. CONCLUSIONS: The results of this pilot study provide valuable information for understanding the usability of the Recaller smartphone food picture app as well as other similarly designed apps. This study provides a model for assisting nutrition educators in their collection of food intake information by using tools available on smartphones. This innovative approach has the potential to improve recall of foods eaten and monitoring of dietary intake in nutritional studies.

During a survey of fungal diversity in different provinces of South Korea in 2017, a new fungal isolate was discovered. This fungal isolate was identified as Westerdykella reniformis, based on its morphological characteristics and phylogenetic analysis, using internal transcribed spacer (ITS) and 28S ribosomal DNA (28S rDNA) sequence data. To our knowledge, W. reniformis has not previously been reported in South Korea. Thus, in this study, we report a new record of a species from the Dothideomycetes class in Korea, and provide a detailed description with morphological illustrations.
