Purpose: The purpose of this study is to compare the radiological results of fixation using the femoral neck system (FNS) and cannulated screw (CS) for treatment of femoral neck fractures. Materials and Methods: A retrospective study of patients with femoral neck fractures who underwent internal fixation and had follow-up of more than six months from 2010 to 2020 was conducted. A total of 87 patients were enrolled in the study. The FNS group included 20 patients and the CS group included 67 patients. Classification of fractures was performed according to Garden and Pauwels classification. Operation time, intraoperative blood loss, sliding distance of the implant, lateral soft tissue irritation caused by implants, and complications were evaluated. Results: The mean operation time was 40.30 minutes in the FNS group and 46.84 minutes in the CS group. The mean intraoperative bleeding volume was 51.25 mL in the FNS group and 72.16 mL in the CS group. Bone union was achieved in 18 patients in the FNS group (90.0%) and in 61 patients in the CS group (91.0%). The mean sliding distance of the implant was 4.06 mm in the FNS group and 3.92 mm in the CS group. No patients in the FNS group and 12 patients in the CS group complained of soft tissue irritation. Conclusion: A shorter operative time, less intraoperative bleeding, and less irritation of soft tissue were observed in the FNS group. FNS could be an alternative to CS for fixation of femoral neck fractures.

Purpose: The purpose of this study was to compare job satisfaction and nursing performance of nurses on fixed night shifts (FNS) and nurses working three shifts (W3S), to identify the environment of night work and recognition of the viability of the FNS system. Methods: The research was conducted with 106 nurses on FNS and 257 on W3S. The nurses had worked for 1 to 11 years at A hospital, Seoul. Results: Job satisfaction was significantly higher (t=-3.51, p< .001) for nurses on FNS. However, no significant difference was found for nursing performance (t=-1.019, p=.309) between the two groups. Both groups of nurses were mostly satisfied. Subjective fatigue scores (0 to 10 points) during the night for nurses on FNS (6.02) were lower than for W3S nurses (7.28) A high percentage (88.7%) of nurses on FNS indicated a willingness to further participate in FNS. Conclusion: Results indicate that the demonstration FNS system showed its effectiveness. Therefore, efforts are needed to enhance and revitalize FNS and to upgrade the system to control patient transfer time from emergency departments to wards, and to provide nurses needed resources for emergency or intensive care.

Flavones are synthesized from flavanones through the action of flavone synthases (FNSs). There are two FNSs, FNS I and II. FNS I is a soluble dioxygenase present in members of the Apiaceae family and FNS II is a membrane bound cytochrome P450 enzyme that has been identified in numerous plant species. In this study, we cloned OsFNS I-1 from rice by RTPCR, expressed it in E. coli, and purified the recombinant protein. By NMR analysis, we found that OsFNS I-1 converted the flavanone (2S)-naringenin into the flavone, apigenin. Moreover, we found that the cofactors oxoglutarate, $FeSO_4$, ascorbate and catalase are required for this reaction. OsFNS I-1 encodes a flavone synthase I. This is the first type I FNS I found outside of the Apiaceae family.

The purpose of the study is to evaluate engineering properties of Ferro Nickel Slag (FNS) and to investigate the effects of FNS on potential contamination of surrounding soil and water through small and large chamber tests. Soil conditions in the chamber tests were made as closely as possibile to the field conditions. In order to simulate different types of water, we used fresh water, acidic water and seawater. Sand soils were made with relative densities of 40% and 60%, and clay with the degree of compaction of 90%. After flushing water through the FNS in the chambers was completed, the PH test was performed for the water flowing out of the chambers and the soil samples were collected for soil pollution analysis. Based on the results of the chamber tests, although the pollution level was slightly higher in the silt than in the sand, the environmental effect that FNS causes the surrounding soil was found to be very minimal. This indicates that FNS can be used as construction material in place of natural aggregates.

Background and Objectives: Facial nerve stimulation (FNS) is a complication of cochlear implantation (CI). This study compared the thickness and density of the bone separating the upper basal turn of the cochlea (UBTC) and the labyrinthine segment of the facial nerve (LSFN) on preoperative computed tomography (CT) in patients with and without FNS after CI. Subjects and Methods: Adult patients who underwent CI from January 2011 to February 2017 with preoperative CT at a tertiary referral hospital were considered for this retrospective case-control study. Patients were divided into two groups: with FNS (n=4) and without FNS (n=53). The density and thickness of the bone between the LSFN and UBTC were measured on preoperative CT. Charts were reviewed for other parameters. Results: A statistically significant difference was seen in the thickness (p=0.007) but not in the density (p=0.125) of the bone between the UBTC and LSFN. Four patients had FNS at the mid-range electrode arrays, and one of them additionally had FNS at the basal arrays. Conclusions: Decreased thickness of the bone between the UBTC and LSFN can explain postoperative FNS, confirming the histologic and radiologic findings in previous studies, which indicated that the thickness of the temporal bone between the LSFN and UBTC is less in patients who experience FNS. While the density in this region was also less, it was not statistically significant.

