This study was conducted to compare the shoot development and fruit characteristics on fruit bearing branch (FBB) according to the fruiting level (FLs: FL-Low, -Middle, -High) of peach 'Cheonhong'. The number of shoots per FBB according to the FLs were most distributed in 1-2 (42%) of FL-Low, 1 (47%) of FL-Middle and 1 (42%) of FL-High. And fruit weight and soulable solide content were 210-270g (50%) and 10-12Brix (44%), 180-240g (60%) and 10-12Brix (59%), 180-240g (60%) and 11-13Brix (48%), respectively. In addition, only FL-High showed a linear regression correlation between fruit weight and number of shoots. And a linear regression equation of y=0.0126x+8.1857 (R²=0.1964, P≤0.01) is shown between the souble solid content (y) and the fruit weight (x).

This study was carried out to investigate the effect of artificial light sources with different light qualities on the growth and flowering characteristics of a herbaceous long-day plant, Petunia ${\times}$ hybrida Hort. Seedlings of petunia cultivar 'Madness Rose' were potted, acclimated for one week, and grown in a phytotron equipped with tube- and bulb-type fluorescent lamps (FL tube and bulb), tube-type white light-emitting diodes (LED tube), halogen lamps (HL), metal halide lamps (MH), and high pressure sodium lamps (HPS) for 10 weeks. The temperature, photoperiod, and photosynthetic photon flux density (PPFD) in the phytotron were $22{\pm}2^{\circ}C$, 16 h, and $25{\pm}2{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, respectively. Light sources combined with HL promoted stem elongation, and plant height and internode length decreased with increasing red to far-red (R:FR) ratio. FL tube + LED tube, HPS, and FL tube promoted branching, whereas plants grown under light sources combined with HL did not have any branches. Days to flowering (from longest to shortest) occurred as follows: FL tube + HL > FL tube + HL > MH > HPS = FL tube + FL bulb > FL tube + LED tube > LED tube > FL tube, indicating that reducing the R:FR ratio of the light sources promoted flowering. Only 20% of plants grown under an FL tube flowered, whereas under all other treatments, 100% of plants flowered. At 10 weeks after treatment, plants grown under HPS and MH had (cumulatively) 12 open flowers, and those grown under FL tube + FL bulb, LED tube, FL tube + LED tube, and HPS treatment had approximately seven flower buds. These results suggest that light sources with low R:FR ratios promote flowering and stem elongation in petunia, but they reduce its ornamental value due to overgrowth and poor branching.

Comparative studies regarding the nutritional status of 93 home-living elderly people taking free congregate lunch meals(FL) and 87 middle income class elderly people(MI) were performed in Taejon city. Data was obtained from questionaires, anthropometry and interviews for the 24-hour dietary recall of 2 nonconsecutive days during August, 1996. The average age for FL was 75.8 years. The monthly familly income for FL belonged to the low-income class. FL females had lower heights and weights than MI females. The average daily nutritional intake of both FL and MI were low, particularly in FL whose %RDA of energy was 68.5%, protein 65%, Ca 29.6%, Fe 50.8%, vitamin A 34.5%, vitamin E 30.5%, riboflavin 40.6%, vitamin C 76.9%. MI's %RDA of energy was 76.4%, protein 80.a2%, Ca 48.1%, Fe 78.6%, vitamin A 67.3%, vitamin E 117.4%, riboflavin 45.6%, vitamin C 136.5%. Comsumption of Zn, vitamin $B_6$ and folic daily average. There was no nutrient having average INQ(Index of nutritional quality) over 1 for either group. The INQs for protein, Ca, Fe and vitamin A were 0.802, 0.377, 0.625 and 0.296 in FL, and 0.900, 0.601, 0.784 and 0.602 in MI, respectively. The MAR(Mean adequacy ratio) was low with the value of 0.500-0.518 in FL and 0.630-0.723 in MI. The percentage of main nutrients from lunch was the highest among the three meals for FL males, while that from breakfast was the highest for MI. Free lunches taken by FL supported higher percentages of main nutrients than home-lunches taken by MI. Eating-out was done more frequently by MI than by FL and that eating-out brought them more nutritional intake. The above data indicated that the dietary nutritional intake status of the FL elderly was very poor in both quantity and quality and that free congregate lunch significantly contributed to the daily nutrient-intake for the FL elderly.

