The purpose of this study is to compare and analyze the perceptions of foreign learners and Korean language teachers on Korean culture education methods. The results derived through this seem to be meaningful in that basic data on Korean culture education can be obtained in the future. To justify this purpose, an online survey was conducted on 130 foreign learners and 28 Korean language teachers on their preferred learning methods for 12 major categories of Korean culture education published by the National Institute of Korean Language. As a result of the survey, two areas of history and science that foreign learners responded with insufficient learning experience were excluded. And among the remaining 10 areas, values, politics, economy, education, and society were the areas where learning methods generally coincide between learners and teachers. On the other hand, there were differences in life, customs, geography, art, and cultural heritage areas. These differences need to be actively reflected in the design of Korean culture education in the future.

Purpose This case follows the complications, treatment, and results of a 69 years old male patient who sustained complete right quadriceps tendon tear secondary to a fall. Due to cardiovascular complications, surgery was delayed for a month, and reconstructive surgery was extensive. Methods He was assessed as suffering from significantly decreased range of motion (ROM), decreased strength, and secondary, unilateral lymphedema. Physical therapy began 10 weeks post-surgery and consisted of a 3-month rehabilitation program to increase ROM, strength, and balance, as well as to reduce edema. Results Measures were assessed at initial evaluation and final discharge. Right knee Active Range of Motion (AROM) flexion increased from 60 to 86 degrees and extension improved from -26 to -15 degrees. Knee joint circumference was reduced from 49 cm to 45.4 cm. Lower Extremity Functional scale improved from 13/80 to 35/80. Timed Up and Go improved from 18 seconds with bilateral crutches to 7 seconds without crutches. Tandem balance progressed from less than 1 second to greater than 1 minute. Single Limb Stance from less than 1 second to 29 seconds on the right. Conclusion The case report describes the interventions status post delayed quadriceps tendon repair for an older adult that was effectively in improving AROM, functional mobility, and balance.

<P>In this letter, we propose a distributed interference alignment (DIA) technique in a two-cell multiple-input multiple-output (MIMO) network with dynamic time division duplex (TDD) mode under local channel state information assumption. The dynamic TDD operation introduces new types of interference, such as downlink-to-uplink [base station to base station (BS–BS)] and uplink-to-downlink [mobile station to mobile station (MS–MS)] interferences. Under the assumption of rank-deficient BS–BS MIMO interference channel, we mathematically characterize the achievable degrees-of-freedom of the proposed DIA technique for a given number of antennas at BS/MS. Through extensive computer simulations, it is shown that the proposed DIA technique outperforms the conventional techniques in terms of sum-rate at the cost of signaling overheads for the BS–BS and MS–MS channel overhearing.</P>

전북지역 밭 토양의 화학성 특성과 수용성 양분과의 관계를 조사하기 위해 도내 14개 시‧군의 밭토양 160지점을 선정하고, 대상 토양의 표토를 채취하여 토양 양분 함량을 조사하였다. 일반 화학성은 농촌진흥청 토양분석법에 따라 분석하였고, 수용성 양분은 토양과 증류수를 혼합하고 15시간 진탕한 다음 여과하여 분석하였다. 조사 대상지의 토양통은 47종으로, 이 중 송정통이 30지점으로 가장 많았으며, 토성별로는 양토와 사양토, 지형별로는 구릉지와 곡간지가 많았다. 토양의 평균 화학성은 pH 6.4, EC 0.98 dS/m, 유기물 25 g/kg으로 적정 범위에 분포하고 있었고, 유효인산 648 mg/kg, 교환성 K<SUP>+</SUP>와 Ca<SUP>2+</SUP>는 각각 1.1, 6.3 cmol<SUB>c</SUB>/kg으로 적정 범위보다 높은 수준이었다. 이를 4년 전 조사결과와 비교하면 EC, 유기물, 유효인산, 교환성 K+<SUP></SUP> 등에서는 밭토양 적정범위 내에 분포하는 토양 비율이 증가하였고, pH 7.0을 초과하는 비율은 증가한 반면, EC 2 dS/m과 교환성 K<SUP>+</SUP> 0.8 cmol<SUB>c</SUB>/kg을 초과하는 비율은 감소하는 특성을 보였다. 조사 지점의 수용성 양이 온 평균 함량은 K<SUP>+</SUP> 115 mg/kg, Ca<SUP>2+</SUP> 100 mg/kg, Mg<SUP>2+</SUP> 32.7 mg/kg, Na<SUP>+</SUP> 25.1 mg/kg로 일반 화학적 특성과 고도의 유의성을 보였고, 특히 수용성 K<SUP>+</SUP>는 교환성 K<SUP>+</SUP>와, 수용성 Ca<SUP>2+</SUP>와 Mg<SUP>2+</SUP>는 EC와, 수용성 Na<SUP>+</SUP>는 교환성 Na<SUP>+</SUP> 와의 상관계수가 가장 높았다. 수용성 음이온의 평균 농도는 NO₃<SUP>-</SUP> 233 mg/kg, SO₄<SUP>2-</SUP> 108 mg/kg, PO₄<SUP>3-</SUP> 77.5 mg/kg, Cl<SUP>-</SUP> 56.0 mg/kg, NO₂<SUP>-</SUP> 10.8 mg/kg 순으로 나타났으며 이 중, NO₃<SUP>-</SUP>, SO₄<SUP>2-</SUP>, Cl<SUP>-</SUP>, NO₂<SUP>-</SUP>은 EC와 가장 높은 정의 상관을, PO₄<SUP>3-</SUP>는 유효인산과 가장 높은 정의 상관을 보였다. 이에 따라 농경지 토양의 양분 기준과 관리가 일반 화학성뿐만 아니라 수용성 형태의 양분에 대해서도 이루어져야 할 것으로 판단되었다.

Objectives: The household secondary attack rate (SAR) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an important indicator for community transmission. This study aimed to characterize transmission by comparing household SARs and identifying risk factors during the periods of Delta and Omicron variant predominance in Republic of Korea.Methods: We defined the period of Delta variant predominance (Delta period) as July 25, 2021 to January 15, 2022, and the period of Omicron variant predominance (Omicron period) as February 7 to September 3, 2022. The number of index cases included was 214,229 for the Delta period and 5,521,393 for the Omicron period. To identify the household SARs and risk factors for each period, logistic regression was performed to determine the adjusted odds ratio (aOR).Results: The SAR was 35.2% for the Delta period and 43.1% for the Omicron period. The aOR of infection was higher in 2 groups, those aged 0 to 18 years and ≥75 years, compared to those aged 19 to 49 years. Unvaccinated individuals (vs. vaccinated individuals) and individuals experiencing initial infection (vs. individuals experiencing a second or third infection) had an increased risk of infection with SARS-CoV-2.Conclusion: This study analyzed the household SARs and risk factors. We hope that the results can help develop age-specific immunization plans and responses to reduce the SAR in preparation for emerging infectious diseases or potential new variants of SARS-CoV-2.
