We have reported novel solid-cancer treatment modality of nano-thermal ablation therapy using two medical devices of 100kHz electromagnetic field radiator and heat-generating nanoparticles of MCL particle [1]. External 100kHz electromagnetic field radiation induced heat generation of MCL particle in tumor tissue and caused tumor specific cytotoxicity and blood vessel disruption [1]. MCL particle was designed to be about 100nm diameter and to move within tumor tissue by composing heat-generating magnetite (Fe<SUB>3</SUB>O<SUB>4</SUB>) with neutral and cationic lipids [1]. However, concerning 100kHz radiator, rational concept of its performance and specification was not fully discussed. Purpose of this seminar is to describe significance of 100kHz magnetic flux density for rational designing, specification and usage of the radiator, referring to our unpublished data during 2004~2025. At first, our calibration method of 100kHz magnetic flux density was shown, and then its application to density distribution analysis of our radiators HTS-5010H and Hi-Heater 5010 was described. And, based on density distribution profile of Hi-Heater 5010 radiator, effective density at tumor locus in the standard treatment condition of the therapy was confirmed 15mT. Based on the recorded data of clinical research using HTS-5010H radiator, safety radiation condition toward groin, breast, thigh, neck, chest and arm were shown with density distribution in patient bodies. With all respect, quoting MFH<SUP>®</SUP>300F (100kHz) radiator [2], availability of three types radiators for various target cancers was discussed on the basis of effective tumor density and mitigation of normal tissue heating. According to Design Control Guidance of medical device [3], design process of the radiator was exemplified by drafted documents of design input and output.

This study is aimed at examining the prevalence of premarital sex among adolescents between 13-19 years within Chorkor, Korle Gonno and Mamprobi communities in the Accra Metropolis. The study with a sample size of 268 used a descriptive approach and a combination of convenient and quota sampling methods. The study recommends the establishment of a school guidance and counselling unit to sensitize and advise students and parental monitoring of adolescent lives and the use of social media on mobile devices.

Ill-discipline has become a canker that threatens the moral fibre of institutions. This study aimed to explore the comprehensive counselling approaches that could be used to manage ill-discipline acts in Colleges of Education in Ghana. A qualitative discourse analysis study design was employed in the study. In all, 25 respondents were purposively selected from five colleges of education for the study using a semi-structured interview guide. Data collected were transcribed, coded, categorised and qualitatively analysed under themes that emerged from the analysis using the thematic approach. The study revealed that several ill-discipline acts exist in colleges of education, with perversion being the most prevailing ill-discipline act. The study recommended that the college council and management should put adequate measures in place to strengthen Guidance and Counselling units in the colleges of education. The study also recommended that college counsellors should be equipped to use appropriate counselling approaches and techniques to counsel students to desist from indulging in ill-discipline acts.

The purpose of this study was to examine the categories of child labour children engage in and their influence on their academic work in the Sekondi-Takoradi Metropolis in the Western Region of Ghana. Purposive sampling was used to select 12 JHS teachers whilst the simple random technique was used in the selection of 120 pupils giving a sample size of 132. A questionnaire instrument was used to gather data from the respondents. Descriptive and influential statistics were used to analyse the data. Results indicate that two major categories of pupils; namely, direct offspring and house help offer services to different categories of people in the Sekondi Takoradi Metropolis to earn income. The pupils’ active involvement in child labour activities adversely affected their academic work in the school. Pupils lost interest in attending school and their grades were also poor. It is recommended that The Guidance and Counselling Unit of Ghana Education Service and the National Commission on Civic Education should educate parents on the negative impact of child labour on pupils’ academic work so that parents will not push their children into child labour. It is also recommended that the government, non-governmental organisations, religious organisations, district assemblies and individual philanthropists should support the victims of child labour to reduce the negative impact child labour has on the pupils’ academic work and their social life.
