Background: Standing biomass, litter production, rate of litter decomposition, amount of litter on forest floor, and amount of soil organic carbon distribution were investigated from March 2016 to November 2018 in order to evaluate the ecosystem value through organic carbon distribution in the Pinus densiflora forest at Namsan, Seoul Metropolitan City. Results: The amount of organic carbon in the Pinus densiflora forest was 261.09 ton C ha^-1 during the research period, and fixed organic carbon in plant through net photosynthesis was 3.2 ton C ha^-1 year^-1. The organic carbon in plant was 62.77 ton C ha^-1 (24.04%), in litter on the forest floor was 3.65 ton C ha^-1 (1.40%), and in soil was 194.67 ton C ha^-1 (74.56%). The value of plant, litter on forest floor, and soil organic carbon distribution were each 6,277,000 won ha^-1, 365, 000 won ha^-1, and 19,467,000 won ha^-1. The value per ton of fixed organic carbon in plant through net photosynthesis was 320,000 won ha^-1 year^-1 and the value of ecosystem services stored in carbon in the Namsan forest ecosystem was about 26.1 million won ha^-1 for 3 years. Conclusions: The results of this study suggest that the pine forests of Namsan rapidly decompose leaves due to the high atmospheric temperature and accumulate a large amount of organic carbon in the soil to provide climate control regulatory service function.

하정연,김은주 부산대학교 영유아보육연구소 2000 영유아보육연구 Vol.6 No.-

This program developed, implemented, and evaluated a "fingertip" handicraft program for early-childhood facilities. The program was conducted in one class of three-year-olds and two classes of five-year-olds of P child care center, from March to December, 2000. The program was implemented as two stages : a "preparation" stage (for 3~4 year-olds) and a "practice-and-deepening" stage (for 4~5 year-olds). The "fingertip activities" in the reparation stage of the program consisted of the following : transferring of small objects, clipping ㆍ folding ㆍ pasting ; using "clothing frames" ; and the basic stages of sewing. The activities in the practice-and-deepening stage consisted of the following : making cat's cradles, knitting, and doing embroidery. The program was evaluated positively by the children, teachers, and parents involved. The children developed the use of their fingertip muscles, power of concentration, and patience, as well as their capacity to recognize practical and artistic values, a sense of achievement, and the meaning of labor. By seeing positive changes in the children, the teachers realized that handicraft activities were beneficial. The parents of the children learned that "fingertip activities" were worthwhile at both school and at home, and they perceived a need for transferring traditional culture to younger generations through inter-generational interactions.

“Did You Enjoy Dining Alone?” An Examination of Solo Diners

Ha,Joo-Yeon,Park,Jeong-Yeol,Robin M,Back 한국식공간학회 2020 식공간연구 Vol.15 No.3

As the number of people spending time alone continues to increase, more people are engaging in solo consumption experiences, resulting in dining alone at a restaurant becoming more prevalent. Restaurants have responded in a number of ways to provide accommodations for solo diners’preferences, including the provision of different table layouts such as small tables, bar seating, and communal tables. However, a close examination on the impact of such table arrangements on solo diners’ behavioral intentions is lacking. This study was designed to examine the influence of table layouts, in conjunction with three restaurant quality dimensions (food quality, service quality, and atmospheric quality), on solo diners’ positive emotions and situational loneliness, which ultimately influences behavioral intentions. Structural equation modeling was used to analyze data collected from 286 United States residents who had dined alone at a restaurant within the previous two weeks. Results suggested that food quality and service quality stimulated positive emotions, while food quality decreased situational loneliness. Bar seating increased positive emotions and decreased loneliness. Positive emotions increased both revisit intentions in general and revisit intentions as a solo diner. Loneliness, on the other hand, was shown to decrease revisit intentions as a solo diner.

<P><B>Abstract</B></P> <P><B>Ethnopharmacological relevance</B></P> <P>Although <I>Spilanthes acmella</I> has been used to relieve inflammation, fever, pain, or infection in traditional Asian medicine, experimental evidence supporting these functions is scarce. Here, we examined an anti-inflammatory function and a possible underlying mechanism of <I>S. acmella</I> Murray (SAM).</P> <P><B>Materials and method</B></P> <P>The methanol extract of SAM was fingerprinted by HPLC. C57BL/6 mice were administered with a single intratracheal (i.t.) LPS and 2 h later with a single i.t. SAM. The effect of SAM on lung inflammation was assessed by histology, semi-quantitative RT-PCR, and MPO assay of lung tissue. The effects of SAM on a pro-inflammatory factor NF-κB and an anti-inflammatory factor Nrf2 were analyzed by immunoblotting of nuclear proteins and by semi-quantitative RT-PCR analysis of mRNA of the genes governed by these transcription factors. V5-Nrf2 was precipitated by an anti-V5 antibody and the ubiquitinated V5-Nrf2 was revealed by immunoblotting of HA-tagged ubiquitin.</P> <P><B>Results</B></P> <P>The i.t. SAM robustly diminished a neutrophilic lung inflammation induced by i.t. LPS treatment of mice. In RAW 264.7 cells, SAM suppressed the nuclear localization of NF-κB and the expression of NF-κB-dependent cytokine genes. SAM increased the level of Nrf2 in the nucleus and the expression of Nrf2-dependent genes while suppressing ubiquitination of Nrf2.</P> <P><B>Conclusion</B></P> <P>Our results suggest that SAM can suppress a neutrophilic inflammation in mouse lungs, which is associated with suppressed NF-κB and activated Nrf2.