BACKGROUND/OBJECTIVES: Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status. SUBJECTS/METHODS: This study utilized the data from the Seoul Food Survey, a cross-sectional study employing representative samples of Seoul citizens. Data collection occurred from September to October 2021, with 4,039 citizens aged 18 yrs and above participating in face-to-face surveys. Thirty-three FL items were assessed, comprising 14 items in the nutrition and safety (NS) domain, eight items in the cultural and relational (CR) domain, and 11 items in the socio-ecological (SE) domain. In addition, data on food intake sufficiency and obesity status were collected. The descriptive statistics, t-tests, analysis of variance, and logistic regression analysis were used for analysis. RESULTS: Men, students, young adults, older citizens, and people experiencing food insecurity had the lowest scores for all the FL domains. The highest quartile group of NS scores had a higher probability of consuming adequate servings of vegetables and fruits, with significant linear trends observed (P for trend < 0.05). In all three FL domains, the odds ratio for obesity was significantly lower in the groups with high FL scores (P < 0.05). CONCLUSIONS: A close relationship was observed between low FL, obesity, and food intake, even after controlling for other covariates. Vulnerable groups with low FL were also identified. Therefore, it is essential to develop programs to improve FL and the health and well-being of these groups.

The age and growth of the skipjack tuna Katsuwonus pelamis were determined using otoliths sampled from a Korean tuna purse seine fishery in the Western and Central Pacific Ocean from January 2005 to September 2006. A total of 312 otoliths were used to estimate the ages of skipjack tuna, which ranged from 1 to 7 years. The relationships between otolith ring radius (R) and fork length (FL) for female, male, and sex combined were FL = 19.74R + 1.50 ($r^2=0.54$), FL = 17.66R + 6.35 ($r^2=0.47$), and FL = 18.83R + 3.36 ($r^2=0.53$), respectively. The back-calculated fork lengths of each age ($FL_{year}$) were $FL_1=36.2cm$, $FL_2=43.3cm$, $FL_3=48.3cm$, $FL_4=52.6cm$, $FL_5=56.5cm$, $FL_6=60.8cm$, and $FL_7=63.2cm$. The relationships between fork length (FL) and total weight (TW) for female, male, and sex combined were $TW=0.00001FL^{3.19}(r^2=0.95)$, $TW=0.00001FL^{3.17}(r^2=0.95)$, and $TW=0.000009FL^{3.23}(r^2=0.95)$, respectively. The von Bertalanffy growth parameters of skipjack tuna estimated in this study were $L_{\infty}=77.4cm$, K = 0.176/year, and $t_0=-2.569years$.

Objective: To investigate the treatment effect of additional information obtained by single photon emission computed tomography (SPECT) lung perfusion imaging (LPI) in the radiotherapy planning process for patients with stage III non-small cell lung cancer (NSCLC). Methods: 39 patients with stage III NSCLC were enrolled. Gross tumor volume (GTV) was outlined by SPECT/CT images, SPECT-LPIs being used to define functional lung (FL) and non-functional lung (NFL) regions. Two sets of IMRT plans were designed to deliver 64Gy to PTV. One was a regular IMRT plan using CT images only (Plan 1), and the other was a corresponding IMRT plan using co-registered images (Plan 2). $FL_{Vx}$ (the % volume of functional lung receiving ${\geq}$x Gy) and $WL_{Vx}$ (% volume of whole lung to receive ${\geq}$x Gy) were compared by paired Student's t test. Kendalls correlation was used to analyze the factor (s) related with the FLV20 decrease. Results: Compared with plan 1, both $WL_{Vx}$ and $FL_{Vx}$ were decreased in plan 2. $WL_{V10}$, $WL_{V15}$, $WL_{V20}$, $WL_{V25}$, $WL_{V30}$ and $WL_{V35}$ decreased 9.7%, 13.8%, 17.2%, 12.9%, 9.8% and 9.8%, and $FL_{V10}$, $FL_{V15}$, $FL_{V20}$, $FL_{V25}$, $FL_{V30}$ and $FL_{V35}$ decreased 10.8%, 14.6%, 17.3%, 14.5%, 14.5% and 10.5%. $FL_{Vx}$ decreased significantly compared with $WL_{Vx}$. There were significant differences in $WL_{V10}$, $WL_{V15}$, $WL_{V20}$, $WL_{V25}$, $WL_{V3}$ and $FL_{V10}$, $FL_{V15}$, $FL_{V20}$, $FL_{V25}$, $FL_{V30}$ between plan 1 and plan 2 (P=0.002, 0.000, 0.000, 0.005, 0.027 and 0.002, 0.000, 0.000, 0.006, 0.010). According to Kendall correlation analysis, NFL had a negative relation with the percentage FLV20 decrease (r=-0.559, P<0.01), while the distance of PTV and NFL center had a significantly positive relation with the percentage of FLV20 decrease (r=0.768, P<0.01). Conclusion: Routine use of SPECT-LPI for patients undergoing radiotherapy planning for stage III NSCLC appears warranted.