BACKGROUND: The ferronickel and rapid cooling slags used in present study are industrial wastes derived from a steel factory in Korea. These slags are used as almost road construction materials after magnetic separation. However, the use of slag to remove phosphorus from wastewater is still a relatively less explored. The objective of this work was to evaluate the feasibility of ferronickel slag (FNS) and rapid cooling slag (RCS) as sorbents for phosphorus removal in wastewater. METHODS AND RESULTS: Adsorption experiments were conducted to determine the adsorption characteristics of the FNS and RCS for the phosphorus. Adsorption behaviour of the phosphorus by the FNS and RCS was evaluated using both the Freundlich and Langmuir adsorption isotherm equations. FNS and RCS were divided into two sizes as effective sizes. Effective sizes of FNS and RCS were 0.5 and 2.5 mm, respectively. The adsorption capacities (K) of the phosphorus by the FNS and RCS were in the order of RCS 0.5 (0.5105) > RCS 2.5 (0.3572) ${\gg}$ FNS 2.5 (0.0545) ${\fallingdotseq}$ FNS 0.5 (0.0400) based on Freundlich adsorption isotherm. The maximum adsorption capacities (a; mg/kg) of the phosphorus determined by the Langmuir isotherms were in the order of RCS 0.5 (3,582 mg/kg) > RCS 2.5 (2,983 mg/kg) > FNS 0.5 (320 mg/kg) ${\fallingdotseq}$ FNS 2.5 (187 mg/kg). RCS 0.5 represented the best sorbent for the adsorption of phosphorus. In the experiment, the Langmuir model showed better fit with our data than the Freundlich model. CONCLUSION: This study indicate that the use of RCS in constructed wetlands or filter beds is a promising solution for phosphorus removal via adsorption and precipitation mechanisms.

This study analyzed the Food Neophobia Scale (FNS) and Korean food perception status of Southeast Asian workers living in South Korea in order to build up basic data to develop a desirable diet program. From our study, we found that FNS was higher in the order of Cambodian, Myanmar, Vietnamese, and Thai workers. Influential demographic factors for FNS were cooking possibility and place of residence. The mean scores of Cambodian workers ($3.46{\pm}0.63$) regarding "positive perception of cooking method, taste & color" about Korean food were the highest among the four countries, followed by Vietnam ($3.38{\pm}0.68$), Myanmar ($3.26{\pm}0.50$), Thailand ($3.09{\pm}0.64$)workers(p<0.01). The mean scores of Myanmar workers regarding perception of "difference in cooking method, smell & texture" and "difference in taste" were the highest among the four countries. FNS had a negative correlation with the factor "positive perception of cooking method, taste & color" regarding Korean food and a positive correlation with the factors "difference in cooking method, smell & texture".

Carbon dioxide emissions in the construction sector account for 38% of all industries, and environmental destruction is occurring due to indiscriminate use of natural resources. The purpose of this study is to develop by-product aggregate Non-Sintered Cement(NSC) that can replace sand used as natural aggregate and Portland cement. Therefore, Ground Granulated Blast Furnace Slag, Type C Fly Ash and Type F Fly Ash are used to replace cement, and water granulated ferro-nickel slag(FNS) is used to replace aggregate. The flow, compressive strength and flexural strength of the formulation using sand as an aggregate and the formulation replacing 100% FNS were compared. As a result of the experiment, the formulation using FNS had higher overall strength than the formulation using sand, and as the substitution rate of Type C fly ash increased, the strength was the best. Formulation using FNS is more fluid than using sand. Through this study, we show the possibility of 100% substitution of FNS and its applicability to secondary concrete products of by-product aggregate NSC.

An individual's food-related personal traits play an important role in influencing personal food choice and habits. According to culture, their influence can manifest differently. To ascertain personal traits about food, FNS (food neophobia scale) and FIS (food involvement scale) were employed in recent studies. This study aimed to understand the food culture and food choices of East-South Asians who live or stay in Korea through comparison of FNS and FIS. Eighty Koreans and 233 East-south Asians (Indonesians, Filipinos, Malaysians, Vietnamese, Thai, Singaporeans, and Bangladeshi) completed a questionnaire to measure FNS (10 questions), FIS (12 questions), and sociodemographic conditions (9 questions). ANOVA was conducted to ascertain FNS and FIS between the groups, and regression analysis was carried out to determine which sociodemographic factors had an effect. The items were analyzed to determine the differences according to gender, age, marital status, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. FNS showed significant differences between the groups with regard to sociodemographic characteristics, except gender, age, and marital status, whereas FIS showed significant differences in gender, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. The results of the regression analysis suggest that nationality strongly affected FNS and FIS, and FIS was also affected by gender.