2'-fucosyllactose (2'-FL) is the most abundant human milk oligosaccharide (HMO) present in breast milk, promoting the growth of beneficial microorganisms in the gut and aiding in the relief of allergic and inflammatory reactions. In this study, the anti-melanogenic effects of 2'-FL, and its potential for application in whitening cosmetics, were evaluated. MTT assay was performed on MNT-1 cells, human-derived melanocytes. 2'-FL was treated and replaced at 48 h intervals for 7 days, and it was confirmed that there was no cytotoxicity at 20 g/L or less, while a 40% reduction in melanin production was also observed. Western blot analysis of TYR and TYRP1, factors involved in melanogenesis, revealed that 2'-FL treatment reduced their expression levels. In addition, 2'-FL application and observation of the autophagy marker microtubule-associated protein 1 light chain 3 (LC3) revealed it was converted from LC3-I to LC3-𝚷, indicating increased autophagy. Likewise, confocal microscopy revealed an increase in LC3 puncta after 2'-FL treatment. Therefore, it is suggested that 2'-FL-mediated activation of autophagy reduces melanogenesis by inhibiting the expression levels of TYR and TYRP1 proteins. In conclusion, it has been confirmed that 2'-FL induces autophagy and suppresses melanin production, so its potential as a whitening cosmetic material is expected.

Despite the noteworthy increase in the number of FL anxiety studies, inconsistencies associated with the effects of FL anxiety on language learner performance have been reported in literature. Such conflicting results seem to be attributable in part to unstable conceptualization of the FL anxiety construct and its measure. This paper purported to address the emerging call for a theoretical clarification of the construct at hand as a preface to a clear picture of language anxiety on a conceptual ground. This paper not only covers aspects of general anxiety from psychological perspectives, but examines how FL anxiety and its associated concepts have been conceptualized in the literature. Inconsistent results that pertain to FL learning were also delineated. Given the drawbacks found in the exiting theories of FL anxiety, several points were taken into account for a refinement of the conceptual framework. This attempt will hopefully shed new light on the construct per se and prove conducive to the development of the field of English education.

The quantum efficiencies of CRT and FL tubes that use a phosphor screen as transducer of invisible particles to light in visible spectrum wavelengths were calculated in this study. The phosphor screens in CRT tubes have quantum efficiencies greater than 3,000, which give the luminance of comfortable images on phosphor devices for the observation by the eyes. The established FL tubes have the amazing quantum efficiency of $3{\times}10^{10}$ photons per moving electron per FL tube, which allows the illumination of a $5{\times}5\;m^2$ room by three FL tubes, with heating at $40^{\circ}C$. Thus, FL tubes, including for backlighting of LCD displays, have a superior over other illumination sources.

This study aims to estimate the smallest size of mature individuals that can be exploited. Fish samples of Coryphaena hippurus were collected from Kalinaun fishermen's catches in the Molucca Sea. They were sexed, then the fork length (FL) and maturity stage were recorded. Results showed that C. hippurus in the Molucca Sea had a sex ratio of 1:1.94 (p < 0.05). Males had a length range of 499-831 mm FL and females were in the length range of 481-813 mm FL. Size at first maturity was estimated as 529 mm FL for males with a range of 475-588 mm FL and 405 mm FL for females. This study provided basic information for future management needs of the dolphinfish, especially in the Molucca Sea.
